[Solved] A block with different faces? e.g. Furnace

[ProgrammerCam]

I wanted to make a block similar that looks similar to a furnace. I need it to change the front face based on where you are looking, like a furnace.

If someone could post up code it would be [glow=yellow,2,300]awesome[/glow]! 

[sequituri]

BlockFurnace? I think I'd start there for a good example of the code.

Ok cool thanks I've copied the code, it all works smoothly, except for one thing, the furnace faces always a set direction; it never changes. I checked the furnace code and well i have been unsuccessful...

If i could get some help that would be awesome!

For some reason the code thing isn't working....

So, what you want the face to change sides dynamically when you walk around it?

[ProgrammerCam]

like you know when you place a furnace it faces you? I want that... This doesn't do that

[sequituri]

You want to copy onBlockPlacedBy(World p_149689_1_, int p_149689_2_, int p_149689_3_, int p_149689_4_, EntityLivingBase p_149689_5_, ItemStack p_149689_6_)

 

That is where the direction is determined and set.

 

[ProgrammerCam]

Thank you so much but one more problem.... the block. When you hold a furnace on the right hand side of the icon is the front and on the left side is the side icon. How can i make the icon of my item like that. both the left and right side is the icon for the side.

[ProgrammerCam]

Heres an image of what i mean if it works or not is another thing....

but hey! Thanks for your help!

The Furnace uses metadata to determine it's placed direction (even when rendering on the hotbar.) The facing when in inventory is due to a trick in RenderBlocks where renderBlockAsItem(Block, meta, color) changes the metadata of the furnace used to lookup icon to 2. So, it forces the furnace to face the proper way to render the item in the hotbar.

You might have to set your own block renderer to overcome that limitation.

A possible workaround I haven't tried is to always create your ItemStack with a furnace with metadata = 2. When it is actually placed it will change accordingly, of course.

You could also do something way more easy. If the furnace is in the inventory, the metadata is 0, but if it's placed down, the metadata is 2,3,4 or 5. So in your getIcon method, check for a metadata that's 0, and if the side is 2, you need to set the front texture.

[sequituri]

Yes indeed. I hadn't even considered how the furnace will only ever face one of 4 directions, rather than 6. Good advice!

Guys i don't understand a word...

Ima noob. 

Could you give me code and tell me where to put it?

thanx.

I would create a new ItemBlock, that's how wool renders differently in your inventory (and hand) based on metadata. http://www.minecraftforge.net/wiki/Metadata_Based_Subblocks#MultiItemBlock

 

If you are experienced in java you should be able to use this tutorial to get the results you want.

Thank you so much...

It helps!

Works now ty!
