Use BufferedImage as texture in 1.14.4

[PTLC 0]

Hello,

I want to create a mod where textures are generated at the start of Minecraft from bufferedImage create in code. 😄

For example, if I want to create a stone with custom color, it will take the stone resource, color it and link it to a ResourceLocation. 

But I don't know how to do this step.

 

I try to use DynamicTexture 😅 :

public static ResourceLocation addTexture(BufferedImage img, ResourceLocation loc) {
	TextureManager textureManager = Minecraft.getInstance().getTextureManager();
	NativeImage n = new NativeImage(img.getWidth(), img.getHeight(), true);
	for (int i = 0; i < img.getWidth; i++) {
		for (int j = 0; j < img.getHeight(); j++) {
        	double[] c = img.getRaster().getPixel(i, j, new double[0]);
            color = (((((c[3] >> 8) + c[2]) >> 8) + c[1]) >> 8) + c[0];
			n.setPixelRGBA(i, j, color);
		}
	}
	DynamicTexture dyn = new DynamicTexture(n);
	
	textureManager.loadTexture(loc, dyn);
	return loc;
}

 

But I have errors like that 😖 :

FATAL ERROR in native method: Thread[Server-Worker-3,5,main]: No context is current or a function that is not available in the current context was called. The JVM will abort execution.

And I don't know why...

 

I've made many searches and find nothing working

I hope you can help me. 🍀

That's not the complete stack trace.

You are most likely not doing this during the correct event. Where are you calling this method?

I've try to call this method from the events FMLClientSetupEvent and then from TextureStitchEvent.Pre.

[diesieben07 6781]

Both of those events are not called on the main thread and are not the correct place to do this.

TextureStitchEvent.Post is probably the most appropriate.

It doesn't crash 😮

But it doesn't have effect in game...

I think the texture can be load from BufferedImage now, but I don't think how to display it as block texture

With a model (in a file) probably, I try but it doesn't work

But it's not the final goal because I want blocks with name and id defined in code

Do you have a solution ?

Do not create blocks dynamically. You should always register the exact same blocks, items, etc. not depending on any kind of configuraton or other dynamic things.

It isn't possible ? ? ?

I wanted to create config (or with a seed) at the first mod start, and create the same blocks following the config

Make one block then which masks as multiple. It is highly problematic to dynamically register blocks. 1.14.4 forbids it completely.

[PTLC 0]

And if the mod create a block with a specific same id but with different texture (following config),

can it be possible ?

[diesieben07 6781]

Please clarify what you mean.

[PTLC 0]

For exemple, I want to create a block with the id colored_stone

 - if in my config file there is red, the block will be red

 - if there is #FF8080, the block will be colored with this color

 Furthermore I want the possibility to add a pattern amont several patterns (like ore, plant, flower...)

You'll need a tile entity to store how the block should look.

A tileentity ? Even if all the colored_block are the same ?

I want : If you stop Minecraft, edit the config and restart a world, all the existing colored_block will change texture.

Well, then I don't see why you wanted multiple blocks in the first place...

[PTLC 0]

No I don't want multiple colored_block,

Just a colored_block which will never change from the start to the stop of Minecraft. And it's texture is drew at the start

Then what do you mean by this?

[PTLC 0]

It was because I wanted to create like red_block, blue_block and green_block but only one of them per Minecraft launch.

But I can create a colored_block and link it to a texture during the Minecraft start.

It will be same in game.

I juste don't how to link my texture (BufferedImage) to my colored_block at Minecraft start.
