You have learned how to use normal variables such as "food = 1." These can limit you tho, so I am going to teach you about arrays. Arrays are kind of like a variable inside a variable.
1D arrays are arrays containing 1 variable. It will look like this:
You will notice the box after the variable name. This looks similar to alarms but can go all the way up to 32000. Arrays can be used for anything such as setting up intro's, making an inventory, or simply making an easy to remember variable.
