public PhysicsShapeGroup2D(int shapeCapacity = 1, int vertexCapacity = 8)

Parameters

shapeCapacity

int

The initial capacity of the PhysicsShape2D list used to contain the shapes.

vertexCapacity

int

The initial capacity of the vertices list used to contain the shape geometry.

Remarks

Both the shapeCapacity and vertexCapacity should be set high enough so that new allocations are not required and therefore no garbage collection work is produced.
