How to reproduce

Run the following code somewhere in baritone ( I did this to manually use the movement system inside baritone from another thread ):

Movement startup = new MovementParkour(baritone, ctx.playerFeet(), 2,Direction.fromAngle(180),true);
        currentState = startup.updateState(currentState);
        currentState.setTarget(new MovementState.MovementTarget(new Rotation(0,0),false));
        while (!currentState.getStatus().equals(MovementStatus.SUCCESS) &&
                !currentState.getStatus().equals(MovementStatus.FAILED)) {
            startup.updateState(currentState);
            startup.update();
        }

And the code that causes the exception is:

    @Override
    public void updateTarget(Rotation target, boolean force) {
        this.target = target;
        if (!force) {
            double rand = Math.random() - 0.5;
            if (Math.abs(rand) < 0.1) {
                rand *= 4;
            }
    (HERE)->       this.target = new Rotation(this.target.getYaw() + (float) (rand * Baritone.settings().randomLooking113.value), this.target.getPitch());
        }
        this.force = force || !Baritone.settings().freeLook.value;
    }

The issue might be cause by initializing a variable using itself, and can be fixed through changing line 58 to:

    this.target = new Rotation(target.getYaw() + (float) (rand * Baritone.settings().randomLooking113.value), target.getPitch());

Modified settings

To get the modified settings run #modified in game

Final checklist

  • I know how to properly use check boxes
  • I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
  • I have included logs, exceptions and / or steps to reproduce the issue.
  • I have not used any OwO's or UwU's in this issue.
