Raycasting support

[vveisard]

Raycasting would be an excellent addition and within scope of the package.

what user api would you have in mind

it is quite easy to implement:

this is how I would do this: (not tested)

• create a temporary line (2 point polygon),
• add to system,
• check line's potentials using BVH,
• iterate over potentials to check exact collisions,
• add collisions to array,
• select closest point to start of array,
• remove temporary line from system.

@sineprime what would you expect from such Raycasting api ?

what example function names / functionalities would you want to have ?

[Prozi]

I've decided to keep it simple and went with

system.raycast(start: Vector, end: Vector): { point: Vector; collider: TBody } | null

and included it inside the tank test demo https://prozi.github.io/detect-collisions/demo/

closing as working
