Here is the method:

@Override
public void onKeyPress(EntityPlayer player) {
	if(!player.worldObj.isRemote){
		EntityArrow arrow = new EntityArrow(player.worldObj, player, 2);
		player.worldObj.spawnEntityInWorld(arrow);
	}

}

This method is called by my KeyEventHandler which provides an EntityPlayerMP for the player. What am I doing wrong?

Ok I have a key handler that sends a packet to the server and the server receives that packet and calls the onKeyPress method. This keyPress method is part of the module classes we were talking about earlier

Ok did some testing it turns out that when I press the key (only once) the method is called a LOT and keeps getting called over and over. What could make this happen?

Hard to say without seeing your code, but I bet you're doing something like setting a field saying the key was pressed, then sending a packet as long as that is true.

What are you using to handle key presses? KeyInputEvent or one of the TickEvents? Show your whole class (or at least every piece of it related to handling keys) and any related classes.

Depending on what keyboard event your listening to, you're likely asking

isKeyDown(key)

which will be true for the entire duration that the key is pressed. Which as the code runs 60+ times a second* and a press lasts a tenth of a second...that's at least 6 calls.

*Pretty much as fast as the program runs, not tied to game ticks in any way.

Code:

package com.apmods.hta.handler;

import com.apmods.hta.key.HTAKeys;
import com.apmods.hta.network.AttackKeyPackage;
import com.apmods.hta.network.HTANetwork;

import net.minecraft.client.Minecraft;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.InputEvent.KeyInputEvent;

public class HTAKeyHandler {
@SubscribeEvent
public void keyDown(KeyInputEvent event){
	if(HTAKeys.attack1.isPressed()){
		if(Minecraft.getMinecraft().inGameHasFocus){
			HTANetwork.net.sendToServer(new AttackKeyPackage.KeyMessage(1));
		}
	}
	else if(HTAKeys.attack2.isPressed()){
		if(Minecraft.getMinecraft().inGameHasFocus){
			HTANetwork.net.sendToServer(new AttackKeyPackage.KeyMessage(2));
		}
	}
}
}

And when I press it and let go of the key, it just keeps calling the method

coolAlias · November 17, 2015

KeyInputEvent fires both when a key is pressed and when it is released, AND it fires for every single key on the keyboard, not just ones you may want to listen to.

You need to check Keyboard.getEventKey() and compare it to the keyCodes of your KeyBindings, and also check Keyboard.getEventState() which is true when the key is pressed.

Asweez · November 17, 2015

Ok this is really weird. When I press the key, even with your code:

if(Keyboard.getEventKey() == HTAKeys.attack1.getKeyCode() && Keyboard.getEventKeyState()){
		if(Minecraft.getMinecraft().inGameHasFocus){
			HTANetwork.net.sendToServer(new AttackKeyPackage.KeyMessage(1));
		}
	}

It will constantly put out "key pressed" in the console, even when I quit the world it keeps going. What is going on?

coolAlias · November 17, 2015

What are you doing server side? You really need to show ALL of your code that is related to the problem, otherwise we're going to go back and forth and back and forth, and that gets really tiresome.

SHOW YOUR CODE.

Oh wow all it was was that there was a for loop that was making it run multiple times. My bad. Thank you for helping, though.
