Teleporting a Player Within the same Dimension

Having a little trouble with this; getting some weird behavior.

 

If I trigger the teleport on the server side only (using Entity#setPosition) the player never moves.

If I trigger the teleport on the client only, they end up at the build height (and in an unloaded chunk, at 0,0 because the client doesn't know what the destination should be).

If I trigger the teleport on both I get even weirder behavior:

 

First, realize that a map is the item used to determine the destination coordinates (i.e. teleport to map center).  On a default zoom map, I get this:

If the player is not on the map, teleport works as expected.

If the player is on the map, teleport goes to 0,255,0 (in air, due to the loop direction looking for the first block that can see the sky).

 

WTF?

 

Here's the code, on a custom entity:

 

public boolean interact(EntityPlayer player) {
    	ItemStack var1 = player.getCurrentEquippedItem();
    	if (var1 != null) {
    		if(player.inventory.hasItem(Item.enderPearl.itemID)) {
    			if(var1.itemID == Item.map.itemID) {
    				ItemMap m = (ItemMap)var1.getItem();
    				MapData d = m.getMapData(var1, worldObj);
    				if(worldObj.provider.dimensionId == d.dimension) {
    					player.inventory.consumeInventoryItem(Item.enderPearl.itemID);
    				int px = d.xCenter;
    				int pz = d.zCenter;
    				System.out.println("Center: " + px + "," + pz);//on server prints map center.  on client prints "0,0"
    				int py;
    				for(py = 50; py < 256 && !worldObj.canBlockSeeTheSky(px, py, pz); py++) {
    					;
    				}
    				player.setPosition(px, py, pz);
    				this.setPosition(px, py, pz);
    				}
    			}
    		}
    	}
    	return false;
    }

 

Most times the entity itself does not teleport either.  It simply ceases to exist as far as I can tell.

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.

DO NOT PM ME WITH PROBLEMS. No help will be given.
