[1.10.2] [OpenGL] rendering rectangles and overlay?

[Cleverpanda]

Hello. I've got an overlay being rendered that only fills part of the screen, and I'd like to draw black rectangles around the other parts to cover them up.

 

GL11.glPushMatrix();
    mc.renderEngine.bindTexture(overlay);
    GL11.glScalef(scalefact,scalefact, 1);

    this.drawTexturedModalRect(xPos, 0, 0, 0, 256, 256);
   
    this.drawRect(0, 0, xPos, screenHeight, 0);
    this.drawRect((int) (xPos+scalefact*256), 0, screenWidth, screenHeight, 0);
    GL11.glPopMatrix();

I'm not experienced with openGL but the code so far does this:

And I'm not sure why it does nothing about my two rectangles...

Show the whole code...

Screen.width - 265 -> size of the rest of the screen not covered.

 

I'm sure you can work out the rest.

[Cleverpanda]

No, I don't think I will.. and I don't think the translations are the issue.
Even when I just do 

 

    GL11.glPushMatrix();
    this.drawRect(0, 0, screenWidth, screenHeight, 0);
    GL11.glPopMatrix();

 

and nothing else for the rendering, it does not make a rectangle...

Bipity bopity bump.

Your color is 0. That means the alpha is 0 too. The drawRect method want a ARGB-Value:

"0xFF000000"

That would be a black color with a alpha of 1.0F.

Okay, I see that the method takes an int and shifts to get rgb and alpha, but the int value of that would be 4278190080, which is out of range.. So i'm going to assume the alpha bits are last? lets see

No, thats rubbish logic...

I copied the drawrect method but just gave GlStateManager.color() inputs manually. works fine

Color is an unsigned integer.
