Hi guys,

 

I have a problem with rendering a GUI and I've exhausted all debugging options I can think of, so i thought someone here might have an idea.

 

The problem is that I'm trying to render a dynamically sized tank, but Minecraft isn't displaying anything (not even the super simple drawRect rectangle).

 

This is the relevant code:

 

   

@Override
    public void render(Minecraft minecraft, int offsetX, int offsetY, int mouseX, int mouseY) {
        //Gray Background
        drawRect(offsetX + x, offsetY + y, offsetX + x + width, offsetY + y + height, Colors.DARK_GRAY);

        //Fluid Level
        if(fluid != null) {

        }

        minecraft.getTextureManager().bindTexture(Textures.Gui.MACHINE_ELEMENTS);

        //Foreground
        //right side
        int xStart = width - 3;
        int newHeight = height - 2;
        for(int i = 0; i < newHeight / 2; i++) {
            drawTexturedModalRect(offsetX + x + xStart, offsetY + y + 1 + (newHeight % 2) + (i * 2), 1, 7, 3, 2);
        }
        //top border
        xStart = width - 4;
        drawTexturedModalRect(offsetX + x + xStart, offsetY + y, 0, 6, 4, 1);
        for(int i = 0; i < xStart; i++) {
            drawTexturedModalRect(offsetX + x + i, offsetY + y, 0, 6, 1, 1);
        }
        //bottom border
        drawTexturedModalRect(offsetX + x, offsetY + y + height - 1, 0, 9, 4, 1);
        for(int i = 4; i < xStart + 4; i++) {
            drawTexturedModalRect(offsetX + x + i, offsetY + y + height - 1, 1, 9, 1, 1);
        }
        //left border
        if(newHeight % 2 != 0) drawTexturedModalRect(offsetX + x, offsetY + y + 1, 0, 7, 1, 1);
        for(int i = 0; i < newHeight / 2; i++) {
            drawTexturedModalRect(offsetX + x, offsetY + y + 1 + (newHeight % 2) + (i * 2), 0, 7, 1, 2);
        }
    }

 

You can find the full project here: https://github.com/Todkommt/Mass-Effect-Ships-Mod

And this is the only usage of this class (GuiComponentFluidGauge.java): GuiDeuteriumExtractor.java

Theres also this extremely similar component that works perfectly fine: GuiComponentEnergyGauge.java

 

Some extra debug info:

The coordinates are translated to the space of a root object (so x = 63 means 63 from the top left corner of the gui screen, not the minecraft window)

 

offsetX = 0

offsetY = 0

x = 63

y = 8

width = 14

height = 42

Colors.DARK_GRAY = 0x8B8B8B

zLevel = 0

 

Any help would be greatly appreciated =)

Does no one have any idea? I'm really getting frustrated at the fact that I can't fix this problem

Still haven't found a solution bump

Is this simply a GuiScreen or, a GuiContainer?

Is this simply a GuiScreen or, a GuiContainer?

 

It's an OpenModsLib BaseComponent (which extends Gui). It's being called from a GuiContainer.

Is the render method being called?

Yes, the variable values I posted in the OP are taken from a breakpoint at the drawRect call.
