HPB_bot2_i486.so, HPBot2 ver 0.5 release 106 Options

[bir3yk]

I compiled a linux RCBot2 0.5

1. Folder Structure :
.../hl2
.../orangebox <-- srcds_run is here (for TF2 and Orange-Box games)
.../orangebox/bin <-- HPB_bot2_i486.so files copied here
.../rcbot2/
.../rcbot2/config/
.../rcbot2/profiles/
.../rcbot2/waypoints/
.../rcbot2/waypoints/orangebox/tf/ <-- waypoint and scripts files copied here
.../steam
2. Edit .../rcbot2/config/bot_mods.ini
mod = TF2
steamdir = orangebox
gamedir = tf
bot = TF2
3. Add
./srcds_run ..............+plugin_load ../bin/HPB_bot2

have a look at sourcemod to see if its the same

CODE

    void Protect(void *addr, size_t length, int prot)
    {
# if defined PLATFORM_WINDOWS
        DWORD ignore;
        VirtualProtect(addr, length, prot, &ignore);
# else
        uintptr_t startPage = AddrToPage(uintptr_t(addr));
        length += (uintptr_t(addr) - startPage);
        mprotect((void*)startPage, length, prot);
# endif
    }

    static inline uintptr_t AddrToPage(uintptr_t address)
    {
        return (address & ~(uintptr_t(sysconf(_SC_PAGE_SIZE) - 1)));
    }

    {

        VirtualProtect(addr, length, prot, &ignore);
# else
        uintptr_t startPage = AddrToPage(uintptr_t(addr));
        length += (uintptr_t(addr) - startPage);
        mprotect((void*)startPage, length, prot);
# endif
    }

    static inline uintptr_t AddrToPage(uintptr_t address)
    {
        return (address & ~(uintptr_t(sysconf(_SC_PAGE_SIZE) - 1)));
    }

I believe that does the same as what I posted. An address is page aligned if it is a multiple of the page size. Mprotect will throw an EINVAL if a none-page aligned address is given as the input. To page align the address you want to supply mprotect, you decrease the address by the address modulus page size: addr - (addr % page_size).
The snippet from SourceMod uses a bit operator trick to get the same result. For example:

CODE

address    = 6             = 0110
page_size = 4             = 0100

page_size - 1 = 3         = 0011
~(page_size - 1)         = 1100
address & ~(page_size -1) = 4     = 0100
6 - 6 % 4 = 4            = 0100

I believe the reason that they chose this (if I remember correctly from my assembler class) method is that it's an optimized way of getting this calculation because modulus requires more CPU cycles to perform. But the result of this optimization will probably be not noticeable for your case as the calculation is done at most 31 times per game.

Hey Ted. Yeah I thought so too. I've been trying to compile myself on linux so I can test it myself. I've edited the rcbot files so that it compiles under linux however running into frustrations compiling the latest sdk from http://hg.alliedmods.net/hl2sdks/hl2sdk-ob-valve/

had to put

CODE

#if defined(_LINUX) || defined(__APPLE__)
#define NO_MALLOC_OVERRIDE
#endif

in memoverride.cpp as it came up with g_pMemAlloc not defined errors

now coming up with errors in memstack.cpp

CODE

I don't really want to be editing non-rcbot files as I'm not sure about all this tier stuff

[Ted]

Actually, I found that you don't really need to include the memoverride and memstack objects for compilation. The current LINUX RCBot2 code base does not use any of the functions from those objects.

Also I found it easier to just specify the project as a plugin object rather than go through the mod project route as specified by the Makefile posted in the forum. This allows you skip building vcpm project, which is severely outdated. The only draw back is that you will have to manually update the Makeifle.plugin file.

well i've updated the source files on the svn to fix the linux compile issues, and removed dependencies on the tier1 source, (just use the lib). I've run into compile problems yet again where it says "libtier0_srv.so could not read symbols: File in wrong format " garrh, I'm compiling in 64-bit ubuntu but using lib32 libs with -m32 flag, dunno what else I need to check.
