20 projected textures with no shadows should be ok I suppose.
[QUOTE=garry;38194512]Optimised the internals of the userdata system[/QUOTE]
Can you explain this? I'm curious.
I've experimented a lot with userdata implementations and ended up using light userdata as a key and a table instead of full userdata.
pseduo code:
[lua]
function Push(pointer, meta)
REGISTRY[pointer] = REGISTRY[pointer] or setmetatable({__ptr = pointer}, meta)
end
function Get(pos)
local obj = STACK[pos]
return cast(obj.__ptr)
end
[/lua]
This means when you push entities to lua it won't create any new userdata if it has already been pushed once. It will just reuse.
When I'm done with the entity I just remove the table from the registry and set its metatable to a NULL one.

Yeah the entity system already does that.
The issue I had was that when I was pushing userdata I was allocating and pushing a pointer.. so when it came to look up the type I was pushing the meta table and getting the typeid which was stored on it.
So instead of doing that stupid shit I store a generic struct as the userdata, which has the typeid and a data pointer.
This is a bit of a speed up because pretty much every call to an entity, or vector, or whatever, looks at the type.. so instead of pushing a table, looking up a member blah blah blah. It just converts the userdata and looks at the type id.
[QUOTE=twoski;38195424]flashlight[/QUOTE]
How'd you get it to maintain the player's angles? I tried using a projectedtexture in my gamemode but when I set the player to be the parent not only is it laggy, but it just faces Angle(0, 0, 0) for everyone not in first person.
ie. if I'm looking at another player's flashlight, it faces 0 0 0. If I'm looking at my own flashlight from 3rd person, it faces 0 0 0. If I'm looking at my own flashlight from 1st person, it's correct, if laggy.
A clientside alternative would be the shit.
[lua]

local c = Color( 255, 255, 200 )
local b = 4 // brightness
local size = 50
if self:GetLoadout( 3 ) == UTIL_LIGHT then
b = 6
size = 55
end
self.FlashlightEnt = ents.Create( "env_projectedtexture" )
self.FlashlightEnt:SetParent( self )
self.FlashlightEnt:SetLocalPos( Vector(0,0,64) )
self.FlashlightEnt:SetLocalAngles( Angle(0,0,0) )
self.FlashlightEnt:SetKeyValue( "enableshadows", 0 )

Pros:
- All done in Lua, using an env_projectedtexture.
- Customizable color, length, radius, flashlight texture, shadow settings.
Cons:
- It's all fucking serverside because ents.Create doesn't exist on the client anymore.
- IT'S ALL FUCKING SERVERSIDE. I dunno what the performance hit of 20 projected textures all being used at once would be but i'd hazard a guess that it will shit all over your FPS.
If possible it would be nice to be able to create these on the client. Why did ents.Create get removed from clientside anyhow?[/QUOTE]
Maybe instead of an fps expensive flashlight, just make the flashlight twitch and burn out when you get within a certain distance from the invisible dude. That would make things way more scary.
Or even when they flash the light on the invisible dude, then you could have it burn out so they get to see him for a second then he is gone and that player loses his light.

How about you're using the players [I]EyeAngles()[/I] to determine the correct angle for the env_projectedtexture-entity?

Currently your flashlight runs on battery power, so you can't keep it on forever. The problem is, with 20+ players there will be times where every player has their flashlight on. In this case, it would be smarter to just have clientside flashlights.
But i am at the mercy of what garry decides to do with gmod lua so if he decides to allow certain ents to be spawnable clientside then i'm making this code clientside.

env_projectiletexture is that expensive?
twoski, you can create a clientsidemodel instead
run something on the client to move each player's flashlight clientsidemodel entity infront of their respected players, and use this entity as a basis for the flashlight

how exactly would a clientside prop emit light? they are basically the same as a prop_physics but without a physics mesh. I am asking for the ability to create entities other than physics props on the client.

Projected Texture, you mean. But yes, they seem to be... my framerate started dipping when i was messing around with several of them in sandbox (the lamp entity in sandbox uses them).

So since GLON was removed, and I don't like JSON, I created my own 'database system' that saves shit to .txt files, reads info from the files and organizes them into ready tables to use.
This is a major breakthrough for me, because I did this with no proper knowledge on how databases are coded and/or work. It's also slow as shit, but I don't give a fuck. :v:

100000 times.
I did some benchmarks and apparently it takes 7 seconds to read the file 100000 times and 28 seconds to organize the table.
JSON's output is 562 symbols and mine is 173 symbols, but it only takes JSON 10 seconds to decode all that.
Edit: Welp, this was an interesting test, and I'll stick to JSON, because I realized that I can do the same with JSON, but much faster.

Not much of a json fan in lua. Sure it's useful to have when dealing with the internet but for internal uses it it feels like if you were to use a lua compilable data in javascript. Why not make "lson"?
There are many implementations of it out there and it's relatively easy to make.
The fact that JSON is already implemented in a lot of other languages and is still human-readable is the biggest advantage for me.

That's true. I'm talking more about data that doesn't leave glua. BUt when you do want it to leave lua it's dead easy to do (tojson(loadstring(data)()))
I'd rather use "lson" or json rather than keyvalues or anything else though.
