Hi all, I Know how to adjust the spread value of Player Actor weapons using weapon.dat pointers with this links:
http://ugbase.eu/index.php?threads/bullet-gravity-and-velocity.21608/#post-126605
http://gtamodding.ru/wiki/Адреса_Памяти_(SA)
http://hotmist.ddo.jp/struct.html

But I was wondering how to make bullet armed vehicles like Rustler and Hunter to not spread its bullets when firing. This flying vehicles autoaims on targets, but like normal guns, the bullet does spread on its autoaimed target which sucks. That's why I want to make its bullets not spread.

I have researched about this bullet types:
  • Rustler Bullet = M4 Bullet
  • Hunter Bullet = Minigun Bullet
I tried to change the value of accuracy pointers into 1000.0(nospread):
  • M4
    • C8B880 = 0x70(31 + 0) + 0xC8AAB8 + 0x38 <---------- for std
    • C8C370 = 0x70(31 + 25) + 0xC8AAB8 + 0x38 <---------- for poor
    • C8C840 = 0x70(31 + 36) + 0xC8AAB8 + 0x38 <---------- for pro
  • Minigun
    • C8BB90 = 0x70(38 + 0) + 0xC8AAB8 + 0x38 <---------- for std
    • C8C680 = 0x70(38 + 25) + 0xC8AAB8 + 0x38 <---------- for poor
    • C8CB50 = 0x70(38 + 36) + 0xC8AAB8 + 0x38 <---------- for pro
But it only changes the Actor carried M4 and Minigun weapon, rustler and hunter bullet still spreads.

Does anybody know how to make both rustler and hunter bullet to not spread? It will be really helpful even if it is just a memory address/demonstration/working script. Thank you!

I use these two test servers:
37.252.189.76:7778
samp.ugbase.eu:7777

Even on these servers, the rustler and hunter bullets still spreads. If you would like to take a look on what I have done so far:

The Goal of the above code is to make the bullet of all Actor Weapons and Vehicle Weapons not spread when fired continuously. But the current result of this script has a problem on both rustler and hunter bullets, it spreads. I think I am missing some address for vehicle bullets. I can't find any documentary in the internet regarding "vehicle weapon stats".

I Think You Can't Change It. Because Vehicle Weapons Sync In Game. After Change Too Will Be Only Sync For You

I think both actor and vehicle bullet works the same thing, as a certain bullet was fired, a bullet data sync was made. If you have a NoSpread MOD, that MOD just changes the weapon.dat accuracy of actor weapons, but has no problems when it comes to syncing aim data and bullet data. So changing the spread/accuracy value of vehicle weapons will do the same trick as that.

I just don't know what are the memory address to change the rustler/hunter firing accuracy.

How you get weapon on vehicle?
I never used something like that.

I tried inspecting RAKNET Outcoming Packet + RPC, it seems that SAMPFUNCS cannot intercept the bullet of rustler and hunter. Everytime I fire a bullet, there is no "PACKET_BULLET_SYNC" or even "RPC_GIVETAKEDAMAGE" Data detected to be delivered.

You Are Not Sending Bullet Data When Shooting In Vehicle. Its About Key Sync You Can Try It Like That When Someone Shooting Hunter Disable Incoming Vehicle Sync From Her Except Key Data He Will Keep Shotting Last Position To Same Direction On Your Screen

Can you give me the struct of key data sync?

I don't quite understand how the bullet will hit/damage the targets using key data sync. If it is just shooting but the bullet still spreads around the target, then the idea does not fix the bullet spread logic for vehicles.

Code: 
struct VehicleSyncData

uint16_t keysData;
..
..
}

If You Set Keys Data In Incoming Vehicle Data keysData |= (0 << 4) When Other Players Shooting In Vehicle Its Not Will Sync For You When You Just Disable Key Data LMB/CTRL

Ok, I get your Point. Keysdata is what makes your vehicle shoot on other player's screen. But I still want to try to make rustler/hunter bullet to not spread, I want to test what will happen if rustler bullets have 100% accuracy and hits targets without miss when autolocked...

You Need Find Memory Adress But After You Change Memory For No Spread Its Sync Only Your Side When You Or Any Player Shooting In Hunter/Rustler Your Bullets Will Spread On Others Screen

Yes I kept that in mind, that is why I am asking for help to find the memory address from the beginning. I am having a hard time finding it, maybe you or somebody can help me point out the proper memory addresses.

You can get current weapon id , but i can't see anything about spread.

After conducting experiments. It seems that the following damage/bullet parameters are done in the client side and was not received from the server:
  • Explosions - if an explosion within your near proximity happened, an explosion "RPC Take Damage" was sent to server)
  • Helicopter Blades(when a person hits the your helicopter blades, the client sends an "player instant death by you" towards the server)
  • Actor on Fire - when your player was burned, a Fire "RPC Take Damage" was sent to server. Meaning when you used a flame thrower to an enemy, the enemy's own client itself deals damage to himself.
  • Player Rammed by a Vehicle - if you are hit by a vehicle or is laying down under a car, your client sends a melee "RPC Take Damage" to the server. So you are just damaging your self behind the scenes.
  • Player Fall Collision - when your player is falling, your client sends multiple "PACKET_PLAYER_SYNC" and the server reads "sCurrentAnimationID" and "sAnimFlags" to detect if you are falling, the damage after the collision towards the ground will be based on "fMoveSpeed[3]" so the faster you are falling the more damage you will received after the fall.
  • Vehicle Bullets - you fire a bullet/missile weapon on a vehicle, all players streaming near you will receive your
    1. "PACKET_VEHICLE_SYNC" that have the info if you are firing a weapon by detecting the keys you currently pressed.
    2. "PACKET_AIM_SYNC" the direction of vehicle bullet will be read here.


All those Damage types are client sided and no "RPC GIVE DAMAGE" are received from the server. It also seems that this Damage can be evaded by:
  • Blocking "RPC TAKE DAMAGE"
  • Blocking Incoming "PACKET_BULLET_SYNC" where our player or car is hit by the bullet

You can get current weapon id , but i can't see anything about spread.

It only sends what weapon does the actor currently holding while driving.

So yeah, changing the spread value will be useless since the damage of the vehicle bullets is conducted on the other player's client. So I will not try to dig up its memory address anymore. Thanks everyone.

After conducting experiments. It seems that the following damage/bullet parameters are done in the client side and was not received from the server:
  • Explosions - if an explosion within your near proximity happened, an explosion "RPC Take Damage" was sent to server)
  • Helicopter Blades(when a person hits the your helicopter blades, the client sends an "player instant death by you" towards the server)
  • Actor on Fire - when your player was burned, a Fire "RPC Take Damage" was sent to server. Meaning when you used a flame thrower to an enemy, the enemy's own client itself deals damage to himself.
  • Player Rammed by a Vehicle - if you are hit by a vehicle or is laying down under a car, your client sends a melee "RPC Take Damage" to the server. So you are just damaging your self behind the scenes.
  • Player Fall Collision - when your player is falling, your client sends multiple "PACKET_PLAYER_SYNC" and the server reads "sCurrentAnimationID" and "sAnimFlags" to detect if you are falling, the damage after the collision towards the ground will be based on "fMoveSpeed[3]" so the faster you are falling the more damage you will received after the fall.
  • Vehicle Bullets - you fire a bullet/missile weapon on a vehicle, all players streaming near you will receive your
    1. "PACKET_VEHICLE_SYNC" that have the info if you are firing a weapon by detecting the keys you currently pressed.
    2. "PACKET_AIM_SYNC" the direction of vehicle bullet will be read here.


All those Damage types are client sided and no "RPC GIVE DAMAGE" are received from the server. It also seems that this Damage can be evaded by:
  • Blocking "RPC TAKE DAMAGE"
  • Blocking Incoming "PACKET_BULLET_SYNC" where our player or car is hit by the bullet
