How to add background to your game
Step 1, make a new layer
Step 2, Select it and adjust the parralax
I recommend 10% x 10%
100%x100% is when a game scroll every object from that layer also scroll
0%x0% is when every object from that layer always stays at the same place on the screen
Step 3, Add a object to a Background layer
I use tiled background when I want to insead of screeching make object tile when I expand it
Else, I use a Basic Sprite
Part 4, Import your background
First, swipe your TiledBackground\Sprite to the Layout
Then select a non-Background layer and in properties uncheck a checkbox with text
TRANSPRENT
Select your background by tapping it then go to Animation and tap Edit
Then import a image by tapping the open button
After that exit an image editor and adjust your background
AFTER THAT YOU ARE DONE! NOW YOU HAVE A BACKGROUND IN YOUR GAME
