Work out which platforms an enemy can jump to before it tries

Your chasing enemy leaps at ledges it can never reach, or ignores ones it easily could. Here is how to decide from the jump itself whether a gap is crossable, why a higher ledge is not simply a shorter jump, and how to leave room for error.

Why this works

A jump follows a fixed curve, so whether a gap can be crossed is a matter of arithmetic, not luck. Asking where the curve comes back down to the ledge's height answers it before the jump, and planning a little under the limit absorbs small errors.

When not to use it

Skip it when your characters can steer in mid-air, double jump or glide: the fixed curve no longer holds and the answer will be wrong. Test those moves by simulating the jump frame by frame, or place the jump points by hand.
