How do I pass an object/sprite through a function parameter?

You could have an instance variable / boolean that you select by in the funciton. Before calling the function set the instance variable for the object(s), then pick by that instead.

When you call the function you pick objects with the boolean set to enabled, for example, instead of UID.

tunepunk Cool, thanks heaps :) Yeah, I've been using the instance variable method, then picking it by it's name - it's not too bad of a workaround. Would be cool, if you could just pass the specific object in a param without it tho.

There's also a thing Called IID. Can be quite useful at times. It's kind of like UID.

I don't know why the object properties is not showing this number, but if you check the debugger you can see that every object has an IID (instance ID) as well.

You can then use the System expression - Pick nth object. Then you can pick the specific object of that object type by IID instead.

So send the the object IID with the funciton then "pick nth object".

Maybe that could work as well?
