You were telling how to do it as well as doing it right then!

I can't seem to figure out how to set the background of the whole world to an image and not just the first viewpoint and then stretch it (on the limited scrolling). Like how it was done in your old Scrolling SuperWorld.

@Paul12345 Please start a discussion thread on the issue.

Is there a way to make some actors move quicker than the player to make a perspective effect? Like change the scrolling speed of some trees to make them move slower to make them feel closer?

@Kizetsu, start a discussion thread on your issue. Provide your attempted codes (complete classes) and an error trace from that particular code. Help can then be provided.

When you talk about the object class, do I create a new class, or put it in the world/actor class?

I figured out the object class thing, but how do I get it to scroll horizontally instead of vertically?

@JooshK, just use a zero value for the vertical offset when calling the 'scroll(int, int)' method. For example: scroll(1, 0);
