Properties | |
radius The Radius of the circle |
|
offset Offset. (body space coordinates) |
|
body The body this shape is attached to (Inherited from pymunk.Shape) |
|
collision_type User defined collision type for the shape. See add_collisionpair_func function for more information on when to use this property (Inherited from pymunk.Shape) |
|
elasticity Elasticity of the shape. A value of 0.0 gives no bounce, while a value of 1.0 will give a 'perfect' bounce. However due to inaccuracies in the simulation using 1.0 or greater is not recommended. (Inherited from pymunk.Shape) |
|
friction Friction coefficient. pymunk uses the Coulomb friction model, a value of 0.0 is frictionless. (Inherited from pymunk.Shape) |
|
group Shapes in the same non-zero group do not generate collisions. Useful when creating an object out of many shapes that you don't want to self collide. Defaults to 0 (Inherited from pymunk.Shape) |
|
layers Shapes only collide if they are in the same bit-planes. i.e. (a.layers & b.layers) != 0. By default, a shape occupies all 32 bit-planes, i.e. layers == -1 (Inherited from pymunk.Shape) |
|
sensor A boolean value if this shape is a sensor or not. Sensors only call collision callbacks, and never generate real collisions. (Inherited from pymunk.Shape) |
|
surface_velocity The surface velocity of the object. Useful for creating conveyor belts or players that move around. This value is only used when calculating friction, not resolving the collision. (Inherited from pymunk.Shape) |

Method Details |
|
Unsafe set the radius of the circle. WARNING: This change is only picked up as a change to the position of the shape's surface, but not it's velocity. Changing it will not result in realistic physical behavior. Only use if you know what you are doing! |
