To copy all code easily, go to this project play.creaticode.com/projects/679240dfee3a4781a5afde57

Today we are making a simple platformer game! Start by making the character sprite, you can make it a square, triangle, human, squirrel, alien, anything. Set your characters size to anything, for this, I’m going with 85. Use this code to make it!

when green flag clicked
    set size to (100) %

Nice!

Now, lets add a simple gravity system. We’re going to have to add the “LevelGround” sprite, lets do it!

After creating that sprite, you can use this code inside of “LevelGround” to make it go to the middle, make sure your character’s sprite is at the bottom of the boundary box for creating sprites, its fine for it to be outwards

when green flag clicked
    go to center

Now, for the player, copy this script for basic gravity!

when green flag clicked
    set [Gravity v] to [0]
    forever
        change [Gravity v] by (-0.2)
        if <key [space v] pressed?> then
            set [Gravity v] to [6]
            wait until <<not <key [space v] pressed?>> and <touching (LevelGround v)?>>
        endif
    end
end

Oh, no! Our players gravity is going down super fast! Let’s fix that!

First, add a variable called: “Cooldown”, make this simple line:

when green flag clicked
    set [Cooldown v] to [N]

Awesome! Now, lets edit our script that was for gravity.

when green flag clicked
    set [Gravity v] to [0]
    forever
        wait (1) [milliseconds v]
        change [Gravity v] by (-0.25621)
        if <<(Cooldown) = [N]> and <key [space v] pressed?>> then
            set [Cooldown v] to [Y]
            set [Gravity v] to [6]
            change y by (2)
            repeat until <<touching (LevelGround v)?> or <(Gravity) = [0]>>
                set [Cooldown v] to [N]
                change [Gravity v] by (-0.25621)
                set [Cooldown v] to [Y]
            end
            set [Cooldown v] to [N]
        endif
        if <touching (LevelGround v)?> then
            set [Gravity v] to [0]
        endif
    end
end

Awesome! Now, we have to make movement.

Make these 2 when pressing a / d blocks!

when [a v] key pressed
    repeat until <not <key [a v] pressed?>>
        change x by (-4)
    end
end

And

when [d v] key pressed
    repeat until <not <key [d v] pressed?>>
        change x by (4)
    end
end

Awesome! Now, you can make your own custom levels, you should add a second sprite for the outline so that if you collide with it, you don’t go upwards, hope this helps!

Thank you for contributing to the community.

I assume you got these pseudocode using the right-click menu’s “copy pseudocode” option, right?

FYI, you can also use the “Export PNG Image” option above it, so that you get high quality block images. Of course, you can also use screen capture. Usually a block image is easier to read compared to the pseudocode for beginners.
