Weird bug with Mouse Look Actuator UPBGE 3.0

Game Engine Game Engine Support and Discussion

I have an player controller developed by myself. It’s a script that controls the character movement activating a movement actuator, and the camera movement activating the mouse look actuators.

I have 3 look actuators: Camera, Player and Reverse Player (this one is for specific reasons).

The problem is that if I press W and move the mouse at the same time, if I get my hands off the PC the camera spins forever, a very weird bug.

Yes, the W key sensor are the movement inputs, also connected in the same script.

Probably not related, but there was a similar reported but, except it was for UPBGE 0.2.5.b.
The issue may still also persist in UPBGE 0.3+ versions.

Also, in your mouselook script, are mouse movement values normalized?
If not, that is probably the cause of your issue.

It’s a mouse look actuator. The part of effective turning camera accordingly to mouse is done by a actuator.

I’m trying to make a mouse look script myself to avoid this error, but it’s kinda hard to keep it simple as just to have an always sensor and some properties on the camera to look with.

Could you please share a minimal blend that can reproduce the issue.

I don’t actually know why it happens to reproduce. I tried to make it bug on a new scene but it seems to not have any problems. I was trying to use different scripts, but I ended not using them. I will try to import the player separated from the whole scene to check if it still present errors.

the mouse brick is bugged since release of 3.0, just use a script version, look into resource section.

Actually now I realize what means “normalized”. Indeed it’s a bug that it sets the pixel coordinates to a floating point and some other complex stuff. But the thing is that Only when I’m walking, not always.

When moving with WASD it slides, but stopped the camera turns normally.

have you tried to turn down mouse sensitivity
