Heres my gui code... it puts the GUI in the top left and not in the center

 

 

package kore.korecraft.mod;

 

import net.minecraft.client.gui.GuiButton;

import net.minecraft.client.gui.inventory.GuiContainer;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.entity.player.InventoryPlayer;

import net.minecraft.util.StatCollector;

 

import org.lwjgl.opengl.GL11;

 

public class GuiExpBank extends GuiContainer {

 

private TileEntityExpBank expbank;

 

        public GuiExpBank (InventoryPlayer inventoryPlayer,

        TileEntityExpBank tileEntity) {

        //the container is instanciated and passed to the superclass for handling

        super(new ContainerExpBank(inventoryPlayer, tileEntity));

        expbank = tileEntity;

        }

 

        @Override

        protected void drawGuiContainerForegroundLayer(int param1, int param2) {

        //draw text and stuff here

        //the parameters for drawString are: string, x, y, color

        fontRenderer.drawString("Exp Bank", 8, 6, 4210752);

          //draws "Inventory" or your regional equivalent

      fontRenderer.drawString(StatCollector.translateToLocal("container.inventory"), 8, ySize - 96 + 2, 4210752);

        }

 

        @Override

        protected void drawGuiContainerBackgroundLayer(float par1, int par2,

                        int par3) {

                //draw your Gui here, only thing you need to change is the path

                int texture = mc.renderEngine.getTexture("/Korecraft/GUI/ExpBank.png");

                GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);

                this.mc.renderEngine.bindTexture(texture);

                int x = (width - xSize) / 2;

                int y = (height - ySize) / 2;

                this.drawTexturedModalRect(x, y, 0, 0, xSize, ySize);

        }

       

        public void initGui() {

    this.controlList.clear();

 

    int posX = (this.width - xSize) / 2;

    int posY = (this.height - ySize) / 2;

 

    GuiButton button1 = new GuiButton(0, 15, 70, 20, 10, "- 10");

    GuiButton button2 = new GuiButton(1, 40, 70, 20, 10, "- 1");

    GuiButton button3 = new GuiButton(2, 65, 70, 20, 10, "+ 1");

    GuiButton button4 = new GuiButton(3, 90, 70, 20, 10, "+ 10");

 

    this.controlList.add(button1);

    this.controlList.add(button2);

    this.controlList.add(button3);

    this.controlList.add(button4);

    }

   

    public void actionPerformed(GuiButton button)

    {

    switch(button.id)

    {

    case 0:

    default:

    }

    }

}

 

 

int x = (width - xSize) / 2;
int y = (height - ySize) / 2;
this.drawTexturedModalRect(x, y, 0, 0, xSize, ySize);

 

What are the values of width, height, xSize and ySize?

they should be just the height and width of the gui
