Use BufferedImage as texture in 1.14.4


PTLC

Recommended Posts

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 ? :)

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...)

It was because I wanted to create like red_blockblue_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.

    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
