New page

jump <addr>

<addr> - is a gamevar obtained by [[getcurraddress]]

This command is also know as GOTO(http://en.wikipedia.org/wiki/Goto). Too bad this jump command isn't as good as it can be. It hardly can be used to jump forward because <addr> isn't known.

Here is en example. It countdowns the i variable from 10 to 0.
// addr and i are gamevars.
setvar i 10
getcurraddress addr
// begin loop
addlogvar i
subvar i 1
ifvarn i 0 jump addr // if i isn't 0, jump to addr

Yes, it could be done via [[whilevarn]] but it's just an example.
