◆ b2Distance()
| void b2Distance | ( | b2DistanceOutput * | output, |
| b2SimplexCache * | cache, | ||
| const b2DistanceInput * | input | ||
| ) |
Compute the closest points between two shapes. Supports any combination of: b2CircleShape, b2PolygonShape, b2EdgeShape. The simplex cache is input/output. On the first call set b2SimplexCache.count to zero.

◆ b2ShapeCast()
| bool b2ShapeCast | ( | b2ShapeCastOutput * | output, |
| const b2ShapeCastInput * | input | ||
| ) |
Perform a linear shape cast of shape B moving and shape A fixed. Determines the hit point, normal, and translation fraction.
- Returns
- true if hit, false if there is no hit or an initial overlap
