[1.7.2] Dimensional teleporting, without the portals

whiskeyfur · April 22, 2014

Gettin' a little tired of putting nether portals all over the place in the game when trying to /home. Since forgeessentials hasn't been worked on for a while I'm trying to code my own.

What is the best way to move an entity from one world to an another without creating those obsidian gateways?

entity.travelToDimension(dimensionID); (-1 for nether)

although this spawn a portal in the nether.

Unfortuntely I'm trying to avoid those portal all together. The code I'm doing this for is so the player can /home, do what he needs to, then /back to where he went.

In most cases, he certainly didn't have a nether portal near him when he left that dimension so... yea.

Problem, sry don't know how to fix, maybe check i WorldProvider for something useful.

You could do what Godis_apan said and add code to delete the portal as soon as it spawns, not an elegant solution but it might work

Godis_apan · April 22, 2014

That's smart, when the teleport happens just make a three for loops increasing the x, y, z like this.


for (int i = player.posX - 5; i < player.posX + 5; i++)
{
    for (int j = player.posY - 5; j < player.posX + 5; j++)
    { 
        for (int k = player.posZ - 5; k < player.posX + 5; k++)
        { 
               if (world.getBlock(i, j k) == Blocks.obsidian || world.getBlock(i, j k) == Blocks.portal)
               {
                       world.setBlockToAir(i, j, k);   
               }
        }
    }
}

Something like that.

I understand that method would work, though I'm not a real big fan of it because it feels more like a hack than a solution. For example, if they happen to be standing on obsidian, like a lava lake turned obsidian from a firestone, then this'll end up deleting obsidian blocks that didn't come from a portal.

I'm looking at possibly grabbing the worldserver for their source and destination worlds and telling them to remove and add the player respectively, then update their position. I don't think this'll work but it's worth a shot.

//WorldServer start = DimensionManager.getWorld(plyr.dimension);
//start.getPlayerManager().removePlayer(plyr);

WorldServer overworld = DimensionManager.getWorld(0);
overworld.getPlayerManager().addPlayer(plyr);

ChunkCoordinates c = overworld.getSpawnPoint();
plyr.setPositionAndUpdate(c.posX, c.posY, c.posZ);

Edit: This was a fail.

Create your own teleported class and a command to call it. You will need to specify where to go in the destination dimension somehow.

Do you have some example code to show this? I've yet to see a way to get around making a portal in game without effectively recreating the CommandServerTP class.

delpi · April 23, 2014

I can share one tonight.

The basics are you need your own command. Assuming you know how to do that.

From it you call your teleported code. The trick is to override the methods in such a way it only does what you want.

whiskeyfur · April 23, 2014

That would be extremely helpful Delpi, thank you. I have the commands ready to go aside from that one piece.

jabelar · April 23, 2014

without effectively recreating the CommandServerTP class.

What's wrong with that? That is probably the way you would want to do it, and I think delpi is proposing to give you such an example. Logically it sounds like what you want -- a custom command that teleports.

Here is something that works for me. I've done it different ways, but you should be able to modify this to suit your purposes.

if (world_property != null) {

dx = world_property.spawn_x();

dy = world_property.spawn_y();

dz = world_property.spawn_z();

}

// check for zeros

if (dx == 0 && dy == 0 && dz == 0) {

// Set height to something big

dy = 250;

// Drop down until find solid

while (world.getBlock((int) dx, (int) dy - 1, (int) dz).equals(Blocks.air) && dy > 0) {

dy--;

}

// Last check if dy == 0

if (dy == 0) {

dy = 128;

}

// Offset locations for accuracy

dx = dx + 0.5d;

dy = dy + 1.0d;

dz = dz + 0.5d;

entity.setPosition(dx, dy, dz);

// Freeze motion

entity.motionX = entity.motionY = entity.motionZ = 0.0D;

entity.setPosition(dx, dy, dz); // silly to do this multiple time,s but it kept offseting entity until this was done

// Set Dimension

if (entity.worldObj.provider.dimensionId != world.provider.dimensionId) {

playerMP.mcServer.getConfigurationManager().transferPlayerToDimension(playerMP, world.provider.dimensionId, this);

}

entity.setPosition(dx, dy, dz); // silly to do this multiple time,s but it kept offseting entity until this was done

// instance.logger.log(Level.INFO, "Teleported to " + world_name + ":" + dx + "/" + dy + "/" + dz);

}

// Override Default BS

@Override

public boolean placeInExistingPortal(Entity par1Entity, double par2, double par4, double par6, float par8)

{

return false;

}

@Override

public void removeStalePortalLocations(long par1)

{

}

@Override

public void placeInPortal(Entity par1Entity, double par2, double par4, double par6, float par8)

{

}

Then setup a custom command to call it with something similar to this.

new MyTeleporter(minecraftserver.worldServerForDimension(world.provider.dimensionId)).teleport(target, world);

Let me know how it goes.
