WHILE is almost identical to IF, but the commands in a WHILE will loop as long as the expression is true, whereas the commands in an IF will be executed only once.
WHILE ( expression ) //command ENDWHILE
| expression | The situation that triggers the commands between WHILE and ENDWHILE. |
|---|---|
| command | The commands that have to be triggered by the expression. |
| ENDWHILE | Every WHILE must end with an ENDWHILE. |
To activate all commands within a WHILE at once, in stead of one by one, you can use the WHILE_EXEC command. Be carefull when using these, as to much WHILE_EXECs will slow the game down. Often the delay of a normal WHILE is barely noticeable.
WHILE_EXEC ( expression ) //command ENDWHILE
WHILEs and WHILE_EXECs can be extended with NOT, AND and OR in the same way as with IF.
