red = redstone wire, yellow = repeater, gray = empty, pink = trigger (pressure plate in my case)
The wire is unseen to the player of course.
Once plate is pressed, the wire activates command block with a message, and repeater makes it only 1-time trigger because it stays powered forever. But often the message will appear twice (at the same time) if player presses both plates at once (they're all connected to the same wire, I must use more than 1 plates because you can't predict where player will be going).
What should I do to fix this?
