Description
Sets the body type.
r3d.Body:setType(type)
There are three types of bodies: static, kinematic and dynamic.
A static body has infinite mass, zero velocity but its position can be changed manually. Moreover, a static body does not collide with other static or kinematic bodies.
A kinematic body has infinite mass, its velocity can be changed manually and its position is computed by the physics engine. A kinematic body does not collide with other static or kinematic bodies.
A dynamic body has non-zero mass, non-zero velocity determined by forces and its position is determined by the physics engine. Moreover, a dynamic body can collide with other dynamic, static or kinematic bodies.
For instance, you can use a static body for the floor, a kinematic body for a moving platform and a dynamic body for a rock that could fall on the floor.
When you create a new body in the world, it is of dynamic type by default.
Parameters
type: (number) the new body type, must be one of the following:
- r3d.Body.STATIC_BODY 0
