Destroy Physics Joint

I modified the Physics plugin to add an action that destroys all Physics Joints. All is well until I get this error in the console, then it can't register any more joints as well as other weird behaviors.

I added this code to edittime.js

<font face="Courier New, Courier, mono">AddAction(901, af_none, "Break joints", "Joints", "Break all {my} joints", "Break all physics joints on this object.", "destroyMyJoints");</font>

And this code to runtime.js

<font face="Courier New, Courier, mono">acts.destroyMyJoints = function () {

     this.destroyMyJoints();

};</font>

Here is the capx for the game the error occurred in.

The frisbee will "stick" to a pole when it hits it and spins around it until you either right-click or press space bar. You can control the frisbee while it's on a pole in any of three ways:

• Click on the frisbee to push it.
• Use the arrow keys to move it.
• Hold down the left mouse button anywhere but the frisbee. A white ball will appear. Move the mouse to hit the frisbee with the ball. When you let go the ball will disappear.

You're probably not breaking other instance's references to that object's joints. I'll see if I can add that action officially anyway so you don't need to hack the behavior yourself.

Hey Ashley, would be possible to incorporate tags to joints when you create them to allow to selectively destroy them later?

Yeah, that would allow finer control... I'll see what I can do...

Thank you, Ashely

Sorry to necropost this suuuuuuuper old topoic . Ashley Do you think it's feasible to be able add tagging joints so we can destroy specific ones like mentioned above?

If not I can use the workaround mentioned in the physics manual page. Thanks!

[I saw this post when I was searching to see if this was possible. Which is why I necro'd rather than posting a new one]
