smoothing?

[cassius]

The scene in my game has a lot of flicker particularly when I move the mouse.

Does anyone know how I can apply some linear smoothing? Or whatever else will work.

[Marleys Ghost]

Can you define "flicker" Cass?

[cassius]

its a very slight flicker of character (third person) when I move it.

[Marleys Ghost]

Can you post a video?

[cassius]

No I am unable to do that.

aggror mentioned smoothing but didn't elaborate on it

[Marleys Ghost]

Demo .exe?

[AggrorJorn]

I don't think smoothing is the answer here. It looks like it is something completely different. Can you export the project as an exe?

[cassius]

I was wrong about mouse movement causing this flickering. It only happens with keyboard movement. ie w.a.s.d.The code is largely aggrors third person tutorial code exept I have replaced the cylinder with my character. The only other change is in the value of maxcamoffset which I changed to -1.2 to bring character nearer to camera.

Can you post your routine? and more info on how you are setting up the parenting with the pivot?

Could you also post an exe?

 

If you uncomment the badguy creation and everything else that has nothing to do with the player, do you get the same result?

[cassius]

I found that if I alter the niaxcamoffset value then alter the mincamoffset by a similar amount it works smoothly but strafe causes flutter of character. But I won't need that feature as I have no animation for sidestepping character.Your code works fine with the cylinder. Have you tried it with a character?Thanks for reply.I will try what you suggest.

[cassius]

I thought what I said in my previouse thread (above) had solved the problem but it did not. However it seems that parenting to the player was causing the flutter.I removed parenting and it now works perfectly.
