I'm trying various things whilst modding and thought it would be fun to create a new health bar, like the one found in Diablo 2.

The problem is the food bar doesn't render it's textures.

 

Both the code for the Gui class, which is what seems to be breaking the food bar when calling renderHealthBar(), and the code from where I call the method is found below.

 

GuiRPGHealth.java

Spoiler

public class GuiRPGHealth extends Gui {

    private static final Minecraft mc = Minecraft.getMinecraft();

    private final int healthGlobeWidth = 60;
    private final int healthGlobeHeight = 60;

    private static final ResourceLocation GUI_RESOURCES = new ResourceLocation(Reference.MOD_ID, "textures/gui/hud/health_globe.png");

    public void renderHealthBar() {

        EntityPlayerSP player = mc.player;

        float healthMax = player.getMaxHealth();
        float healthCurr = player.getHealth();
        float healthPercent = healthCurr/healthMax;

        ScaledResolution scaledResolution = new ScaledResolution(mc);

        int containerCornerX = 20;
        int containerCornerY = scaledResolution.getScaledHeight()-healthGlobeHeight-20;

        mc.getTextureManager().bindTexture(GUI_RESOURCES);

        GlStateManager.enableBlend();

        this.drawTexturedModalRect(containerCornerX, containerCornerY, 60, 0, healthGlobeWidth, healthGlobeHeight);

        int offset = (int) (healthGlobeHeight-(healthGlobeHeight*healthPercent));

        this.drawTexturedModalRect(containerCornerX, containerCornerY + offset, 0, offset, healthGlobeWidth, (int) (healthGlobeHeight*healthPercent)+1);

        GlStateManager.disableBlend();

        String healthText = (int)healthCurr+"/"+(int)healthMax;

        GL11.glPushMatrix();
        GL11.glScalef(1.2f, 1.2f, 1.2f);
        this.drawCenteredString(mc.fontRenderer, healthText, containerCornerX + healthGlobeWidth/2, containerCornerY + healthGlobeHeight/2-mc.fontRenderer.FONT_HEIGHT, 0xffffffff);
        GL11.glPopMatrix();
    }
}

 

RPGHud.java

Spoiler

public class RPGHud extends Gui {

    private static GuiRPGHealth guiRPGHealth = new GuiRPGHealth();

    private static void renderRPGHud(float partialTicks) {
        guiRPGHealth.renderHealthBar();
    }

    @SubscribeEvent
    public static void afterRenderGui(RenderGameOverlayEvent.Post event) {
        renderRPGHud(event.getPartialTicks());
    }

    @SubscribeEvent
    public static void onRenderGui(RenderGameOverlayEvent.Pre event) {
        if(event.getType() == RenderGameOverlayEvent.ElementType.HEALTH) {
            event.setCanceled(true);
        }
    }
}

 

 

And the RPGHud is registered on the event bus, on the client side.

 

Thank you in advance!

Once you're done rendering you need to bind the ICONS resource because it expects it.

Fantastic, thank you so much for the help.

If you have time, could you answer what the best way is to disable the rendering of the original healthbar?

Right now I use the event to check if the ElementType is of HEALTH, as can be seen in RPGHUD.java above.

 

But I can see you can set

GuiIngameForge.renderHealth = false;

which I tried in my FMLPostInitializationEvent for the client side, and this seems to work. But does one of them have a downside, which should deter me from using them?

Use the event.

Alright, thank you for your time, and have a great day.
