Fastman92LimitAdjuster (short: FLA) modifies some addresses in Grand Theft Auto (GTA) games causing compatibility problems with mods.
This class detects if FLA is installed and initializes fields that hold
memory addresses and indices that are modified by FLA according to the description in
"source code\fastman92 limit adjuster\fastman92 limit adjuster\howToMakePluginsCompatible.txt"

If FLA is not installed, then the memory addresses are set to default values (GTA Hoodlum 1.0 I beliefe).
Hence, using this class mods can be built that work with FLA and without FLA!

This version of the detector is aware of FLAs up to version 4.3. The function detect() checks if the
file "$fastman92limitAdjuster.asi" is in the current folder and reads its filesize to detect
the FLA version and then sets the addresses in the class.
You can use the global extern variable FLADetectorSAInstance (defined below) in your program.
Hence the usage is:
FLADetectorSAInstance.detect(); //Now fields are initilized and can be used
FLADetectorSAInstance.createLogfile(); //If you want to see the result of detect().

How to make plugin compatible with ID limit adjuster?

0x40122D - holds a pointer to CStreaming::ms_modelInfoPtrs array (0x0xA9B0C8 by default)
(0x408ADA + 3) - holds a pointer to CStreaming::ms_aInfoForModel array (0x8E4CC0 by default)

(0x4C51CD + 1) - holds a pointer to CAnimManager::ms_aAnimBlocks(0xB5D4A0 by default)
(0x1560EA1 + 1) - holds a pointer to CVehicleRecording::StreamingArray (0x97D880 by default)
(0x408AB9 + 1) - holds a pointer to CTheScripts::StreamedScripts (0xA47B60 by default)

Structure CStreamedScripts is modified.

Fields:
CStreamedScriptInfo[numberOfSCMscripts];
int largestExternalSize;
__int16 countOfScripts;
__int16 field_A46;


See this structure:
#pragma pack(push, 1)
struct CStreamedScripts_Footer
{
int largestExternalSize;
__int16 countOfScripts;
__int16 field_A46;
};
#pragma pack(pop)


If you want to access the last 3 members, you need to calculate address like this:

CStreamedScriptInfo* CTheScripts__StreamedScriptsArray = (CStreamedScriptInfo*)CTheScripts__StreamedScripts;
CStreamedScripts_Footer* CTheScripts__StreamedScriptsFooter = (CStreamedScripts_Footer*)(CTheScripts__StreamedScripts + numberOfSCMfiles * sizeof(CStreamedScriptInfo));

------------------------------------

Base ID indexes (DWORD values)
(0x407104 + 2) - holds TXD base index (20000 by default)
(0x410344 + 2) - holds COL base index (25000 by default)
(0x4044F4 + 2) - holds IPL base index (25255 by default)
(0x44E4C4 + 1) - holds DAT base index (25511 by default)
(0x40C1A4 + 1) - holds IFP base index (25575 by default)
(0x4594A1 + 2) - holds RRR base index (25755 by default)
(0x40C1C4 + 1) - holds SCM base index (26230 by default)

If you need to know the value of ID limits, you should perform subtraction.
numberOfTXDfiles = baseCOLindex - baseTXDindex;

To know the limit of SCM scripts, you should read WORD value from 0x470917

Simply add this source code to your mod and use the provided memory addresses.

[fastman92]

This is completely unnecessary, anyone skilled enough who writes ASI plugins knows better way to make the plugins with/without the FLA.

[PlatinumSerb]

Good work goodidea! Im sure many people will find this useful.

 

@Fastman: if you have better alternatives please share them. It will only help the community.

It would probably be better to check if fla ASI is loaded instead of mining for the file yourself.

[fastman92]

Good work goodidea! Im sure many people will find this useful.

 

@Fastman: if you have better alternatives please share them. It will only help the community.

Read the address directly in the project.

 

The FLA exports some functions, which can be used 32-bit file IDs, 32-bit difficult file IDs and other functions.

See ForOtherProjects directory in RAR.

 

At this point it could to be mentioned that the SilentPatch was the first plugin to implement the 32-bit DFF/TXD IDs. Well done, Silent!
