Stop fast bullets from flying straight through small enemies

A very fast shot can be on one side of a small enemy in one frame and on the other side in the next, so it never counts as touching. This entry shows how to check the whole path of the shot each frame and how to know where along it the hit happened.

Why this works

Movement happens between two pictures, but the game only looks at the pictures. A fast shot can skip over a small body without ever standing on it. Checking the whole stretch it travelled, not just where it landed, closes the gap.

When not to use it

Skip it when shots are slow or targets are large, since the extra check changes nothing there. For very many bullets at once, such as a bullet storm, a cheap check of the end point with fatter targets may be enough.
