Basically, I need to access an instance of player to change motionX, motionY, etc. How would I reference the main, or the being controlled instance of Player?

Where are you trying to do this?

OK, basically, I need to change the player's motionX and motionY. How do I do this?

Basically:

player.motionX = someValue;

player.motionZ = someValue;

 

It would help if you provided some context for what you are trying to do. When, exactly, do you need to change the player's motion?

I'm trying to call it within a method:

 

public void roll(Player player) {

	player.motionX = 10;

}

 

I just need to know what to put in the parameter for player when I'm referencing it.

It's triggered by a keystroke in onPlayerTick.

 

You need packets.

You sure? I did it with onUpdate before in a class that extends Item without packets.

Suppose I was running it without using keys, how would I do it?

I'd use a tick handler, not sure which one, though. I would assume server, though, correct?

 

(Of course I would use an if inside of the method)

My main question is what instance of player do I refer to to change motionX and motionY. I still need to know that to finish.

If you're sending packets to the server (which you should be) then the one you modify is the one that sent the packet.
