• Improved usability of trigger events and collision events:
  • Events (StatefulTriggerEvent and StatefulCollisionEvent) have states indicating overlap or colliding state of two bodies:
    • Enter - the bodies didn't overlap or collide in the previous frame, and they do in the current frame
    • Stay - the bodies did overlap or collide in the previous frame, and they do in the current frame
    • Exit - the bodies did overlap or collide in the previous frame, and they do not in the current frame
  • Events (StatefulTriggerEvent and StatefulCollisionEvent) are stored in DynamicBuffers of entities that raise them
  • Reworked following demos to demonstrate new trigger event approach:
    • 2d1a. Triggers - Change Material
    • 2d1b. Triggers - Portals
    • 2d1c. Triggers - Force Field
  • 2d2a. Collision Events - Event States added to demonstrate new collision event approach.
• Exposed trigger events and collision events of CharacterController
• CharacterController body is now using a CollisionResponse.None collision response on its body to avoid reporting duplicated collision/trigger events coming from the physics engine.
• Demos/2. Setup/2b. Motion Properties/2b1. Motion Properties - Mass, Tests/Pyramids and a group of demos under Tests/Stacking now showcase new solver stabilization features/strengths and weaknesses/trade-offs.
