I have created som simple characters that move around in a maze using the AI_move_to function. This works great, except that the character change their direction in 45 degree steps. How do I change this? The Character Movement menu has a rotation rate option, but no matter what values I use it moves in 45 degree steps.
In addition to adjusting the rate of rotation, you need to enable Orient Rotation to Movement, which is directly below Rotation Rate in the Character Movement Defaults. Then, under Pawn in Defaults, disable Use Controller Rotation Yaw. You should see your pawn rotate more smoothly. You can now adjust the Rotation Rate for Yaw and see a difference.
Hope that helps!
