Hello, all! Lots of people (especially New Scratchers) need help with a scrolling game. This will teach people how to make a simple scrolling game with velocity.

First go to the data tab, create a variable and call it “ScrollX”.

(ScrollX)

Now put this into the scripts section on the character sprite:

when green flag clicked
set [ScrollX v] to [0]

When you do scrolling, you want to make it so when you press an arrow key the terrain goes backwards and looks like the character is moving. This is what you put under the set ScrollX to 0:

forever
    
if <key [left arrow v] pressed?> then
change [ScrollX v] by (3)
end
if <key [right arrow v] pressed?> then
change [ScrollX v] by (-3)

end

Right now, it won't do anything because we have to assign the variable to the terrain. First, create a level sprite with one color on top and another color below it. Put this script in it:

when green flag clicked
set y to (0)
forever
    
set x to ((ScrollX) + ((480) * (0)))
end

Now click the green flag. It works! When you press the arrow keys, the character (technically the ground) it moving! We need the character to jump now. We will be using Velocity. Create a variable called YVel.

(YVel)

Put this script into the character:

when green flag clicked
go to front
go to x: (0) y: (0)
set [YVel v] to [0]
forever
change y by (YVel)
    
if <touching color [#000]?> then
set [YVel v] to [0]
end
if <not <touching color [#000]?>> then
change [YVel v] by (-1)
end
if <<touching color [#000]?> and <key [up arrow v] pressed?>> then
change [YVel v] by (10)
end
end

If you press the up arrow, you now jump!



That concludes this tutorial. You can add whatever you want to the game and make it your own! Happy Scratching!

This is a great idea! Maybe try making one for Scroll Y?

I like your tutorial.
It is very simple and concise. Thanks to scratchblocks.
I used to go to the wiki: http://wiki.scratch.mit.edu/wiki/Scrolling_game

Oh yeah! I forgot to put that in!

I can't figure out how to make it not disappear on the edges…

Perhaps make a section on how to create a bounding box for the character for advanced Detection?
Also, there is also a wiki tutorial.

What do you mean “One color on top and one on the bottom?”

THANKS!!!!

FNAF is still allowed on Scratch.
Direct emulations and games with the jumpscares are not allowed!

I don't really make Scratch projects anymore. I've moved onto Unity and Java.
Now, if only I could figure out how to program in C#…

Also, I play Phantasy Star Online 2 on the Japanese servers! I'm Rock Dasher on Ship 2; I'm a Bouncer/Techer.

My last siggy was reported, I tried getting it back, but it was eaten by an evil kumquat.
