I thought it was more relevant here since I get the feeling most people there don't play GMod anymore but thanks, I'll post there now :)!

I know I've posted a lot of pictures of this so far, but I thought this one deserved it. The sad thing is that when I get the actual generation done I can't imagine it making something this magnificent.

Appearantly FractionLeftSolid is broken as shit, I had to do some ghetto thickness measuring with util.PointContents, it works decently though
It doesnt work on models though (fractionleftsolid did neither), I need to figure out a decent method to measure the thickness of models across a line

That system of yours is just freaking amazing :D
Would be awesome if you would allow me to implement it in my RPG when you're done.

These LUA tables are making me insane..

I wrote a little utility function to make a table indexed from 0 for me, but it uses varargs and other terrible hacks.

[lua]
function array( ... )
local content = { ... }
local array = {}

for index, val in ipairs( content ) do
array[index -1] = val
end

return array
end
[/lua]

What do you think, shall I get used to that indexing is from 1 ([IMG]http://www.facepunch.com/fp/ratings/tick.png[/IMG]), or I should stick to hacks like this ([IMG]http://www.facepunch.com/fp/ratings/cross.png[/IMG]) ?

Sorry for spamming waywo with my questions, but I wanted to ask more experienced developers :smile:

[Lily]

Instead of that content local you can just do ipairs{...}

Just get used to indexes starting at 1. I mean seriously it's one index position and if you include this code to shift the table so it works for you it's going to confuse everyone else.

ehhh

    sometable[0] = table.remove( sometable, 1 )

More metal.
Sexy hexagons.
Better tooltips.
A templating system.

The main tooltip template looks like this:

[img]http://puu.sh/10kEg[/img]

Every item type can declare it's own tooltip templates.

Numbers are spacers.
Strings are templates (will be replaced when processing).
Tables are actual data. They are processed when the tooltip is shown.

The tooltips are turning out to be harder than the inventory itself.
And I've barely scratched the surface of what I plan to do with them.

Whm, you got a point there. Also thanks for the feedback.

I rewrote the maze generator code, and also made a mesh generator for it:

[IMG]https://dl.dropbox.com/u/7659139/Facepunch/gm_maze_wip2.jpg[/IMG]

I am getting some visual issues tought, like the ligting is not perfect, and also a lot of "Z fight" on the corners.

It is now a big mesh without connected verticles, so there could be 2 overlapping walls on the corners, so there is work left, but so far so good.

Altought, I am pretty afraid to initialize a pysics mesh from that mess ([sp]wonder why[/sp] :v:), but it would be required, as I would like to use it as a map for a gamemode.

How do you actually generate mazes? I tried to make one like a year ago, but it didn't work that well out..
Are you planning to release the maze generator code? I'd love to take a look at it.

There was a toybox entity that generated mazes.

Sure! It is not a big project, or something I want to sell.
Luckily I just finished separating the generator code from the other mess, so here you go: h[URL="https://gist.github.com/3535839"]ttps://gist.github.com/3535839[/URL]

It contains a few glua only operators, but it can be fixed by a simple search and replace. ( As you see, the gist hilights them with red )

I would be happy to see if someone used it actually for something bigger.

[editline]30th August 2012[/editline]

Added the print method I used to debug to the gist too

Would anyone use a system which converts the whole of GLua to a class-like system? Something like this:

module "MyAddon"

using System
using System.Addon

namespace MyAddon

class Addon (BaseAddon)
function Addon:OnActivate()
  print( "My addon was activated!" )
end
function Addon:OnDeactivate()

end

There would be a tonne of useful classes to use in the standard library and would wrap GLua things, you could do things like have a server run multiple gamemodes at once or switch between gamemodes at will just by having a bunch of gamemodes inherit off the BaseGamemode class and stuff like that.

That's actually a great idea, considering that's all perfectly valid syntax too. Neat!

Yes please! I can't really code without OO so I'd love a proper OOP framework :)

[ペゴボド]

I cannot wait, 2 days until a new thread.

[thomasfn]

local function TestFile()

	gear_module "MyAddon"

	using( System )

	namespace( Test )

	class "Hello"
	function Hello:Hello()
		print( "Hello world" )
	end
	function Hello:TestFunction( param )
		print( "param = " .. tostring( param ) )
	end

	class "Hello2" inherit "Hello"
	function Hello2:Hello2()
		print( "Hello world again" )
	end
	function Hello2:TestFunction( param )
		self:CallBase("TestFunction", param)
		print( "inheritance ftw" )
	end


end
TestFile()

local function SomethingElse()

	using( Test )

	local o = new( Test.Hello2 )
	o:TestFunction( 10 )
	print( o:ToString() )

end
SomethingElse()

Output:

Hello world
Hello world again
param = 10
inheritance ftw
Test.Hello2 (table: 00638DC0)

I used functions to simulate code being run in separate files. Unfortunately Lua only accepts bracketless function calls if the 1st (and only) parameter is a literal, so we can't have things like "using System" without brackets. The using and namespace functions are quite happy just accepting strings though, so you could do the following instead if you wanted. Also that using system isn't actually needed in the first function as I don't use anything from that namespace. I thought I'd call the system "gear" because it sounds cool and is somewhat relevant, unfortunately I couldn't come up with an acronym for it.

using "System"

namespace "Test"

Tomorrow I'll work on the standard library and wrapping GLua functionality up into classes.

Physics from mesh, harder than I tought. I generated a mesh, and I can draw it perfectly with IMesh:Draw(), but...

First I found 3 functions to init physics from a mesh

Entity:PhysicsFromMesh
Entity:PhysicsInitConvex
Entity:PhysicsInitMultiConvex

Of course, all undocumented. :v:

At the first attempts, nothing happened, not even an error or something, just my entity was missing physics.

When I tried the Entity:PhysicsFromMesh, gmod13 actually crashed, and before completely stopping, it tried to connect en external IP adress. :tinfoil:
