Well i try to spawn a explosion on the coardinates of the player.. that works pretty well with this:
 

player.world.createExplosion(player, player.getPosition().getX(), player.getPosition().getY() + 1, player.getPosition().getZ(), (float) (level * 0.1), true);

*i am spawning it with a keybind*
but that wont change if the player rotates ... what i want it to do .. i want it to be always spawned at the right side of the player inside of his right hand ..

taking out useless stuff

Yaw and pitch are angles for rotation. Use Entity#getLookVec to get the vector of where the player is looking to then rotate and translate it until you get the desired result.

thanks i will try that

@V0idWa1k3r
thanks that worked!

ahh nooo :I .. i think this would not be any releated to this anymore
but i noticed i am spawning the explosion client side and not server side .. how would spawn it server sided?

Detect the key press client-side then send a packet to the server and spawn the explosion.

thanks .. funny enough i already have a packets .. but i forgot that i could use them to do that

i got the packets working.. now everything or the explosions is server sided what is great.. but the explosion does not do damage...

serverPlayer.getServerWorld().createExplosion(serverPlayer, serverPlayer.lastTickPosX + serverPlayer.getLookVec().x , serverPlayer.lastTickPosY + 1, serverPlayer.lastTickPosZ + serverPlayer.getLookVec().z , (float) (amount), true);

is this the right way to do it? (this is in my packet handler class... the packet will send the amount of power that is being used)

still not sure about that .. also my explosion still does no damage .... (it should do damage to the entities not the player)

Why are you using lastTickPos insread of pos?

As long as you pass your actions to a server thread this is the correct way to do this.

Show more of your code preferrably as a git repository so I can debug it myself.

oh  that was just me trying .. i should change that..

i think i am doing that ...
and i don't run a git on it right now :I .. but i can give you some more code

Here some more code:
Message Handler:

public class MyMessageHandler implements IMessageHandler<MessageExplosion, IMessage> {


	  @Override 
	  public IMessage onMessage(MessageExplosion message, MessageContext ctx) {

		EntityPlayerMP serverPlayer = ctx.getServerHandler().player;
	    
	    float amount = message.power;
	    serverPlayer.getServerWorld().addScheduledTask(() -> {
	      serverPlayer.getServerWorld().createExplosion(serverPlayer, serverPlayer.lastTickPosX + serverPlayer.getLookVec().x , serverPlayer.lastTickPosY + 1, serverPlayer.lastTickPosZ + serverPlayer.getLookVec().z , (float) (amount), true);
	      
	    });
	    return null;
	  }
	  
}

Message:

public class MessageExplosion implements IMessage {
	
	  public MessageExplosion() {}

	
	  public MessageExplosion(float power) {
	    this.power = power;

	  }
	  
	  float power;
	  EntityPlayer player;
	  
	  @Override public void toBytes(ByteBuf buf) {
	    buf.writeFloat(power);
	  }

	  @Override public void fromBytes(ByteBuf buf) {
	    power = buf.readFloat();
	  }
	  
	  public float getamount() {
		  return power;
	  }
}

Here is what class i am using to spawn the explosion

public class QuirkExplosive extends Quirk {
	
	private static EntityPlayer p;
	
	public QuirkExplosive() {
		super("explosive");
		setMaxCooldown(2000);
		setLevelMinimum(100);
		setLevelFactor(5);
		setMaxActivatedTime(1);
		setLevelUp(new LevelUp(0, 0.99));
		setXpPerTick(1/20);
	}

	@Override
	public void onPlayerUse(EntityPlayer player) {
		p = player;
		if(aviable) {
			BnHA.proxy.simpleNetworkWrapper.sendToServer(new MessageExplosion(level * 0.1F));
			aviable = false;
			xp += level * 2.75;
		}
	}

	@SubscribeEvent
	public static void tick(ServerTickEvent event) {
		if(!aviable) {
			cooldown++;
			if(cooldown >= maxCooldown) {
				aviable = true;
				cooldown = 0;
			}
		}
		if(xp >= nextXp) {
			level++;
			nextXp = xp * levelFactor;
			if(p != null) {
				p.sendMessage(new TextComponentString(TextFormatting.AQUA + "Level Up"));
				p.sendMessage(new TextComponentString(TextFormatting.AQUA + "Your now level " + level));
			}
			maxCooldown *= levelUp.getCooldownMultiplier();
		}
	}

	
}

@V0idWa1k3r if the superclass is relevant i can send it too

You do not need to cast a float to a float.

Why is your networkwrapper in your proxy? And this looks like a Code-style Issue #1 to me.

level * 0.1F

I think that your issue is here. Explosions with a very low power value will not damage entities.

@V0idWa1k3r ... well i have overtaken the mod i am working on but i knew such thing as a "common" proxy should not exist aka. that what i were doing is wrong.. but just ignored that because it worked fine for now (right now i just want something running good XD) i will fix that in a second ..

i wasn't sure about that .. but this actually could it be XD.. i will now debug my code and write another reply .. if changing the power worked

yup .. that was it .. now just out of curiousity ... is there a way to turn off explosion damage and just do damage to entities?

The last parameter of World#createExplosion is a boolean controlling whether the explosion damages terrain.
