General
This page explains configuration options which affect or support multiple moving checks.
velocity activationcounter
Queued unused velocity is removed after this amount of incoming moving packets. Decreasing this will nerf some abuses (such as long-jump) but it could also create more false positives (lag(...))
velocity activationticks
Queued unused velocity is removed after this amount of server ticks. Decreasing this will nerf some abuses (such as long-jump) but it could also create more false positives (lag(...))
velocity strictinvalidation
More strict invalidation of queued velocity.
splitmoves
TODO:
ignorestance
Ignore the bounding box check for players. This can be used to prevent compatibility issues on legacy setups. Set to default, it will disable from 1.8 on. Force set with true/false.
tempkickillegal
Setting this to false will just kick a player that does a illegal movement instead of actually tempbanning him for 24 hours. Technically NCP uses its deny login feature, only counting until next restart, not the ban command.
loadchunks join
Should NCP load chunks around the player when joining the server before checking? (Prevents some types of false positive caused by lag)
loadchunks move
Should NCP load chunks around the player when moving before checking? (Prevents some types of false positive caused by lag)
loadchunks teleport
Should NCP load chunks around the player when teleporting before checking? (Prevents some types of false positive caused by lag)
loadchunks worldchange
Should NCP load chunks around the player when changing world before checking? (Prevents some types of false positive caused by lag)
sprintinggrace
Grace period for which SurvivalFly will let the player walk at sprinting speed even though their sprint has been toggled off (latency) (seconds)
assumesprint
This workaround will let NCP assume that the player is ALWAYS sprinting whenever possible.
speedgrace
Grace period for which SurvivalFly will let the player walk as if the speed effect was still active (latency) (seconds)
enforcelocation
Track if the player has somehow managed to get to ridiculous places without a moving event firing. Fixed the vehicle-teleport exploit. Legacy option for some time before Spigot 1.7.10. Setting to default will activate/deactivate based on the detected Minecraft version. Force set with true/false.
setback method
Technique of setting back players. Legacy before MC 1.9: "set_to" The set_to setting will lead to problems since MC 1.11.2 since 2017-03-24, because TeleportCause.PLUGIN will result there, leaving potential for misinterpretation by other plugins. For MC 1.11.2 but also for 1.9 and later, the setting "cancel+update_from+schedule" is the default, it would cancel moving events, and induce teleporting to the set back location by updating the from location, with a fall-back check on-tick (schedule). The defaults can be referenced via their ids: default.legacy for pre-1.9, default.modern for latest (currently post-1.9), default.cautious for the latest with potential risks disabled (such as the teleport skipping condition using packet level ack). Using the default flag only will let NCP adjust by itself according to the detected server version.
illegalplayermove
Kick and log this message to players who try to use certain exploits.
There are also hidden options, which give more access to internals. Use with care, as these might allow different kinds of cheats or lead to other false positives, if changed. Ask back if in doubt or test changes made.
yonground
Control the vertical distance to blocks, at which NCP will assume the player to touch ground. This affect any moving-related checks, dealing fall damage etc. Capped at a maximum value of 0.0625, and a minimum of 0.00001. The default value may be around 0.016. Adjusting this to something higher might allow moving slightly above cactus without taking damage, but it might also help on certain false positives. Changes should be tested with issues that can be reproduced at will.
Players could do a illegal movements which would crash the server, so we made a check against it that would tempban a player for 24 hours if they exploit that. However some users wanted to just kick such players and for that reason we put boolean to activate/deactivate temporary banning called tempkickillegal.
If you use plugins that allow 0 delay between two hits, reduce velocity.activationcounter and velocity.activationticks to something lower.
The assumesprint workaround is needed for the long-standing bug that has been introduced in MC 1.7 with the CTRL sprint feature. The server doesn't properly reflect the sprinting state of the client, causing a ton of false positives.
The Minecraft client moves (well more falls) even if no chunks are loaded up which could trigger a tiny Passable false positive. We tried to smooth this further out by loading up the chuncks on join as fast as possible with loadchuncks _join_. It seems that Mojang allows the client to move inside unloaded chunks, for the vanilla fly check because it would prevent false positives with it.
