Monster truck game issue

[Ebred]

Hi All,
I am hoping one of you can help a noob

I am just testing a monster truck "game" and I am having a problem with flicker when the truck gets repositioned once 1.5 times the width of the frame is reached. I think it has something to do with the joints that hold the wheels on the truck.. on the first reposition of the truck, i set the truck Z-order to go forward so that you can see there is slack/movement at the joints, pinning the tires to the truck.

Any help would be greatly appreciated.
I have attached the MFA for what i have. ok its 2.6 MB apparently thats too large to upload.

Heres a link

Is the purpose of re positioning to make this an endless driver type of game?

I have found the best results in endless type of games to scroll the background but I have never tried it with the ground object.
I will play around a bit more and see if I can figure out how to reduce that flicker.
Wonder if the calculations on the frame size are slowish.

The file above is also missing the ground graphic -- It might be a good advice to import that in rather then use an active picture.

Woo hoo. I finally got it. Here's what I did:
I deleted both joint objects and the physics engine. Then added the physics engine and joint back. Duplicated the joint for the front wheel

I then changed the hotspot and action point to right center

I also added an event: when truck collided with background - stop

That did it. No more flicker.

Thanks Jeff appreciate your advice!!!

Thanks to uppernate too. You've been super nice and helpful!!

Ok now to make some good stuff

Thanks for the update and I like the smoke effect you did in your truck!
