Solved Player Opacity

Hey I was looking at some random YouTube videos ('cause YOLO) and I came across this:

Does anyone know how the heck they did this?

 

Maybe by using packets? I don't know though.

 

i think its the new teams feature in minecraft, team mates can see their team mates?

 

I second that. read that somewhere. so everyone must be on the same team.

 

Oh, yes it is. Got this from a quick Google search:

 

Ok! Can someone give me an example of how to do this? Maybe Tzeentchful can because he knows a lot about the scoreboard/team packets...

 

Anyone? I really want to do this

create teams:

Code:

org.bukkit.World world = Bukkit.getWorld("world");
 
World mcWorld = ((CraftWorld) world).getHandle();
mcWorld.getScoreboard().createTeam("team1");
mcWorld.getScoreboard().createTeam("team2");

adding players to a team:

Code:

org.bukkit.World world = Bukkit.getWorld("world");
 
World mcWorld = ((CraftWorld) world).getHandle();
 
ScoreboardTeam team1 = mcWorld.getScoreboard().getTeam("team1");
mcWorld.getScoreboard().addPlayerToTeam(player.getName(), team1);

adding the opacity effect (aka can see if they are invisible):

Code:

org.bukkit.World world = Bukkit.getWorld("world");
World mcWorld = ((CraftWorld) world).getHandle();
 
mcWorld.getScoreboard().getTeam("team1").setCanSeeFriendlyInvisibles(true);
 

This should get you going
