I'm using a library (playcanvas) that exposes a function clone()
that is called recursively for all the nodes in a hierarchy.
If I monkey patch the function to execute some additional code, this will be executed multiple times.
Instead, I need to execute my code at the end of the whole recursive calls, but I can't find a way to do it.
pc.Entity.prototype.clone = function() {
... some code
// then for each child it calls itself
}
If I try this way I get "my stuff" executed multiple times.
pc.Entity.prototype.cloneOriginal = pc.Entity.prototype.clone;
pc.Entity.prototype.clone = function() {
var c = this.cloneOriginal();
// do my stuff
return c;
}
I need to "override" the clone
method so that after all its recursive calls, I can execute my code.
You can achieve that by temporarily restoring the original function before launching it. And when it is finished, you set your trap again, and perform your post processing:
