GTA:SA Opcodes

[BBumper]

I've been away due to internet funds completely running dry so I had to resort to a free AOL trial *puke* but enough about me here is what I discovered about 2 weeks ago

 

 

070E: $AIRPLANE $TARGETACTOR 400.0

- Makes #HYDRA (or any other airplane) strife/attack player ($PLAYER_CHAR)

at a radius of 400.0 - no matter what you set the second variable to

the plane will attack the player and if you try to use it on a helicopter it doesnt really fly.

 

 

 

0724: $HELICOPTER $TARGETACTOR 150.0

- Makes Helicopter ($MISURY) strife/attack player

at radius (150.0) no matter what you set the second variable to the heli

will attack the player and it if you use code on and airplane it takes a nosedive and crashes.

 

 

0710: $AIRPLANE $ACTOR -1 300.0

Makes #HYDRA (or any other airplane) fly around/attack actor ($actor)

at a radius of 300.0

 

Edit:

If it hasnt been done already feel free to name and add the code to the sa database

spaceeinstein I noticed under the description for 0724 you said it makes the aircraft (helicopter) attack the 'actor' but when I tested it a few weels ago I only got it to go after the 'player' even when I tried to send it to attack an 'actor' I created at a distance, I'm just curious did you have different results testing that particular code?

[spaceeinstein]

Whoops. Yea, it's player char only. Thanks for finding the error. Any more errors you can find?

[op9080]

I need some help naming and describing an opcode. It's this opcode:

 

 

09B4: $X $Y $radius bit_mask boolfloat $X, $Y, $radius;int bit_mask, bool;

 

 

It's used to set the visibility status of yellow entrance markers, like this...

 

 

09B4: $BUY_ASSET_PICKUP_X(3) $BUY_ASSET_PICKUP_Y(3)  10.0  16384  1

 

 

What it does is to search in a circle of radius $radius at center ($x, $y) for map objects form a certain pool. The structs in the pool are 60 bytes long. Then, if bool == 1, it ORs the WORD at offset 48 with bit_mask, and if bool == 0, it ANDs the WORD at offset 48 with ~bit_mask. So in the example above the effect is to either turn on or off bit 14 of this WORD. The yellow entrance markers are part of this pool (they're defined in *.ipl files somewhere) and this bit makes them either appear or disappear. The example above is used to turn on an entrance marker to a safehouse when you buy the safehouse.

 

I don't know what to name this opcode. For one thing, I'm not sure which map objects are in this pool (it has space for 400 objects). I'm pretty sure it's not ALL map objects, or else I don't see why this opcode would not make the building itself appear or disappear in addition to the yellow marker. Also, because of the nature of the parameters (a bit mask) it may be used to set other flags of the object other than visibility.

[BBumper]

Whoops. Yea, it's player char only. Thanks for finding the error. Any more errors you can find?

I think I found another problem with 0633 I can't get the actor to suddenly jump/roll out of a vehicle while its traveling at high speeds the car just stops or slides to a stop then the actor gets out although I don't believe you were the one who summited the description I thought I would mention it just to see if this happens to you or anyone.

[BBumper]

009A Appears to make a vehicle solid (1) or unsolid (0) I really havent tested the code beyond 0-1 so I can't say for sure say that is what is does.

 

 

099A: $Car 0 or 1

 

 

OPCode Name Suggestion:

 

 

099A: $car solid_state 1

09E7: player $PLAYER_CHAR not_frozen (if) (can someone else confirm this?)

050F: @0 = get_max_wanted_level

0560: car @1 create_random_driver @0 (actor doesn't need to be loaded, actor can be treated just like any other actors created)

09C0: get_random_car_in_area $oX1, $oY1, $oX2, $oY2, $oZ with_actors -1 = @0

Do you have any idea what "1.0" does in that opcode?

 

 

09C0: [email protected] [email protected] [email protected] [email protected] 1.0 -1 [email protected]

 

 

Edit: Perhaps it has something to do with radius., I'll go offline in a few and give it a test if you like I can send you a PM about it later.

Edited November 8, 2005 by BBumper

[Y_Less]

Its an area, so has no radius. Based on other opcodes, it will most likely be the TYPE of actor wanted, so you can look for a car with actor type 7 in that area and store its handle in @0. -1 means random (i.e. any actor/ped type).

[email protected] [email protected] = Object 1 XY coordinate

[email protected] [email protected] = Object 2 XY coordinate

 

From what I've been able to determine 1.0 is not a z coordinate and I know -1 gets a random car nearby [email protected] is the car's handle I'm just unsure about 1.0 but I think its a radius.

 

 

09C0: [email protected] [email protected] [email protected] [email protected] 1.0 -1 [email protected]

 

[spaceeinstein]

Must live!

 

09C0's fifth parameter should be the height. The getting the area is getting the rectangle at those coordinates. 053E doesn't have this extra parameter and any things within this area would trigger this opcode at any height. I tried this using the Stinger mod. I placed a vehicle above the stinger using 09C0 and it didn't pop. If I use 053E, it'll pop. If I increased the 09C0's fifth parameter, it'll pop.

 

099A is very funky for me. The vehicle would float into the air and be not solid. If CJ enters the vehicle, CJ can't use a submachine gun. If you spin the vehicle too mmuch, the vehicle would warp and will do funky stuff. In Rockstar's code, this vehicle would be assigned to a set path, be locked into position, or be invisible.

 

Well, I got one new one:

0852: set_car @0 visible_damage 0 (0=not visible/1=visible) (like the car won't get visible damage when hitting stuff but it'll still be damaged)

[ceedj]

Ok, first, some "No Longer Used" Opcodes:

 

 

011C: actor_clear_objective0372: set_actor_wait_stateBoth crash game

 

 

And a NEW one:

 

 

0687: PLAYER_ACTORshould now be0687: clear_actor_task PLAYER_ACTOR

 

 

Basically does the same thing that 011C used to. Works with other actors too.

 

I have a few more I think, but I need to do some more testing. Enjoy!

 

EDIT: Here's a bunch...

 

05B9: actor_idle $actor  10000(time in ms)   // Used between certain action sequences05BB: actor_task_fall_down  $actor 0 (int, always 0?) 3000(time in ms) // You the the one where Woozie runs into the wall and falls down? Yep, this is it...05C9:  actor_task_idle_look $actor -1 (-1, -2, or time in ms) // Just an idle stance. You see this a lot if you know what to look for...05DE: find_closest_path_and_walk $actor //PLAYER_ACTOR works too // this is AWESOME if you set it to your player - he will walk the city! Make sure you set a ket to disable or he'll do it forever...05D9: run_to_actor_and_stop $actor $actor  5000(time in ms)  2.5(float?) // Not sure about the last param, but this runs an actor to another actor in this amount of time. If time runs out, the running actor gets tired, then stops....05DB: actor_task_run_away_look $actor $actor  1000.0(float)  5000000(time in ms) //actor runs away from actor, looking over his/her shoulder...05DC: actor_task_run_away_stop_look $actor   2336.399 -18.3093  25.4766  30.0 (x,y,z,a?)  8000(time in ms) // actor runs away from point, I think. It could be TO point, but I doubt it. When the actor stops, he/she looks over shoulder...05DD: actor_task_run_away_from_actor $actor $actor  100.0  60000 // another acotr runs from actor. It's a slightly different animation; actor stops and looks both ways at the end...07A5: actor_task_fight_actor $actor $actor 1000(time in ms) // Actor fights another actor for the time specified. 

 

 

Here's a few that I haven't tested, but have some ideas on...

 

 

05C1: unknown_action_sequence -1  230 // Not sure; used with 05C9 sometimes...05CF: $actor $car  119.3556  1069.892  13.665 // drive to point?05D2: unknown_action_sequence $actor $car  15.0  0 //actor drive this speed?05DA: $actor  1646.332 -1053.721  23.385  100.0  15000 //roaming coords?05E9: @35  152 // car opcode - used once in entire game05EC: @161 // car opcode05ED: @377 // car opcode05EE: @44 // car opcode05F1: @37 @35 // car - car opcode - used once in entire game05F2: @36 @35 // car - car opcode - used once in entire game05F5: unknown_action_sequence $actor  -781.09  497.79  1370.782  6  10000 // actor does something at these coords05F6: $PLAYER_ACTOR  1030.105  2095.714  1054.818  2098.778  30.0  0 // is player in cube check?05F8: $PLAYER_ACTOR @198 @199 @195 @196 -30.0  0 // another player in cube check, used in steal cars (zeroing in?) and boat school (check points?)05FC: $PLAYER_ACTOR $3401 $3402 $3403 $3404 $3405 $3406 $75  0 // player in 3d cube?05FD: $PLAYER_ACTOR -1611.833  1334.313  .8012 -1615.812  1329.394 -7.9862  2.0  0 //similar to above?05FE: $PLAYER_ACTOR @198 @199  1.0 @195 @196  3.0  10.0  0 // similar to above?0603: unknown_action_sequence $actor  2299.284 -1133.929  27.3281  6 -1 // actor does something at these coords0604: $73 $74 @20 // operation? 1 and 2 are floats, 3 is usually a variable (such as Z angle)0606: -1695.1  587.6 -1771.3 -1310.0  // sets of coords? used once in entire game 

 

 

EDIT:

 

Ok, this seems to be an idle_stance OR an animation cut off. But I'm guessing the idle_stance:

 

 

0792: idle_stance $actor

 

 

And this one seems to do the same thing as 0605: actor_perform_animation_sequence:

 

 

0812: actor $actor perform_animation_sequence "PRTIAL_GNGTLKC" from_file "GANGS"  4.0 loop  0  0  0  0 -1 ms 

 

 

Although I wonder why they would have two opcodes that do the same thing. But they do...

 

@ spaceeinstein : your toggle_HUD opcode in the DB is backwards. Should be 0(off)/1(on). Just so ya know.

 

Enjoy!

Nice finds there.

 

Damn, after I disappeared from here, barely anyone found anymore new opcodes?

 

 

I got two new ones:

 

0667: AS_actor @0 aim_at_point 969.3931 -1098.341 22.877 10000 ms

If actor has weapon, it'll just aim but doesn't shoot. If used on CJ, he'll just aim and won't be controllable except you can scroll through his weapons.

 

09C4: set_car @0 gas_tank_explosion 0

0=hit gas tank does't blow

1=hit gas tank blow up

Awesome find i've been looking for one to make actor aim

 

Have you found any to make actor start to swim ??

[Demarest]

Drop him in the water. Funniest moment I've ever had in SA playing it was when Rosenberg was madly swimming towards me to keep up.

[Craig Kostelecky]

But not all of the actors swim (if I remember right). Remember the mission where you have to drown the guy by driving off of the dock? There may be an opcode that triggers an actors ability to swim. But I haven't looked through the code yet to find it.

[spaceeinstein]

The actor naturally swims if it is in group with CJ (haven't tried if in every groups). If it is not, use this:

04D8: set_actor @0 ability_to_swim 0 (0=swim/1=Tommy)

 

And I found more stuff:

0668: AS_actor @0 rotate_to_point @1 @2 @3 10000 ms

0727: $helicopter $actor $vehicle 20.0

 

 

Makes the helicopter fly/behave like a police copter it will follow the $actor or $vehicle but it will still target you if you are near it and have a wanted level.

[robbo-theman]

0727: $helicopter $actor $vehicle 20.0

 

 

Makes the helicopter fly/behave like a police copter it will follow the $actor or $vehicle but it will still target you if you are near it and have a wanted level.

actually 0727 should be engage code since it makes maverick follow you shot at you no mather of wanted level. It is tricky since maverick have no guns. It simulates crew onboard which opens fire. It is code for maverick type heli while other heli types have some fly difficulties with. The car in code should be not empty (crashes game). However if you engage some actor in car it makes maverick shot at you (at least by me). last parameter is an altitude in the way that heli fly exactly that much higher than player actually is.

I tested also some other codes regarding to flying vehicles and the codes have always "range" but that is not a range that is again altitude as above. If there is two parameters- altitudes too (low and high levels). If i am not mistaken.

Didnt happen when I tested it

 

 

 

It is tricky since maverick have no guns.

 

I didnt test it on the Marverick I tested it on the Rain Dancer and the Sparrow

 

 

 

It simulates crew onboard which opens fire.

 

 

I don't think it works without an actor onboard and BTW the "crew" doesnt talk unless you have a wanted level.

 

 

 

It is code for maverick type heli while other heli types have some fly difficulties with.

 

List the heli types

 

 

The car in code should be not empty (crashes game).

 

Thats why you add -1 if you don't have a target car and vice versa if you don't have a target actor.

 

 

 

However if you engage some actor in car it makes maverick shot at you (at least by me).

 

 

I'm not sure what you mean.

 

 

 

last parameter is an altitude in the way that heli fly exactly that much higher than player actually is.

 

I know

 

 

I tested also some other codes regarding to flying vehicles and the codes have always "range" but that is not a range that is again altitude as above.

 

 

Testing a code made specifically for a helicopter on an airplane will have very funky results. Keep that in mind

 

 

If there is two parameters- altitudes too (low and high levels). If i am not mistaken.

 

?

[robbo-theman]

Well it happens by me all the time.

The thing about altitude is: all known opcodes regarding flying vehs following ya have "range" and it is not a range- my suggestion is to change it.

I meant empty car like @1 would be an empty car- see what happens if you try.

If you exchange target group of vehicle type in code it will never fly or drive or whatsoever - that should not be funky.

I am trying to help with the code by retesting it you know.

ah, use it with hunter and you will notice: this code engages not primary or secondary weapon system it makes any vehicle shot like police maverick does.

[BBumper]

 

Well it happens by me all the time.

 

It either shoots you with a wanted level or not, from what I've observed it doesnt hit you with the spotlight, shoot or bother you unless you 'tell' it to in addition to having a wanted level and I'm sticking to that until I read a different opinion from a more experienced member, as for altitude and other useless minutia I really don't care.

 

 

The thing about altitude is:...<SNIP>.

[robbo-theman]

yes...cute

quotes:

070E:

orders hadra (horizontal thrust) to engage mobile_player (only when in vehicle) with primary weapon

0710:

orders airplane (horizontal thrust) follow, in my tests only follow

this one:

08A2:

orders hydra (horizontal thrust) to engage player regardless, with primary weapon

but they require some pre-sets

0745:

will set thrust for hydra horizontal if i remember corectly

0742:

will order air veh to keep altitude, counted 1.0 = 1 bar

could you confirm?

 

btw. with wanted lev., it can be you have differend results, i think i have set 03A2: to 3 for my tests

edit: did not found correct meaning for these opcodes here before

Edited December 21, 2005 by robbo-theman

(Snip)could you confirm?

 

I suggest you actually look at the opcode database and look over this thread before flagrantly mucking over others hard work.

 

You probably mean well but please do a little more searching, research & testing to see if the opcode you're posting about has been covered before..

More stuff:

07AC: detach_trailer @0 from_cab @1

08CB: char_car @0 sound 0 0 0 (it doesn't have explosion, 1 1 1 makes sound of explosion)

0337: set_actor @0 visibility 0 (0=invisi/1=visi, cj cant)

0489: set_actor @0 audible 0 (0=talkative/1=quiet)

0635: AS_actor @0 aim_at_actor @1 10000 ms

 

0730: damage_car @0 component 0

073C: damage_car @0 component 0

Those two does exactly the same thing.

For 0730:

0 - hood

1 - trunk

2 - driver door

3 - front passenger door

4 - left rear door

5 - right rear door

6 - left bulb

7 - right bulb

8 - ???

9 - ???

10 - window

11 - front bumper

12 - rear bumper

 

For 073C, left bulb start with 0, then right bulb as 1, and keep going through the list above with different numbers.

 

I first saw this from Pavel but this wasn't in here:

0825: instantly_spin_flying_vehicle @0 rotor_blade (don't use on other vehicles)

 

I realize that if you put a driver into a trailer, the trailer would not connect. I accidentally placed a driver in the Petrolium trailer and the Tanker wouldn't attach it.

070A: unknown_action_sequence $actor $object  X Y Z Int1 Int2 "NULL" "NULL" -1

 

Links an object to an actor, by the bone.

actor - actor to link the object to

object - object to be linked, can be anything thats definrd in the object list, in the scm

XYZ - offset to bone to attach object too (see next line)

Int1 - Bone index of character that object is linked to (see below for values)

Int2 - Rotation values of some sort, though i only saw "16" for a lot of the lines i checked

"NULL" - unknown

"NULL" - unknown

-1 - unknown, duration of time for object to be linked?

 

Bone index values-

0 - crashes game

1 - chest?

2 - neck?

3 - left shoulder

4 - right shoulder

5 - left hand

6 - right hand

7 - root?

8 - ??

9 - left foot

10 - right foot

11 - right knee

12 - ??

13 - left elbow

14 - right elbow

15 - left clavicle

16 - right clavicle

17 - back of neck

18 - mouth or chin (if mouth, then object rotation got screwed)

19 - crashed game

 

I tested initially with the cigar, but that made it really hard to see since its so small. So i tried the Barrel! for bones with a "?" on the end, and it is still linked, i just don't know which specific bones. looked mighty goofy with a barrel sticking through the neck

 

Some notes:

if you punch or kick an actor linked to an object, or if you kill them, the object will be unlinked, and depending on what is is, destroyed.

You cannot give an actor a gun AND link an object to them - the linked object will always get precedence, and they will not be armed. if you kill them, you can still get their weapon as a pickup though.

If you link an object to the player, and THEN go over a weapon pickup, you will keep both your linked object, and the weapon, but the weapon model will be invisible.

In the screenshot with the barrel, the object in his hand is NOT solid - shooting it does nothing. However, if you shoot the *actor*, they will drop their object, and then the object will become "active", and solid.

[Quadropheniac90]

Pretty cool! Is there still a Vice City Opcodes topic open or not? Or should I post here?

 

I want to know if there is a possibility that IFP files can be loaded and an animation, chosen from the file, can be done? I bet that requires memory hacking if even possible. Some help here please, I want to enable different types of animations for the player.

Opcodes for Bartons Editor

 

The original OpCode topic (or at least an old one).

[DeeZire]

I don't think this one has been posted yet, it's only used once in the whole main.scm;-

 

 

09E9: activate_nitrous_on_car $carID

 

 

Same effect as when you are in a car and activate the NOS. Car must have NOS installed on it for this opcode to work, and it appears to 'exhaust' all remaining NOS boosts in one shot - when I triggered this on a car with 10xNitrous, I had none left after using this opcode on it once.

 

And another one;-

 

 

0843: get_zone_name_from_coords $x $y $z as_string $s

 

 

Gets the zone name from the specified co-ords (x,y,z) and places that name into a string variable.

 

Couple of shop-related ones, not completely tested under all conditions but they worked for me intially at least;-

 

 

09A9: assign_buyable_item "$string" to_id $int

 

 

Gets the buyable item ($string) from shopping.dat and assigns it an ID (the $int parameter).

 

 

08C8: reset_buyable_item $int1 price_to $int2

 

 

Sets the item ID ($int) to the price specified by $int2, can be used to override the default price set in shopping.dat.

 

Example from clothes.scm;-

 

 

09A9: assign_buyable_item "TSHIRTLOCGREY" to_id $1002108C8: reset_buyable_item $10021 price_to 15

 

 

And another;-

 

0393: actor $actorID perform_anim "ANIM" at $var times_normal_rate

 

 

Makes the actor perform the specified animation at $var times the normal speed. Actor must already be peforming the animation, so use opcode 0611 to check it first.

 

Another;-

 

097C: link_wav $int(1-4) to_object $objectID

 

 

EDIT: is it just me or does opcode 03AA: no longer work in SA (play_suspect_last_seen_at)? Or is there a glitch in the Vigilante code?
