Debugging

In order to test out bugs better you have three major options.

All these options are not really meant for (big) production servers, they can cause extreme console output and performance issues.

Mostly console output will be interesting, but also the in-game chat might be useful, check the output-client.log file to not need to use screenshots.

If you try to report a false positive and want to help finding the causes faster this can be very helpful. Rather send a little longer log not to miss out parts, so unless familiar with it you should add a little before and after the violation message of TestNCP for instance. For moving always at least from jumpphase=0 until the violation and "set back to..." a couple of lines below. If possible or not sure it is a singular issue, include a couple of violations.

Please use a paste or send as a file attachment by mail if the output is a little bit longer.

NCP Debug Output

For the most detailed output use a development build of NCP (or manually edit BuildParameters.properties in the jar and set DEBUG_LEVEL to something like 10000).

Then set a/the check-group debug flag, like moving.debug to true.

NoCheatPlus allows to set debug flags for almost all check groups. The flag in the logging section can also be set, but it will not lead to more check-output.

TestNCP

This plugin is found at the project site of http://dev.bukkit.org/bukkit-mods/ncptools/. TestNCP allows you receiving console and in-game output for every violation, even if logging would not normally show the message due to low VL for instance.

The plugins configuration allows setting testers, wither '*' for all players (spam), or the player names for distinct players.

Input about violations can be confined to individual players using /testncp input (player)

EventMirror

This plugin is found at the project site of http://dev.bukkit.org/bukkit-mods/ncptools/. EventMirror sends in-game info about players actions, to allow checking if certain events happened at all. It does not cover all existing events, though.

Any Player can use /mirror to receive events in-game. The messages are restricted to the player that is involved.
