I have managed to figure out most of this scoreboard system out myself but this last part has me beaten.
i have a dummy Objective called "deaths" and would like to test when this score hits 10 for team_blue and team_red.
I currently have;
but this is not working. I am also using;
This is to test when a player dies and adds that to the "deaths" score, and that works perfectly fine. Is there an issue of using dummy objectives in the testfor command. Console output only says "That players cannot be found"
I am including a world download for testing purposes. Please note the objective names have Changed. Red and Blue carpet mark Teams and Signs give information. This is for vanilla 1.7.2: https://dl.dropboxusercontent.com/u/189120588/Minecraft/testfor%20world.zip
