Recipes

Creating a simple character :

1. in Unity 6000.0.23f1 (or higher), create a new project and import Corgi Engine v9.3 via the Package Manager
2. open the MinimalLevel demo scene
3. create an empty game object, position it at -10,-3,0, name it MyTestCharacter
4. create a new empty child game object to the MyTestCharacter node, add a SpriteRenderer to it, set its Sprite to Adventurer_0, name it MyModel
5. on the MyTestCharacter node, add a Character component, press the AutoBuildPlayerCharacter button at the bottom of it
6. drag your MyModel into the Character’s inspector’s CharacterModel field
7. edit the BoxCollider2D’s size to 0.8,0.8

Setting it as the playable character in our scene :

1. drag the MyTestCharacter node into your project to make it a prefab, then remove it from the scene
2. select the LevelManager, and drag your newly created prefab into its PlayerPrefabs[0] slot
3. press play, enjoy your newly created character
4. make sure you read the rest of the documentation to learn more about how to create more complex characters

1. Create a new empty project using 2D or 3D as the Template
2. Go to Window > Package Manager, then from the top left dropdown pick “My Assets”, find Corgi Engine in the list and import it the project (it has to be in an empty project, not an existing one)
3. You will be warned that importing the Corgi Engine will overwrite your current project settings (that’s normal), click on Import.
4. This will take a bit of time.
5. Once this is complete, you’ll get a prompt saying “This Unity Package has Package Manager dependencies”. This is also normal, click on “Install/Upgrade”.
6. After that you’ll get a list of the contents of the engine, don’t touch anything, and click on Import in the bottom right corner.
7. Import will also take a while. Once import is complete, you’re ready to use the engine. Have fun!

The engine doesn’t do any rendering, it’ll work with any render pipeline.

The demos are made using the Standard Render Pipeline, as it’s still the only stable one, and the most common denominator, but you can use any RP you prefer. If you decide to use URP or HDRP in your project, the best approach would be to keep another project at hand, using SRP, to test the engine’s demos in, while you implement your own game in URP/HDRP.

Below are steps to install the Corgi Engine on a URP project. It’s recommended to have at least basic knowledge of render pipelines before picking URP or HDRP, considering the many quirks of these two render pipelines.

1. Create a new project, using the URP template
2. Import the Corgi Engine from the Package Manager
3. Via the package manager, update other packages if you have to (Pixel Perfect typically can cause issues with URP on some of its versions)
4. Open the MinimalLevel demo scene (or any scene)
5. Open your project settings (Edit > Project Settings), in Graphics, at the top of it, set a Scriptable render pipeline asset (the URP default template usually comes with a few, pick the HighQuality one)
6. In the scene, select the UICamera, on its Camera component, set RenderType to Overlay
7. Select the MainCamera (called Regular Camera in some scenes), at the bottom of its Camera component, add the UICamera to its Stack
8. If you want to convert all (or most) materials to URP, simply go to Edit > Render Pipeline > Universal Render Pipeline > Upgrade Project Materials to URP Materials, press play, the demo will play. Note that you’d also have to port post processing effects, as Unity went with a different system (volumes) on URP/HDRP.

Some of my materials are all pink!

While most of the materials used in the engine’s demos will display fine on all RPs, a few demos, like the NewCorgi3D one, use custom shaders, and these will break in HDRP or URP. Thankfully, you can convert them fairly easily, like so :

1. select all materials that are using a BiRP shader (typically, the materials under Demos/Corgi3D/Materials)
2. in their inspector, at the top, set their shader to Standard
3. then, go Edit > Rendering > Materials > Convert Selected Built-In Materials to URP They won’t look just as good as they would have in BiRP, but will let you enjoy the demo just fine.

1. In this example we’ll work in MinimalCinemachineZones, and for that we’ll disable all existing CinemachineZones. Feel free to adapt sizes and positions to your own context.
2. Create a new empty gameobject, name it MyZone, position it at -71,-2.5,0
3. Add a BoxCollider2D to it, set its size to 31,11.5
4. Add a CorgiCinemachineZone component to it
5. Create an empty child object, name it VirtualCamera
6. Find a virtual camera you like. We’ll use the one under MinimalCameraRig, right click on the CinemachineVirtualCamera component, copy component, and then “paste component as new” on our empty VirtualCamera object
7. At the MyZone level, drag the new VirtualCamera into the VirtualCamera slot. As this is our first zone in our level, we’ll also check CameraStartsActive. We want the Player to activate this zone, so we’ll select the Player layer in the Trigger Mask dropdown, and we’ll check SetupConfinerOnStart to let the engine handle all the complex confiner setup.
8. Press play, your camera will now be confined to that zone.
9. Exit play mode, and duplicate MyZone into a new MySecondZone object. Move it to -40,-2.5,0
10. Notice at the bottom of the inspector you can change the zone’s gizmo color, pick one you like
11. Select the second zone’s virtual camera, and under Lens, set the OrthoSize to 3
12. Press play, move right, you’ll transition to the new zone, with a more zoomed in camera
13. You can now add more zones to cover your whole level, position them however you like
14. If you want to tweak camera transitions between zones, that’ll be on the CinemachineBrain on your camera (in this case the Regular Camera object under MinimalCameraRig). You’ll want to change the DefaultBlend and its associated duration.
