[1.11.2] Server won't let me update my teleport position


Triphion

Recommended Posts

So to get rid of a misunderstanding here, i can use the item, and it does teleport me if i click on the ground or something like 5 blocks away. However if i click beyond that then i will teleport to the position im looking at but right after the server will teleport me straight back to my beginning-position. It works on singleplayer, and the raytrace is further away than 5 blocks, it's actually a raytrace distance of 22 blocks. Any help would be much appreciated. 

	@Override
	public ActionResult onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) 
	{
		if(!playerIn.world.isRemote)
		{
			RayTraceResult pos = playerIn.rayTrace(22.0D, 0.0F);
			double x = pos.getBlockPos().getX();
			double y = pos.getBlockPos().getY() + 1.0D;
			double z = pos.getBlockPos().getZ();
			playerIn.setPositionAndUpdate(x, y, z);
			worldIn.updateEntities();
			playerIn.getHeldItem(handIn).damageItem(1, playerIn);
			
			return new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
		}
		
		else if(playerIn.world.isRemote)
		{
			RayTraceResult pos = playerIn.rayTrace(22.0D, 0.0F);
			double x = pos.getBlockPos().getX();
			double y = pos.getBlockPos().getY() + 1.0D;
			double z = pos.getBlockPos().getZ();
			playerIn.setPositionAndUpdate(x, y, z);
			worldIn.updateEntities();
			playerIn.getHeldItem(handIn).damageItem(1, playerIn);
			
			return new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
		}
		
		return new ActionResult(EnumActionResult.FAIL, playerIn.getHeldItem(handIn));
	}

Because you never told the server what you were doing.

 

Remember:

The client is always a lying, cheating bastard.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Because the onItemRightClick method is only called when the player has their mouse over a block and that only happens when the block is within their reach.

I believe you are thinking of onItemUse instead here Draco.

You shouldn't be calling this.

I tried this, but now it doesn't work at all in server. Also tried with only checking if(!worldIn.isremote) but doesn't work in servers either.

Change the method Entity#setPositionAndUpdate to setPosition and use World#updateEntityWithOptionalForce wth the boolean parameter being true.

Tried it, but server won't activate my item. And if i add the "else if(worldIn.isRemote)" i'm back where i started.

This is a gyazo gif of what happens:

So i tried with console-printing and when im on the server it doesn't get called after the if(!worldIn.isRemote) check for some reason. 

	@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) 
	{
		scala.Console.print("Gets called. ");
		if (!worldIn.isRemote)
		{
			scala.Console.print("worki. ");
			
			RayTraceResult pos = playerIn.rayTrace(22.0D, 0.0F);
			double x = pos.getBlockPos().getX();
			double y = pos.getBlockPos().getY() + 1.0D;
			double z = pos.getBlockPos().getZ();
			
			if (playerIn.attemptTeleport(x, y, z)) 
			{
				scala.Console.print("Teleported. ");
				playerIn.getHeldItem(handIn).damageItem(1, playerIn);
			}
		}
		else{
		    return new ActionResult(EnumActionResult.FAIL, playerIn.getHeldItem(handIn));
		}
		
		return new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
	}

Anything that seems to doesn't work on server here? 

 

EDIT: I got a message from the server window that there's a problem with my raytracing apparently? Doesn't that get called correctly on server side, am i missing some important raytracing check for serverside?

...scala.Console????

Please set up and use a logger for your mod (An example of this is included in the example code that ships with every forge install). Try stepping through your code with the debugger

        }
        
        return new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
    }

Also, i added added a cast to the player saying it's an entitylivingbase, although the player class does extend entitylivingbase but i thought it could help just being even more specific.

[14:11:24] [Server thread/FATAL]: Error executing task

This is the error and i have no idea how to fix it. The line that is the problem is the raytracing line that i talked about but i don't know more than this. 

This is line 45:

			RayTraceResult pos = player.rayTrace(22.0D, 20.0F);

Any ideas?

I do have a logger function, but only one that gets called preinit. If i want the logger function to get called, this way of doing it does work when im on singleplayer, however in server window, the log function never gets mentioned? 

	@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) 
	{
		if (!worldIn.isRemote)
		{
			EntityLivingBase player = ((EntityLivingBase)playerIn);
			
			RayTraceResult pos = player.rayTrace(22.0D, 20.0F);
			double x = pos.getBlockPos().getX();
			double y = pos.getBlockPos().getY() + 1.0D;
			double z = pos.getBlockPos().getZ();
			Utils.getLogger().info("Raytrace: " + pos.toString().substring(5));
				
				if (player.attemptTeleport(x, y, z)) 
				{
					player.getHeldItem(handIn).damageItem(1, playerIn);
				}
			}
		else{
		    return new ActionResult(EnumActionResult.PASS, playerIn.getHeldItem(handIn));
		}
		
        return new ActionResult(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn));
	}

You're trying to call a client only function on the server.

 

@Nullable
@SideOnly(Side.CLIENT)
public RayTraceResult rayTrace(double blockReachDistance, float partialTicks)
{
    Vec3d vec3d = this.getPositionEyes(partialTicks);
    Vec3d vec3d1 = this.getLook(partialTicks);
    Vec3d vec3d2 = vec3d.addVector(vec3d1.xCoord * blockReachDistance, vec3d1.yCoord * blockReachDistance, vec3d1.zCoord * blockReachDistance);
    return this.world.rayTraceBlocks(vec3d, vec3d2, false, false, true);
}

As mentioned you are trying to call a client method. Just copy the code (and any further client-only code involved) into your own method. You'll also need to modify the part regarding the reach distance. Overall ray-tracing is pretty simple concept so you should be able to implement your own version.

Worked for me. A massive thanks to everyone who helped me! :D
