Behavior
Exclusive Targeting
The mob only attacks the player specified in the command. Other players cannot be attacked by the mob, even if:

• They are closer to the mob than the target
• They attack the mob
• The target player is far away

Visibility

• Only the specified player can see the mob
• Other players cannot see the entity at all
• Visibility is maintained even if the player reconnects

Enforcement System
The plugin utilizes a continuous enforcement system that:

• Runs every tick (20 times per second)
• Verifies that the mob has the correct target
• Forces targeting if it has changed
• Automatically cleans up dead or invalid mobs

Technical Details

• VisibilityManager: Manages mob visibility every tick
• TargetEnforcementTask: Forces the correct targeting every tick
• SpawnCommand: Handles the command execution and mob registration

API Usage

• MythicMobs API: Used for spawning and mob control
• ProtocolLib: Used for visibility management (packet interception)
• Bukkit Scheduler: Used for handling asynchronous tasks

Party System (MMOCore)
The plugin integrates automatically with the MMOCore party system:

• Automatic Detection: The plugin detects if the target player is currently in a party
• Shared Visibility: All party members are able to see the mob
• Shared Targeting: The mob will attack the target player or any nearby member of their party
  
  
• Dynamic Updates:
  • If someone joins the party They see the mob and can be attacked
  • If someone leaves the party They lose visibility and the mob stops attacking them
  • If someone reconnects Their status is correctly restored based on their party membership

Exclusive Targeting (Party)
The mob attacks only the specified player and their party members. Players outside the party cannot be attacked, even if:

• They are closer to the mob
• They attack the mob
• The target player is far away

️ Visibility

• Shared Access: Only the specified player and their party members can see the mob
• Complete Stealth: Other external players cannot see the entity at all; it is completely invisible and non-existent to them
