I too have a quick question about 8dir (and Custom movement), so I hope no one minds me asking my own question. : D

EDIT: there's a link there. I hate how this forum now seems to cut image sizes so it can fit within the forum template. Frustrating!
I'm using Custom Movement and 8 directions to make enemies that move from side to side and up-and-down. When they hit an object with the attribute 'Bouncer,' I want them to reverse their movement angle by 180 (so if an enemy is traveling right, it turns left; and if an enemy is going up, it turns down). However, none of the various solutions I've tried arrive at that outcome; the enemy hits the bouncer attribute object and then turns left invariably.
