Hey Guys.
I am trying to create a vertical parallax background made out of 4 different 768 x 1024 backgrounds. I manage to make that. But each time a new background reappears on screen there is a small offset in the continuity and you can see the black background. I made a sample code so you can see what i am talking about so maybe you can help me.
If you can see in the code below the background will start to scroll down when the first background is off the screen with a new color background comes down. The thing is that there is a small offset and you can see the black background I want each color to be joint exactly at the bottom and the end so there is no offset.
Also is there a way to choose in a random way which color background will appear next on screen. Right now they appear on a certain order is it posible to do this in a random way
Any help will be appreciated thanks a lot.
