| A '''Boolean''', or '''Bool''' value is a very simple type of data. It can be either '''true''' or '''false'''. That's it. Either yes or no.
| |
| | |
| In Lua, everything that has a value is treated as '''true''' when converted to a boolean, unless it is '''nil''' or '''false'''.

| One easy way to think of Boolean values is as a light switch. A switch has two positions, on and off. So when you flip the switch, you change it from one to the other.
| |
| | |
| The same idea works with bools, and you may also hear people say things like "flip the switch to true", or something similar. This is because a lot of people think of bools as switches.

| Booleans are really easy to use. Like so:
| |
| <pre>
| |
| MyBool = true
| |
| | |
| if MyBool then
| |
| --If "MyBool" is true, this code is run.
| |
| else
| |
| --If "MyBool" is false, this code is run.
| |
| end
| |
| </pre>
