I've been hacking around with RuneScape OldSchool for the past few days, using Scala. First I wrote my own loader to host the game applet (not that much code), which only took a few hours. Then I started reverse engineering the game client in order to implement features such as XP and loot statistics in the future. The code uses many different ways of obfuscation, such as randomized (and sometimes conflicting) field names, dummy parameters and values such as HP and levels being multiplied by a constant. However, I made a breakthrough by using heap dumps and analyzing them in VisualVM, which makes reverse engineering class fields a bit easier. Currently my client's API can read chat messages, get nearby players and NPCs, and get/set data in the login screen. I also managed to do this:

There's a ton to do, and it's a very tiring environment to program in. I also need to figure out a way to automate deobfuscation, if possible, since my code will break on every engine update. I'd also love to open source this, but I'm not sure if Jagex would approve, as you could easily reuse most of the code for a bot framework.

I've been hacking around CSGO. Made this video:

[video=youtube;GoAq6eQXEt4]https://www.youtube.com/watch?v=GoAq6eQXEt4[/video]

btw the video is really low FPS because I didnt render it.

I pretty much hooked an SDK function called OverrideView doing this:

void __fastcall hkOverrideView(IClientMode* clientMode, DWORD edx, CViewSetup* viewSetup)
{
	viewSetup->fov += 50;
}

Then did this

	pClientModeHook = new CVMTHookManager((PDWORD*)g_pClientMode);
	pClientModeHook->dwHookMethod((DWORD)hkOverrideView, 18);

I also made a HUD (healthbar)

[IMG]http://i.imgur.com/rO1E3oN.png[/IMG]

and I did that by doing this. Once again just hooking PaintTraverse (another CSGO sdk function)

typedef void(__thiscall *tPaintTraverse)(void* ecx, unsigned int, bool, bool); 

then

CVMTHookManager* pPanelHook = new CVMTHookManager((PDWORD*)g_pVGuiPanel);
	tPaintTraverse oPaintTraverse = (tPaintTraverse)pPanelHook->dwHookMethod((DWORD)hkPaintTraverse, 41); 

then

void __fastcall hkPaintTraverse(void* ecx, void* edx, unsigned int vguiPanel, bool forceRepaint, bool allowForce)
{
	oPaintTraverse(ecx, vguiPanel, forceRepaint, allowForce);

	if (!strstr(g_pVGuiPanel->GetName(vguiPanel), "MatSystemTopPanel"))
		return;

	CBaseEntity* cLocalPlayer = (CBaseEntity*)entitylist->GetClientEntity(engine->GetLocalPlayer());

	g_pVGuiSurface->DrawSetColor(Color(255, 0, 255, 255));
	g_pVGuiSurface->DrawFilledRect(29, 29, cLocalPlayer->health(), 46);
}

and then

	pPanelHook = new CVMTHookManager((PDWORD*)g_pVGuiPanel);
	oPaintTraverse = (tPaintTraverse)pPanelHook->dwHookMethod((DWORD)hkPaintTraverse, 41);

THANK YOU FOR THE PROGRAMMING KING RATING GUYS :D ITS THE FIRST TIME I EVER GOT THAT ;D

Some more OoeyGUI work. Implemented ProgressBar, DoubleProgressBar, and improved the final buffer copy into the Console and the way rect invalidation works:

lbl.Text = new FormattedString(begin, perc, mid, perc2, mid2, step, end);

Cool shit man. Looks really pretty :D

[WTF Nuke]

I've been trying to convert my ECS from using Boost MPL (which is C++03) to using Boost Hana (which is C++14) and basically my approach so far has just been drop in replacing what I have.

To keep a list of all the entities with a tag, I created an array of sets, and each set used to hold Entity IDs. So basically, it would look something like this when fully evaluated: array<set<EntityID>, tagNum>. I would access the correct set by keeping the list of types in a tuple, and you could find the correct element by using get<type>. As you can see, there is a clear separation of the array that holds the data, an what each element in the array represents.

Now I was trying to replace the MPL set that created the tuple. You see, to get the actual tuple of types I converted a variadic type list into an MPL set, then converted that into a tuple. Lot's of work needing to be done (and since MPL is C++03, the manipulation of variadics is archaic and bloats compile time). Basically, I got as far as replacing the MPL set with a Hana set, but I couldn't find a way to convert finding a type in the set to getting an index. I mean, how else am I supposed to access my array? I was frantically looking at the documentation, and I just couldn't make sense of how to do it.

But then it struck me. Holy shit, Hana doesn't just work with types. I can just have a Hana map that maps a type to a set of Entity IDs. It just makes so much sense. Now I don't have 4 or 5 different steps littered with different types to get my end result. No, I just need to use a single freaking Hana map, which goes type -> set<EntityID>. C++14 boost libraries are basically magic.

Why are you storing lists of entities that contain a tag in the first place?

Also, tuples sound completely fine for what you're doing.

First of all, we need to create a type that lets us differentiate between them based on their type parameter. Since std::set<EntityID> contains no type information (besides EntityID, but they all have that) we need to wrap it in some other structure that can let the tuple know
what kind of EntityIDs are stored in it:
[cpp]
// We need a wrapper to be able to do type lookup
// Otherwise our tuple will just be tuple<set,set,set>
template<typename tag>
struct typed_set : public std::set<EntityID> {};
[/cpp]

Now, we need some way of expanding a list of tags into a tuple<typed_set<Tags>...> structure:
[cpp]
// Expand tags into a tuple<tset<T1>, tset<T2>, tset<TN>, ...> type
template<typename ...Tags>
using tag_lookup_storage_impl = std::tuple<typed_set<Tags>...>;
[/cpp]

To define the final type with all the tags, we simply use the impl:
[cpp]
// Define a storage type that can hold all our sets
using tag_lookup_storage = tag_lookup_storage_impl<
tags::player,
tags::boss
>;
[/cpp]

Now all we have to do is instantiate an instance of the tag_lookup_storage and define a way to access it by type:
[cpp]
tag_lookup_storage tag_lookups;
template<typename Tag>
std::set<EntityID> &get_by_tag()
{
return std::get<typed_set<Tag>>(tag_lookups);
}
[/cpp]

This isn't an attack on Hana or anything, I just wanted to show how reasonably easy it is to do with the tools already available to you, without needing libraries like Hana.
Also you should check out SupahVee's presentation on his template-heavy ECS system:
[media]https://www.youtube.com/watch?v=NTWSeQtHZ9M[/media]

He does a lot of really neat things with it, like signature matching for component/entity systems at runtime, instead of having separate sets for each tag, meaning that tags are (almost) completely overhead-free, except for when you're looking for them.

[QUOTE=Darwin226;50401197]So where does LLVM lie between the CIL and assembly? How hard is it to target it with a custom compiler?[/QUOTE]

From what I remember when I wrote a compiler with it a few years ago, it's quite a bit lower level. For example, there's no object oriented stuff built in, so I had to implement vtables / inheritance myself. I'd say it's closer to assembly than CIL. It was relatively easy to target though, the language documentation is pretty clear.

I've never written a compiler personally but having to manually handle the function stack sounds pretty intimidating. Do you have to do that in LLVM (this might not even be necessary in assembly; I've only ever wrote some archaic flavor of it)?

Nah, that's one thing LLVM does for you. It's like mid-way between C and assembly. You still have to break down expressions into individual operations, and control flow uses labels and branches, but you can define and call functions with LLVM's syntax.

once again just hooked paint traverse and drew on it.

then looped through players
then draw bones
