Hello everyone, 

I want to render the Inventory Player to the main Menu but it makes problems.

It makes Problems here:

 

public static void drawEntityOnScreen(int x, int y, int scale, float mouseX, float mouseY, EntityLivingBase entity)
    {
        GlStateManager.enableColorMaterial();
        GlStateManager.pushMatrix();
        GlStateManager.translate((float)x, (float)y, 50.0F);
        GlStateManager.scale((float)(-scale), (float)scale, (float)scale);

        entity.rotationYaw = var7;

        GlStateManager.func_179090_x();
        GlStateManager.setActiveTexture(OpenGlHelper.defaultTexUnit);
    }

 

In GuiMainScreen i gave it so:

 

EntityLivingBase elb = mc.thePlayer;

[...]

GuiInventory.drawEntityOnScreen(ex, ey, 30, (float)(ex) - GuiInventory.oldMouseX, (float)(ey) - GuiInventory.oldMouseY, elb);

That is null until you join a world... I think

But what is mc?

mc is Minecraft(). Isnt there a possibility that i can render it ? Has somebody a workaround?

I guess Minecraft.getMinecraft()?

Also, can you show your full code instead of little pieces?

Here is the Part where it is called (GuiMainMenu)

 public void initGui()
    {
    	int sx = (int) (width * 0.025);
    	int sy = (int) ( height * 0.25);
    	int ex = width / 2 - 150;
    	EntityLivingBase elb = mc.thePlayer;
    	EntityPlayerSP player = new EntityPlayerSP();
    	int ey = height / 2 - 150;
    	int swidth = 80 * (int) (width / 427.0);
    	int sheight = 150 * (int) (height / 150.0);
    	updateList = new GuiScrollList(sx, sy, swidth, sheight, 1073741823, "Updates", InfoUpdates.lines, true);
    	GuiInventory.drawEntityOnScreen(ex, ey, 30, (float)(ex) - GuiInventory.oldMouseX, (float)(ey) - GuiInventory.oldMouseY, player);
    	[...]
}

 

How do you make that?  I would make to it also a Skin

Jay, I said something right

But how

But how? Pls say it

How do you know what inventory to render? Each save has a different player profile, with a different inventory...

No i ment the Player left above the inv.

That makes more sense... Look at how it's done in the Inventory Gui. That could give you a hint. I have never personally done this myself, as I am not skilled in rendering (I have had a LOT of trouble with simple directional blocks... :P), but I believe that the Inventory Gui has the code for rendering the player. Just use that with a fake player. Basically, FakePlayer fakePlayer = new FakePlayer(argumentsHere);

FakePlayer requires a world argument, and if it's null, it will output an NPE.

Yes, but even when i render it in the world it gives me a black screen if i have something in the hand .-.
