Hello SafeRedDoor-,
You can use variables to store some information and use it later.
In order to create a variable, you can use the "Var" command.
In order to change the variable value, you can use the "Set" command.
You can also assign the variable's value to anything in your game by using the "Set" command.
For example, let's say you want to print a variable on the screen, In that case, you can create a "Label" and inside that label use the "Set" command where the "var" will be the "text" property of the label and the value will be the variable you have created.
If you have further questions about variables please ask and we will do our best to explain it.
