Frost Dragon Empire

How do I drop items into the world? I looked inside of world class and couldn't find it.

That worked, also I was digging through the spawner code, and found this works just fine. (Changing how I am doing things a little, so I may use all living entities instead of just villagers.) List<Entity> villagers = world.getEntitiesWithinAABB(LivingEntity.class, axis);

Oh ok, I get it.

I think I am miss understanding something here. This is my code: AxisAlignedBB axis = new AxisAlignedBB(pos.getX(), pos.getY(), pos.getZ(), pos.getX(), pos.getY()+3, pos.getZ()); List<Entity> villagers = world.getEntitiesWithinAABB(AbstractVillagerEntity.class, axis, entity -> true); System.out.println("Villager Count " + villagers.size()); and when I run this, it's not finding any villagers, even though they are right on top of the block. <edit> the variable pos is the block position. I check it to make sure something weird wasn't happening to the variable.

I have a tile entity, and I need to access the villager who is standing on top of the tile, or maybe all the villagers standing on top of the tile. How can I do this? This function looks like the right one to use, just not sure what to put for the predicate. public <T extends Entity> List<T> getEntitiesWithinAABB(Class<? extends T> clazz, AxisAlignedBB aabb, @Nullable Predicate<? super T> filter)

if you change the biome, for instance, then delete all the chunk(if it was possible) then yes it would be totally different .

Is there any way to delete chunks in a dimension? I want to delete all the chunks in a dimension so it will generate differently, or am I better off just creating a new dimension and scraping the old one? Although there is now way of unloading dimensions so it will still exist until the server resets, which is why I would prefer to delete all the chunks so that is can reload.

Looks like I got it to work, at least in single player, not sure how it’ll do with a dedicated server. Dimensional travel is still broken, I will have to do more research on that.

Not sure if GitHub uploaded my files or not. The desktop app said it did, but the web said it did not. So I am confused, therefore here is a dropbox link, this should work. https://www.dropbox.com/sh/4w5qok10cnw8f8s/AABKW1eZ5FfdmBp_dtEf-Kj2a?dl=0

Here is the repository it tried to make on GitHub, but GitHub sucks. https://github.com/FrostDragonEmpire/MystRecraftedMod

I am trying to send a message to the server to teleport the player. But when I add this code to the GUI it crashes. BookMessageToServer bookMessageToServer = new BookMessageToServer(); CommonProxy.simpleNetworkWrapper.sendToServer(bookMessageToServer); It looks like it's crashing inside the GUI. Is the client getting mixed up in server code? I am not sure what is going on here. ---- Minecraft Crash Report ---- // You're mean.

Mostly solved, changed if(dim != playerIn.dimension) to if(dim != playerIn.dimension && !worldIn.isRemote), and it no longer crashes. It doesn't seem to be teleporting me to the right location, but when I right click a second time it does. So maybe I need a delay or something on the coord change? Not really important at the moment, I'll solve that down the road after I add the ui, because it will probably work totally different then.

I wasn't asking other people to look anything up. I am asking what other people know. I'll happily go look at other's code, it's the best way to learn.

How are other mods doing this type of teleportation?

So this is probably not the place I want to call my code, or is there a better way to transport to anther dimension?

There was, yes. I have not seen an update quite awhile, but even if there is I am doing something different.

I looked through all my crash logs and every time I crashed it was reported as dimension: 0, but the entity list was different. Overworld entities going from the overworld, and nether entities going to the overworld.

public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) { if (!playerIn.capabilities.isCreativeMode) { playerIn.dropItem(false); } playerIn.getCooldownTracker().setCooldown(this, 20); ItemStack itemstack = playerIn.getHeldItem(handIn); NBTTagCompound nbt = itemstack.getTagCompound(); int x = nbt.getInteger("x"); int y = nbt.getInteger("y"); int z = nbt.getInteger("z"); int dim = nbt.getInteger("dim"); if(dim != playerIn.dimension) { playerIn.getServer().getPlayerList().changePlayerDimension((EntityPlayerMP)playerIn, dim); ; } playerIn.setLocationAndAngles(x, y, z, playerIn.rotationYaw, playerIn.rotationPitch); return new ActionResult<ItemStack>(EnumActionResult.SUCCESS, playerIn.getHeldItem(handIn)); } @Override public void onCreated(ItemStack stack, World worldIn, EntityPlayer playerIn) { NBTTagCompound nbt = new NBTTagCompound(); nbt.setInteger("x", (int)playerIn.posX); nbt.setInteger("y", (int)playerIn.posY); nbt.setInteger("z", (int)playerIn.posZ); nbt.setInteger("dim", playerIn.dimension); stack.setTagCompound(nbt); } When I right click the item in anther dimension the game crashes, and when I reload I have teleported. So what is causing the crash? Crash log says something about null pointer. What I am I doing wrong here? Do I need to create my own teleporter and use the other method and if so how? I have been reading the code on the teleporter and it doesn't seem to do much.
