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.
