MCPK-bot is a Discord Bot aiming to replace MathBot for movement calculations. Indeed, it was getting tiresome to redefine functions all the time, and the syntax is not very convenient to use. MathBot is still very useful as a general-purpose calculation tool.

Advantages over using Mathbot:

  • Richer and more descriptive outputs
  • The functions are built-in: no need to redefine them manually.
  • The bot uses float math instead of fractions, so the simulation is more accurate.
  • For simulating movement:
    • X and Z movement are both considered, and momentum threshold is taken into account.
    • Actions are read from left to right, which is way easier to read and write.
    • All actions take direction as an optional argument.


Distance

%distance <X> [Z]

Returns the real distance of a X by Z jump (distances in blocks, Z is optional)

The formula is simply

Examples:

  • 4b jump: %distance 4
  • 3x3 jump: %distance 3 3


Duration

%duration <jumpHeight> [ceilingHeight]

Returns the duration of a jump with the given height (heights in blocks, ceilingHeight is optional)

Examples:

  • -1.5b jump: %duration -1.5
  • 3bc +1 jump: %duration 1 3



Height

%height <jumpTicks> [ceilingHeight]

Returns the jump height of the player after n ticks (ceilingHeight is optional)

Examples:

  • 12t jump: %height 12
  • 2bc 9t jump: %height 9 2


Blip

%blip <repetitions> [initialHeight] [blipHeight] [lastJumpTicks]

Returns the height of the player after chaining consecutive blips (Y=0 is the bottom surface by convention).

  • <repetitions> is the number of chained blips performed
  • [initialHeight] is the player's initial height before the first jump (default: 0.0)
  • [BlipHeight] is the height of the blip's top surface (e.g. 0.0625 for carpet, 0.1875 for trapdoor...)
  • Unless specified with [lastJumpTicks], returns the peak of the jump by default (6 ticks).

Examples:

  • starting from Y=200: %blip 4
  • 17 chained blips on lilypad: %blip_top 17 0.015625


Simulate

%simulate <actions> (or simply %<actions>)

Reads the given actions from left to right, and simulates the resulting movement.

Actions:

Actions take two arguments:

  • Ticks : the duration of the action, in ticks
  • Direction (optional) : the direction (not facing) of the action, in degrees
Action Description
stop, stop_air No input
sneak, sneak_air Sneak
sneak45, sneak45_air Sneak with 45° strafe
walk, walk_air Walk
walk45, walk45_air Walk with 45° strafe
sprint, sprint_air Sprint
sprint45, sprint45_air Sprint with 45° strafe
stopjump Jump without moving
walkjump Jump without sprinting
walkjump45 Jump without sprinting, 45° strafe throughout the jump
sprintjump Sprintjump
sprintjump45 Sprintjump forward, start 45° strafe after the first tick
Lsprintjump

Rsprintjump

Strafe Left or Right on the first tick of a sprintjump.

Example: used for rex bwmm

Lsprintjump45

Rsprintjump45

Strafe Left or Right throughout a sprintjump.

Example: used for 1bm 5-1

Add "max_" in front to get the maximum momentum with that action.

Tokens:

  • Momentum, MM, and | sets the previous actions as momentum (resets the position minus the last tick)
  • Blocks and b convert the output landing distance to blocks (± 0.6 to X and Z if nonzero)
  • Meters, and m convert the output landing distance to meters (same values as default)
  • Position, pos, and p convert the output to (used when you're not calculating jump distance)

Usage:

The parser reads the actions and tokens from left to right. Actions and tokens should be separated by spaces.

The Momentum token can be used anywhere between two actions.

The Blocks, Meters, and Position tokens are to be used at the end of the sequence (mutually exclusive).

Examples:

  • hh timing: % sprint | sprintjump(12)
  • rex bwmm: % walkjump(12,180) walk(1,180) Lsprintjump(12) | sprintjump(12)
  • 1bm 5-1: % walkjump(12,170) walk(1,170) Lsprintjump45(1,-10) sprint45_air(11) | sprintjump45(14) b
