Subroutines are used to easily "jump" to a set of commands within the script.
Subroutine:
A subroutine is created with the next command:
name: //code goes here RETURN
| name | An unique name for the subroutine. Note the : at the end of the name! |
|---|---|
| RETURN | This closes the subroutine. Every command in the subroutine has to be between the name: and RETURN. |
You can script the subroutine where ever you want, even before LEVELSTART!
FORWARD
To activate a subroutine at the start of the game, use this command:
FORWARD name:
The FORWARD must be before LEVELSTART
GOSUB
To jump to the subroutine mid-game, you use the next command:
GOSUB name:
Again, don't forget the : at the end of the name. A GOSUB can be everywhere where you want to jump to the subroutine: inside an IF, a WHILE, etc, as long as it's after LEVELSTART.
