Member Function Documentation

float32 Engine::RayCastClosestCallback::ReportFixture ( b2Fixture *  fixture, const b2Vec2 &  point, const b2Vec2 &  normal, float32  fraction  )

override

Function used by Box2D to tell the Callback class that the ray has collided with a fixture. Box2D Comments: By returning the current fraction, we instruct the calling code to clip the ray and continue the ray-cast to the next fixture. WARNING: do not assume that fixtures are reported in order. However, by clipping, we can always get the closest fixture.

Parameters

fixture	The fixture the ray intersected with
point	The point the ray intersected with the fixture
normal	The normal of the surface the ray intersected with
fraction	???Investigate Box2D for this???

Returns

Number determines the query behaviour of the ray, 1 continue, 0 stop and return fraction parameter to get the closest
