Hey Guys!

I created a sign, which can be used to write colored text. If you press a button in the GUI, a EnumChatFormatting object is added to the signs string.

 

The problem is, that the text is rendered wrong.

Here is one Text in the GUI (where everything is fine)

And here is the same text ingame:

 

The Renderer method:

 

 

(Placed in a method extended from the Renderer superclass, shown below)

@Override
public void renderTileEntity(TileEntity te, World world, int x, int y, int z, int meta, Block block, boolean isItemRendered) {
	if (isItemRendered) {
		GL11.glScalef(1.2F, 1.2F, 1.2F);
		GL11.glTranslatef(0.0F, -0.1F, 0.4F);
	}

	this.startDrawingQuads();
	this.rotate4Steps(meta);
	this.bindMCTexture(((ModBlockLargeSign)block).getBacksideName());
	this.setNormal(0.0F, 0.0F, -1.0F);
	this.renderFace(0.0D, 0.0D, 0.0D, 1.0D, 0.0D, 0.0D, 1.0D, 1.0D, 0.0D, 0.0D, 1.0D, 0.0D);
	this.setNormal(0.0F, 1.0F, 0.0F);
	this.renderFaceTexCut(1.0D, 0.125D, 0.0D, 1.0D, 0.0D, 1.0D, 1.0D, 0.0D, 1.0D, 1.0D, 0.125D, 0.0D, 1.0D, 0.125D);

	this.renderFaceTexCut(1.0D, 0.125D, 0.0D, 0.0D, 0.125D, 1.0D, 0.0D, 0.125D, 1.0D, 0.0D, 0.0D, 0.0D, 0.0D, 0.0D);
	this.setNormal(1.0F, 0.0F, 0.0F);
	this.renderFaceTexCut(0.125D, 1.0D, 0.0D, 0.0D, 0.125D, 0.0D, 0.0D, 0.0D, 0.0D, 1.0D, 0.0D, 0.0D, 1.0D, 0.125D);
	this.setNormal(-1.0F, 0.0F, 0.0F);
	this.renderFaceTexCut(0.125D, 1.0D, 1.0D, 0.0D, 0.0D, 1.0D, 0.0D, 0.125D, 1.0D, 1.0D, 0.125D, 1.0D, 1.0D, 0.0D);
	this.finishDrawing();
	this.startDrawingQuads();
	this.setNormal(0.0F, 0.0F, 1.0F);
	this.bindModTexture(((ModBlockLargeSign)block).getFrontsideName());
	this.renderFace(1.0D, 0.0D, 0.125D, 0.0D, 0.0D, 0.125D, 0.0D, 1.0D, 0.125D, 1.0D, 1.0D, 0.125D);
	this.finishDrawing();

	if (!isItemRendered) {
		FontRenderer f = this.func_147498_b();
		TileEntityLargeSign tile = (TileEntityLargeSign)te;

		float scale = 0.01F;
		GL11.glTranslatef(0.5F, 0.5F, 0.5F);
		GL11.glScalef(scale, -scale, scale);
		GL11.glTranslatef(0.0F, 0.0F, -0.374F / scale);

		for (int i = 0; i < 6; i ++) {
			String s = tile.getCurrentText()[i];
			if (s != "")
				f.drawString(s, -f.getStringWidth(s) / 2, i*16 - 45, 0); //Color is set to 0 to render in black by default!
		}
	}
}

Call in the GUI:

 

GL11.glPushMatrix();
        
        GL11.glTranslatef(this.width / 2, 80.0F, 0.0F);
        float f1 = 120.0F;

        GL11.glTranslatef(0.0F, -0.5F, -0.5F);
        GL11.glRotatef(180, 0, 1, 0);
        GL11.glTranslatef(0.0F, 0.5F, 0.0F);
        
        TileEntityRendererDispatcher.instance.renderTileEntityAt(this.te, -0.5D, -0.75D, -0.5D, 0.0F);

        GL11.glScalef(f1, f1, f1);
        GL11.glPopMatrix();

 

 

Why is the sign rendered different ingame than in the GUI?!

Hi

 

I suspect it's because you're setting the render colour to white in the game (your sign is in full sunlight, yes?) but the fake block coordinates you use in the GUI is not full sunlight, so you get a grey.

 

this.t.setColorOpaque_F(bright, bright, bright);

 

This link might help with some background info

-TGG

The problem is, that the error appears not in the gui, but in the world.

I want this sign to be grey, but in the world it's white.

Everything from §8 up to §f is rendered white in the world, but it shouldn't!

 

A problem might be this method:

brightness = block.getMixedBrightnessForBlock(world, teX, teY, teZ);

because with this code line brightness is set to 1.572864E7 as my debugging test showed.

But I also tried setting it to different values manually, nothing worked.

 

It could be this problem, but I don't know, how I could solve it:

The brightness of the texture is always set to 1.0F.

So, if you get orange (R:1.0F; G:0.5F; B:0.0F) it is turned to yellow (R:1.0F; G:1.0F; B:0.0F).

Also, al the Colors up from §8 have little parts of all color and this is set to 1.0F each.

 

This could be the problem, but I don't know why it appears

 

Anyone?

I looked into TileEntitySignRenderer till i finally found out that I forgot to set the normal.

 

But I really can't understand, why this has such big effect
