[1.7.10] Key Bindings wont work

[tiffit]

Whenever I press a key in minecraft I get "Exception caught during firing event cpw.mods.fml.common.gameevent.InputEvent$KeyInputEvent@c92d089:

java.lang.NullPointerException"

 

My KeyBindings class:

public class KeyBindings extends ClientRegistry
{
public static KeyBinding GunSound;
public Minecraft mc = Minecraft.getMinecraft();

public static void init()
{
	GunSound = new KeyBinding("key.playerDeath", Keyboard.KEY_DOWN, "key.categories.playerDeath");

	ClientRegistry.registerKeyBinding(GunSound);
}

@SideOnly(Side.CLIENT)
@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event)
{
		if(GunSound.isPressed()){
			EntityPlayer player = mc.thePlayer;

			soundHandler.onEntityPlay("gun", mc.thePlayer.worldObj, mc.thePlayer, 1, 1);
					}
	}

}

Try this, worked for me!

 

Keybindings Class:

 

package com.deb.debmodularships;

import net.minecraft.client.settings.KeyBinding;

import org.lwjgl.input.Keyboard;

import cpw.mods.fml.client.registry.ClientRegistry;

public class ModularshipsKEYBINDS {
public static KeyBinding SpeedUp;

    public static void init() {
    	SpeedUp = new KeyBinding("key.SpeedUp", 201, "DEB.modularships.SpeedUp");//pg_up

        ClientRegistry.registerKeyBinding(SpeedUp);
    }
}

 

Key Event

 

package com.deb.debmodularships;

import net.minecraft.client.Minecraft;

import com.deb.debmodularships.entities.EntityShipSeat;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.InputEvent;

public class ModularshipsINPUT {

@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event) {

}
}

 

Call Keybind init method and "FMLCommonHandler.instance().bus().register(new ModularshipsINPUT());"

from ClientProxy

 

I basically just copied these from my mod, change all the names to whatever you want!

 

P.S. the Event triggers for all keys, make sure to check for the one you want!

[tiffit]

SpeedUp = new KeyBinding("HERE", 201, "HERE");

what exactly goes                  ^      and    ^

[david476]

Sorry about that!

 

you want (name, keynum, catagory)

 

name = "key.yourkeyname"

keynum = Keyboard.KEY_yourkey (this returns an int, I just used the number, it doesn't matter)

catagory = "key.categories.yourmodname" (looks like I did it wrong, oops!)

 

Check out this for more details:

http://www.minecraftforge.net/wiki/Key_Binding

[tiffit]

still keeps crashing!

 

my main class:

@Mod(modid = Main.MODID, version = Main.VERSION)
public class Main
{
    public static final String MODID = "kickback";
    public static final String VERSION = "1.0";
    
    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {    	
        Configuration config = new Configuration(event.getSuggestedConfigurationFile());
        config.load();
        Property automated = config.get(Configuration.CATEGORY_GENERAL, "automated", false, "false = manual, true = when someone dies");
        config.save();
    }
    
    @EventHandler
    public void init(FMLInitializationEvent event){
    	MinecraftForge.EVENT_BUS.register(new playerDeath());
    	FMLCommonHandler.instance().bus().register(new KeyBindings()); 
}
    

    
}

 

 

My keybindings class:

public class KeyBindings {
public static KeyBinding gunSound;

public Minecraft mc = Minecraft.getMinecraft();
EntityPlayer player = mc.thePlayer;

    public static void init() {
        gunSound = new KeyBinding("key.gunSound", Keyboard.KEY_DOWN, "key.categories.misc");

        ClientRegistry.registerKeyBinding(gunSound);
    }
    
    @SubscribeEvent
    public void onKeyInput(InputEvent.KeyInputEvent event) {
        if(KeyBindings.gunSound.isPressed())
            System.out.println("ping");
    }
}

[david476]

Could you post the crash report, it helps!

[david476]

Follow these steps:

 

Put the event in its own class

Delete "FMLCommonHandler.instance().bus().register(new KeyBindings());"

Set up proxies: http://www.minecraftforge.net/wiki/Proxies (Old but looks like mine)

Make a method in both proxy classes called KeyBindings (exactly same name and inputs if any)

Put "FMLCommonHandler.instance().bus().register(new NameOfEventClass());" and "KeyBindings.init();" into the method in the CLIENT proxy

 

If it doesn't work, make sure to send all classes and the crash report.

[knokko]

I nowhere see you calling your init() method in KeyBindings, if you don't call this method, GunSound will not be initialisated and null.

So if you use gunsound.isPressedd(), gunsound is null, so you will cause a NullPointerException.

[tiffit]

Im confused on the part where you said,

"Make a method in both proxy classes called KeyBindings (exactly same name and inputs if any)."
