A boolean value can also take place in a script, like debounce. Boolean Values and Number Values are probably the most useful in my point of view, Boolean Values are my best friends, well, Lolfunny12345 is my best friend.

You could have an inventory model, which had lots of boolean values, each named after a sword, and if the sword = true then the sword would clone to the players Backpack.

That meant if the person is a noob, then they will be killed, that is just one of the simple things you can have done with a value.

Somehow with a Value everything can be simpler, most of the Values I uses are implemented on the if statement, for example: On the current game I'm making, Forgotten Fate, I have used a various amount of Values with a varied choice of which Value, I used the Boolean Value on a crop field, and a String Value for finding the crop that you want to plant. If you are to be a successful ROBLOX scripter, on your journey you must learn a Value, so I'm gonna teach you. When being a scripter, having values are essential, I could use a few Values to make a simple inventory system, or to tell whether a plowing field is being used, using a Boolean Value.
