[1.10.2] [UNSOLVABLE] Make the player light like a torch?

[Differentiation]

Hey,
So I wanted to make an armor piece that, when worn, it will light the player up (like a torch...)

is there a way to do that?

Please leave your ideas below!

Thanks!

No.

The best way to go about this is creating a block that is for all intents and purposes, air, but emits light. And then placing/removing them as the player moves.

 

And it will lag like a mofo.

Oh, I guess not...

Thanks though

Why did you say "I guess not" when he just told you how to do it?

 

I did it exactly the way draco said and made the player emit light (in my case I only turned it on when holding a light emitting item, but you could do exactly the same when wearing an item).

 

See my video here:

I've also done it. And I limited lighting updates to only move the light emitting block only once the player was a sufficient distance away from it (in my case 3 or 4 blocks).

I mean, I see the point, but teleporting the block to the player every tick may lower the FPS and many people's computers can't handle that.

Can I have a look at the tutorial for this (if you have one?)

Thanks!

Moving the block isn't the lag inducing part, its the lighting update.

Unfortunately, the torch gives light as a block, whereas (in programming terms) a player is an entity + itemstacks in various inventory slots. That's why the proposed solutions involve unseen blocks.

 

That reminds me, my own to-do list includes a helmet with a miner's lamp on it (or I might do a helm enchantment).

How does Optifine handle its dynamic lighting? I believe they do it purely client-side, and from what I've seen performance is pretty good.

It's client side only, AFAIK. And because of that, it can be more efficient, as lighting (as a mechanic) requires altering data values that are used to validate spawn locations for mobs.

I do actually have entities in my mod that emit light without an invisible block. I will admit it is by far from the best way and can cause large amounts of lag if you have several of them, but the FPS drop isn't noticeable for only a few of them.

 

Here is the code I use for it. I STRONGLY recommend trying to make sense and understanding it before using it otherwise you can easily cause the game to break an cause large amounts of lag. I do not know how well it will work around a player, but I would expect it would be fairly easy to get it to work. I provide this so you can study it and understand it, not as something you can simply copy and paste.

Here is source code: https://github.com/jabelar/MovingLightSource-1.12

 

Note in that mod entities on fire also become moving light sources, so kind of fun to set the time to night and light them up -- and for fun I make torches weapons that can set entities on fire.

 

In terms of performance, perhaps you should also consider what Draco is mentioning. However, performance is a relative thing and I have the luxury of playing on good gaming rigs and it is quite smooth (you can see in my video), and everyone's computers are getting better every day (just go buy a NVIDIA mid-range GeForce card and you'll do fine) so I'm not sure how much it is worth looking at.

Thanks! I'll definitely have a look.
