Project290.Physics.Dynamics.Body.DestroyFixture C# (CSharp) Method

DestroyFixture() public method

Destroy a fixture. This removes the fixture from the broad-phase and destroys all contacts associated with this fixture. This will automatically adjust the mass of the body if the body is dynamic and the fixture has positive density. All fixtures attached to a body are implicitly destroyed when the body is destroyed. Warning: This function is locked during callbacks.

fixture Fixture The fixture to be removed.
