Why is this framerate dependent?

Just asking, since I thought 8direction behavior already has dt.

moving it with this btw

Don’t use dt and it won’t be.

Im sorry I said it wrong, the dt actually fixes it. using only clamp(self.8direction.maxspeed + 1, 0, 250) becomes framerate dependent.

(rate1-rate2)*dt vs rate1 -rate2*dt you can see how even though they both use dt somewhere, only the first one scales uniformly with dt. Perhaps this is the problem?

Oh. Sorry, I didn’t read it well the first time. It wouldn’t be a bug and yes the way you did it does fix the frame rate dependence.

With maxspeed=maxspeed+1 in 1 second at 60fps the maxspeed would increase by 60. At 120fps it would increase by 120 in one second.

By changing it to maxspeed=maxspeed+60*dt it would increase by 60 in one second no matter the frame rate.

If the behavior had a rate of change for the max speed it could handle it for you, but it’s a bit unrealistic to handle all cases, so doing what you’re doing is fine.

Ok thank you. I closed the bug report then.
