I'm making a map where you have to "capture" all the beacons by changing their color. Is there any way (in single player vanilla Minecraft) to detect when a beacon color is changed? I was thinking of maybe using observers, but those would only detect if any block was placed there.
Ok guys I finally found the command. it goes as follows:
/execute @a ~ ~ ~ detect ~ ~1 ~ minecraft:stained_glass 0
but there is another problem. now I need to know (please don't call me a noob but) how to add 1 to a players score I simply can't figure it out. Help? (again) btw this is what will go in place of (command).
