v83 OpenPortal

[Z41N]

Hey everyone -

Trying to get the openPortal command to work, particularly in the Fitness Waiting Room map (109040000):

OpenPortalCommand:

public class OpenPortalCommand extends Command {
    {
        setDescription("");
    }

    @Override
    public void execute(MapleClient c, String[] params) {
        MapleCharacter player = c.getPlayer();
        if (params.length < 1) {
            player.yellowMessage("Syntax: !openportal <portalid>");
            return;
        }
        player.getMap().getPortal(params[0]).setPortalState(true);
    }
}

After finding the correct portal ID via !debug portal (23), then doing !openportal 23 I get the following error:

Here's the exact error log:

Error for player ; XXXX on map ; 109040000 - account ; YYYY
All: 31 00 0E 00 21 6F 70 65 6E 70 6F 72 74 61 6C 20 32 38 00

I thought maybe it was because I'm stating params[0] as the parameter instead of params[1], but that doesn't work (just how the commands are setup).

I'd like some help at being able to troubleshoot this.
I see jthere's obviously a NullPointerException at the command, but then is it the same error for all the lines below it? If so, what exactly does a NPE require me to do?

Thanks in advance

For one, the portal name on the Fitness Test Waiting room is "join00" also, in the command change:

Spoiler

player.getMap().getPortal(params[0]).setPortalState(true);

to

Spoiler

player.getMap().getPortal(params[0]).setPortalStatus(true);

There you go.

Thanks for the reply.
This works!

How did you know to change the state to status? I'd like to avoid wasting people's time haha
Thanks again

I've been messing around with HeavenMS source so I already had the source handy. When I saw your issue, I looked at the methods in MaplePortal.java. Really just went from there. Also, checked out your server but had to cut it short, might hop on more times just to see the progress. Wish you luck.

I appreciate that, thanks. Be well
