Like the title says, I'm stuck at using the overlay method drawTexturedModalRect for a custom GUI. More specific, I have 4 custom texture places to be updated, 2 of them are working , the others not. I will only post the GUI***.java , because the other code isn't the Problem.

 

 

package net.minecraft.src;

import org.lwjgl.opengl.GL11;

public class GuiMixer extends GuiContainer
{
private TileEntityMixer mixerInventory;

    public GuiMixer(InventoryPlayer par1InventoryPlayer, TileEntityMixer par2TileEntityMixer)
    {
        super(new ContainerMixer(par1InventoryPlayer, par2TileEntityMixer));
        mixerInventory = par2TileEntityMixer;
    }

    /**
     * Draw the foreground layer for the GuiContainer (everythin in front of the items)
     */
    protected void drawGuiContainerForegroundLayer()
    {
        fontRenderer.drawString(StatCollector.translateToLocal("container.inventory"), 8, (ySize - 96) + 2, 0xffffff);
    }

    /**
     * Draw the background layer for the GuiContainer (everything behind the items)
     */
    protected void drawGuiContainerBackgroundLayer(float par1, int par2, int par3)
    {
        int i = mc.renderEngine.getTexture("/Items/GUI/mixer.png");
        GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        mc.renderEngine.bindTexture(i);
        int j = (width - xSize) / 2;
        int k = (height - ySize) / 2;
        drawTexturedModalRect(j, k, 0, 0, xSize, ySize);

        if (mixerInventory.isBurning())
        {
            int burn = mixerInventory.getBurnTimeRemainingScaled(14);
            drawTexturedModalRect(j + 25, (k + 36 + 14) - burn, 176, 14 - burn, 14, burn);
        }

        int update = mixerInventory.getCookProgressScaled(10);
        //left up  (working)
        drawTexturedModalRect(j + 84, k + 24, 177, 30, update, update);
        
        //right up  
        drawTexturedModalRect(j + 122 , k+ 24 , 186, 50, -update, update);
        
        //left down
        drawTexturedModalRect(j + 84, k + 62, 177, 49, update , -update);
        
        //right down  (working)
        drawTexturedModalRect(j + 122, k+ 62, 186, 29, -update, -update);
        
    }
}

 

 

I think the different algebraic signs are the reason, but I'm searching through the Minecraft source for hours and I only found out, that compared to the two working ones, it should work.

 

Try -1*(blank) instead of -(blank)

 

Didn't work.

It's really frustrating , because 2 are working and the other two don't change at all.

 

#Fixed

 

I had to write a new drawTexturedModalRectMethod.

For those of you who are also having trouble, at creating vertical overlays with negative parameters, I will post the code.

 

EXPLANATION:

It's needed, because when you call the method with one negative and one positive size(drawTexturedModalRect(int x, int y, int u, int v, int width, int height), the order of the Corners being added is changed.

 

 

CODE :

 

package net.minecraft.src;

public class GuiContainerNew extends GuiContainer
{

public GuiContainerNew(Container par1Container) 
{
	super(par1Container);
}

@Override
protected void drawGuiContainerBackgroundLayer(float var1, int var2,int var3) 
{

}

    public void drawTexturedModalRectRevert(int par1, int par2, int par3, int par4, int par5, int par6)
    {
        float var7 = 0.00390625F;
        float var8 = 0.00390625F;
        Tessellator var9 = Tessellator.instance;
        var9.startDrawingQuads();
        
        var9.addVertexWithUV((double)(par1 + par5), (double)(par2 + 0), (double)this.zLevel, (double)((float)(par3 + par5) * var7), (double)((float)(par4 + 0) * var8));
        
        var9.addVertexWithUV((double)(par1 + par5), (double)(par2 + par6), (double)this.zLevel, (double)((float)(par3 + par5) * var7), (double)((float)(par4 + par6) * var8));
        
        var9.addVertexWithUV((double)(par1 + 0), (double)(par2 + par6), (double)this.zLevel, (double)((float)(par3 + 0) * var7), (double)((float)(par4 + par6) * var8));
        
        var9.addVertexWithUV((double)(par1 + 0), (double)(par2 + 0), (double)this.zLevel, (double)((float)(par3 + 0) * var7), (double)((float)(par4 + 0) * var8));
        var9.draw();
        
    }

}

 

 

This code allows to update the GUI in the other 4 directions:

• decrease x, increase y
  
• increase x, decrease

Nice!
