Here are two images to see the problem:

As you can see my leaves always render transparent.

 

Here's my code:

Thanks for helping

I think part of the problem may be the light opacity you set in the block constructor. The javadoc says that it determines how much light passes through the block. Set it to 0, and then tell me what happens.

Hi

 

Vanilla changes the icon depending on the graphics level.  One has transparency, the other doesn't.  Also shouldSideBeRendered and isOpaque cube, to stop the "inside" of the foliage being rendered unnecessarily

 

Take a look at this code from 1.6.4

BlockLeavesBase::
    /**
     * Returns true if the given side of this block type should be rendered, if the adjacent block is at the given
     * coordinates.  Args: blockAccess, x, y, z, side
     */
    public boolean shouldSideBeRendered(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)
    {
        int i1 = par1IBlockAccess.getBlockId(par2, par3, par4);
        return !this.graphicsLevel && i1 == this.blockID ? false : super.shouldSideBeRendered(par1IBlockAccess, par2, par3, par4, par5);
    }
BlockLeaves::
    
    private int iconType;  /** 1 for fast graphic. 0 for fancy graphics. used in iconArray. */
    private Icon[][] iconArray = new Icon[2][];

    public static final String[][] field_94396_b = new String[][] {{"leaves_oak", "leaves_spruce", "leaves_birch", "leaves_jungle"}, {"leaves_oak_opaque", "leaves_spruce_opaque", "leaves_birch_opaque", "leaves_jungle_opaque"}};

    /**
     * Is this block (a) opaque and (b) a full 1m cube?  This determines whether or not to render the shared face of two
     * adjacent blocks and also whether the player can attach torches, redstone wire, etc to this block.
     */
    public boolean isOpaqueCube()
    {
        return !this.graphicsLevel;
    }

    /**
     * From the specified side and block metadata retrieves the blocks texture. Args: side, metadata
     */
    public Icon getIcon(int par1, int par2)
    {
        return (par2 & 3) == 1 ? this.iconArray[this.iconType][1] : ((par2 & 3) == 3 ? this.iconArray[this.iconType][3] : ((par2 & 3) == 2 ? this.iconArray[this.iconType][2] : this.iconArray[this.iconType][0]));
    }

Minecraft still has that call for the "fancy" setting, in BlockLeaves (setGraphicsLevel), which only applies to vanilla leaves, sadly.

Basically, before returning the IIcon for your block, do

setGraphicsLevel(Minecraft.getMinecraft().gameSettings.fancyGraphics)

, then return the corresponding IIcon.

 

And for my sake, please deobfuscate your code.

Wait, so the setLightOpacity has no correlation either? Must've misread the javadoc.

Thanks to all of you, it's solved
