Actor jittering left and right when stopped.

FjantInc

Alright, since I can't seem to get my jumping right I decided to go back and redo it with a new actor. I didn't get far until I ran into problems. After going left / right with my actor and coming to a stop, the actor don't really stop, but "jitters" around... a few pixels to the left and right... I've tried both with Accelerate and Change velocity with the same results. A similar thing happened with my old actor, which started jitter up and down when standing on some platforms. That thing started with 0.9.

Anyone knows what to do?

Try this: under the physics of the actor, try changing the restitution to a lower number, that fixes the "Bounciness" of the actor

Also, if you have a platform, go in and change it's restitution as well as it's motion.

Under Motion: Check only "fixed rotation" for the ground actor. (uncheck: Moveable)

That should fix it!

Alright, I'll give it a shot. I thought the restitution was only for when the actor collided with a platform (and bounced)... My actor doesn't collide with anything but jitters nonetheless. However, I'll give it a go when I'm on my mac. Thanks!

Nope, it didn't help. I've tried several values as restitution, but with the same result.
I've uploaded the gameproject file, so if anyone could take a look (or just see if it happens them aswell) I'd me more than happy!

Hi undersky, I've changed a few things, including adding a maximum speed. This needs to be higher than the speed shown in the Change Velocity Behaviour, it would seem. So what I've done:

Under Motion, in the attributes section, made Max Speed to 350.
Checked Apply Maximum Speed

Under Physics, Density 100, Friction 20 and Drag 30.

You might need to tweak this numbers more to what you're after, but at least the jitters have gone (doctor). ;-)

Thanks a lot! It seems like it worked. Have a christmas present for being nice and not naughty http://www.highyieldsavingsaccount.com/wp-content/uploads/2010/11/xmas-present.jpg

I think I'm starting to see why my changes don't really happen... It seems like I have to drag out a new actor of mine everytime I've made a change and want to preview it? Can anyone confirm that it's so and that it's just not some bug? Because I edited another actor that could jump... I deleted all of the rules for him, and I could still control him like nothing's ever happened.
