Creating a "hang to wall" item

[Malharhak]

Hi,

 

I've just finished some of the first forge tutorials to get started. Now the first mod I want to make is a simple thing : I have a few objects that I would like the player to be able to hang to walls (like paintings, but standard block size and no random texture).

 

So I looked a little bit at Minecraft's code and saw the EntityPainting and EntityHanging, but I have no idea how they actually work, the code is pretty obscure.

More specifically I didn't find anywhere in these classes where the texture is set. Also, I assume they are not created the same way a standard block so I'm not sure what I exactly need to do to make it work.

 

Edit : I also couldn't find where the actual painting Item is in the code. I initially wanted to look at how it's done but the only thing I found is the EntityPaiting, which I assume is the result of the painting item being placed.

 

Could anyone point me in the right direction to get started doing that ?

 

Thanks !

Hi

 

There are a few links on this site that might help you with the background information.

http://greyminecraftcoder.blogspot.com.au/p/list-of-topics.html

especially - Important classes continued, and the section on Blocks and Items.

 

You have a few choices on how you can have a picture that you hang on the wall - you could make a transparent block with just one wall showing the object, you could have it in a picture frame like you can frame items, or you could use an entity like EntityPainting.

 

EntityPainting is rendered in RenderPainting.  The trick is that func_77010_a is turning each pixel of the texture into a little cube.  The texture comes from field_110807_a which is a single file containing all the pictures.  I think that's probably not what you want.

 

ItemHangingEntity is the item used by a painting.

 

What would I recommend?

Copy ItemHangingEntity to your own class, similarly for EntityPainting.  Adapt the methods to your new classes and the textures you want.  Create an EntityRenderer class for your EntityPainting and add custom render methods.  Register all your new classes.

It's fairly complicated, this tutorial might help

and part2 as well.

Hi,

 

I ended up finding these renderers and I started to do just that, but kind of randomly with no background info, so it didn't work, but with your links I will probably be able to understand what I'm doing. Thanks !

If you want to make a block that clings to the side of something, you'll need to change its block bounds. If you override the setBlockBoundsBasedOnState method in Block, you can set block bounds for distinct blocks in the world by using setBlockBounds(minx, minY, minZ, maxX, maxY, maxZ)

 

Changing the block bounds will make your block less like a cube, depending on what you set them to.
