How do I check sprite overlap with itself for each sprite

  • I've been trying to figure this out for a while now...

    I have a layout full of instances of the same sprite.

    I'd like to go through each instance and check if it overlaps with another instance of itself.

    Then do a set of actions with pick instance 0 / instance 1.

    My problem is:

    • If I limit the SOL to make sure i've checked each instance; the subsequent overlap check won't work because SOL will contain only one object.
    • If I use overlap for all; pick instance 0 and pick instance 1 will not work except for the first two instances.

    How do I combine these two? Or am i going about this the wrong way?

    Thanks!

  • Create a family with this sprite and use it to refer to another instance of the sprite in the same event.

    E.g.:

    For each Sprite

    ...Sprite overlapping SpriteFamily

    ........SpriteFamily Set Invisible

    ........Sprite Set Visible

  • dop2000 holy **** it works!

    Also do you think there is any way to solve this without using families?

    I'm just asking because the solution seems like a workaround to the problem and if there is any other way it could work I'd like to know; to better understand this stuff.

    Thanks again!

  • Yes, it's a workaround, but it's a legit workaround

    I think I saw it in one of the official tutorials.

    I guess you can do the same with a function. If sprites are overlapping, call a function, pass sprite UID as a parameter. Inside the function pick all sprites with UID<>param(0), check overlapping again and... not sure what's next. I remember doing something like this, but I don't remember how

    The method with the family is much easier.

  • I image you'd have the same problem with functions as the first problem I had. You can't get the id of the 2nd instance if you stop using families (when checking all instances).

    Anyways thanks for the help!

    Also, your game looks really nice!

  • No worries!
