[1.6.4] Rendering container stuff into a model

Posted March 15, 201411 yr

Hey guys,

I want to render some things from a tile entities container physically into the model. However, I'm having a bit of trouble with it.

I believe all I need to do is "sync" the container from the server to the client; but I'm not exactly sure how. My code is failing when doing a null check for the itemstack though, so I think that's a good guess.

Here is my renderer, tile entity, and container. Anyone able to point me in the right direction?

I'm not entirely sure, but you may be able to do all the calculation on the server and use a packet handler to send the data to the client and have the client render the model.

Don't be afraid to ask question when modding, there are no stupid question! Unless you don't know java then all your questions are stupid!

You can do this by creating a method in your tile entity to check for the item in the slot like so

public boolean hasBook(int slot)
{
// on phone so can't remember method but there is a method in IInventory to check for items in slot
if(items.unknownMethod[slot] instanceof ItemBook)
      return items.unknownMethod[slot];

Then do a check in your renderer and if so render that part of the model.

That would only work for something like Bibliocraft's bookshelf, where the physical item in the slot has no relevance to what is rendered. I need to know what itemstack is in the slot, because I'll be rendering that exact stack

Then do a check in your renderer and if so render that part of the model.

You'll need to send packets. Easiest way is via the description packet of the TileEntity.

Awesome; any examples of this anywhere?

How Do I Commission A Mod

Hey, that sounds like a really fun project. I can definitely help with creating custom models, animations, and setting up the core mechanics like leveling and stats. For sound effects and BGM, I can also handle imports or guide you on how to set them up properly in forge 1.20.1.
Could you tell me a bit more about the theme or style you’re going for (like which anime or type of gameplay)? Also, what’s your budget and timeline looking like?
