Time of impact failure #115

Closed GoogleCodeExporter closed 9 years ago

What steps will reproduce the problem?
1. Use this code in the TimeOfImpact test:

m_shapeA.SetAsBox(25.0f, 5.0f);
m_shapeB.SetAsBox(2.5f, 2.5f);

b2Sweep sweepA;
sweepA.c0.Set(24.0f, -60.0f);
sweepA.a0 = 2.95f;
sweepA.c = sweepA.c0;
sweepA.a = sweepA.a0;
sweepA.localCenter.SetZero();

b2Sweep sweepB;
sweepB.c0.Set(53.474274f, -50.252514f);
sweepB.a0 = 513.36676f - 162.0f * b2_pi;
sweepB.c.Set(54.595478f, -51.083473f);
sweepB.a = 513.62781f - 162.0f * b2_pi;
sweepB.localCenter.SetZero();

2. Run the test

3. Once fixed, run the test without normalizing the angles. Previously this 
lead to an infinite loop.

What is the expected output? What do you see instead?

b2TimeOfImpact returns a false positive for touching.
