Dead plugin, please dont use it if you want to waste your time
As i saw in their discord the discord is dead also and the issue
"Error occurred while enabling LaunchPads v2.1 (Is it up to date?)
The embedded resource 'config.yml' cannot be found in plugins/LaunchPads-2.3.0.jar" wich prevent the plugin to start has been announced a year ago almost the owner never answered it or fixed it.

Can you allow us to set Slime Blocks to be launchers too? Pressure plates aren't what our server is looking for :>

It's so interesting! Can I share it with Chinese websites?
I will mark your post, they can download it here
