Conditions

Often times you want to run some code only if a certain condition is met. For example, you might want to show a message if a certain button pressed.

To do this, you can use the if statement. It has the following syntax:

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

where <condition> is a single conditional instruction. It is written just like any other command, but after execution it changes the status of the current if statement to true or false.

If the status is true, the code inside the then..end block is executed. If the status is false, the code inside the then..end block is skipped:

if is_key_pressed 113 // F2
then
    print_help 'HELP_F2'
end

This script will show a help message only if the F2 key is pressed.
