I cant figure out why the character controller on my enemy AI is moving super slow. I put a debug statement in the chase function to see what was happening. The controller is moving at (0.0,0.0,-0.1), even though the movementDirection vector is < or > 0 for x,y & z. It changes based on my postion, so the character at least turns to face me. When I wrote this in js it worked fine. In c# its giving me all kinds of trouble. The code is a hodge podge of my code and some from a tutorial I was following. I have spent a few hours researching and trying different things. Thanks in advance for the help.
