The Variables folder contains the blocks need to create variables. Variables are a fundamental concept in programming that allow you to store and manage data throughout your program. They are like containers that hold values, and you can refer to them by their names to access or modify the values they contain.

They are useful for many reasons, like storing data, sharing data between blocks, reusing values, making the code more readable and improving the code efficiency.

Once you click on the variables folder you will be able just to see this screen (See image below). In order to create a variable you need to click on the "Create variable..." block and a window will pop up on your screen. You need to write the name of your variable, in this case "x", and then press OK. After this sequence, the variables folder will add several variable blocks with the value "x" that you can use in your program. If you want to add more variables the folder will put them in the order you create them, you will also be able to choose which variable you need in the drop-down.

We will show the way to delete a variable in the description of the different blocks.


The variable block is used when you need to use your variable in your program. You can connect it wherever you can find a block with a socket. The variable block will represents a value or a text string.

When you click on its options you can easily change which variable you are referring to, you can rename it or delete the variable itself.

Set variable

This is a fundamental block when you work with variables. You can use this block to assign a value, a text or an event message to a variable. By clicking on the drop-down you will find exactly the same options as in the variable block.

Change variable

With this block, you can change the value of the variable by adding the number contained in the blue block. By clicking on the arrow you will find exactly the same options as in the variable block.
