<p>Reply to <a href="/wiki/Thread:Talk:Talon/source/Wall_avoidance" title="Thread:Talk:Talon/source/Wall avoidance">Wall avoidance</a></p> <p><b>New page</b></p><div>How does this look? It will hit walls when it doesn't have enough time to turn, but it doesn't stick on them. If there were only eight bytes to spare I could make it slow down when it had to make a wide turn, which would greatly reduce the number of wall hits.<br /> <br /> <br /> <br />
