Building considirations

To run without error:

• Add Empty game object with a data handler script attached.
• Add Empty game object with TickEventPublisher script.
• Ask Brage: Add a graph
• Attach an AnimalSelectionPanel.prefab to AnimalSelectPanel in the cameras CameraController script. (AnimalSelectionPanel should be added to the main Canvas gameobject)

Animal gameobject

• Tag: Animal, Layer: Target
• Animal Controller script (e.g. BearController, DeerController etc.)
• Field Of Fiew script
• Hearing Ability script
• Nav Mesh Agent
• Animator
• Transform
• Character Controller

Water gameobject

• Tag: Water, Layer: Target
• Collider of some sort (so that animal's raycast can hit the object)

Plant gameObject

• Tag: Plant, Layer: Target
• Collider of some sort (so that animal's raycast can hit the object)
• Plant Controller script

Render pipeline (to get cel-shading and outline to work)

• To ensure that the Light Weight Render Pipeline is used, check projectSettings/Graphics, and set the object at the top (under Scriptable Render Pipeline Settings) as LWRP (found in Rendering Pipeline folder).
• If LWRP is in use, but a material is pink, ensure its shader is using Shader Graphs/Toon Cel-Shader (except plane, which has to use Universal Render Pipeline - Simple Lit, instead).

Cel-shading

• To change the effect of the cel-shading, each material (found in Rendering Pipeline/Materials) has four sliders and two colors in the inspector.
• Shadow Size and ShadowBlend affect the internal shadows on the object. Both affect shadow strength, but ShadowBlend also adds a bit of diffusion to the shadow. Can also change the color of the shadow.
• Rim light adds a very faint shine effect when viewed at an angle, and has a dithering effect. Lighter rim light color is more visible than dark.

Outline

• To change the thickness of the outline affecting all objects, go to RenderingPipeline/Shaders/OutlineToon_SobelBlit.
