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. ?

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

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 ?

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

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

can it be possible ?

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...)

 

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.

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

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.
