    Hey guys. I’ve been using AE for a while now and I consider myself an advanced beginner.

    https://youtu.be/vQxD8OOjh-I?t=343

    So I watched this video on youtube and in the video I saw they had restricted Red’s movements so that he couldn’t go underground. I was hoping you guys could help me by telling me how it is done.

    Thanks in advance.

    One way to do it is to set an if/else expression in the position.

    Create a circle, create a null, link the circle to the null…

    add this to the circle’s position property:

    a=transform.position[1];
    [transform.position[0],(a <0?a:0)]
