ADOBE DIRECTOR 11.0 115 Scripting Dictionary registerCollisionCallback() Usage world .registerCollisionCallback( #collisionCallback,) Description This function registers the callback function that is to be called to report the collisions. There can be only one collision callback handler for the physics scene. The information about the collisions is passed to this function in a Collision Report list, which contains the following information: Parameters Parameter CollisionCallback Script reference Description Required. This specifies the name of the collision callback handler. Optional. This is a behavior or parent script instance. If this parameter is not provided, it is assumed that the callback function is defined in a movie script. Structure of a Collision Report: . ObjectA ObjectB list (vector) list ( vector) Object A involved in collision Object B involved in collision The contact points between the object A and object B The contact normals for each of the above points. Note: Inside the collision callback handler, if there is any script that causes runtime errors (such as property not found), the error messages are not displayed, and the handler execution is aborted at the point of error. All the subsequent statements are not executed. Avoid modifications to the 3D scene within the collision callback handler, like resetworld(), deleteModel(), deleterigidBody(),etc. Example --Lingo Syntax member("PhysicsWorld").registercollisionCallback(#collisioncallback) --Movie Script On collisionCallback collisionReport CollisionA = collisionReport[1] R1 = CollisionA.objectA R2 = CollisionA.objectB lstPoints = CollisionA.contactPoints lstNormals = CollisionA.contactNormals end //JavaScript Syntax member("PhysicsWorld").registerCallback(symbol("collisioncallback")); //Movie Script function collisionCallback(collisionreport) { var CollisionA = collisionReport(0); var R1 = CollisionA.objectA; var R2 = CollisionA.objectB; var lstPoints = CollisionA.contactPoints; var lstNormals = CollisionA.contactNormals; }
