FPK Mod

An open source replacement for MPK Mod, MPK Mod 2, and CyvClient, for 1.8.9 forge (a 1.12.2 port is planned).

Adds a bunch of useful parkour features to the game. Client side only!

While it is intended as a replacement, it should work alongside MPK.

Current Features

• Most labels and commands from MPK, and a little more (see tables below)
• Landing blocks

Landing blocks are massively improved over MPK (way better wall calculations, better setlb command, float precise offsets, etc...)

The current priority is to add all MPK and CyvClient features, then to add new stuff.

Labels

Labels show useful information on screen.
You can edit their position and visibility using /fpk gui.

Label	Description
Version	The mod and game version
FPS	The current FPS
X	The player's position on the X axis
Y	The player's position on the Y axis
Z	The player's position on the Z axis
F	The player's yaw. Also shows the axis the player is facing
Raw Yaw	The raw, unmodified yaw value
Pitch	The player's pitch
Date	The current date
Time	The current time
IP	The current server IP
Jump Angle	The yaw on jump tick
Jump X	The X position on jump tick
Jump Y	The Y position on jump tick
Jump Z	The Z position on jump tick
Hit Angle	The yaw on hit tick
Hit X	The X position on hit tick
Hit Y	The Y position on hit tick
Hit Z	The Z position on hit tick
Last Landing X	The X position on the tick before hit tick
Last Landing Y	The Y position on the tick before hit tick
Last Landing Z	The Z position on the tick before hit tick
Speed X	The speed on the X axis
Speed Y	The speed on the Y axis
Speed Z	The speed on the Z axis
Speed Vector	The speed vector, shown as magnitude/angle
Max Speed X	The highest speed achieved on the X axis. Resets when the movement direction changes, the player stops moving (configurable), or /fpk clearmaxspeed is run
Max Speed Y	The highest speed achieved on the Y axis. Resets when the movement direction changes, the player stops moving (configurable), or /fpk clearmaxspeed is run
Max Speed Z	The highest speed achieved on the Z axis. Resets when the movement direction changes, the player stops moving (configurable), or /fpk clearmaxspeed is run
Max Speed Vector	The vector of the highest speed achieved, shown as magnitude/angle
Run Ticks	The amount of ticks the player has been running on the ground for
Last Input	The current WASD input
Jump Input	The WASD input on jump tick
Last Turning	The size of the turn made on the last tick
Preturn	The size of the turn made on the tick before jump tick
Last 45	The size of the turn made on the tick after jump tick, if the player started strafing
Airtime	The amount of ticks the player has been in the air for
Tier	The jump tier
Grinds	The amount of grinds chained
Keystrokes	The current WASD, sprint, jump, and sneak input in a familiar looking interface
Togglesprint	Whether togglesprint is enabled or disabled

Commands

Some commands have a keybind shortcut (unbound by default).
Certain commands can also be run by right-clicking signs with the command and command arguments on them.

Command	Description
/fpk	Same as running help
/fpk help	Sends a list of all commands and their help text in the chat
/fpk config	Opens the main config GUI
/fpk reloadconfig	Reloads the config file
/fpk gui	Opens the label config GUI
/fpk df <precision>	Changes the decimal precision. Range from 0 to 16
/fpk setlb [target|below|x y z] [land|zneo|enter|hit] [box] [x|z|~]	Sets the landing block. The first argument specifies what block to select (defaults to target). target will select the block the player is looking at, below will select the block the player is standing on, and x y z will select the block at said coordinates. The second argument specifies the landing mode to use (defaults to land). The third argument specifies whether to use box mode. The last argument specifies the axis the offsets should use. Arguments after the first can go in any order. See more in Landing Blocks
/fpk clearlb	Clears the landing block
/fpk clearpb	Clears the landing block PB
/fpk setcond <minX> <maxX> <minZ> <maxZ>	Sets the landing block condition box to the provided coordinates. The Y coordinate is reused from the previous condition box
/fpk anticp [duration]	Enables/Disables antiCP. If a duration is provided will set the antiCP duration to that instead
/fpk toggleall	Toggles visibility of all labels
/fpk resetlabels	Resets all labels to their default positions
/fpk clearmaxspeed	Resets the max speed labels back to 0
/fpk fly	Enables/Disables flight when in creative mode
/fpk togglesprint	Enables/Disables togglesprint
/fpk tp <x> <y> <z> [yaw] [pitch]	Improved version of /tp. Allows teleporting to saved coordinates if no arguments are given
/fpk coords <save|copy|clear>	Manages the player coordinates. Allows copying the current coordinates to the clipboard and saving said coordinates for use with /fpk tp

Landing Blocks

Landing blocks let you see how much you missed/made by on a jump.
You can set one on a block with the /fpk setlb command, or with the command keybind, and edit its properties in the /fpk lb GUI menu.

The landing block GUI has 5 buttons:

• Land Mode lets you change the block's landing mode
• Axis lets you change what axis the offsets should use
• Render LB lets you choose whether to render the landing block in the world
• Render Cond lets you choose whether to render the condition box in the world
• Recalculate Walls will recalculate the walls around the landing block, useful if they change

The landing mode specified changes how an offset is calculated and different modes are useful for different types of jumps:

• Land is the default and should work fine for most jumps
• Z Neo is useful for Z facing neos where you can slide off a wall next to the landing block
• Enter is useful for climbing ladders or vines (or any other climbable block)
• Hit is useful for bouncing on slimes

A landing block created with box mode will get the offset from the player coordinates instead of using the player hitbox, meaning it will check whether the player is "inside" a block instead of simply being able to land on it. This is useful for climbing ladders/vines and bouncing on slimes.

If antiCP is enabled, all right-clicks will be blocked for a specified amount of time upon landing on a landing block. This is useful to prevent accidental use of teleport items.

Planned Features

• MPK Labels
  • Blip
  • Last Timing
  • All the LB labels
• Cyv Labels
  • Last Sidestep
• Input and turn history
• Multiple landing blocks
• Macro
• Some kind of jump/strat manager thing
• Stratreminders
• Something something mothball?
• 1.12.2 version (not happening soon)

Please make a feature request if there's something you want that isn't in this list!
