Pushing Actor "skidding" and "jiggly" when not pushed

romma

Hey Guys,

I have an actor (block) that my player pushes around, It has around 600 friction and 200 drag to add more "weight" (heavyness) Problem is when Im not touching the "block" it moves up, down, to the sides, no pattern likes it's skidding on the ground. I have a rule that states "when not colliding" to set LinearVel X and Y to 0, but doesn't help.

Here ya go man;

Its a very trimmed down version of a complex set of code I'm using for a new game. You'll be able to see the exact settings I use to not have shaking

romma

That helped a lot thanks! But there is still some wiggle when I push and stop pushing, and it's not friction wiggle, its like a shake

Yeh i found this and the shaking is annoying. I did the following;

When Block being pushed = false
-- Timer
-- After 0.1 Seconds
----Constrain self.linear.velocityX to 0

This will eliminate the shake, just be careful with constrains as too many 'can' hurt FPS

romma

Beefy,

I have that same concept but the linear.velocity not as a constrain but as a change atrib. Any differences in this case? Yes, I avoid constains at all causes.

beefy_clyro

I think with a change attribute it will start to shake again. I would just go with the constrain, it won't hurt performance very much, you can get quite a few in before you notice any drops

romma

This is odd, it got worse with the constrains. It shakes constantly now when I stop pushing it.

beefy_clyro

Shouldn't do!! We'd have to see your rules and a video of the block in action

romma

Here's the rule.

When I push and let it go it starts shaking 1 pixel in all direction.

I use similar rules but literally have it just constraining on linear velocity X, get rid of the other 2, its probably conflicting.

romma

Doesn't work. It still has some "jiggy with it"

romma

Reload the link above, I cleaned the rule. Still no work.

beefy_clyro

I would still have it in a separate rule;

e.g.

when self.pushed = 0
constrain velocity.x to 0

Making you a demo now

romma

Cool thanks, would be nice to see it not shake on your side!

romma

Very nice of you. I will study this and find my solution. Thanks!

No worries @romma, I best get some sleep as its late here now and i have physio early tomorrow. Hope that helps and you can track down your problem.
