[Question] Prevent the client from highlighting block in line of sight.

  1. Hi,

    My question today is how do servers prevent the player's client from being able to see a highlight around a block in their line of sight? For instance, Hypixel, WynnCraft, and a few other servers are able to prevent the player from seeing the highlight box that goes around a block when it is in line of sight.

    I imagine it may be done with packets. Maybe the blocks the player is looking at are sent to the client as air blocks, so the highlight/selection isn't displayed. I have done many google searches on the subject, but I haven't be able to find anything.

    Thanks!
     
  2. The outline around a block when you target it? Set the player to adventure mode.

  4. Make a custom texturepack for it, and force players to use it, using a resource pack forcer plugin, or set players gamemode to adventure, if you don't need to allow them the breaking of these blocks.
