Subject: [PATCH] Only send maps in item frames upon tracking
|
|
|
|
Maps in item frames are full of bugs.
|
|
1) It sends an update of the Maps data to ALL players in the world, not just the players tracking it.
|
|
2) It sends an update EVERY tick, not every 10 ticks as intended.
|
|
|
|
To optimize performance of maps in item frames, we will only send it once a player tracks the ItemFrame until it completes, then that player will not receive more updates.
|
|
|
|
This means cursors will not dynamically update, but the map data should refresh every time the player moves away then back.
