Modify the keybindings

I'm going to write a potion that perform like confusion. That I want to swap the client's keybindings that when he press "w" and want to move forward and then he actually press "s" that he move backward.

I'm searching for the code in the src but get confusion :'( ....

Could someone point out the code I'm looking for? Or some simple idea about that?

Hi

This is some background info that might be useful...

http://greyminecraftcoder.blogspot.com.au/2013/10/user-input.html

EntityPlayerSP.movementInput uses the method MovementInputFromOptions.updatePlayerMoveState(), so if you create your own class ConfusedMovementInput extends MovementInputFromOptions, and store it in EntityPlayerSP.movementInput, you can turn confusion on or off

eg

public class ConfusedMovementInput extends MovementInputFromOptions {

public ConfusedMovementInput(MovementInput interceptedMovementInput) {
underlyingMovementInput = interceptedMovementInput;
}

@Override
public void updatePlayerMoveState() {
  underlyingMovementInput.updatedPlayerMoveState();

        this.jump = underlyingMovementInput.jump;
        this.sneak = underlyingMovementInput.sneak;

        if (!confused) {
          this.moveStrafe = underlyingMovementInput.moveStrafe;
          this.moveForward = underlyingMovementInput.moveForward;
        } else {
            // swap moveStrafe, moveForward, or make them negative, etc
        }

}

public void setConfusion(boolean newConfused) {
  confused = newConfused;
}

protected MovementInput underlyingMovementInput;
private boolean confused = false;

}

And somewhere else in your code you execute

ConfusedMovementInput myInput = new ConfusedMovementInput(entityPlayerSP.movementInput);

entityPlayerSP.movementInput =myInput;

and then myInput.setConfusion(true/false) to turn confusion on or off.

You can access entityPlayerSP from

Minecraft.getMinecraft().thePlayer

I haven't tried to execute this code, but you get the idea?  The mix of composition and inheritance is a bit clumsy because of the private GameSettings but it should still work.  I have used something very similar for other keybindings (https://gist.github.com/TheGreyGhost/7033821) and it worked great.

Looks like... *puts on glasses* ... you are confused.

I've tried your code. But it seems not working.

I try to replace the movement input while the player join the world. And as the log I see that I replace it successfully. But the updatePlayerMoveState() of the new class did not invoke. dont know why.

I make a small change the it inhert from MovementInput, not MovementInputFromOptions. dont know if that is related.

Hi

Interesting.  I tried it in my mod and it works fine.  When I'm holding an item, left and right are swapped.  When I'm not holding an item, left and right are normal.

Hi.

I've try you code and it works.

I replace it in the event EntityJoinWorldEvent. May be it's before the initialization of the player's movementInput. It seems that I should go to see how MC runs.

Anyway it works, thx.

no worries, you're welcome, it was fun to try and figure it out :-)
