Fails at parkour

[popey456963]

If I wanted to contribute the ability to "parkour" to this module, would you be able to point me in the correct direction to do so? What would it take in order to allow the program to make jumps?

There are 2 steps for adding special moves:

• Make the pathfinder aware that move is valid (and assign it a cost to compare it to other possible moves)
• Implement a control algorithm to execute that move (or more likely modify the existing control algorithm)

First step is done by generating the move in the getNeighbors function: https://github.com/PrismarineJS/mineflayer-pathfinder/blob/master/lib/movements.js#L333

Second step is done here https://github.com/PrismarineJS/mineflayer-pathfinder/blob/master/index.js#L327 by adjusting the control states and heading direction.

At the moment, only basic parkour is implemented (1 blocks gaps, towering,..). It would be interesting to add more complex movements (>1 block jumps, fall in water (place bucket), ladders and vines).

So, not sure if this deserves a new issue or is under this catergory, but sometimes I see the bot failing at making a simple single block horizontal jump, e.g:

https://v2.femto.pw/d4wy.mp4

It doesn't always happen, take this similary single block jump from standing:

https://v2.femto.pw/4upj.mp4

Here the bot succeeds on the first jump, but then fails the second:

https://v2.femto.pw/m5iw.mp4

All of these are reproducible failures, given the same environment.

Yeah, that says the control algorithm need to be improved. Feel free to play with it.
