is there a way to show a players score on a sign?

Question

is there a way for a specific players score from a scoreboard to be shown on a specific sign. for example in a game of ice hockey a scoreboard shows the score of the 2 two teams (this would be the signs on minecraft)

this is a screen shot of what the physical and virtual scoreboard look like.

This is 1.8.3 minecraft for the pc!

Answer 1

You can do it with setblock. This is a great tutorial that I use a lot.

Basically, you can set the NBT data of a sign when you setblock it. Just do

/setblock ~ ~ ~ minecraft:wall_sign 0 replace {
    Text1:"{
        selector:\"@p[team=Team1]\"
    }",
    Text2:"{
        score:{
            name:\"@p[team=Team1]\",
            objective:\"points\"
        }
    }"
}

This will create a sign with the closest player from team Team1's name on the first line and their score in points on the second line. You can also color the lines, choose different players, etc. There is really a lot you can do with it.

I don't think that's possible on Vanilla Minecraft. However, you can write your own bukkit plugin, the tutorials on that's available all over the net.
