drawTexturedModalRect() get a purple square

[Zee]

As title, when I use drawTexturedModalRect(), it draw a purple square on the screen. Could anyone tell me what's wrong with my code?

public class playInventoryLockGUI extends GuiInventory {
    
    final ResourceLocation icon_party = new ResourceLocation(Reference.MODID, "textures/icon_party.png");
        
    int u = 1;
    int v = 1;
    
    public playInventoryLockGUI(EntityPlayer player)
    {
        super(player);
    }
    
    @Override
    public void drawScreen(int mouseX, int mouseY, float partialTicks)
     {
         super.drawScreen(mouseX, mouseY, partialTicks);     

         this.mc.renderEngine.bindTexture(icon_party);
         GlStateManager.color(2.0f, 2.0f, 2.0f);
         GlStateManager.pushMatrix();
         {
            GlStateManager.scale(0.5f, 0.5f, 1f);      
            drawTexturedModalRect(200, 200, u, v, 26, 26 );
         }
         GlStateManager.popMatrix();
     }     
}

I think you need to add .png

What happens if you remove this line? What happens if you change it to 1.0f, 1.0f, 1.0f?

(May not be useful right now, but once you've solved the missing texture problem...)

I already try that. It does not fix the texture.
 i add this line because, there was a drawString() before drawTexturedModalRect().
This is how i call this playInventoryLockGUI:

    public void onOpenGUI (GuiOpenEvent event)
    {
        GuiScreen gui = event.getGui();
        
        if ( (gui instanceof GuiInventory) && (!(gui instanceof playInventoryLockGUI))){
            gui = new playInventoryLockGUI(Reference.mc().thePlayer);    
            event.setGui(gui);    
        }
    }

The only other thing I can think of is to check whether the texture really exists in src/main/resources/assets/<modid>/textures/icon_party.png, check the spellings exactly, make sure your mod ID is all lower case, and refresh the folder so the IDE knows it's there.

If none of those work, I'm at as much of a loss as you are.

I double check the path, there is not problem with that. but i solve it. thx all.
problem is here:

ResourceLocation icon_party = new ResourceLocation(Reference.MODID, "textures/icon_party.png");

Should be:

ResourceLocation icon_party = new ResourceLocation ( Reference.MODID + ":textures/icon_party.png");
//or
ResourceLocation icon_party = new ResourceLocation ("<modid>:textures/icon_party.png");
