Methods
cacheRect ()
→ Rect
Update, cache and return the bounding box of a shape based on the body it's attached to.
collide ({required Shape a , required Shape b → ContactPointSet
Return contact information about two shapes.
destroy ()
→ void
Destroy a shape.
getArea ()
→ double
Get the calculated area of this shape.
getBody ()
→ Body
The cpBody this shape is connected to.
getCenterOfGravity ()
→ Vector2
Get the centroid of this shape.
getCollisionType ()
→ int
Set the collision type of this shape.
getData <T > ()
→ T?
Get the user data pointer associated with this pair of colliding objects.
getDensity ()
→ double
Get the density of the shape if you are having Chipmunk calculate mass properties for you.
getElasticity ()
→ double
Get the elasticity of this shape.
getFilter ()
→ ShapeFilter
Get the collision filtering parameters of this shape.
getFriction ()
→ double
Get the friction of this shape.
getMass ()
→ double
Get the mass of the shape if you are having Chipmunk calculate mass properties for you.
getMoment ()
→ double
Get the calculated moment of inertia for this shape.
getRect ()
→ Rect
Get the bounding box that contains the shape given it's current position and angle.
getSensor ()
→ bool
Get if the shape is set to be a sensor or not.
getSpace ()
→ Space
The cpSpace this body is added to.
getSurfaceVelocity ()
→ Vector2
Get the surface velocity of this shape.
noSuchMethod (Invocation invocation → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
pointQuery ({required Vector2 point → (double PointQueryInfo
Perform a nearest point query. It finds the closest point on the surface of shape to a specific point.
The value returned is the distance between the points. A negative distance means the point is inside the shape.
removeData ()
→ void
If you need to perform any cleanup for this data, you must do it yourself, in the separate callback for instance.
segmentQuery ({required Vector2 a , required Vector2 b , required double radius → (bool SegmentQueryInfo
Perform a segment query against a shape. @c info must be a pointer to a valid cpSegmentQueryInfo structure.
setBody (Body body → void
Set the cpBody this shape is connected to.
Can only be used if the shape is not currently added to a space.
setCollisionType (int collisionType → void
Set the collision type of this shape.
setData <T > (T data → void
Set a user data point associated with this pair of colliding objects.
setDensity (double density → void
Set the density of this shape to have Chipmunk calculate mass properties for you.
setElasticity (double elasticity → void
Set the elasticity of this shape.
setFilter (ShapeFilter filter → void
Set the collision filtering parameters of this shape.
setFriction (double friction → void
Set the friction of this shape.
setMass (double mass → void
Set the mass of this shape to have Chipmunk calculate mass properties for you.
setSensor (bool sensor → void
Set if the shape is a sensor or not.
setSurfaceVelocity (Vector2 surfaceVelocity → void
Set the surface velocity of this shape.
toString ()
→ String
A string representation of this object.
inherited
update (Matrix4 transform → Rect
Update, cache and return the bounding box of a shape with an explicit transformation.
