Subject: badguy/haywire.cpp: Use the x-acceleration to follow the player.
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=1668c3cfe8bca9a396f2a00b857097fa693bc079;p=supertux.git

badguy/haywire.cpp: Use the x-acceleration to follow the player.

This is a lot smoother and generally nicer than the previous (proof of concept)
