Recipes | TopDown Engine Documentation

This page lists a few 'recipes' that will teach you in a few steps how to do common tasks.

Introduction

Want to get started quickly with the TopDown Engine? This page contains simple steps you can follow for a number of basic situations, no explanations, just quick steps. Don’t hesitate to check the rest of the documentation to learn more about how the engine works! Note that most of these will provide TDE / Unity versions, that’s just to provide the context they were first written in. But it’s safe to assume that they should work on any higher versions of both Unity and TDE.

Creating a basic 2D playable character

fresh install of 2019.3.3f1
import TDE v1.10.1
open Minimal2D demo scene
create a new, empty game object, position it at 40,-20,0, call it Test
create a new sprite object, set its Sprite to Adventurer_0, sorting layer to Characters, nest it under Test, at 0,0,0
on Test, add a Character component
press AutoBuild Player Character 2D
drag the NewSprite into the CharacterModel slot
under CharacterOrientation2D, set facing mode to MovementDirection, check Model Should Flip
open the Koala prefab, copy the footsteps node
paste in your scene
nest it under Test, at 0,0,0
press play

Creating a basic 2.5D playable character

If you want to create a character that evolves in a 3D world, but appears as a sprite (think Paper Mario), you can do it like so :

fresh install of 2019.4.39f1
import TDE v3.0
open MinimalScene3D demo scene
create a new, empty game object, position it at 0,0,0, call it Test
create an empty child, name it Model
create a new sprite renderer, set its sprite to Koala_Idle_0, drag it under Model, position it at 0,0,0, name it MySprite
on Test, add a Character comp
press AutoBuild Player Character 3D
on Test’s Character component, drag the Model node into the CharacterModel slot
on Test, remove the CharacterOrientation3D component, add a CharacterOrientation2D, set FacingMode:MovementDirection, ModelShouldFlip:true
on MySprite, add a MMBillboard component, NestObject:false, OffsetDirection:0,0,1
drag the Test object in your Project panel to make it a prefab, remove it from the scene
select the LevelManager, drag that new prefab into the first array entry of PlayerPrefabs press play, enjoy your new 2.5D friend

Creating a basic 3D playable character

in a stable version of Unity and the latest version of TDE
open MinimalScene3D demo scene
create a new, empty game object, position it at 0,0,0, call it Test
create a new cube, drag it under Test, position it at 0,0,0, name it Model, remove its BoxCollider
on Test, add a Character component
press the AutoBuild Player Character 3D button at the bottom of its inspector
on the CharacterController component, set Height to 1
on the Character component, drag the Model into the CharacterModel slot
under CharacterOrientation3D, set Rotation Mode to MovementDirection, drag the Model into the Movement Rotating Model slot
drag that Test object in your Project panel to make it a prefab, remove it from the scene
select the LevelManager, drag that new prefab into the first array entry of PlayerPrefabs
press play, enjoy your new friend

Extra steps : adding an Animator

on the Model object inside your character, add an Animator component
in your Project panel, create a new AnimatorController, name it TestAnimatorController, drag it into the Animator’s Controller slot
on the same object, add a CharacterAnimationParametersInitializer component, press its AddAnimationParameters button (the component disappears, that’s normal)
at the top level of your character, drag the Model into the Character component’s CharacterAnimator slot
save your prefab, press Play
in the Hierarchy panel, select the Model object, double click on its Controller in its Animator component, this will open the Animator panel, there you can see that its various animation parameters update. You can use all of these to setup your transitions between animations.

Creating a basic 3D enemy

fresh install of 2019.3.3f1
import TopDown Engine v1.10.1
open Loft3D demo scene
create an empty game object, set it at -9.5,1.5,0
create a cube, set its scale to 2,2,2, set it under the empty
rename the empty to “Test”
on Test, add a Character component
press the Autobuild AI Character 3D button
in the Character inspector, set the CharacterModel to the Cube
press play, grab the shotgun next to you, enjoy

Creating a simple projectile weapon

fresh install of TDE v1.10.1 on 2019.3.3f1
open the MinimalScene3D demo scene
create a new empty game object, name it MyWeapon
add a ProjectileWeapon component to it
add a WeaponAim3D component to it, set AimControl:PrimaryMovement
add a MMSimpleObjectPooler component, MutualizeWaitingPools:true, GameObjectToPool:LoftAssaultRifleBullet
create a new cube, remove its BoxCollider, nest it under MyWeapon at 0,0,0, name it MyWeaponModel
drag MyWeapon into the project panel somewhere, to make it a prefab
select the MinimalCharacter prefab, set MyWeapon as its InitialWeapon
press play, enjoy your cube gun!

Setting up checkpoints

fresh install of TDE 3.4 on 2020.3.48f1
open Loft3D demo scene, add a Cube at 0,0,45, name it MyCheckpoint, on its BoxCollider, set IsTrigger:true
add a Checkpoint component to it, CheckPointOrder:1 (the initial spawn point uses 0)
edit the DeathSplash / ButtonRestart to have it call RestartLevel instead of ReloadLevel (that particular demo is set to reload the entire scene by default, KoalaDungeon on the other hand isn’t)
press play, enter the level, walk to the Cube and touch it, then get yourself killed
when the death splash appears, press the RestartLevel button, you respawn at the new checkpoint’s position

Creating an IK powered weapon

create a new, empty project, in Unity 2019.4.17f1
import TopDown Engine v1.10.1
open the Loft3D demo scene
create a new empty game object in that scene, name it CubeGun
create a new cube, nest it under the CubeGun node, reset its transform
set the scale of the cube to 0.2,0.5,1.5
on the CubeGun, add a ProjectileWeapon component
unfold its Projectiles section, set the spawn offset to 0,0,1
on the CubeGun, add a MMSimpleObjectPooler, drag the AssaultRifleBullet prefab from the Project view to its GameObjectToPool slot
on the CubeGun, add a WeaponAim3D component, set its AimControl to SecondaryThenPrimaryMovement, and its weapon rotation speed to 0
drag the CubeGun into your Project panel to make it a prefab.
select the LoftSuit prefab, and in its CharacterHandleWeapon component, drag the CubeGun in its InitialWeapon slot
press play
you can now move around and shoot with your cube weapon, which is correctly positioned

From there, if you want to setup IK, you’d need to do the following :

make sure IK is correctly setup on your character (see the IK section of the documentation), on the LoftSuit character that’s already the case
open the CubeGun prefab
create a new empty game object, nest it under CubeGun, name it Left, position it at -0.15,0,-0.1
create a new empty game object, nest it under CubeGun, name it Right, position it at 0.1,-0.1,-0.65
on the CubeGun’s ProjectileWeapon, under the IK section, drag Left into the LeftHandHandle slot, and Right into the RightHandHandle slot
save your prefab, press play
your character’s hands are now correctly positioned

Creating a simple projectile weapon and its projectiles

fresh install of TDE 3.5 on 2020.3.48f1
open the Loft3D demo scene
create a new empty at 0,0,0, name it MyProjectile (layer Projectile), add a Projectile component to it (LifeTime:1, BoundsBasedOn:Collider, Speed:300), add a Health component, add a DamageOnTouch (TargetLayerMask:Obstacles, DamageTakenEveryTime:50), add a BoxCollider (isTrigger:true, size 0.1,0.1,1), add a Rigidbody (isKinematic:true)
add a Cube under it, remove its BoxCollider, set its scale to 0.1,0.1,1, make MyProjectile a prefab
create a new empty game object, name it MyWeapon
add a ProjectileWeapon component to it, TimeBetweenUses:0.1
add a WeaponAim3D component to it, set AimControl:PrimaryMovement
add a MMSimpleObjectPooler component, MutualizeWaitingPools:true, GameObjectToPool:MyProjectile, make it a prefab
select the LoftSuit prefab, set MyWeapon as its InitialWeapon
press play, enjoy your long cube gun!

Setting up auto aim and auto shoot

in a fresh install of TDE v2.4 on 2019.4.37f1
open the Koala2D demo scene
select the KoalaRifleAmmoBased prefab in your Project panel
add a WeaponAutoAim2D component to it, set TargetsMask to Enemies
press play, move up to grab the rifle picker and ammo, your gun will now auto aim at enemies around your character, and revert back to regular, manual aim otherwise
to add auto shoot to it, exit play mode, add a WeaponAutoShoot component to it. You’ll also want to uncheck TimeBetweenUsesReleaseInterruption on your ProjectileWeapon (under Use).
press play again, you will now auto shoot at targets the auto aim catches

Creating a door that requires a key to open

In this example we’ll create a “door” (technically a cube that disappears), and we’ll associate it to an interactive zone that will require a key to open.

fresh install of TDE v2.1 on Unity 2019.4.28f1
open Loft3D demo scene

Creating the door

create a new Cube, name it “Door”, position it at -15,0.5,0, set its scale to 1,5,1
create a new Cube, name it “DoorZone”, set its BoxCollider to trigger, position it at -14,0,0
add a KeyOperatedZone to the DoorZone object, add an event to OnActivation, drag the Door into its slot, and select GameObject > SetActive (here we’re just making the door disappear, but if you had a door with an actual Open() method, that’s where you’d bind it too)
at the bottom of its inspector, set RequiresKey to true, and in the KeyID field put “MyKey”

Creating the key

in your project, create a folder, name it Resources
in it, right click, Create > More Mountains > Top Down Engine > Inventory Engine Key, name it MyKey
set its ItemID to MyKey, description to “a key”, icon to Koala_Items_MetalKey, TargetInventoryName to SuitMainInventory
in the Loft3D scene, create a new sphere, name it “MyKeyPicker”, set its collider to IsTrigger, position it at -9,1,0
add a ItemPicker component to it, drag the MyKey asset we’ve created into its Item slot, add a PickableItem, check DisableObjectWhenDepleted

Testing

press play, DO NOT grab the sphere/key, and walk on top of the small cube next to our “door” (our DoorZone object), press space, nothing happens, as we don’t have the required key
move right, walk on top of the sphere/key to grab it, press I to open your inventory, notice it’s now in there
walk on top of the small cube next to the “door”, press space, notice the Door disappears as expected

Getting the new input system to work

fresh install of the latest Unity stable version (2019.4.17)
import TDE v1.10.1
import InputSystem 1.0.1 via the package manager
open the MinimalScene3D_InputSystem_Multiplayer demo scene
Unity usually loses some references to the new input system assets, so you may have to bind them again. That’s done like in any project, inside the TopDownEngineInputActions make sure that the Keyboard and Gamepad schemes have the right bindings (Keyboard should be Keyboard and Mouse, gamepad should be gamepad).
on the InputSystemManager_Player1 (and 2), bind events if references were lost
press play

Switching from the old to the new input system in an existing demo scene

fresh install of TDE 3.1.1 on 2019.4.40f1
from the package manager, import InputSystem 1.5
open MinimalScene2D
on its KoalaUICamera, remove the InputManager component
on a new empty, add an InputSystemManager
in the hierarchy, select the EventSystem object, in its inspector, click its “Replace with InputSystemUIInputModule” button
press play in your editor, your scene is now using the new input system!

Setting up two characters with separate input

create a new project in 2019.4.19f1
import TDE v1.10.1
open the MinimalScene3D demo scene
select the LevelManager, set its PlayerPrefabs array size to 2
select the Suspenders prefab, set its PlayerID to Player2, drag it in the LevelManager in slot 2 (element 1)
select the UICamera, copy the InputManager comp, paste it as new
in the newly pasted InputManager, change the PlayerID to Player2
press play, you can now control the minimal char with wasd, the suspenders with arrows

Creating a weapon with ammo

create a new project in Unity 2019.4.19f1
import TDE v1.10.1
open the KoalaDungeon demo scene
create a new empty object, name it TestWeapon
add a ProjectileWeapon component to it, under Magazine, check MagazineBased, set MagazineSize to 10, under Settings check InitializeOnStart
add a MMSimpleObjectPooler component to it, drag a KoalaRifleBullet in its GameObjectToPool slot (for these steps I didn’t create new ammo, it’ll be using the rifle ammo)
add a WeaponAmmo component to it, set AmmoID to KoalaRifleAmmo, AmmoInventoryName to KoalaMainInventory, Max Ammo to 100, and make sure ShouldLoadOnStart is checked
drag the TestWeapon object into your project to make a prefab out of it, remove it from the scene
in a Resources folder, right click > MoreMountains > TopDownEngine > InventoryWeapon to create a weapon asset
name it TestWeapon, set its ItemID and ItemName to TestWeapon, set its TargetInventoryName to KoalaMainInventory, check its Equippable checkbox, set its TargetEquipmentInventoryName to KoalaWeaponInventory, in its EquippableWeapon slot, drag the TestWeapon prefab, set its ItemClass to Weapon
in the scene, select the KoalaRiflePicker, and in its ItemPicker comp, drag the TestWeapon asset
press play, move over the rifle and ammo picker to grab them
press T, this will equip the weapon (it won’t look like much, we didn’t setup its visuals or anything), press E to shoot, do it 10 times to empty the clip, press R to reload, do it again, weapons empty and refill as expected

Creating a prefilled inventory

create a new project in Unity 2019.4.19f1
import TDE v1.10.1
open the Suspenders prefab
in its CharacterInventory, set AutoPick items to 3 : handgun ammo 10, assault rifle 1, assault rifle ammo 10
in AutoEquipWeaponOnStart, drag the Handgun
open the Loft3D demo scene, press play, you now spawn with a handgun in hand, press T, you now have an assault rifle, press T again, now it’s a handgun, repeat as much as you want

Setting up projectiles for damageables and non damageables

create a new project in Unity 2019.4.17f1
import TopDown Engine v1.10.1
open the MinimalScene3D demo scene
select the MinimalCharacter prefab, in its CharacterHandleWeapon component, drag the AssaultRifle prefab
in the scene, select the Border node (under Level/Models/), set its y value to 0.5
select the AssaultRifleBullet prefab, open it
in it you’ll find two ready made feedbacks, in the HitDamageable one, add a DebugLog feedback, set its debug message to “hit damageable”
in the HitNonDamageable one, add a debug log feedback, set its debug message to “hit non damageable”
save the prefab, go back to the scene
create a new cube, set its position to 3.5,1,-8, add a Health component to it, change its layer to Enemies
press play, shoot at the cube, then shoot at the walls, you should see something like this in your console

Setting up a weapon model enabler

in a fresh install of Unity 2019.4.19f1, import TDE v1.10.1
open the Koala prefab, create an empty child, name it TestWeaponModel, add a SpriteRenderer, set the sprite to HornyBlue_0, sorting layer Characters, order in layer 1, move it to 0,2,0
add an animator to it, set the controller to HornsBlueAnimator
add a MMAnimatorMirror component (that will replicate the state of animation parameters from animator A to animator B). Set its SourceAnimator as the KoalaModel node’s animator, and TargetAnimator as the animator component just above it
disable the TestWeaponModel node
on the Koala node, add a WeaponModelEnabler, set Bindings’ size to 1, drag the TestWeaponModel into the slot, WeaponAnimationID to 10 (arbitrary unique ID)
select the KoalaRifleAmmoBased prefab, unfold its AnimationParametersName panel, set the WeaponAnimationID to 10
in the same panel, set the StartAnimationParameter to SwordAttack (the parameter that triggers an attack on the Horns animator)
open the KoalaModel’s KoalaAnimatorController animator controller, add a SwordAttack bool parameter to it
open the KoalaDungeon demo scene, press play, grab the assault rifle above the spawn point, the weapon model (the blue dude) appears
shoot, the blue dude will attack

That’s just one of the ways to do it, you could also have a single animator (in this case the Koala one) in which you’d have animations for the weapon/blue dude, which would always play but only be visible if the weapon model enabler is activating the model.

Setting up damage on touch

create a new, empty project in Unity 2019.4.22f1
import TDE v1.10.1
open MinimalScene3D
create a new cube, position it at -5,0-,5
set its box collider to trigger
add a DamageOnTouch component to it, set its TargetLayerMask to Player, set its DamageCausedKnockbackForce to 20,20,0
press play, walk towards the cube, you’ll get knockback when colliding with it

Creating a simple, turret-like, rotating AI

create a new project in Unity 2019.4.22f1
import TDE v1.10.1 (check version in the readme)
open the MinimalScene3D
create a new empty game object, name it Test
under it, create a new cube, name it Model
on the Test node, add a Character component, press its Autobuild AI Character 3D button, drag the Model node into the Character’s CharacterModel slot
on the CharacterOrientation3D uncheck ShouldRotateToFaceWeaponDirection, check ForcedRotation, bind the Model into the MovementRotatingModel slot, set RotationMode to MovementDirection,

on the AIDecisionDetectTargetRadius3D comp, set the TargetLayerMask to Player
on the AIActionRotateTowardsTarget3D, check LockRotationX
on the AIBrain, create a new state, call it Wait, set AIActionDoNothing as its action, AIDecisionDetectTargetRadius3D as its transition’s decision, TrueState:Rotate
create a second state, call it Rotate, set its Action as AIActionRotateTowardsTarget3D
press play, enjoy your tiny AI!

Creating a turret-like enemy AI that shoots at the player

fresh install of TDE v2.4 in 2019.4.37f1
open the MinimalScene3D demo scene
create a new, empty game object, position it at 0,0,0, call it Test
create a new cube, drag it under Test, position it at 0,0,0, name it Model, remove its BoxCollider
on Test, add a Character component, press AutoBuild AI Character 3D
on the Character component, drag the Model into the CharacterModel slot
under CharacterOrientation3D, set Rotation Mode to Weapon Direction, drag the Model into the Movement Rotating Model slot
add a CharacterHandleWeapon ability, set the LoftAIAssaultRifle as its InitialWeapon
add an AIBrain, AIActionDoNothing, AIDecisionDetectTargetRadius3D (TargetLayerMask:Player), AIActionShoot3D, AIActionRotateTowardsTarget3D
on the AIBrain, create two states : Detect (DoNothing and DetectRadius, TrueState:Shoot) and Shoot (Actions: Rotate and shoot)
of course that AI will never stop shooting once it’s detected the player, but from there you can modify its brain to have it do more things if you’d like

Creating a simple AI that will follow and rotate towards the player

create a new project in Unity 2019.4.28f1
import TDE v2.1
open the MinimalScene3D
create an empty game object, name it “MyChar”, position it at 0,0,0
create a cube, position it at 0,0,0, nest it under MyChar, name it MyModel
via the AddComponent dropdown in its inspector, add a Character component to MyChar, press AutoBuild AI Character 3D
in CharacterOrientation3D, drag MyModel to the MovementRotatingModel slot, set rotation mode to MovementDirection
add an AI brain, AIDecisionDetectTargetRadius3D, AIActionMoveTowardsTarget3D, AIActionRotateTowardsTarget3D
in the brain, add a new state, name it Detect, add a transition to it, set the decision to DetectTargetRadius, TrueState to Move
add a new state, name it Move, no Transition, set its Actions to Move and Rotate towards target
in the Detect target radius set the TargetLayerMask to Player
press play, move around, AI follows and rotates towards target

Setting up 2D cones of vision powered AIs

fresh install of TDE v1.10.1 in Unity 2019.4.25f1
open KoalaDungeon
select the first ninja to the left, right click, unpack it completely
rename it to NinjaWithCone (or whatever), and make a prefab of it
open the Koala prefab, select its ConeOfVision node, copy it
open the NinjaWithCone prefab, paste the ConeOfVision into it, put it at the same level as the NinjaModel or the Feedbacks (under the top level), position it at 0,0,0
at the top level of that prefab, remove AIDecisionTargetRadius2D
add a MMConeOfVision2D, set ObstacleMask to Obstacles, TargetMask to Player, and drag the ConeOfVision into the VisionMeshFilter slot at the bottom
add a AIDecisionDetectTargetConeOfVision2D, and in the AIBrain, change the first State’s transition’s decision to AIDecisionDetectTargetConeOfVision2D
press play, walk into the Ninja’s cone, notice it acquires the Player as the target and starts attacking it

Bonus steps if you want the cone to move too :

add an AIActionRotateConeOfVision2D
add an AIActionMoveRandomly2D
in the AIBrain’s first state, replace the action (AIActionDoNothing) with AIActionMoveRandomly2D, and add a second action, and make it AIActionRotateConeOfVision2D

Setting up a hitscan weapon

fresh install of TDE v2.2 on Unity 2019.4.29f1
open KoalaDungeon
create an empty game object, name it TestHitscan
create an empty child to it, name it Model, add a SpriteRenderer to it, set its sprite to Koala_Weapons_Rifle, SortingLayer:Above
on the top level object (TestHitscan), add a HitscanWeapon component, under HitscanSpawn, set the projectile spawn offset to 0.8, .1,0
under the Hitscan section, set Mode to TwoD, HitscanTargetLayers to Enemies, Obstacles
add a WeaponAim2D component, set its AimControl to Mouse, WeaponRotationSpeed:0
drag the TestHitscan object into your project to make it a prefab, remove it from the scene
select the Koala prefab, drag the TestHitscan prefab into its CharacterHandleWeapon’s InitialWeapon slot
press play, you’re now wielding a weapon that will damage/destroy enemies/clay pots in a straight line when aimed at them (now you can start working on its feedbacks to make it feel better!)

Setting up a character model switch ability

in a fresh install of TDE v2.1 on Unity 2019.4.29f1
open the MinimalScene2D demo scene
open the MinimalCharacter2D prefab
create a new empty game object to it, name it AltModel, to it, add a SpriteRenderer, and set its Sprite to Adventurer_0, then set its position to 0,0.4,0, and disable the object
at the top level (MinimalCharacter2D) add a CharacterSwitchModel ability
add two entries to its CharacterModels array, drag the MinimalCharacterModel to its first slot, and the AltModel node to its second slot
save the prefab, press play on the MinimalScene2D, you can now move around, and switch models by pressing P

Creating a new loading screen

fresh install of TopDown Engine v2.1 on Unity 2019.4.28f1
duplicate the LoadingScreen demo scene, name it NewLoadingScreen
add it to your build settings (file, build settings, drag your NewLoadingScreen into the “Scenes in Build” panel)
open it, select the Main Camera, and on its Camera component, let’s change the background color to some red (you can make other changes in the scene if you want to, but that red is how we’ll make sure we’re using the correct one)
save the scene
open Minimal2DDoors1, in its LevelManager, set the LoadingSceneName to NewLoadingScreen
press play, move up/right through the green door, then move right until you see a blue gate, enter it (press space), notice we’re loading our new scene using our newly created loading screen

Setting up a Weapon Model

open the Colonel demo scene

Setup the weapon model :

under its HandR node, create an empty object, name it MyWeaponModel
add a WeaponModel comp to it, set its WeaponID to MyWeapon
under it, create a new cube, remove its box collider, set its scale to 0.003,0.003,0.003
on MyWeapon’s WeaponModel inspector, drag the cube into the TargetModel slot
press play, notice the cube disappears, that’s normal, its weapon is not equipped

Setup the weapon :

duplicate the Loft3D’s AssaultRifle prefab, name it MyWeapon
in its ProjectileWeapon’s ID section, set WeaponName to MyWeapon
open that new prefab, remove its ModelContainer node and everything under it, remove the feedback too
clear its ProjectileWeapon’s animators and animation parameter names
at its top level remove the animator
save the prefab, and on the Colonel’s CharacterHandleWeapon, assign it as its InitialWeapon
press play, you now have a nice shooting cube
