How it works · RoodyPads · Documentation

Velocity = the direction the player looks (horizontal only, unless usar-inclinacion: true) × fuerza, plus altura upwards.
Works even when another plugin (WorldGuard at spawn) stops the plate from being pressed.
Per-player cooldown so nobody is launched several times in a row.
No fall damage: the first fall is cancelled until the player touches the ground again (checked by the server, not what the client says) or for proteccion-caida seconds.
