Hi,

Please help.

 

Oops 1.6.2. It looks like somewhere in your server, or one of your plugins, tried to pass Level object through. Have you try removing all the Plugins for a moment?

 

I have no idea what this means. Probably will never be able to fix it :/

What sort of code using level stuff would cause this issue. I can then look thru plugin codes to see the culprit

 

Iv had clearlag and economy land for about a year and never did the server crash for this reason till about 1-2 months ago

 

Try getting a backtrace using debug lvl2 or using php with debug..

 

How can you forget it if a broken one is right at the first post? And that reminds me that no-one ever has found out why tf they sometimes break on windows. I guess #BlameMicrosoftSoHard

 

How do I get a backtrace? I use a host where I only have access to the files and the php binary is not editable

 

Debug level 2 in pocketmine.yml

console back trace only appears with debug level 2

 

Thanks i will enable that and see what it shows. meanwhile, after looking thru the plugins, the ColorMatch plugin is the only plugin where isLevelGenerated is used the most. its also a fairly recently installed plugin.

Places iv found this:

PHP:

if(!$this->getServer()->isLevelGenerated($this->cfg->getNested('lobby.world'))){
            $this->getServer()->generateLevel($this->cfg->getNested('lobby.world'));


PHP:

if(!$this->plugin->getServer()->isLevelGenerated($this->data['arena']['arena_world'])){

PHP:

if(!$this->plugin->getServer()->isLevelGenerated($this->data['arena']['leave_position_world'])){

 

The ColorMatch plugin was the culprit. Any idea how I can fix this plugin to stop it crashing cos of this "isLevelGenerated" thing?

Any help would be much appreciated

 

So how would I do that? like: if(!$this->plugin->getServer()->isLevelGenerated($this->getServer->getLevel("worldname")){ ?

 

Sorry I'm fairly new to all this so I don't really get how I would change the original code to what your saying.

would this work?
$level = $this->getServer()->getLevelByName($this->data['arena']['arena_world']);
if(!$this->getServer()->isLevelGenerated($level);

If I'm wrong please tell me what would be the exact code I would replace the original with.

Sorry for the inconvinence.
