Hi,

i have a problem with my teleporter. It's an item, that places a block and if clicked on a  nother block of same type it will bound both together and teleport the player if he collides with one of them.

Easy said: 2 mirrors, that will be bound together and teleport the player between both.

It's working in creative mode, but in survival mode i allways get : Player moved wrongly!

 

This is the item 

package thewizardmod.mirror;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.EnumActionResult;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.EnumHand;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.RayTraceResult;
import net.minecraft.util.text.TextComponentString;
import net.minecraft.world.World;
import thewizardmod.Util.RayTrace;

public class ItemMirror extends Item
{
	
  public ItemMirror()
  {
    final int MAXIMUM_NUMBER_IN_STACK = 1;
    this.setMaxStackSize(MAXIMUM_NUMBER_IN_STACK);

    this.setCreativeTab(CreativeTabs.MISC);   // the item will appear on the Miscellaneous tab in creative
  }

  @Override
	public EnumActionResult onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) {
	    
		RayTraceResult p = RayTrace.rayTraceBlocksAndEntities(worldIn, 5, playerIn);

		BlockPos newpos;
		if(p != null)
		{
		  newpos = p.getBlockPos().offset(facing);
		
		  if(worldIn.getBlockState(p.getBlockPos()).getBlock() != StartupCommon.mirror)
		  {
			  if(facing == EnumFacing.NORTH || facing == EnumFacing.SOUTH || facing == EnumFacing.WEST || facing == EnumFacing.EAST)
			  {
				  worldIn.setBlockState(newpos, StartupCommon.mirror.getDefaultState().withProperty(Mirror.PROPERTYFACING, facing.getOpposite()));
				  NBTTagCompound nbtTagCompound = stack.getTagCompound();
				  if (nbtTagCompound != null && nbtTagCompound.hasKey("Bound") && nbtTagCompound.getBoolean("Bound") == true ) 
				  {
					  TileEntity tileEntity = worldIn.getTileEntity(newpos);
					  if (tileEntity instanceof TileEntityBlockMirror) 
					  {
						  TileEntityBlockMirror te = (TileEntityBlockMirror) tileEntity;
						  double x = nbtTagCompound.getDouble("X");
						  double y = nbtTagCompound.getDouble("Y");
						  double z = nbtTagCompound.getDouble("Z");
						  te.setPosition(x, y, z);

						  double oldX = nbtTagCompound.getDouble("oldTeX");
						  double oldY = nbtTagCompound.getDouble("oldTeY");
						  double oldZ = nbtTagCompound.getDouble("oldTeZ");
						  BlockPos oldTePos = new BlockPos(oldX, oldY, oldZ);
						  TileEntity tileEntityOld = worldIn.getTileEntity(oldTePos);
						  if (tileEntity instanceof TileEntityBlockMirror) 
						  {
							  TileEntityBlockMirror te2 = (TileEntityBlockMirror) tileEntityOld;
							  BlockPos targetPos = newpos.offset(facing);
							  te2.setPosition(targetPos.getX(), targetPos.getY(), targetPos.getZ());
						  }						  
					  }
					  
				  }
				  stack.stackSize--;
			  }
		  }
		  else
		  {
		      NBTTagCompound nbt;
		      if (stack.hasTagCompound())
		      {
		          nbt = stack.getTagCompound();
		      }
		      else
		      {
		          nbt = new NBTTagCompound();
		      }
		      BlockPos targetPos = newpos.offset(facing);
		      nbt.setBoolean("Bound", true);
		      nbt.setDouble("X", targetPos.getX());
		      nbt.setDouble("Y", targetPos.getY());
		      nbt.setDouble("Z", targetPos.getZ());
		      nbt.setDouble("oldTeX", p.getBlockPos().getX());
		      nbt.setDouble("oldTeY", p.getBlockPos().getY());
		      nbt.setDouble("oldTeZ", p.getBlockPos().getZ());
		      stack.setTagCompound(nbt);
		      if (worldIn.isRemote) {  // only on the client side, else you will get two messages..
		          playerIn.addChatComponentMessage(new TextComponentString("Mirror bound!"));
		        }
		  }
		}
	  return super.onItemUse(stack, playerIn, worldIn, pos, hand, facing, hitX, hitY, hitZ);
	}
}

And the tile entity

public class TileEntityBlockMirror extends TileEntity{

	public int facing;
	public double posX, posY, posZ;
	
	public int getFacing()
	{
		return facing;
	}
	
	public void setFacing(int facing)
	{
		this.facing = facing;
		markDirty();
	}
	
	public void setPosition(double x, double y, double z)

	}

		super.writeToNBT(tag);
		tag.setInteger("facing", facing);

	}

	@Override
	public void readFromNBT(NBTTagCompound tag) {

	}
	
	@Override
	public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity pkt) {

	@Override

	}

	
	
}

 

Possible something simple in the teleportation, i can't see.

try "setPositionAndUpdate(x,y,z)" or "setPositionAndRotation(x,y,z,yaw,pitch)"

also put "System.out.println("tpmirror - " + entityPlayerMP.getName()")"

and check the log for "tpmirror - Dustpuppy"

Also, I have been having a problem where "SideOnly(Side.SERVER)" does not work, you already have the Server Player check so don't add it if you have it and try again after you try the above solutions.

That does not do what you think it does.

 

 

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.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

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

I know I have collision code somewhere, lemme find it...

found it: 

public void onEntityCollidedWithBlock(World w, BlockPos pos, IBlockState state, Entity entityIn) {
	...
}

paste this into your BLOCK, you have the world and blockpos, so you can find the TE.

Get rid of your other teleportation code.

Ok,

this will work now. Just if both blocks are to near and player get bounced between them, i am in trouble. 

				if(worldIn.isRemote)
			        if (entityIn instanceof EntityPlayer) { // should be an EntityPlayerMP; check first just to be sure to avoid crash
			          EntityPlayer entityPlayer = (EntityPlayer)entityIn;
			          entityPlayer.setPositionAndRotation(x, y, z, entityPlayer.rotationYaw, entityPlayer.rotationPitch);
			        }

 

Have taken out the sounds, because they where confusing me. Will put in later on again.

spit the player out about a block infront of the mirror, just outside of the collision box.

I do. If the second mirror then is near enough to split the player into it, he bounce that fast, that he will hang between both and the console will be flooded with warnings about wrongly moving.

I have to check, that gamers will not place the mirrors without a big enough gap between.

try moving your mirrors farther apart.

I do it, but you know the playing kids. If they find out, that it is possible to put two mirrors to near to each other, they will do.

So, i make an if statement, to prevent this. ¬¬
