Examples

B3.b3SetLengthUnitsPerMeter(100.0f); // centimetres, before any other call
float slop = ScaledConstants.B3_LINEAR_SLOP; // 0.5, not 0.005

Remarks

In the C headers these are macros that expand to a call to b3GetLengthUnitsPerMeter(), so their value depends on what the application passed to b3SetLengthUnitsPerMeter at startup. They are properties here for the same reason: capturing them in a const would silently freeze the default of one unit per metre.

Reading any of these calls into the native library.

Properties

B3_CONTACT_RECYCLE_DISTANCE

The default distance at which contact points are recycled.

B3_HUGE

The bound used to detect bad values. Positions beyond this are treated as errors.

B3_LINEAR_SLOP

A small length used as a collision and constraint tolerance, in metres.

B3_MAX_AABB_MARGIN

The upper bound on the margin used to fatten bounding boxes in the dynamic tree.

B3_MESH_REST_OFFSET

The rest offset applied to mesh contacts to reduce ghost collisions.

B3_MIN_CAPSULE_LENGTH

The minimum length of a capsule. Shorter capsules should be spheres.

B3_OVERLAP_SLOP

The distance at which shapes are considered overlapped.

B3_SPECULATIVE_DISTANCE

The distance within which speculative contacts are generated.
