Description
A launch plate (or launchpad) is created by placing a pressure plate on top of any chosen block. When a player steps on the plate, he/she will be launched upwards to any configurable height. The type of block and type of pressure plate are both configurable in the config.yml and can be set using commands. The default block is obsidian with a gold pressure plate placed on top.

The height to which the player is launched is controlled by the "force" variable in the configuration file, set with the "/lp setforce" command. The actual height achieved can be controlled to a good degree of accuracy by specifying the force as a decimal. The default force is 0.8 which will launch the player about 16 blocks up. Unlike a lot of similar plugins, there is no limit to the height a player can be launched to. So, for example, a force of 4.0 will launch the player about 60 blocks up, while a force of 8.0 will launch the player about 128 blocks up.

No fall damage is inflicted on the players, so LaunchPlate can be used in any gamemode.

LaunchPlate can be used as a fun addition to a lobby/hub or even as an extension to a parkour course.

LaunchPlate is super easy to use, changes are made by command using tab completion, and are instant (no need to reload the plugin).

Default Configuration File




Commands

This plugin uses tab-completion making it very simple to select and test different sound and particle effects. The changes are instant (no need to reload the plugin).



The plugin LuckPerms uses the same command alias lp, so although tab completion makes this redundant to some extent, there is an additional lpl alias which can be used for LaunchPlate if you also have the LuckPerms plugin on your server.


All of the above require launchplate.admin permission



Permissions
Setting permission launchplate.use: false in worlds where LaunchPlate is not used or not required should make a small performance improvement.

Installation
For upgrading, check the release notes for each release.
