/fly¶

This plugin adds a /fly command that turns flying on and off each time you use it.

plugin.addCommand({
    name = "fly",
    description = "Toggle flying",
    usage = "/fly"
}, function(event)
    local player = event.getSender()
    local canFly = not player:getAllowFlight()
    player:setAllowFlight(canFly)
    if canFly then
        player:sendMessage("Flying is on! Double-tap space to fly.")
    else
        player:sendMessage("Flying is off.")
    end
end)

How it works¶

player:getAllowFlight() asks whether the player is allowed to fly right now, and the answer is either true or false. Putting not in front of it flips the answer, so true becomes false and the other way around, and we save that as canFly. Then player:setAllowFlight(canFly) applies it, which is why the command works as a switch.

The if part picks a message to send. If canFly is true the first message runs, and otherwise the one after else runs.

Next: /rules.
