Custom Action System

• There is an actions setting in each detection item, and the format of the penalty operation is given below:
• Penalty Type Object A[ Relation] Object B Other parameters
• The penalty types supported by connecting multiple penalty operations with &&
• are as follows:
• cancel Lag back a player
• log Record the invalid action in NCP Logger，parameter break The Cooling Time
• warn Send a warning message to player，parameter message The message you sent
• kick Kick a player from server
• ban Ban a player from server，parameter repeat Fault Tolerance Times,time Duration Of Ban
• If no parameter is set, the plug-in will use NCP default value
• to add warning message, which needs to be added in string.

NCP Commands Permission

• Set it in permission.policy, and the format is:
• `Permission: Command Table'
• commands are connected by commas(,).
• If there is no record of a command in NCP, all players can use it by default.
• For example, the version is not specified in nocheatplus.admin.all and nocheatplus.admin.helper of the case.

NCP Custom Bypass Permission

Add them in permission.bypass，and the format is:

• CheckType:Permissions(List) The player who has these permissions will bypass the check.

• MOVING_SURVIVAL_FLY
• MOVING_CREATIVE_FLY
• MOVING_VEHICLE
