Used to create a shape. This is a temporary object used to bundle shape creation parameters. You may use the same shape definition to create multiple shapes. Must be initialized using b2DefaultShapeDef(). @ingroup shape

Fields

userData: *mut c_void

Use this to store application specific shape data.

material: b2SurfaceMaterial

The surface material for this shape.

density: f32

The density, usually in kg/m^2. This is not part of the surface material because this is for the interior, which may have other considerations, such as being hollow. For example a wood barrel may be hollow or full of water.

filter: b2Filter

Collision filtering data.

enableCustomFiltering: bool

Enable custom filtering. Only one of the two shapes needs to enable custom filtering. See b2WorldDef.

isSensor: bool

A sensor shape generates overlap events but never generates a collision response. Sensors do not have continuous collision. Instead, use a ray or shape cast for those scenarios. Sensors still contribute to the body mass if they have non-zero density. @note Sensor events are disabled by default. @see enableSensorEvents

enableSensorEvents: bool

Enable sensor events for this shape. This applies to sensors and non-sensors. False by default, even for sensors.

enableContactEvents: bool

Enable contact events for this shape. Only applies to kinematic and dynamic bodies. Ignored for sensors. False by default.

enableHitEvents: bool

Enable hit events for this shape. Only applies to kinematic and dynamic bodies. Ignored for sensors. False by default.

enablePreSolveEvents: bool

Enable pre-solve contact events for this shape. Only applies to dynamic bodies. These are expensive and must be carefully handled due to multithreading. Ignored for sensors.

invokeContactCreation: bool

When shapes are created they will scan the environment for collision the next time step. This can significantly slow down static body creation when there are many static shapes. This is flag is ignored for dynamic and kinematic shapes which always invoke contact creation.

updateBodyMass: bool

Should the body update the mass properties when this shape is created. Default is true. Warning: if this is true, you MUST call b2Body_ApplyMassFromShapes before simulating the world.

internalValue: c_int

Used internally to detect a valid definition. DO NOT SET.
