3d Character Pawn has the following settings changed:
Use Controller Rotation Yaw - Disabled
Use Controller Desired Rotation - Enabled
Orient Rotation To Movement - Enabled
Behavior tree, confirmed that Rotate to face BB Entry is causing the problem.
Move to works with Rotate disabled.
BTService blueprint gets random vector location.
Can move to location.
However, cannot turn to face direction.
Orient Rotation To Movement - Enabled
Should be Disabled
If anyone could explain to me why this causes the character to freeze up, please let me know.
no, this is not the reason…im currently getting this same issue and I have that disabled.
Just stumbled upon this today. The reason it works like that is that what UBTTask_RotateToFaceBBEntry actually does is it sets Focal Point for the controlled AI. And for characters to rotate to Focal Points it’s necessary to set Use Controller Desired Rotation to True, as in this case the desired rotation is the rotation required to look at Focal Point. Orient Rotation To Movement overrides this behavior, so it has to be disabled.
The issue @zeth_foxster was having must have been caused by something else, unfortunately there is a number of ways to break AI rotation.
