However if someone is looking for a beginner issue, then this *might* be something to have a look at. \r\nNote however we are uncertain if this should actually be considered a beginner issue, and would probably classify it as beginner++. \r\n\r\n## Description\r\nMake it so that when mobs or players change their equipment, other clients see the selected item.  So if a player/mob equips a sword or some armour it would be visible to others. \r\n\r\nTo do this one has to send the [EntityEquipment](https://github.com/feather-rs/feather/blob/567262c7724d423d3e3ad8dc660b89ef8c72c290/feather/protocol/src/packets/server/play.rs#L948) packet every time an inventory is changed in a visible way. \r\n\r\nTo send send a packet to all nearby players, you call the [broadcast_nearby_with](https://github.com/feather-rs/feather/blob/567262c7724d423d3e3ad8dc660b89ef8c72c290/feather/server/src/lib.rs#L125) on the Server struct. \r\n\r\nThis code should probably be made into a [system](## \"Systems: functions that run each tick. While components are data, systems are logic. They operate on components.\"). And would therefore be put into [this folder](https://github.com/feather-rs/feather/tree/main/feather/server/src/systems/entity). Remember to register the system like it is done [here](https://github.com/feather-rs/feather/blob/567262c7724d423d3e3ad8dc660b89ef8c72c290/feather/server/src/systems/entity.rs#L15).\r\n\r\nI am not sure what the best approach is for detecting a visible change in a inventory slot.\r\nAnd to do this well the problem might actually turn into an issue that is less beginner friendly. So a first approximation to the problem, would be to trigger the packet every n'th tick, and add a todo comment.  \r\n\r\nIf you have gotten everything else working and feel like doing something smarter then what I have suggested then I  would ask someone on the discord, or on this issue to see if they agree with your approach.
