[1.8.9] Generating Block Texture On Runtime

[AManNeedaAName]

I want to create a block that its texture is generated randomly, without using any .png file or .json file and just by a BufferedImage, any help?

[Elix_x]

The textures are randomly generated (choose one):

- On MC load.

- On world load.

- A few times while world running.

- 9000+ times / tick (╯°□°）╯︵ ┻━┻

 

This choice will completely change the way it should be implemented.

Use a TextureAtlasSprite and override it's

load

method and make sure that it gets added to the sprite sheet (subscribe to TextureStitchEvent).

 

Do note that by overriding

load

you'll end up skipping LOTS of vanilla debug behavior regarding missing/corrupt textures and the game will either crash (in vanilla code), or not behave properly, and you'll be on your own to debug.

 

Here's a TextureAtlasSprite class I wrote once that combines two different .png files during startup.

@Draco18s woooow... Stop it... Why so much pain? Srsly?

 

Step 1: create a texture location, for example "cookiemod:zenyancookie" and use it in your block json.

Step 2: Create custom

IResourcePack

implementation, throw it into default resource packs in minecraft using reflection.

Step 3: once somebody asks for texture resource and it's your texture (check domain and location, location will be textures/senyancookie in this case), return resource that ImageIOs your png into output stream, which you clone into inout stream using apache stream utils and return.

Step 3.5: If you want your image to persist between RP reloads, just output it into

ByteArrayOutputStream

, store

byte[]

and return

ByteArrayInputStream

from that array as resource.

Gosh, probably because that's what people told me to do on this forum back when I was trying to figure out how to combine textures....

Is not so easy to make random block texture as before. From what I read you can simply generate one and apply it directly to a Block by using the methods before 1.8 which are still buried in the code but you need to create a fake json model with everything empty and you cannot add it to a creative tab. Is a hack but is not guaranteed is gonna work forever.

 

in the json model you would have something like

{

    "": {

        "": { "": "" }

    }

}

 

or some other bs system. I forget now. But there is a hacky way to do it. It only works for blocks.

@trollworkout Did you read my previous post? It's totally possible and not hard at all.

 

@Draco18s This is applicable in 1.8, hell that resource pack method works in 1.7.10 (but not needed).

Since 1.9, we've got another way of doing this, with

IBaked

, in case we have to combine tons of layers (to not hurt performance).

Just FMI (for my information), how are/were you actually using that dynamic atlas sprite?
