[CLEO] Cop Bikers Overhaul

[center][large]Cop Bikers Overhaul 1.0[/large][/center]

Overhaul? Huh?

By default, GTA SA has unique cop model for each city. However, there's only one cop biker for whole state. It has a bit of nonsense, as his model name apparently tells that is a LS biker. Also, Rockstar left in gta3.img two fully usable models of bikers for SF and LV.

Why not make them usable? This mod (or rather, this plugin) adds them to the city, as they should be placed, according to their names.

Believe me or not, that mod doesn't spawn cops by itself, only hacks the EXE routines. However, you even don't have to believe me, as mod is open sourced smile

This mod is compatible with the CLEO 3/4 Libraries found here:
http://cleo.sannybuilder.com/

Put cbo.cs in GTA San Andreas\CLEO directory and peds.ide in GTA San Andreas\data directory to install the mod.
If your peds.ide file is modified, add mod lines by yourself by pasting them below #---ADD NEW PEDS HERE line. You have to paste these two lines:

272, sfpdm1, sfpdm1, COP, STAT_COP, swat, 1FFF, 0, null, 9,9, PED_TYPE_EMG,VOICE_EMG_MCOP1 ,VOICE_EMG_MCOP6
273, lvpdm1, lvpdm1, COP, STAT_COP, swat, 1FFF, 0, null, 9,9, PED_TYPE_EMG,VOICE_EMG_MCOP1 ,VOICE_EMG_MCOP6

You don't have to worry about cop models, as they are in all SA copies in gta3.img archive, just unused.

Screenshots:

Two SF bikers.

Annoyed LV biker chases poor taxi driver (running on GTA: The '95 Story mod).

Or here

Known bugs:

As mod modifies several hardcoded routines, it might crash on some EXE versions (1.0 US HOODLUM and Compact are tested and bug free). Contact me if you have any problems with it.

Too lazy to download whole package just to see the source?

Here it is, then.

Cool, but mod that you've linked controls it via CLEO script. Mine injects some ASM codes and just shuts down.
