Moving other actors on the scene

This maybe a simple thing to do but I can't seem to find an answer or determine how to do it. What I would like to do is spawn a new actor (which I have done) and then from another actor (button) have that rotate the first actor 90 degrees. What I can't seem to determine is how to access a spawned actor in a scene like in js executing a getElementByID type of function. Is there a way to do this or do I need to find another way by using scene flags and reacting to that?

    Are you looking for something like this where you use one actor to control another?

    These controls move an actor around the screen but it would be simple to use the same concept to control an actors rotation.

    @jamie_c's example is probably enough to get this working but just in case...

    The way you do this is by using a global variable, e.g. game.firstActorRotation. In the button actor, you change or constrain the value of game.firstActorRotation and then in the spawned actor, you have a behavior (no rule) that constrains self.Rotation to game.firstActorRotation.

    Thank you for the response - this is what I mentioned as the alternative to making changes directly. Ideally from the example I would like to be able to click on the Right arrow and then in the click event instead of setting the flag I would want to move the Green Square directly to the Right. The issue that I have is that I will have multiple actors on the screen (cards) and depending on what the current card is I wanted to be able to rotate that single card. If there is no direct way then I can set the same type of flag to rotate 90 degrees card x if the card x is the current card - basically 2 tests in the card actor.

    Let me see if I can make you a quick demo...

    If that being the case then for all 13 cards that will eventually be in place I would need a variable for that correct? I would still need to reference the current card flag in the Button to set the correct game variable; however, that should work and may be a little cleaner as the code would reside mostly within the Rotate Button actor itself.

    Okay, this is the general idea. I didn't spend any time on the actual rotation math so it's very rough (the cards just spin) but I think you'll get the idea.

    Thank you for the example seems as though currently then there is no way to directly interact with another actor except through a game attribute correct? I mean I could not just hide another actor without having a variable as a game attribute and having the actor reacting to that change? Just want to make sure I'm not missing something as typically in JavaScript I would have located the element and modified it's property directly.

    Thanks again for the example.
