How to Make a Landscape Generator in Scratch

In this step-by-step tutorial, I will show you how to make a super easy random terrain/landscape in Scratch.With this generator, you can make all kinds of games including: Adventure games,Minecraft related games,random animated adventures and so much more!

Good news! You only need Scratch, a block programming website.This is the link https://scratch.mit.edu/.

One more thing you will also need these files so make sure to download it.

Once you are in Scratch find the “create” button, this is how you make a new project.Then press the costume section.On the bottom left side of the screen there is a cat with a “+” ,you will need to click it and upload a costume.Make sure to choose files and upload the three files.Afterwards,delete the cat costumes.

Congratulations, you finished the first step!

Ok time for programming, make two variables, name one Height and name the other, Slope. Now copy this (See pic 1):

when flag is pressed
 set Height to pick random 2 to 4
 hide
 clear graphic effects
 set slope to 0
 set size to 75

After you copy this down you will have to go to “my blocks” (it’s red) and you need to make a block and name it “Generator” ,make sure it is running without screen refresh (makes it fast). Add the generator block to the pre-existing script.

Now under the larger “Generator” block copy this (See pic 5):

Define - Generator
 go to -216 -157
 repeat 10
  repeat ({height}-1)
    switch costume to “Landscape dirt”
    create clone of myself
    change y by 48
  set rotation style left-right
  if {(slope)=0}
    switch costume to “Landscape grass”
   else
     if {(slope)=1}
       switch costume to “Landscape slope”
       point in direction 90
      else
        switch costume to “Landscape slope”
        point in direction -90
  create clone of myself
  set y to -157
  change x by 48
  if {(slope)=-1}
    change Height by -1
  Height (height)  //explained later ,it is another “my block”//
  if {(slope)=1}
    change Height by 1

Yep another “my block” ,but it’s okay because this will improve the speed of the generator, and is the the last one.In this “my block” name it “Height” ,just like the last one make sure it is running without screen refresh, one difference though because there is an input for a number or text.

Now this is for the “my block” named “Height” (See pic 6):

Define - Height (Number)
  if {not{(pick random 1 to 2)=1}}
    set Slope to 0
   else
     if {(pick random 1 to 3)=2}
       set Slope to -1 
      else
        set slope to 1
  if {4<(Height)}
    set Slope to -1
  if {(Height)<2}
    set Slope to 1

We are almost done (See pic 7):

when I start as clone
  if {costume name = Landscape slope}
    change size by 2.5
    change y by -3.6
  show

Now we are done!

Your done!Use your imagination to make this into anything.If you did it correctly it should look like the picture above, to make sure just click that flag and see it generate a random landscape.Hope you like it!
