IF..ELSE

When checking for a condition, you can also specify what to do if the condition is not met. This is done with the else keyword.

An if statement with else has the following syntax:

if <condition>
then
// code to run if condition is true
else
// code to run if condition is false
end

Note that you can’t use else without then, and the else block must follow the then block.

Example:

if is_key_pressed 113 // F2
then
    print_help 'HELP_F2' // show message if F2 is pressed
else
    terminate_this_script // otherwise terminate the script
end
