Block with composite texture

[xilef11]

Hello

 

Is there a way to create a block which has a texture composed of multiple layers and color overlays?

 

i.e for items, I have a background and a foreground texture, both white, which are rendered with a different color (see below). I would like to do the same with a block. is that possible?

in the Item class

@Override
    public IIcon getIconFromDamageForRenderPass(int meta, int pass){
    	if(hasCustomIcon)return this.itemIcon;
        if(pass == 0){
            return icon_foreground;
        }else {
            return icon_background;
        }
    }
@Override
    public boolean requiresMultipleRenderPasses()
    {
        return true;
    }
    /** sets the item's color based on the itemstack
     * 
     */
    @Override
    @SideOnly(Side.CLIENT)
    public int getColorFromItemStack(ItemStack stack, int pass)
    {
        //if there is a custom icon registered, return the same thing as Item
        if(hasCustomIcon)return 16777215;
        //otherwise, return the colors of the dust
        IDust dust = DustRegistry.getDustFromItemStack(stack);
        return pass == 0 ? dust.getPrimaryColor(stack) : dust.getSecondaryColor(stack);
       
    }
    /** sets the icon of the dust.
     * default is based on the primary and secondary colors. 
     * override for custom icon
     * 
     * @param ireg 
     */
    @SideOnly(Side.CLIENT)
    @Override
    public void registerIcons(IIconRegister ireg){
    	hasCustomIcon=false;
        //just the plain one for now
        icon_foreground = ireg.registerIcon(References.texture_path + "dust_item_fore");
        icon_background = ireg.registerIcon(References.texture_path + "dust_item_sub");
    }

thaks.

 

also, sorry for the undescriptive title, I find this problem hard to explain for some reason.

Its probably possible, but I don't know how to do it. Just try looking at the vanilla class files. Vanilla Minecraft does that with various items like potions and spawn eggs.

I think he's trying to do it for blocks

 

I would take a look at the BlockGrass file, seeing as how the actual "grassy" part of the texture is layered onto a dirt texture and then color-changed depending on its biome.

Hi

 

For sure it is possible.

 

This link might get you started (see the Block Rendering sections)

http://greyminecraftcoder.blogspot.com.au/p/list-of-topics.html

 

An ISimpleBlockRenderingHandler will let you do this easily.

thanks, although I don't see where to set the textures/colors in that. also, will i need one renderer per block?

 

the goal is to simplify adding "dusts" to my mod, making it so the dusts are created by specifying background and foreground colors, and the item and storage block are automatically created.

Hi

 

In your ISimpleBlockRenderingHandler, use the Tessellator to render your first layer, then the second layer, then the third, etc.

You can use the same ISimpleBlockRenderingHandler for multiple blocks, just register it for each one and check for the block type in your renderer.

 

You can use two passes for blocks, but they are handled differently to "passes" in items.  pass 0 is for fully opaque, pass1 is for translucent (partially opaque).  That might not be what you want...

Hello

 

Could you point me to an example please? I've never used an ISimpleBlockRenderingHandler or the Tesselator

[TheGreyGhost]

Hi

 

There's a bit about the Tessellator here

http://greyminecraftcoder.blogspot.com.au/2013/08/the-tessellator.html

 

Here's an old example from 1.6.4 which should give you the idea of how an ISBRH works

https://github.com/TheGreyGhost/ItemRendering/blob/master/src/TestItemRendering/blocks/BlockPyramidRenderer.java

and

https://github.com/TheGreyGhost/ItemRendering/blob/master/src/TestItemRendering/blocks/BlockPyramid.java

 

register it with

    RenderingRegistry.registerBlockHandler(new BlockPyramidRenderer());

 

I think it still works in 1.7.10... but I haven't tried it.  It should get you most of the way there at least.

Thanks. things look like they should work in 1.7, although I am still unsure of how to render the texture in layers (I should be able to figure it out eventually). I did hope I could create the final texture directly in the block class, but it does not look possible without using "regular" Java image modification (which can be painful/slow) unless there are methods to modify/create IIcons directly

 

EDIT: also, is block metadata passed to renderWorldBlock ? I need it to get the right colors forget that, I got it (world.getBlockMetadata).

[xilef11]

I think I figured part of it out, but the results I get are not what I'd expect, and I can't find what I'm doing wrong. probably related to vertex position and normals though.

 

ISimpleBlockRenderingHandler: (look at the last method. I also commented most faces out to try to get it right one face at a time)

Hi

 

Your code is a bit mixed up on which face points in which direction.  The Tessellator is hard to get right, when I was first getting used to it I had to hold a cardboard box and label it with a pen to get the vertices right.

 

So for example

        // east face
        //background color
        tessellator.setNormal(1F, 0F, 0.0F);
        tessellator.setColorRGBA_I(dust.getPrimaryColor(dustStack), 0xFF);
        tessellator.addVertexWithUV(x + 1.0, y + 0.0, z + 0.0, maxUBG, maxVBG);
        tessellator.addVertexWithUV(x + 1.0, y + 1.0, z + 0.0, maxUBG, minVBG);
        tessellator.addVertexWithUV(x + 0, y + 1.0, z + 0, minUBG, minVBG);
        tessellator.addVertexWithUV(x + 0, y + 0, z + 0, minUBG, maxVBG);

 

The east face is the one which is located with all xpos = x+1, so none of the points in the face are located with xpos = x+0.  The code above has all points located at zpos = z+0,  which is the north face.

In order to do the east face, you need

(x+1, y+0, z+0, maxUBG, maxVBG)

(x+1, y+1, z+0, maxUBG, minVBG)

(x+1, y+1, z+1, minUBG, minVBG)

(x+1, y+0, z+1, minUBG, maxVBG)

The normal is right.

Your code is a bit mixed up on which face points in which direction.  The Tessellator is hard to get right, when I was first getting used to it I had to hold a cardboard box and label it with a pen to get the vertices right.

 

And even then you'll fuck it up once in a while.

 

Doing this correctly took me like four hours even with a properly labeled drawing of which faces face which direction and have to be constructed in what order.

[Draco18s]

Now that was one well hidden shameless plug.

 

For a 1.6.4 micromod that I've since misplaced the code for (no really, I was syncing everything to dropbox and somewhere along the way I deleted the folders for everything pre-1.6.4).  Sure.

 

1.6.4.?  Nein, 1.5.1. and 1.6.2

 

It's one I do want to remake for 1.7 though, it's very useful.  I'd drop the slope support though, it was slightly buggy (the custom rail required air below it, so if you tried to connect a slope to a vanilla rail that was on the ground, it would work....until that rail received a block update).

[xilef11]

ok, so east = X+, up = Y+, south = Z+. therefore the (0,0,0) vertice would be the corner of the west south and down faces?

[xilef11]

yay, I managed to get a cube rendering! making a box with the coordinates of the different corners helped a lot.

 

however, I can't get it to render the multiple textures, and my UP face is completely black when using my custom texture (it was working when I used the sand texture)

Definitely something wrong here, But I dont know enough to say what. my guess is that it is related to either having two "faces" per block side or the transparency.

Hi

 

A couple of things-

1) if you are going to use brightness, you need to tessellator.setBrightness(lightValue); after every tessellator.startDrawingQuads(); because the tessellator.draw(); resets the brightness to zero.

2) for transparent blocks, the appropriate light value is the one you use, i.e.  int lightValue = block.getMixedBrightnessForBlock(world, x, y, z);

    but for opaque blocks, you need to take the light value for each face from the adjacent block, because the light value for the block itself is zero, eg

int lightValue = block.getMixedBrightnessForBlock(world, x+1, y, z); if you are drawing the east face.

3) If you are drawing the FG on top of the BG you should 'nudge' the FG face out by a very small amount to make sure it renders over the top of the BG face.  Otherwise it can get partially hidden or lead to weird stripy effects.  For example, for the east face, draw BG at x+1, and the FG at x+1.001;

 

Apart from that, your code looks ok to me.  Are you sure your dust.getSecondaryColor(dustStack) etc are correct?  the setNormals should only be required for inventory displaying; I don't think it should hurt to have them for block rendering too but you could try commenting them out if you are still having trouble.

After a bit more testing, it seems the problem is my textures, since it works fine when using vanilla textures. How should transparency be handled? I currently have two png files with transparent pixels.

[TheGreyGhost]

Hi

 

Minecraft uses two kinds of transparency -

the first is "on/off" transparency - any texels with an alpha less than 0.1 are fully transparent, any texels with an alpha of 0.1 or more are drawn fully opaque.  this is the "pass 0 " rendering.  Are you sure your png files have the proper alpha channel?

the second is alpha-blending transparency, where the texels are drawn according to their alpha level eg 0.6 means 60% opaque, 40% transparent.  this is "pass 1".

 

I think you want the on/off kind.  If you use alpha values of 0.0 or 1.0 (0 or 255) it should work fine.  If you are colouring the overlays afterwards, the png should have white texels - i.e. if your texels are green, and you try to colour them blue when rendering, you will get black.

the second is alpha-blending transparency, where the texels are drawn according to their alpha level eg 0.6 means 60% opaque, 40% transparent.  this is "pass 1".

 

Note:

In pass 1, alpha below 0.1 is also drawn as fully transparent.  It's really annoying.

[xilef11]

the texels are either fully opaque or fully transparent, so the problem must be somewhere else... It seems that the textures are not correctly loaded, since a println of them in the renderer returns the following:

TextureAtlasSprite{name='runesofwizardry:dustStorage_bg', frameCount=0, rotated=false, x=0, y=0, height=0, width=0, u0=0.0, u1=0.0, v0=0.0, v1=0.0}

 

however, the log shows no message about a missing texture. Here is my block class:

    //Icons for the background and foreground
    private static IIcon bgIcon,fgIcon;
    public IDustStorageBlock(Material mat){
        super(mat);
    }
    /** returns the dust that forms this block **/
    public abstract IDust getIDust();
    @Override
    public int damageDropped(int i) {
        return i;
    }
    public IIcon getBackgroundIcon(){
        return bgIcon;
    }
    public IIcon getForegroundIcon(){
        return fgIcon;
    }
    //TODO finish setting up the block
    //TODO Icons and stuff

    @Override
    public void registerBlockIcons(IIconRegister reg) {
        //sand icon, used only for the particles when breaking block
        blockIcon = Blocks.sand.getIcon(0, 0);
        if(bgIcon==null||fgIcon==null){
            bgIcon = reg.registerIcon(References.texture_path+"dustStorage_bg");
            fgIcon = reg.registerIcon(References.texture_path+"dustStorage_fg");
        }
    }

    @Override
    public boolean renderAsNormalBlock() {
        return false;
    }

    @Override
    public int getRenderType() {
        return DustStorageRenderer.getRenderID();
    }
}

Update: it seems that removing the if(**Icon==null) statments before registering the textures fixed the problem. However, when the blocks fall, they get the sand texture. is there a (hopefully simple-ish) way to fix that?

[xilef11]

(bump...) I would guess I have to override something in EntityFallingBlock, but I can't find what
