PhysicsEngineRemoveGeometryProcessContactHandler Method

Note: This API is now obsolete.

Remove a contact handler delegate from a geom.

Namespace: Demo3D.Visuals
Assembly: Demo3D.Core (in Demo3D.Core.dll) Version: 19.00.00
Syntax
C#
Copy
[ObsoleteAttribute("RemoveGeometryProcessContactHandler is deprecated, please use RemoveGeometryProcessCollisionHandler instead.", 
	false)]
public void RemoveGeometryProcessContactHandler(
	PhysicsGeometry geometry,
	ProcessContactHandler handler
)

Parameters

geometry  PhysicsGeometry

[Missing <param name="geometry"/> documentation for "M:Demo3D.Visuals.PhysicsEngine.RemoveGeometryProcessContactHandler(Demo3D.Visuals.PhysicsGeometry,Demo3D.Visuals.ProcessContactHandler)"]

handler  ProcessContactHandler

[Missing <param name="handler"/> documentation for "M:Demo3D.Visuals.PhysicsEngine.RemoveGeometryProcessContactHandler(Demo3D.Visuals.PhysicsGeometry,Demo3D.Visuals.ProcessContactHandler)"]

Remarks
Using geometry contact handlers is deprecated. Use geometry collision handlers instead.
