how to render aura around player [1.15.2]

Recommended Posts

So, I've made a procedure for activating an aura around the player when they hit a certain key. (R and X to be exact) They do certain things too, but as of now, they only release this buggy custom particle that I made which looks trashy in the long run and I wouldn't want that to be what the aura looks like when I upload the actual release of the mod. I've seen this exact topic before, but in 1.12.2, and when I asked if he'd figured it out, the topic was archived because of support no longer going to 1.12.2, which I don't use anyway, so it's fine.

As said in that post, I too would love the aura to look like this. Also, they gave the link to an outdated resource at https://greyminecraftcoder.blogspot.com/2014/12/the-tessellator-and-worldrenderer-18.html. The author of the topic seemed to understand how to do it and said he'd update if he had any problems understanding. He never posted again, so I'm wondering if he figured it out. The topic that was used in the link was for making a block I believe, but I'm trying to make a particle that looks like that and comes off the player in all directions. Basically, the aura I have only comes out in the player's direction, which I can't seem to fix, and so when I make multiple particles spawn, it doesn't encompass the player like the aura in the picture and just looks like multiple auras side by side. If I could get any help, that would be amazing! I'm terrible at coding, so if there's a slow paced reply, that would be great, and also if you could tell me where to insert the code portion. Thanks again!

I'm only quoting so that you receive a notification, because normally replies don't notify for some reason.

Anyway Your best bet to create an aura would be a render overlay like how the player is on fire, and activate it from a RenderLivingEvent: 

@Mod.EventBusSubscriber(modid = Main.MOD_ID)
public class ForgeSubscribeEvents {

  @SubscribeEvent
  public void onRenderEntity(RenderLivingEvent.Post event) {
      //code here
  }
}

In the event you'll handle pushing and popping the render matrix stack, which is what the post on greyminecraftcoder is talking about, despite being a bit outdated. I've tried tackling it here in 1.16.X but with little success. 

It might be easier to go the particle route if you still want to do that though. This would be handled by a LivingUpdateEvent which you've probably already done:

@SubscribeEvent
public static void onLivingUpdate(final LivingEvent.LivingUpdateEvent event) {
	//code here
}

However bending which way the particles face as per the link so that they're concentric to the player would still likely involve the matrix stack.

    • My name is SARAH GOLDFISH, and I'm the CEO of a once-thriving tech startup. Today, I want to share a deeply personal story about how Tropical Delight Recovery saved my business and, quite possibly, my life. In the summer of 2023, my company was at its peak. We had just secured a major partnership, our products were flying off the shelves, and our future looked brighter than ever. However, in the midst of this success, I made a decision that nearly led to our downfall.  Like many others, I was drawn to the world of cryptocurrency. The promise of quick and significant returns was enticing, and I saw it as an opportunity to further bolster our financial standing. After some research, I invested a substantial amount of the company’s funds into a new and seemingly promising cryptocurrency. At first, it seemed like a great move. The value of our investment soared, and I was hailed as a visionary. But as quickly as our fortunes rose, they plummeted. The cryptocurrency market is notoriously volatile, and within weeks, the value of our investment tanked. What I had failed to see was that the currency was part of a sophisticated scam. The entire platform vanished overnight, and with it, our hard-earned money. The impact was immediate and devastating. Our financial cushion was obliterated, and we found ourselves unable to meet payroll or fulfill orders. Our partners began to lose faith, and the media caught wind of our predicament, amplifying our troubles. I was overwhelmed with guilt and fear. I had not only jeopardized the company but also the livelihoods of my employees. Despair set in, and I couldn't see a way out. In my darkest hour, a friend recommended Tropical Delight Recovery. Skeptical and with little hope, I reached out to them. From the first contact, their team was professional, understanding, and, most importantly, optimistic about our chances of recovery. They assured me that they had dealt with similar cases and had a strong track record of retrieving lost funds from fraudulent schemes. Tropical Delight Recovery took swift action. They meticulously traced the fraudulent transactions and employed their extensive network and legal expertise to go after the perpetrators. Their process was transparent, and they kept me informed at every step. It was a complex and arduous journey, but their determination never wavered. Weeks turned into months, and just when I was starting to lose hope, Tropical Delight Recovery delivered a miracle. They managed to recover a significant portion of our lost funds. The relief I felt was indescribable. This wasn't just about the money; it was about the restoration of hope and the possibility of a future for my company. With the recovered funds, we were able to stabilize our finances, reassure our partners, and regain the trust of our employees. It wasn't an instant fix, but it gave us the lifeline we needed to rebuild. Slowly but surely, we started to turn things around. Today, our company is back on track, stronger and more resilient than ever. I owe a debt of gratitude to Tropical Delight Recovery. They didn't just save my company; they saved me from a path of despair and hopelessness. Their professionalism, expertise, and unwavering commitment to their clients make them a beacon of hope for anyone caught in the web of financial fraud. If you find yourself in a situation like mine, don't hesitate to reach out to Tropical Delight Recovery. They are more than a recovery company; they are life-savers.
