proper dimension teleportation?

[memcallen]

I created a custom dimension that works fine. currently it's just a copy of the overworld.

 

I need help with teleportation to the dimension, currently what I'm doing is

player.dimension=myDimensionID;

 

this works, but it doesn't teleport the player and you collide with invisible blocks which I think are from my custom dimension.

I'm pretty sure it's a client-server sync issue but I can't solve it.

Hi

 

Teleportation to another dimension is a bit more complicated than that 

 

There are a couple of other topics on this forum lately that are talking about the same thing which might be of help.  Alternatively you could dig through the portal code or the teleport player command for inspiration.

yeah I kind of figured that, I was reading the other topic on the same-ish subject and I couldn't understand the teleportation code at all. unfortunately I also have no idea how to unpack the minecraft files.

Hi

 

if you used setupDecompWorkspace, they are there.  Look under reference libraries, there is a library there called forgeSrc-{version info here} or something similar.  Open that and you'll see the vanilla classes.

 

Alternatively, you can search for classes by name in all libraries (ctrl N in IntelliJ, don't know in Eclipse)

Ok awesome, I never knew about that. I thought you had to do some crazy thing to decompile it all...

Looking at the the entities code, it seems like you should be able to simple call Entity#travelToDimension(int dimensionID).

[memcallen]

I just tested travelToDimension, it sent me to the nether even though I put in the correct ID.

(bump) I've tried multiple things to teleport the player, all of them either crash you or send you to the nether and I have no idea why.

Here is my teleporter code hopefully it will help you.

 

First you need to create a teleporter class that extends Teleporter

 

import net.minecraft.entity.Entity;
import net.minecraft.world.Teleporter;
import net.minecraft.world.WorldServer;

public class CustomTeleporter extends Teleporter
{
private double tX;
private double tY;
private double tZ;
private float yaw;
private float pitch;

public CustomTeleporter(WorldServer worldServer, double tX, double tY, double tZ, float yaw, float pitch) {
	super(worldServer);

	this.tX = tX;
	this.tY = tY;
	this.tZ = tZ;
	this.yaw = yaw;
	this.pitch = pitch;
}

@Override
public void placeInPortal(Entity entity, double x, double y, double z, float r)
{
	entity.setLocationAndAngles(this.tX, this.tY, this.tZ, this.yaw, this.pitch);
}

@Override
public void removeStalePortalLocations(long par1)
{
}

@Override
public boolean placeInExistingPortal(Entity par1Entity, double par2, double par4, double par6, float par8)
{
	return false;
}
}

 

you will want to make some changes to this because this is the class that would normally generate or place the player in an existing nether portal but i have that disabled because i am using it as a telepotrer that the player has to bind to a location and there are no portals involved. in your case you need that because the player is placed in the world before the world is actually generated so it is possible for the player to fall out of the world. To figure it out just take a look at the Teleporter class that this extends.

 

 

Then you just need you just need something like the following to use it.

 

public static void teleport(EntityPlayer player, double x, double y, double z, float yaw, float pitch, int dim)
{
	if (player instanceof EntityPlayerMP)
	{
		EntityPlayerMP thePlayer = (EntityPlayerMP) player;

		if (thePlayer.dimension == dim)
		{
			player.setLocationAndAngles(x, y, z, yaw, pitch);
			player.setPositionAndUpdate(x, y, z);
		} else
		{
			if (thePlayer.isRiding())
				thePlayer.dismountEntity(thePlayer.ridingEntity);
			thePlayer.mcServer.getConfigurationManager().transferPlayerToDimension(thePlayer, dim, new CustomTeleporter(thePlayer.mcServer.worldServerForDimension(dim), x, y, z, yaw, pitch));
		}
	}
}

Thanks it works, sometimes the overworld doesn't render properly, but other than that it works fine.

Really? i was having that problem in 1.7.2 whenever i teleported from the end but it seemed to be fixed in 1.7.10... if it is happening when you teleport from the end i fixed it by running

thePlayer.mcServer.getConfigurationManager().transferPlayerToDimension(thePlayer, dim, new CustomTeleporter(thePlayer.mcServer.worldServerForDimension(dim), x, y, z, yaw, pitch));

 

twice if the player was in the end.

[memcallen]

For me, it was when I teleported to the nether, but I teleported under the world somehow. And when I teleported back to the overworld, it just didn't render.

[brandon3055]

If you use that code to teleport to a location that has not yet been generated it places you in the world before the world is actually generated so it is possible to fall out of the world. Look at the vanilla Teleporter class and you should be able to figure out how to fix that (that is one of the reasons for the nether portal)
