I can't seem to get anything to render on the screen. I have the mana working but can't make a bar or even just the int display. I am not good with rendering anything.

I tried a few different things that all didnt work. Right now I have nothing but what I had that seemed most likely to work was just a guiOverlay.blit(x, y, z, vx, vy, getMana()). I dont remember the exact code but it was somthing along those lines.

It was in a new class extending screen I believe.

This is my latest attempt :ย 

public class ManaScreen extends Screen {

    Mana mana = new Mana();

    boolean removeManaBar = false;

    ResourceLocation manaBar = ResourceLocation.fromNamespaceAndPath(RSGArmoury.MOD_ID, "/textures/block/spawnable_arena_wall.png");

    public ManaScreen() {
        super(Component.literal("Mana"));
    }

    @Override
    protected void init() {
        super.init();
        Minecraft.getInstance().setScreen(this);
    }

    @Override
    public boolean isPauseScreen() {
        return false;
    }

    @Override
    public void render(GuiGraphics pGuiGraphics, int pMouseX, int pMouseY, float pPartialTick) {
        pGuiGraphics.blit(manaBar, 10, -10, 0, 0, mana.getMana(), 10, mana.getMana(), 10);

        if (removeManaBar) {
            this.onClose();
            return;
        }

        super.render(pGuiGraphics, pMouseX, pMouseY, pPartialTick);
    }

    public void addManaBar() {
        removeManaBar = false;
        Minecraft.getInstance().setScreen(new ManaScreen());

    }

    public boolean removeManaBar() {
        return removeManaBar = true;
    }

}

If you want a mana GUI, call Minecraft.getInstance().setScreen(new ManaScreen());

somewhere display your GUI.

I would recommend creating a keybind and listening to key events, and if your key bind is pressed down, running that code.

Ok, sounds likeย I would probably be best with a overlay then. I have also tried to make an event that setScreens when a magic item is pulled out and I think it actually crashed the game.

If you set the screen when the item was pulled out that would make the item partially unusable. You canโ€™t move in game when your screen isnโ€™t null.

Ok, I see so a screen is only really useful for like a menu but would that explain the crashing? I haven't attempted making an overlay yet. By the way is there a way to get a notification from this site? I only check in every once in a while when I remember to see if there was an update.

As I sent that it gave me a push notification pop up lol.

To explain the crashing I need to see the log. Also, if you want to follow the topic just scroll to the top and click the following thing, and then press follow.

And yes, screen are really only useful for menus and things.

This is what I have now, nothing shows on the screen and after using mana the game freezes.

ย 

public class ManaOverlay extends Overlay {
    ResourceLocation manaBar = ResourceLocation.fromNamespaceAndPath(RSGArmoury.MOD_ID, "/textures/block/spawnable_arena_wall.png");

    @Override
    public void render(GuiGraphics pGuiGraphics, int pMouseX, int pMouseY, float pPartialTick) {
        Mana mana = new Mana();

        pGuiGraphics.blit(manaBar, 16, -16, 0, 0, mana.getMana(), 16, mana.getMana(), 16);

    }

    @Override
    public boolean isPauseScreen() {
        return false;
    }
}
