How can i make colliders on specific parts of a full circle ?
Say i want an actor to go through the a circle hoop but collides with the top and down part of the hoop , How can I do this ?

    You will have to use invisible actors placed or constrained around the circle to create "walls"

    Also please read through the new Rule/Guidelines Sticky for Reasons Why we prefer you do not use thread titles like "Help!!!!" or "Urgent!!!!!" etc…

    Thanks

    Good Luck

    Make the Loop, and an invisible circle actor in the center.
    Make game attribute, game.Centered = Boollean.
    In your main actor have a rule like this.
    If Overlaps or Collide with: Loop and invisible circle.
    Change attribute game.centered to true
    Otherwise false.

    Another rule
    If Game.centered = True
    Nothing
    Otherwise
    Collide with Loop.

    _Cheers.

    Make a circle sprite then change the collision shape to circle in the physics part of actor.

    I'm not that good , by circle sprite , you mean any circle model ?

    by circle sprite they mean a circle image, or set of images for a animation.

    Hi Thani ... from your post I was reading your issue a little differently than some (more like tenrdrmer I think).

    Are you looking for the collision to happen inside the loop? Like say a plane flies thru a loop but hits a part as it exits?

    Let us know if so and will be able to provide a solution to that. If not then I have it wrong and yes you can select a circle as the collision shape but the collision will happen on the first point of contact on the outside of that circle.

    This is what I mean.
    Plane goes though the hoop , nothing happens . But it gets destroyed when it collides with the down or top part of the hoop .
    So basically whats happening is ,
    If plane goes through the hoop ( not touching the top or down part of the hoop ) the plane doesn't get destroyed
    but it gets destroyed when it collides with the top and down part of the hoop .

    So is there a way to create actor to specifically cover a certain part of the hoop ?

    that's what I thought.

    Couple of issues as I see it:

    1. Your hoops will need to be cut in two in your graphics program so one can exist behind the plane actor and one in front. You will need to place them together to look seemless and co-ordinate their movements in synch

    2. You will need a few invisible actors to be the actual colliders. They should be placed around your circle and constrained to the x and y of your circle offset by + or - values.

    This may sound hard but it actually isn't really. First thing I would tackle is getting you two loop halfs to fit together and move as one.

    Let me know if you need more on this.
