[SOLVED][1.8]Attempting to create dynamic item textures, failing.

[Sgmjscorp]

Hello there!  I'm trying to make an item that changes its texture dynamically but have so far made no progress into figuring out how, even after going through a few tutorial codes that are supposed to do "animation". No luck, so I want to see if anyone out there can see what I'm missing and help me fix it.  Posted is the relevant coding, and if you need anything more please let me know.

I would like to have multi-layer rendering as the second layer is going to have a dynamic color based on... well, you can see that in the item code. 

If anyone could lend a hand or point out where my stupid struck, please let me know!  (Preferably in detail . I'm bright, but a little dense.)

Hi

 

What are the symptoms of the problem?  Any relevant console errors, screenshots, or youtube videos we could look at?

 

Cheers

Basically a black and purple box being held while the item slot still holds its original texture.

 

Edit:

 

 

 

 

 

That could've taken less time...

[Sgmjscorp]

Bump--

 

I've updated to the latest forge version (11.14.1.1336) and it still has the same issues.  Any help would be greatly appreciated!

[TheGreyGhost]

So the held texture animates incorrectly?  Does it cycle through the frames?  In one of the screenshots I see it looks fine.

 

Does your error console get any 'missing texture' or 'missing model' messages?

It's not an animation, it's supposed to change its texture based on how filled it is, thus why I showed the tooltips in the screenshots as well.  I based my code off of animation because that was the closest example I could find to a dynamic texture.

 

I receive no missing texture or missing model messages, and even put in a bit of code to verify that.  They load fine!  Just not when rendering .-.

[TheGreyGhost]

Well one of your models renders fine, the rest don't, which suggests to me that you haven't registered the other names properly, perhaps your paste-names-together-from-bits code has a subtle bug in it.  The only way I know to debug this is to trace into the vanilla code and figure out which bit isn't working as you expect.

 

For example, trace into

ModelBakery.addVariantName(BioFrame.itemExtractor, BioFrame.modID+":extractor",

 

or trace out of

public ModelResourceLocation getModel(ItemStack stack, EntityPlayer player, int useRemaining)

and see why your ModelResourceLocation is not found in the registry

etc

 

Unfortunately it's pretty complicated in there so it might take a while unless you're lucky.  I can't tell what's wrong just from looking at your code, except that it's almost certainly a registration problem and not a json file problem because you're not getting any error messages.

Thank you, GreyGhost!  It was registration, as such I forgot to actually register the alternate textures...

 

registerBakery(), when I did a call hierarchy, had nothing calling it.  Thank you, as I doubt I'd have noticed that without your pointing out it was a registration error.  Now to try to make the actual item texture change...  That's gonna be fun >

 

Thank you again!
