Overlay that appears briefly during potion effect
Sun, 06/07/2020 - 02:09

I am trying to make a potion effect that will randomly flash an image (an Overlay?) for about a second. ideally with 4-6 different images that just briefly appear at random while effected. i am not sure how to bind multiple overlays to a potion effect, nor how to make them go away after a short time. is there a procedure to make overlays appear?

I can help you code it if you want unless you are able to do it in MCreator.

Override a method? Just subscribe to RenderGameOverlayEvent.Pre, or maybe I am not understanding what you mean.

I took some time; wrote up and tested this code (you can condense it I am sure, my excuse is that I am a little tired and rushed lol).

    private int tick;
    private int overlayUp;
    private Random random = new Random();
    private int randomOverlay = 3;
    private boolean isOverlayUp = false;
    @SubscribeEvent
    public void renderOverlay(RenderGameOverlayEvent.Post event) {

        if (event.getType() == RenderGameOverlayEvent.ElementType.TEXT) {
            Minecraft mc = Minecraft.getInstance();
            mc.textureManager.bindTexture(notifs);
            AbstractClientPlayerEntity abstractClientPlayerEntity = mc.player;
            Collection<EffectInstance> effectsList = abstractClientPlayerEntity.getActivePotionEffects();
            Iterator iterator = effectsList.iterator();
            System.out.println(effectsList);
            while (iterator.hasNext())
            {
                EffectInstance effect = (EffectInstance) iterator.next();
                if (effect.getPotion() == Effects.SPEED)
                {
                    tick++;
                    if (tick >= (20 * 6))
                    {
                        tick = 0;
                        isOverlayUp = true;
                        randomOverlay = random.nextInt(3);
                    }
                    if (isOverlayUp) {
                        if (randomOverlay == 2) {
                            overlayUp++;
                            if (overlayUp >= 20) {
                                overlayUp = 0;
                                isOverlayUp = false;
                            }
                            mc.ingameGUI.blit(5, 8, 0, 0, 16, 16);
                        } else if (randomOverlay == 1) {
                            overlayUp++;
                            if (overlayUp >= 20) {
                                overlayUp = 0;
                                isOverlayUp = false;
                            }
                            mc.ingameGUI.blit(5, 20, 0, 16, 16, 16);
                        } else if (randomOverlay == 0) {
                            overlayUp++;
                            if (overlayUp >= 20) {
                                overlayUp = 0;
                                isOverlayUp = false;
                            }
                            mc.ingameGUI.blit(5, 10, 0, 32, 16, 16);
                        }
                    }
                }
            }

@Calazaks: Keep in mind, you should understand the blit parameters and can change the effects to whatever you want ;D.

 

 

Also, before I post this. This code is based on framerate which is very "bad". So to get a consistent "timer" for each player. Subscribe to ClientTickEvent and set NBT variables for the timers and such. If you need more of an explanation/code, I would be thrilled to help you with that. I guess that is it.

To further elaborate as to what i'm trying to make, i'm attempting to make a "Madness" potion effect that has a ton of random things that occur, and i think that strange images randomly appearing almost like a jumpscare would add a bit more appropriate "mental" themes

Absolutely

 

To extend on my code, it is optimized for 3 images. However, you can append the integers to get more, again if you need help post code or just ask🤗🤗🤗
