Previously some rays that originated outside of the `CircleHitbox` were
counted as inside, this solves that and adds an example of how to use
the `isInsideHitbox` functionality (thanks to @wurzelsand).
Closes#3063
This change makes it possible to have the collision detection system further down in the tree than on the FlameGame, this enables you to have collision detection on the World component for example.
Today it doesn't work if you have several worlds where the components are overlapping across the worlds, since the hitboxes live on top level.
So now you can use a World like this:
class CollisionDetectionWorld extends World with HasCollisionDetection {}
and all hitboxes added in there will only react with other hitboxes added to that world.
This PR adds an optional parameter to raycast API called maxDistance. Using this parameter users can control the limit within which raycast scans for hits.
This PR adds two updates.
It updates the flame_forge2d to latest version i.e on pub.dev in examples and padracing projects.
Adds a bouncing ball example in the collision detection examples demonstrating a simple example of collision and bouncing of a ball from the walls around it.
This PR implements raytracing and raycasting for the built-in hitboxes.
If you pass in your own collision detection system to the HasCollisionDetection mixin you have to change the signature of that to: CollisionDetection<ShapeHitbox>instead of CollisionDetection<Hitbox>.
