Make your own variable without going inside a project! Button instructions: Make a variable - create a variable. Set variable to - works as a "set variable to" block. Change variable by - works as a "change variable by" block. Delete a variable- deletes ONE SPECIFIC NAME variable. Delete all variables - deletes EVERYTHING.
Something might went wrong if you trying to add something that is NOT A NUMBER to a variable. So never do so. Again, no swearing and rude comments, else it will got reported straight away.
