Melee Friendly Ender Dragon Fight

[violet rivet]

oooo are you redoing the dragon fight??

[heady plaza]

Yeah
It's specifically for my mod Dungeons Perspective, because the mod puts you in top down perspective where normal ender dragon fight is difficult
It will release on Curseforge when it's done, hopefully soon

[violet rivet]

sounds amazing!

[main vine]

Cool, how does mining work?

[heady plaza]

It's a bit difficult due to not being able to see up, but in general the mouse is accurate enough to mine properly

[harsh vault]

are we gonna get it to land or occasionally hover in place so we can fight it skyrim style

[woven frost]

oh this seems kind of similar to my mod Minecraft XIV. i'm curious about how you're doing culling to avoid the camera being able to see things it shouldn't, like adjacent caves

[heady plaza]

Your mod is actually the basis for my mod!

Heavily modified

[woven frost]

oh, amazing :D

[heady plaza]

Please let me know if you have an issue with that

I figured you wouldn't because I looked at the license

[woven frost]

well it should definitely mention my mod in the description and i'd have appreciated an email about you using it lol but it's allowed

maybe we can collaborate though

[heady plaza]

My bad, I mention it in the mod page I believe

[heady plaza]

I can give you the way I do culling! It's a mess of mixins but is getting refined as time goes on

[woven frost]

yeah i'd love to know. does your mod have the camera avoid terrain at all or is it handled entirely by the culling?

[heady plaza]

It's handled entirely by the culling
Recently, I made advancements to it to make it more visually appealing

This is how it looks now

[woven frost]

oh that's a lot like the uh psychonauts effect that i was told about by some other people lol

really nice looking

I made a modpack in this perspective, with the inspiration being more Diablo and Path of Exile

[woven frost]

WOW

pretty neat

oh so you use a flood fill algorithm for culling? that's basically what i was considering

i guess with a top down perspective you don't have artifacts like the yellow regions in this image?

[heady plaza]

Some of those artifacts would still be shown, but the red portion shouldnt be shown because I force terrain past a certain distance underground to not render, via mixin

[woven frost]

ohh i thought the red part was handled by the flood fill

ah and i see you fixed the issue with the sound being relative to the camera not the entity :D

[woven frost]

or at least i thought that's what was going on

[woven frost]

oh so this is done by culling, i was wondering if it'd be possible to get a stippled translucency effect by rendering those blocks in a separate pass but i don't think that's easy to do

and the custom culling is why it requires sodium?

[heady plaza]

Yes, sodium is required for the culling

Actually thats wrong
You can do native culling, but installing sodium breaks it
For that reason I just make sodium mandatory and deal just with that

[woven frost]

okay so i could include two mixins and choose between them at runtime

[heady plaza]

Yeah that would work

[woven frost]

do you know if there's a way to render a second pass with just the culled faces?

and then i could composite it with translucency into the final render

[woven frost]

hmmm i just had a thought

we could render the blocks in between as wireframes

we would have to be careful to make sure the blocks around the player are not occlusion culled but then in the renderer itself we could simply make it only render the outer 1px of any blocks within a cone outward from player to camera

[woven frost]

i'm struggling to figure out exactly how to do it but this is definitely possible with shaders

[woven frost]

like this :3

though i don't actually really like this look, but it's easy to change. just gotta pipe in the player coords so i can do the cone filtering

[jagged creek]

holy xray

[woven frost]

stippled translucency

[woven frost]

or maybe big stipple

tho that could use some downsampling or smth

ideally the dots are one color per

[heady plaza]

Thats really nice!

[heady plaza]

Are you renderering it twice, and overlaying the second one as a circle?

[woven frost]

no, this is all done in the sodium fragment shader

[heady plaza]

And it uses the block culling method I use to select which blocks to cull?

[woven frost]

nope

[heady plaza]

Wow that should perform a lot better then

[woven frost]

yep

looks a lot better if i may say so myself

[heady plaza]

Yeah, is there a way to simply remove the blocks with no wireframes at all?

I think it would look good that way

[woven frost]

i mean sure but i like the wireframes

[heady plaza]

I didnt think of using shaders to accomplish this

[woven frost]

especially with the texel level stippling

[heady plaza]

Is this just a shader?

[woven frost]

yep

[heady plaza]

Damn I should get into making shaders then

I assume it wont work with other shaders?

[woven frost]

yep

[heady plaza]

So you'd have to modify shaders specifically to work with this view

[woven frost]

i'm just mixing into sodium's shader loader and replacing the opaque block shader

it's rather minimal and you could probably easily support it for vanilla shaders as well

[heady plaza]

So - it does work with other shaders? Like complementary?

[woven frost]

no, iris uses a completely different system

it replaces sodium's renderer i think

[heady plaza]

Ah I see

So this isnt compatible with Iris

[woven frost]

you could write an iris shader too i'm sure

[heady plaza]

Still, very impressive

[woven frost]

but it would be harder to share code

[heady plaza]

Yeah that'd definitely be possible

Your idea of rendering it once without the occluding blocks, and then again with, stippled might accomplish the same thing though

And it would work with Iris shaders just fine

[woven frost]

would be limited to what opengl can do as far as stippling i think

[heady plaza]

Yeah definitely

[woven frost]

but might work

[heady plaza]

Still, very cool concept!

Looks amazing, but lack of Iris compatibility is unfortunate

[woven frost]

yeah i'm happy with it for my purposes for now at least

would be interested to see if you try that other approach

[heady plaza]

Yeah I'll try that other approach

That'd definitely make it look a lot better

But it might hurt performance

[woven frost]

yeah i'm curious how much performance is lost on your culling approach too though

rebuilding so many blocks per tick

[heady plaza]

Surprisingly not a lot - at the very least, with just the mod

I dont actually rebuild every tick

[woven frost]

do you run into any issues with blocks not being restored after the cone moves away? i implemented a very basic version of your approach in my mod once i sufficiently understood how it worked, and i had those issues since my tracking of the culled blocks was poor

[heady plaza]

Yes, im working on some sort of permanent fix for this

[woven frost]

gotcha

i figured out what the flood fill algorithm does too. it's a cool way to detect rooms and open up the whole roof.

i initially assumed it was for detecting what blocks the player can see

[heady plaza]

Yeah it was hard to get it conceptually correct
