[1.7.10] RGB Based Block Textures

[Crow]

I am adding alot of blocks to my mod. 1000+. All just solid colors.

I am wondering, is there a way to have the texture generate for each

block using RGB without each block needing a texture?

 

Idea is something like this...

 

whiteBlock = new ModBlocks("White"), Material.iron, 1.5F, 10F, Block.soundTypeMetal, 255, 255, 255);

 

public class MODBlocks extends Block 
{
protected MODBlocks(String name, Material mat, float hard, float resi, SoundType sound, int R, int G, int B) 
{
	super(mat);
	this.setBlockName(name);
	this.setHardness(hard);
	this.setResistance(resi);
	this.setStepSound(sound);
	this.setCreativeTab(MOD.tabMODTabs);
        
        GameRegistry.registerBlock(this, this.getUnlocalizedName().substring(5));
}

/*	?????
@SideOnly(Side.CLIENT)
protected IIcon blockIcon;

@SideOnly(Side.CLIENT)
@Override
public void registerBlockIcons(IIconRegister p_149651_1_)
{
blockIcon = p_149651_1_.registerIcon(MOD.modid + ":" + this.getUnlocalizedName().substring(5));
}

@SideOnly(Side.CLIENT)
@Override
public IIcon getIcon(int p_149691_1_, int p_149691_2_)
{
return blockIcon;
}
?????*/
}

Maybe look at how grass color is changed per biome?

[Crow]

I wouldn't know how to translate it from being texture & biome dependent to

being dependent on only RGB.

[Eternaldoom]

You could just have a white texture and color it with RGB

[Crow]

That's what I was thinking but I don't know how...

[Eternaldoom]

Heres an example for RGB. Try putting this in a block:

int red = 0, green = 0, blue = 255;

@Override
@SideOnly(Side.CLIENT)
    public int getRenderColor(int par)
    {
        String hex = String.format("#%02x%02x%02x", red, green, blue);        
        return Integer.parseInt(hex.replaceFirst("#", ""), 16);
    }

@Override
@SideOnly(Side.CLIENT)
    public int colorMultiplier(IBlockAccess p_149720_1_, int p_149720_2_, int p_149720_3_, int p_149720_4_)
    {
	String hex = String.format("#%02x%02x%02x", red, green, blue);        
        return Integer.parseInt(hex.replaceFirst("#", ""), 16);
    }

[Eternaldoom]

And make sure you are importing java.awt.Color

[Crow]

Error..

 

java.util.IllegalFormatConversionException: x != java.lang.String

 

on

 

String hex = String.format("#%02x%02x%02x", red, green, blue); 

 

Just to make sure you know I am calling the RGB values from the constructor as in the op.

I changed the int to String and added private Strings for red, green and blue.

 

Blue = new MODBlocks("Blue", Material.iron, 1.5F, 10F, Block.soundTypeMetal, "0", "0", "255");

 

public class MODBlocks extends Block 
{
private String red;
private String green;
private String blue;

public MODBlocks(String name, Material mat, float hard, float resi, SoundType sound, String R, String G, String B) 
{
	super(mat);
	this.setBlockName(name);
	this.setHardness(hard);
	this.setResistance(resi);
	this.setStepSound(sound);
	this.setCreativeTab(NEC.tabNECTabs);
	red = R;
	green = G;
	blue = B;

I was editing my post when you replied.

 

and you'll have to forgive me, I don't know what to do with that exactly..

[Eternaldoom]

I posted that code instead of just using hex colors because he said he wanted to use RGB. You're right, just using hex is better

[Crow]

Seems that is what I would use if I were to have a class for each block.

But am predicting little over 1000 blocks. So I would prefer to just have all of them

pass through one block class.

 

What if I already have the hex for all the colors I need? couldn't I take that from the constructor as a string?

I would prefer to use RGB personally but if its easier to use hex without conversion I can, just don't know how.

lol.. I am still a noob at all this but learning fast. Thanks for helping.

[Crow]

ID's shouldn't be a problem anymore once we get a 1.8 update right?

and i know absolutely nothing about TileEntitys... Might be time to learn.

[Crow]

Is there an easy way to assign meta using the format I have?

Maybe just making 16 blocks the same unlocalizedname and setting a meta?

or is it a bit more complicated than that?

[Crow]

Got it. Thanks for the help. Looks like I got a little more to learn before attempting this. Thanks

[Crow]

Ok so I have done my research and checked out a few tutorials and came up with this..

 

public class colorBlocks01 extends Block
{
@SideOnly(Side.CLIENT)
private IIcon[] texture;

final static String[] subBlocks = new String[] {"white","orange","magenta","yellow",
												"lightblue","lime","pink","gray",
												"lightgray","cyan","purple","brown",
												"blue","green","red","black"};

public colorBlocks01() 
{
	super(Material.rock);
	this.setHardness(3.5F);
	this.setResistance(5.0F);
	this.setCreativeTab(NEC.NECTab);
}

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister)
{
	texture = new IIcon[subBlocks.length];
	for(int i = 0; i < subBlocks.length; i++)
	{
		texture[i] = iconRegister.registerIcon(NEC.modid + ":" + "colors-" + subBlocks[i]);
	}
}

@SideOnly(Side.CLIENT)
public void getSubBlocks(Item block, CreativeTabs tab, List list)
{
	for (int i = 0; i < subBlocks.length; i++)
	{
		list.add(new ItemStack(block, 1, i));
	}
}

@SideOnly(Side.CLIENT)
public IIcon getIcon(int side, int meta)
{
	return texture[meta];
}

public int damageDropped(int meta)
{
	return meta;
}

}

 

public class ItemColorBlocks01 extends ItemBlock
{

final static String[] subBlocks = new String[] {"white","orange","magenta","yellow",
												"lightblue","lime","pink","gray",
												"lightgray","cyan","purple","brown",
												"blue","green","red","black"};

public ItemColorBlocks01(Block block) {
	super(block);
	this.setHasSubtypes(true);
}

public String getUnlocalizedName(ItemStack itemstack)
{
	int i = itemstack.getItemDamage();
	if(i < 0 || i >= subBlocks.length)
	{
		i = 0;
	}

	return super.getUnlocalizedName() + "." + subBlocks[i];
}

public int getMetaData(int meta)
{
	return meta;
}
}

 

QUESTION- Now that I have that and it works, how could I go about swapping the texture for an RGB value (preferable), or hex?

Hi

You can probably achieve this by overriding Block.colorMultiplier().

Change the return value to the colour you want; assuming you are encoding your 1024 colours using a mixture of block and metadata, you will probably need

IBlockAccess.getBlockMetadata(wx, wy, wz) too

I kinda figured colorMultiplier might come into play but I have no idea how to modify it to make it do what I want it to do.

It would have to process 16 different blocks with individual colors.

Hi

 

You might find this link useful

http://greyminecraftcoder.blogspot.com.au/2013/08/lighting.html

 

Make your texture grey scale (or fully white if you want uniform colour)

 

colorMultiplier returns a colour in RGB format.

 

If you return 0xFFFFFF it will be white (no colour change)

return 0x0000FF it will be shaded blue

etc

 

Try it and see....
