Sure, I actually have two blendspaces for start animations. One is used when there’s movement on the forward axis, the other is for strafe starts. The first one is what you’re interested in.
It has variables of angle which ranges from -180 to 180 (the output of calculate direction), and speed which goes from 1 to -1. Forward and backward starts are set at 0 deg, speed is 1 and -1 respectively. Then the 90 degree and 180 degree anims are placed where they should be.
