79c3d0abf8 Finally fix #28 - shapes not removed properly on 
A shape added with HC:add*() would be reintroduced to the spatial hash
after HC:remove() when any of shape:move(), shape:rotate() or
shape:scale() was called after the removal.

6bb4ba0e24 Rename intersectionsRay. Less redundancy. 
* intersectionsRay() -> intersectionsWithRay()
* intersectsRay() uses results from intersectionsWithRay()

97ae2d8928 Fix commit adfe9a9a breaking EPA. 2013-09-03 17:13:27 +02:00

adfe9a9a5d Issue #25 (2): Collision detection sometimes hangs. 
Sometimes the expanding polytype algorithm takes a long time to
terminate, e.g. in situations like this:

 .-.
: +-:-+
 '-'  |
  |   |
  +---+

The issue here is that the EPA adds vertices very close to each other,
which makes the separation distance change very slowly. If this is the
case, consider the current separation distance as approximately correct
and continue.

0dc1e6c719 Issue #25: Division by 0 in CircleShape:support(). 
support(A,B, 1,0) returns 0,0 when A and B are touching in a vertex of
both A and B AND this vertex is on the right of A's center (in direction
(1,0)), e.g. this situation:

    .---.
 .-.| B |
: A x---'
 '-'

Then: support(A,B, 1,0) = A:support(1,0) - B:support(-1,0) = x - x = 0

Since CircleShape:support(dx,dy) normalizes dx,dy this will result in a
division by 0 error in the subsequent execution of the GJK algorithm.

An early out with result 'not colliding' (in accordance to the other
edge cases) prevents this error.

ed495d3306 Report collisions immediately instead of collecting first. 
Collecting collisions and then reporting leads to confusing behavior
when a previous collision callback resolved the collision, e.g.
platforms in jump in runs pushing the player upwards when standing on
two platforms at the same time.
