What are you working on? January 2012

[QUOTE=amcfaggot;34204185]I don't use mercurial, but doesn't it have revert? This doesn't seem like a good reason to prefer X over Y to me.[/QUOTE]

Mercurial's... "thing" is that it tries to keep history intact, always. There are of course ways to undo commits and edit history, but they're generally not recommended.

[editline]14th January 2012[/editline]

I've kept a couple days' break from iris, since I've been sick and had to deal with university stuff.

I've created basic entity wrappers and bindings. I'm wrapping Source entities in my own classes, since the headers are outdated and trying to rebuild them from vtables is horrible due to multiple inheritance (different compilers handle it differently. I generally use mac binaries for vtables, since they contain some debug info)
I'm not using recvprops yet, so I'll write about them later. Right now my wrappers can only list entities and identify player entities. I've hooked OnEntityCreated and OnEntityDeleted from a Source interface, which I use for building a list of entities. I could use Source's own entity lists, but that would require more work every time you query the list, whereas Luabind supports binding STL iterators as tables, so I can just return the internal list.

So that my post isn't all text, have this:

[lua]local clr2 = Color(0, 128, 255, 255)
hook.add( "Paint", "test", function( str )
if not INGAME then return end

local c
surface:SetColor( clr2 )
for ent in entity.GetAll() do
if ent:IsPlayer() then
c = ent:GetAbsOrigin():ToScreen();
if not c.behind then
surface:DrawOutlinedCircle( c.x - 5, c.y - 5, 5, 18 )
end
end
end
end )[/lua]

[QUOTE=Chandler;34204115]Look into git filter-branch. Actual ways in which to fix this are [url=http://stackoverflow.com/questions/750172/how-do-i-change-the-author-of-a-commit-in-git]here[/url][/QUOTE]

Thanks, but I'd have to set up Git to do this. It's only two commits and the author should is set, so it's not that bad.

Hg has something similar, but it's impossible to push a remove branch to a remote repository. (I only noticed it after pushing to GitHub.)

[editline]14th January 2012[/editline]

I'll test if it works now in a test repository before making more commits...

It works. Hg usernames are usually "User <Email>", wich is translated correctly by hg-git.

haskell dude!

[editline]14th January 2012[/editline]

The equivalent in Kari would be:

(a -> (b -> (n -> if eq n 0 (a) (fib_ b + a b - n 1)))) => fib_

(n -> if lt n 2 (1) (fib_ 1 1 n)) => fib

Don't blame me! All the functional languages look alike.
So you're learning haskell?
I thought making a haskell interpreter would be more along your skill set.

the funny thing is, kari itself has no idea what that code means until runtime!

[r0b0tsquid]

You can assign into arrays now :) (indexed assignments)

Just have to get that working for multiple assignments, and then fix parametrics (which I broke by changing the assignment representation/logic)

I'm pretty sure it doesn't know what it means at runtime either? Unless that's some deeper comment about how the language is parsed/executed.

Also, I have to consciously avoid referring to your language as "she" :v:

I think he means the whole currying thing. Functions building functions that build other functions, etc.

Wrote a brainfuck interpreter in graphscript:

It supports nested loops too!
I guess that this proves my grapher's Turing complete? :v:

The red line is a visualization of the memory buffer: it's just a plot of the relation "y = mem[x]" :)

[Tezzanator92]

Now write a grapher (with graphscript) in graphscript that can load a grapher (with graphscript) written in graphscript...

A certain early 80s sci-fi film springs to mind.

Let it access the system information and plot the graph of current CPU usage.

So, RecvProps. They're one of Source's networking methods for entities. Entities can declare a [url=https://developer.valvesoftware.com/wiki/Networking_Entities#Network_Data_Tables]data table[/url], which is shared between the server and client. It's used to serialize and unserialize the entity's data for networking. Since it's declared on client, there's naturally a way to access the tables, and it's IBaseClientDLL::GetAllClasses, which returns the first element of a linked list of data tables, also called ClientClass. Each class contains the entity's tables, which in turn can contain properties and more tables. [url=http://pastebin.com/RgTCSrBE]Example dump[/url] from TF2.

Now, why are these data tables important? Because they contain offsets to the members they declare. So, if you have a C_BaseEntity and you want to get its origin, you'll either have to rely on outdated headers or use offsets. We can parse the data tables during runtime and get the offsets, then use the data strings to get the offset when we need the member data.

I use them like this:
[cpp]int
source::player::health() const
{
return offset_map.get<int>(entity_, "DT_BasePlayer->m_iHealth");
}[/cpp]

offset_map.get just gets the offset of the given data string and adds it to the pointer, then casts it.

Since we now have a method (besides outdated headers) to get entity data, we can expand the entity and player wrappers. And so, I have this.

Sure! I haven't actually shared this with anyone so don't mind any ugliness. However I generally make it a rule for myself to comment everything, so you hopefully shouldn't have a problem figuring the stuff out. [URL="http://dl.dropbox.com/u/10657252/Libtcodtesting.rar"]Here's the download[/URL].

I use CodeBlocks and I didn't feel like removing all the irrelevant files, so just ignore them if you don't need them. If you don't feel like compiling the code, just go to bin/debug and the executable there should be ready to go.

Wrote up some primitive input methods and a login 'random'. If you're unfamiliar with rs bot terminology, there are these locations known as randoms which the player would be abducted to at random times and made to complete a challenge which was purposely made difficult for a bot. These 'random' scripts had a method which was called periodically (every few seconds) in an attempt to detect this random. A login script was usually also made a random due to its similar nature, somewhat.
