Jerky movement infinite x-tile

[d-soldier]

SEE ATTATCHED IMAGE:

I've noticed a jerky motion in my current project on my "ground" image while is infinately x-tiled. I've adjusted various settings, and even exported the game to verify that it jerks during compiled gameplay as well. The actor's DRAW ACTOR SCRIPT is:
"xvelocity = -2;"
... every few seconds it jerks back and forth a couple pixels... My framerate is remains between 29/30, and there is no apparent cause, as it happens during various intervals of the moving actor (no specific point during the scrolling) Is there a better way to do this?

I think you need to change the x value, not xvelocity.

I just checked through the variables/functions sections and didnt see anything relating to xvalue... and the script editor doesn't seem to accecpt it as a command either.???

I mean the x position:

Code: Select all

x -= 2;

But, looking your code again, I see you don't change the xvelocity value every frame. So, you can set the xvelocity outside of the 'Draw Actor' event.

x -= 2;

alot simpler than you think.
(funny name for setting an x value right? )
