    Default Collision with drawn lines?

    Basically, I want to achieve a way to for-see and calculate collision with lines that players draw. Like in line rider without all the fancy pants physics. The type of collision I'll be achieving will be from an isometric view. Can someone help me with this?

    Store the line details and compute object movements a step ahead in time to see if they collide?

    I thought of this but doing it wouldn't really be that easy. I can't think of an efficient way of doing it essentially.

    For a small number of objects, even a brute force solution is reasonable.

    Otherwise you might wish to consider looking into spactial partitioning algorithms.
