I have tried in vain to teleport a player within the same Dimension when they collide with a block with no collision. In creative mode, it works flawlessly, but in singleplayer I keep getting this error: 

[01:50:38] [Server thread/WARN] [minecraft/ServerPlayNetHandler]: TheCosmicNebula_ moved wrongly!

I have tried many methods, from many classes that teleport. I can use

ServerPlayerEntity.changeDimension()

However it causes massive lag because it is repeating the same code with all of the blocks.

 

Any help would be appreciated, i'm pulling my hair out!

Issue was Solved.

show more of your code

Here is where I call the teleport:

TileEntityPortal

	public void entityInside(BlockState stateIn, World worldIn, BlockPos posIn, Entity entityIn) {
		if (!entityIn.isPassenger() && !entityIn.isVehicle() && entityIn.canChangeDimensions()) {
			if (!this.dimension.getNamespace().isBlank() && !this.dimension.getPath().isBlank()) {
				if (this.teleport_pos.getPos() != BlockPos.ZERO) {
					
					if (entityIn instanceof ServerPlayerEntity) {
						ServerPlayerEntity playerIn = (ServerPlayerEntity) entityIn;
						
						BlockPos targetPos = this.getTeleportPos();
						float yaw = this.teleport_pos.getYaw();
						float pitch = this.teleport_pos.getPitch();
						
						CosmosTeleporter teleporter = CosmosTeleporter.createTeleporter(this.getDimension(), targetPos, yaw, pitch, true, false, true);
						CosmosTeleportCore.shiftPlayerToDimension(playerIn, teleporter, null);
					}
				}
			}
		}
	}

 

Here is my ITeleporter:

As you can see, I have tried many variations on 

ServerPlayerEntity.teleport()

 

And I cannot just pull the 

ServerPlayerEntity.changeDimension()

method because it uses variables that are private.

When teleporting within the same dimension no ITeleporter is necessary. Simply call ServerPlayerNetHandler#teleport with the target coordinates (this is what /teleport does).

When teleporting across dimensions you can use ServerPlayerNetHandler#teleportTo to just do a direct teleport, without any dimension change effects. To have those you need to call ServerPlayerEntity#changeDimension with a custom teleporter. There is no reason to copy any of this code.

 

I have tried this:

playerIn.connection.teleport(targetPos.getX(), targetPos.getY(), targetPos.getZ(), yaw, pitch);

And I am still getting the same error:

[12:42:47] [Server thread/WARN] [minecraft/ServerPlayNetHandler]: TheCosmicNebula_ moved wrongly!

Show that code, specifically where exactly you are calling it.

					float yaw = this.teleport_pos.getYaw();

					if (entityIn instanceof ServerPlayerEntity) {

Are you sure you are only calling that once and not repeatedly every tick for the same entity?

 

I'm using vanilla code to create the Portal Blocks, so when the player is trying to enter the Portal it could be calling the code multiple times, but it works in Creative mode and when travelling across dimensions. Just not the same dimension in survival mode.

 

Here is where I pass the method to my TileEntity:

BlockPortal:

Spoiler

	@Override
	public void entityInside(BlockState stateIn, World worldIn, BlockPos posIn, Entity entityIn) {
		if (!worldIn.isClientSide) {
			TileEntity tile = worldIn.getBlockEntity(posIn);
			
			if (tile != null && tile instanceof TileEntityPortal) {
				((TileEntityPortal) tile).entityInside(stateIn, worldIn, posIn, entityIn);
			}
		}
	}

I have tried with just a single Portal block, the same Issue ocurrs.

I have managed to get it working in survival. It's still behaving oddly, but it does work now. Thanks for the help!
