Actor checks for avaliable space

I have a "controller" in my game that takes care of spawning actors in a random location in the scene. I wanted to know if there is a way to have an actor check to make sure it doesn't overlap another actor, before it spawns?

Currently I just have my timer that spawns the actor every 1 sec, in a random x and y location, using the random expression.

    An easy work around is to spawn the actor and then evaluate if it's overlapping something. For example, in your spawned actor create a rule that states:

    When actor overlaps or collides with YourActor

    • Change Attribute self.Position.X to random(x,y)
    • Change Attribute self.Position.Y to random(x,y)

    You would then evaluate again and again until the rule doesn't trigger. Then you know that you're not overlapping another spawned actor.

    Ok thank you that did work. Only thing now is when it does spawn on another actor, it changes locations but kind of flashes (like a glitch), then moves both actors.

    I was actually just watching video I just found by @tshirtbooth. It's exactly what I am trying to accomplish but one of the steps seems very time consuming lol. He suggested making a table that had all the spawn points I want. That's alot os points to add to the table. :s Im hoping that since the video is 3 yrs old it has a little bit faster way lol

    Spawn an invisible utility actor that seeks out the position, when located it spawns the main actor into a 'safe' location - the utility actor is set so that it does not collide with (so will not move) the main actor.

    Utility actor . . . .

    When actor overlaps or collides with the main actor then do @Braydon_SFX's code
    Otherwise spawn main actor and destroy (itself).
