About this project
What does ParkourCalculator add?
Parkour Calculator
A TAS input planning mod for Minecraft. Plan, simulate, and visualize parkour movement before you execute it.
The Parkour Calculator runs Minecraft's real movement physics tick by tick, so the path you see in the world is exactly how the player will move in game. It is not an approximation and there is no drift.

Features
- Tick-by-tick input planning: Set WASD, jump, sneak, sprint, yaw, pitch, and mouse buttons for every tick, and choose which columns are shown.
- Live path preview: The predicted path renders in the world as boxes and updates instantly as you edit.
- In-world editing: Drag the start box to reposition, drag individual ticks to retune facing, and select single ticks or ranges. Shift+drag a tick to move the whole path while keeping its offset locked.
- Angle solver: Give it your inputs and constraints, and it computes the yaw angles that satisfy them. Visualize constraints in the world, add a block's landing constraints with a hotkey, and tune the solver effort. It keeps up with Wolfram on single jumps and can handle long solves up to roughly 850 ticks and 200 constraints in under 10 seconds.
- Velocity finder: Sweep launch velocities against a jump and explore the results in a 2D/3D map to see which starting velocities land it.
- Configurable start state: Edit the start position, velocity, and attributes directly.
- Replay: Play your planned inputs in game from the start, a selected tick, or a range, pause and resume mid-run, and keep the path and input table visible while replaying (works only in singleplayer).
- Per-tick movement info: Motion, speed, and combined XZ distance for any tick, in a resizable, configurable Tick Info window.
- Customizable rendering: Full control over colors and visualization, with tooltips on every setting.
- Row operations: Add, delete, lock yaw, duplicate, reorder, and multi-select rows.
- Save, load, and share: Plans are stored as JSON and can be organized in folders, so you can import and export TAS files with others.
