I made a tileEntity, a container, a guiHandler, everything needed but the Gui just glitches. I can't see the text box when my mouse is over the items, and there's no darker background when opened. Can somebody tell me, what's the problem?
Here's my code:

package net.gml.mod.block.specific_blocks.assembler;

import net.minecraft.client.gui.inventory.GuiContainer;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.resources.I18n;
import net.minecraft.entity.player.InventoryPlayer;
import net.minecraft.inventory.Container;
import net.minecraft.util.ResourceLocation;
import net.gml.mod.gmlMod;
import net.gml.mod.block.ModBlocks;

public class GuiAssembler extends GuiContainer {

    private static final ResourceLocation BG_TEXTURE = new ResourceLocation(gmlMod.modId, "textures/gui/assembler.png");
    private InventoryPlayer playerInv;

    public GuiAssembler(Container container, InventoryPlayer playerInv) {
        super(container);
        this.playerInv = playerInv;
    }

    @Override
    protected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY) {
        GlStateManager.color(1, 1, 1, 1);
        mc.getTextureManager().bindTexture(BG_TEXTURE);
        int x = (width - xSize) / 2;
        int y = (height - ySize) / 2;
        drawTexturedModalRect(x, y, 0, 0, xSize, ySize);
    }

    @Override
    protected void drawGuiContainerForegroundLayer(int mouseX, int mouseY) {
        String name = I18n.format(ModBlocks.assembler.getUnlocalizedName() + ".name");
        fontRenderer.drawString(name, xSize / 2 - fontRenderer.getStringWidth(name) / 2, 6, 0x404040);
        fontRenderer.drawString(playerInv.getDisplayName().getUnformattedText(), 8, ySize - 94, 0x404040);
    }
}

 

Bump. Please?

If you want to have the tinted background and the tooltips display override the drawScreen method:

	@Override
	 public void drawScreen(int mouseX, int mouseY, float partialTicks) {
		this.drawDefaultBackground(); //Add this
		super.drawScreen(mouseX, mouseY, partialTicks);
		this.renderHoveredToolTip(mouseX, mouseY); //Add this
	 }

 

Thanks!
