Launchpad+ is a bukkit plugin by NizarZa123, is a launch with a plate, this plate you can do it in any block you want with 3.0D power x , and coming, the config with custom power x launch , you can use it in sand, redstone block, diamond block, stone , dirt without any command.
and with the wooden plate too he go 1.0D power x and deal anything on damage & stone too .
How to use it?
Isn't something so hard you need just only do your stone plate or wooden plate "not the golden one or the iron one" in the ground and pressure him and you go launch.
No video this moment.
