God dammit, problem after problem, havin' a bad week.
right, basically, this is probably poop easy to you lot, but i've never made a sidescrolly game thing, so, how do i keep the plane level with the scrolling camera, without having it being pushed back? Also, don't just say set the speed to the same of the camera, doesn't work because it's never perfect... i always get an annoying jittery movement because the cam moves forward then the player moves forward...

Have you tried making the camera follow the actor?

no no, i don't want that, that would mean when you moved forwards so would the camera, and you could move backwards in the level. Have you ever played a traditional side scroller?

You mean like the original Super Mario Bros? Couldn't understand exactly what you need, but here goes anyway.
Attribute:
Old X: number (hidden)

Always
-If [Old X] > [X of camera]
Move camera to x:[Old X] y:[Y of Camera]
-
Set Old X to [X of Camera]

You're setting the camera by changing it's x/y value right? So when that happens, change the x/y of the plane as well.

Yeah, both of you, that's what i was thinking, but you can't change it exactly, x position doesn't handle fractions, just rounds em down, whereas the camera does. So, i just checked when the distance moved becomes 1, then added that on. However, i'm still getting a jittery movement...

Hi, my apologies for opening up an old thread, but I'm having the same jittery issues and I'm wondering if you (ipe 369) could post a more in-depth explanation of how you fixed it.

Maybe a screen shot of the code?

Thanks in advance!

Don't make the camera follow the actor, but make the actor follow the camera. You need a code block to look like this:

Then make a scene block which moves the camera. Like this:
Games: Arrow Mania, Breakout/Outbreak, Water Drop

Another alternative is making the Main Actor affected by gravity. Set the Scenes gravity to left or right with a constant number. Make the camera follow the actor, and it will not be able to go as you say in reverse.
