# Launchpad
Launchpad is a simple but configurable plugin able to make any placeable block into a launchpad which launches a player
with the desired velocity in their current or in a fixed direction. While anything can be a launchpad, pressure plates
have more accurate hit-detection as that's built into Minecraft.
Launchpads will prioritize values specifically set for that launchpad. If not set, they will look for material-specific
values. If not set, they will look for the generic velocities in the config.
## Known problems
#### Jumping on a pressure plate causes a `Player moved too quickly` message in the console, and the player is weirdly glitched for a moment
This happens because the server thinks the player moved faster than it should, and forcefully prevents the player from
moving. Increasing `moved-too-quickly-multiplier` in `spigot.yml` may fix this issue.
## Commands
Note that changing a property for a block which isn't currently a launchpad will turn the block into a launchpad.
If you alter several launchpad values in succession, they'll all be applied to the next block you right-click.
| Command | Arguments | Description |
|-------------------------------|-----------------------------------------------------|----------------------------------------------------------------------------------------------------------|
| /launchpad add | | Makes the clicked block into a launchpad. |
| /launchpad remove | | Removes the clicked block as a launchpad. |
| /launchpad abort | | Clears any unprocessed launchpad modifications. |
| /launchpad verticalVelocity | Decimal number / "null" | Sets the vertical velocity for the clicked launchpad. Use "null" to unset. |
| /launchpad horizontalVelocity | Decimal number / "null" | Sets the horizontal velocity for the clicked launchpad. Use "null" to unset. |
| /launchpad velocities | <Decimal Number / "null"> <Decimal Number / "null"> | Sets the horizontal and vertical velocities at once. The first argument is for the horizontal velocity. |
| /launchpad fixedDirection | NORTH / SOUTH / EAST / WEST / "null" | Sets a fixed direction the launchpad will launch every player. Use "null" to unset. |
| /launchpad:reload | | Reloads the configuration and launchpads from disk. |
## Permissions
| Permission | Description |
|------------------|---------------------------------------------------|
| launchpad.admin | Gives all other permissions |
| launchpad.modify | Allows modifying, adding and removing launchpads. |
| launchpad.reload | Allows reloading the launchpad plugin. |
## Configuration
| Node | Type | Description |
|-------------------------------------------------------------|-------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| launchpad.materials | List | A list of materials, or material tags (+TAG_NAME), which are always treated as launchpads, without the need for manual registration. |
| launchpad.materialWhitelist | List | A list of materials, or material tags (+TAG_NAME), which can be manually turned into launchpads. Use this to prevent unwanted blocks from being turned into launchpads. |
| launchpad.verticalVelocity | Decimal number | The vertical (upwards) velocity applied to launchpads if not specified otherwise. |
| launchpad.horizontalVelocity | Decimal number | The horizontal (sideways) velocity applied to launchpads if not specified otherwise. |
| launchpad.materialVelocities.\<MATERIAL>.horizontalVelocity | Decimal number | The horizontal (sideways) velocity applied to launchpads of type \<MATERIAL> if not overridden for the block. |
| launchpad.materialVelocities.\<MATERIAL>.verticalVelocity | Decimal number | The vertical (sideways) velocity applied to launchpads of type \<MATERIAL> if not overridden for the block. |
| launchpad.particles.trailsEnabled | True / False | Whether to enable particle trails behind players |
| launchpad.particles.trailSpawnDelay | Positive integer | The amount of ticks (1 second = 20 ticks) between each time the particle(s) of a trail should be spawned. |
| launchpad.particles.trailType | [Particle](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Particle.html) | The type of trail to spawn behind launched players. |
| launchpad.particles.randomTrailType | True / False | Whether to use a random value from randomTrailWhitelist as the trail on each launch. |
| launchpad.particles.randomTrailWhitelist | List | A list of all [particles](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Particle.html) selectable for random trails. |
| launchpad.particles.enabled | True / False | Whether to display some kind of particle effect above manually added launchpads. |
| launchpad.particles.spawnDelay | Positive integer | The amount of ticks (1 second = 20 ticks) between each time the particle(s) should be spawned again. Depending on the particle, higher values will make the particle(s) completely disappear and reappear. |
| launchpad.particles.particle.mode | SINGLE / SQUARE / PYRAMID / SPHERE / CIRCLE / CUBE | The mode used for drawing particles. SINGLE directly spawns the particle(s) in one spot above the launchpad. The other ones spawn particles a bunch of times in a pattern. |
| launchpad.particles.particle.type | [Particle](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Particle.html) | The type of particle to spawn above launchpads. |
| launchpad.particles.particle.amount | Positive integer | The amount of particles to spawn. Use 1 if mode is anything except SINGLE, unless you know what you are doing! |
| launchpad.particles.particle.offsetX | Decimal number | The offset, or spread of the particles in the X direction, relative to the launchpad |
| launchpad.particles.particle.offsetY | Decimal number | The offset, or spread of the particles in the Y direction, relative to the launchpad |
| launchpad.particles.particle.offsetZ | Decimal number | The offset, or spread of the particles in the Z direction, relative to the launchpad |
| launchpad.particles.particle.heightOffset | Decimal number | The amount of blocks above the launchpad the particle should spawn. 0.5 = half a block. 1 = one block. |
| launchpad.particles.particle.particleDensity | Decimal number | A definition for the number of particles used to draw shapes. The number of particles is basically `distance / particleDensity`, so lower numbers create a more dense shape. |
| launchpad.particles.particle.extra | Decimal number | Extra data for the specific particle. Check the Spigot documentation for details. |
| launchpad.particles.materialParticles | Configuration section | This section allows specifying different particle configurations for a material or a material tag. So you'd set materialParticles.LIGHT_WEIGHTED_PRESSURE_PLATE.type to set the particle type for LIGHT_WEIGHTED_PRESSURE_PLATE. |
