@ -9,7 +9,7 @@ MoreMesecons is a mod for minetest wich add some mesecons items.
### New items
* `Adjustable Blinky plant` : Like a mesecons blinky plant, but... adjustable. Right-click to change the interval.
* `Craftable Command Block` : A command block with just some commands accepted. The admin can change the accepted command (first line of the init.lua), default "say" and "tell".
* `Craftable Command Block` : A command block with just some commands accepted. The admin can change the accepted command (first line of the init.lua), default "tell". Only "@nearest" can be used in the commands, and the admin can change the maximum distance of "@nearest" (default 8 blocks).
* `Dual Delayer` : If it receives a mesecons signal, port 1 turns on immediatly and port 2 turns on 0.4 seconds later. At the end of the signal, port 2 turns off immediatly and port 1 turns off 0.4 secondes later. For example, this is useful for double extenders.
* `Player Killer` : This block kills the nearest player (with a maximal distance of 8 blocks by default) (if this player isn't its owner) when it receives a mesecons signal.
* `Signal Changer` : If it receives a signal on its pin "F", it turns on. If ti receives a signal on its pin "O", it turns off.
