Member Data Documentation

collision1

Collision* collision1

Pointer to the first collision object.

collision2

Collision* collision2

Pointer to the second collision object.

count

int count

Length of all the arrays.

depths

double depths[250]

Array of contact depths.

normals

ignition::math::Vector3d normals[250]

Array of force normals.

positions

ignition::math::Vector3d positions[250]

Array of force positions.
