Inventory progress bar not working

[AskHow1248]

Hi everybody, I am making a gui with a progress bar (arrow actualy), but for some reason it doesn't update properly.  I'm not sending any packets, which might be part of the problem, but I don't know how to fix it.

public GUIMageForge(InventoryPlayer invPlayer, TileEntityMageForge tileEntity) {
	super(new ContainerMageForge(invPlayer, tileEntity));

	xSize = myXSize;
	ySize = myYSize;

private static final ResourceLocation texture = new ResourceLocation("tn3", "textures/gui/mageforgeGUI.png");

@Override

	GL11.glColor4f(1, 1, 1, 1);

	super.mc.renderEngine.bindTexture(texture);

	drawTexturedModalRect(this.guiLeft, this.guiTop, 0, 0, xSize, ySize);

	drawArrow();

}

private void drawArrow() {

	int srcX = 0;
	int srcY = 202;

	int endX = (int) ((double)116 * getTile().getPrecentFinished());
        
	drawTexturedModalRect(guiLeft + 32, guiTop + 52, srcX, srcY, endX, 22);

}

protected void drawGuiContainerForegroundLayer(int x, int y) {

	if(getTile().getTimeLeft() != -1)
		fontRenderer.drawString("Time Left: " + getTile().getTimeLeft(), 50, 50, 0x404040);

	fontRenderer.drawString("Heat: " + getTile().getHeat(), 135, 100, 0x404040);

}

By "doesn't update properly" I mean that when I am crafting something (the arrow is supposed to progress as I nears completion), nothing happens.

[AskHow1248]

Do I need to addCraftingToCrafters when I open the gui for a player?  I did everything from the furnace container, but it sill won't work.

Also, if I put print statements in the method, they print the correct value, but if I put the same statements in the gui, but using the return value of the method, they print 0 (wrong), even though the method prints (and returns) the correct value.

Sorry, stupid mistake.  It still doesn't work though (I cast both to double).

par2 / 100D is sufficient.

 

(int / double = double)

Ok.  I will work on it.  I can give you my complete source code if you tell me how.

[AskHow1248]

I figured it out.  In the updateEntity() for my tile entity, I had a if(!worldObj.isRemote) statement, which meant it didn't get updated on the client side.  Thank you everybody how helped.
