Slider
static Joint* Slider(float posx, float posy, float posz, float pinx, float piny, float pinz, Entity* child, Entity* parent=NULL)
Syntax
- static Shape* PolyMesh(Surface* surface)
Parameters
- posx: the x component of the joint position.
- posy: the y component of the joint position.
- posz: the z component of the joint position.
- pinx: the x component of the joint pin.
- piny: the y component of the joint pin.
- pinz: the z component of the joint pin.
- child: the child entity.
- parent: the parent entity. This may be NULL.
Returns
Returns a new joint.
