Class HitBox2DSystem

This system tests for overlaps between all components under all cameras in the world.

Inheritance

System.Object

HitBox2DSystem

Namespace: Unity.Tiny.HitBox2D

Syntax

public class HitBox2DSystem : ComponentSystem

Remarks

It adds HitBoxOverlapResults components to entities that overlap others, and removes them from entities that no longer overlap others.

Overlaps are only detected between objects that overlap under the same camera.
