I made a Container, but it does not do what i want it to do.

 

When I place an item in a slot, quit the world and then load the world, The item in that slot is gone.

It will not take it either. When I place the item inside, The cursor will still have the item, but the slot too.

 

Container and Gui are not different then my other containers and GUIs, those work perfectly!

Only the Guihandler is slightly different.

 

btw, it is a container for a mob.

 

public Object getServerGuiElement(int id, EntityPlayer player, World world, int x, int y, int z) { 
	switch(id){
	case 6:
		EntityTest test = getUnitMouseOver2(5, 0, player);
		System.out.println("calling Container");
		return new ContainerTest(player.inventory, test.inventory, test);
	}

	return null;
}

@Override
public Object getClientGuiElement(int id, EntityPlayer player, World world, int x, int y, int z) {
	switch(id){
	case 6:
		EntityTest test = getUnitMouseOver2(5, 0, player);
		System.out.println("calling Gui");
		return new GuiTest(player.inventory, test.inventory, test);
	}

	return null;

}

public static MovingObjectPosition getMouseOver(double distance, float f)
    {
    	Minecraft mc = FMLClientHandler.instance().getClient();
    	
        if (mc.renderViewEntity != null)
        {
            if (mc.theWorld != null)
            {
                double var2 = distance;
                MovingObjectPosition mouseOver = mc.renderViewEntity.rayTrace(var2, f);
                Vec3 var6 = mc.renderViewEntity.getPosition(f);

                double var4 = var2;

                        {

                            }
                        }

                }

                {
                   mouseOver = new MovingObjectPosition(pointedEntity);
                }

    		return (EntityTest) mouseOver.entityHit;
    	}else
    		return null;

Interact part of the entity:

public boolean interact(EntityPlayer par1EntityPlayer)
{
	if(par1EntityPlayer.isSneaking() && !this.worldObj.isRemote) {
		par1EntityPlayer.openGui(Core.instance, 6, par1EntityPlayer.worldObj, (int)par1EntityPlayer.posX, (int)par1EntityPlayer.posY, (int)par1EntityPlayer.posZ);
	}
	return super.interact(par1EntityPlayer);
}

Broken? How do you mean?

I can just use it. When the outcome entity of the methode is not null, it'll print out text. and it did.

Why is it broken?

 

Okay, so I saw your tutorial of the simple network wrapper.  http://www.minecraftforge.net/forum/index.php/topic,20135.0.html

Can I use this to get the container to work?

What kind of packets do I need to use?

 

Okay, I will say ´this´ in the interact methode.

I know how to get the entityID.

But how do I pass the entityID?

Now, I have a very diferent problem.

seems like my EntityTest does not like the world.getEntitybyID(int i)

 

My other, let's say 'real' entity, likes it a lot.

Thanks for helping!
