| == Introduction ==
| |
| A Bool, or Boolean Value is a <b>true</b> or <b>false</b> value. In Lua, either the value is <b>true</b>, or it is <b>false</b>/<b>nil</b>. When trying to change this value in code, use a <b>true</b> or a <b>false</b> variable.
| |
| | |
| These variables show up as a checkbox in the Properties window. <b>True</b> is a checked box, <b>false</b> is an unchecked box.
| |
| | |
| == Examples ==
| |
| <pre>
| |
| x = true
| |
| print(x)
| |
| Will result in:
| |
| true
| |
| | |
| x = true
| |
| print(not x)
| |
| Will result in:
| |
| false
| |
| | |
| print(not false)
| |
| Will result in:
| |
| true
| |
| </pre>
| |
| | |
| Boolean values are used to represent the results of logic tests. The equals ==, and not equals ~= operators will return boolean values depending on the values supplied to them.
| |
| <pre>
| |
| print(1 == 0) -- test whether two numbers are equal
| |
| Will result in:
| |
| false
| |
| | |
| print(1 == 1)
| |
| Will result in:
| |
| true
| |
| | |
| print(1 ~= 0) -- test whether two numbers are not equal
| |
| Will result in:
| |
| true
| |
| | |
| print(true ~= false) -- is true not equal to false?
| |
| Will result in:
| |
| true
| |
| </pre>
