R0J0hound - Thanks Ill check that out tonight.
Ribis - Yes, as stated in the OP the behavior does work well, but sliding against angled walls seems like it should be part of the behavior similar to how the platform movement deals with slopes without extra code. The Platform Behavior has received many improvements to increase it's usability but 8 Direction hasn't gotten much attention.
yes, I understand and you are right, make it simple if the behavior has more implementation, but for some request is better if you made your own script for make your own gameplay... but a wall sliding can be an important integrate.
R0J0hound I locked your script (and don't just this)... and they are like an art... did you study math?
