| 3 | * Definition of a collision event |
---|
[9888] | 4 | * |
---|
| 5 | * A collision event represents a collision of two bouning boxes. Every CollisionEvent belongs to a Collision object that |
---|
| 6 | * represents the collision of two WorldEntities. |
---|
| 7 | * |
---|
| 8 | * There are different types of collisions: obb collisions and bsp collisions. Both collision types use different techniques |
---|
| 9 | * to represent collisions. This is why this class saves bounding boxes from the OBB as well as the planes from BSP. |
