Hi everyone,

 

I want to change the HUD inventory Rendering by replacing the gui temporarily to simulate swapping of inventories. If your ead my other post I successfully manipulated the vanilla hud inventory to essentially be a different inventory that is triggered based on a condition. I was wondering about the HUD rendering, how would I replace the GUI of the inventory HUD with my own custom one based on a condition that is set in my players IEEP class.

 

if condition is true -> render my custom HUD inventory

if condition is false -> render default vanilla inventory hud

Ive been looking for the code and I have no idea where the vanilla HUD inventory renders

GuiIngameForge in 1.8, not sure about 1.7

Hi everyone, So I figured out how to get it to show up.

 

But there is a problem, whenever I resize the window the gui doesnt stay in the spot I place it. Not sure why.

protected void renderHotbar(int width, int height, float partialTicks)
    {
        
        mc.mcProfiler.startSection("actionBar");
        GL11.glEnable(GL11.GL_BLEND);
        GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
        GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        mc.renderEngine.bindTexture(itemHUDTexture);

        InventoryPlayer inv = mc.thePlayer.inventory;
        drawTexturedModalRect(width/2 + 140, height/2 + 200, 0, 0, 182, 22); <--- draws the custom hotbar I made
        drawTexturedModalRect(width/2 +140 +inv.currentItem * 20, height/2 + 200, 0, 22, 24, 22); <--- draws the gui overlay  that shows which item is selected

        GL11.glDisable(GL11.GL_BLEND);
        GL11.glEnable(GL12.GL_RESCALE_NORMAL);
        RenderHelper.enableGUIStandardItemLighting();

        for (int i = 0; i < 9; ++i)
        {
            int x = width / 2 + i * 20 + 2;
            int z = height;
            renderInventorySlot(i, x, z, partialTicks);
        }

        RenderHelper.disableStandardItemLighting();
        GL11.glDisable(GL12.GL_RESCALE_NORMAL);
        mc.mcProfiler.endSection();
       
    }

But whenever I resize the window the gui jumps around. Any idea why?

 

I call this method in the

 

public void RenderBattleGUI(RenderGameOverlayEvent.Post event)

 

if(myCondition){
int width = event.resolution.getScaledWidth();
int height = event.resolution.getScaledHeight();
renderHotbar(width, height, 1);
}

you should be looking how vanilla caluclates those values.. then u will get the same results

You need to create a ScaledResolution (look at the source code using your IDE) object and get the scaled width / height from there. After that, divide both the width and height by 2 (getting the exact center of the screen based on its resolution) and then add / subtract from there. Pure math.
