Anybody knows what things this opcode checks?

 

 

88B4:   not test $390 bit 1

88B4:   not test $390 bit 1 

 

 

This opcode will evaluate the specified variable and return the value of TRUE if the 2nd bit is NOT equal to 1.

 

Binary number: 11111111111111111111111111111101, the 2nd bit is NOT 1 -- so the statement is true.

 

Very few routines in San Andreas use bitmask flags. They are used (almost) exclusively by the various dating routines. Global variable $390 is used in the flow control of the dates. $390 bit 1 flags that the GF_Date routine is active -- CJ is on a date.

 

So, as used in the standard script:

 

88B4:if   not test $390 bit 1 jf @POOL_439 0209: [email protected] = random_int_in_ranges 0 2 

 

 

Means that: If CJ is not on a date (if he is then jump to the label @POOL_$439) then set [email protected] to a random number between 0 and 2 and continue.

The meaning of 020D is inverted. It should be:

 

020d=1,  car %1d% unflipped

 

It probably returns true whether a wheel touches the ground.

[Silent]

It probably returns true whether a wheel touches the ground.

I doubt it, as 09D0 already exist

 

But yeah, 'flipped' opcode returns true when the car is upside down (both in air and on ground), so it may be a inversion of this opcode (...both in air and on ground). Deji will surely update it in v2.

I don't know, does anyone else know it, but...

 

016F: create_shadow_type 3 rotation [email protected] size 2.0 intensity 255 RGB 255 0 0 at [email protected] [email protected] [email protected]

 

The second param is an angle in radians.

To convert degrees to radians:

 

0174: [email protected] = car [email protected] Z_anglediv([email protected], 57.2957795) //degrees to radians

016F: create_particle 1 makes shadow on the ground

I do not need help on it. I just noticed that "rotation factor" means angle in radians.

ups, was confused, i tried something with

0174: [email protected] = car [email protected] Z_angle

div([email protected], 57.2957795) // DEGREE TO RADIAN

but got only weired values

 

I would like to see what you mean but your script snippet have to much unknown variables

amazing which file contains the handman?

[Wesser]

It's the particle.txd file. This may be fix the lag with no other glitches (I believe).

[DK22Pac]

@Wesser

I used your code for making tailight)

Works fine, but sometimes camera is "jigging" (like when you are stand at car and start run to it).

Edit: OK. Maybe it caused because of other scripts which manipalated camera.

Uh, just a friendly heads up, but this is the wrong section-we have a seperate section for IV modding(this one is for III modding ONLY). You posted screenshots of IV, which means it needs to be in the IV Modding section.....

The behavior of opcode:

 

 

83D9:   not save_done

 

 

...is such that it checks if the player has exited the save menu (after saving or cancelling regardless).

 

Is there a method/opcode/hack to check if the game was actually saved or just canceled - to determine which?

 

Thanks,

-Midnightz

i assume it checks only for one time, like this meaning: "if user ever made a save"

i don't know any way to check if a save was done again but the save script of origin main.scm make the player first frozen which can be checked

It returns true always when user came back from Menu >> Save game, because it`s really set up by 03D8 opcode.

03D8 - set menu.isSaveDone, pause game, go to "save game" menu

03D9 - should happen when the game is resumed, user came back from "save game" menu. It doesn`t determine whether user made a save, but whether 03D8: show_save_screen was executed currently.

The game automatically resets menu.isSaveDone to 0 after the first processing SCM scripts.

 

 

    case 0x3D8:     if ( getPlayerPed(-1) )     {       v132 = getPlayerPed(-1)->PedFlags.Flags1;       if ( !(BYTE1(v132) & 1) )       {         menu.isSaveDone = 1;         v133 = (CPhysical *)getPlayerPed(-1);         CPhysical__setSpeed(v133, 0.0, 0.0, 0.0);         v134 = getPlayerPed(-1);         sub_45AFB0(v134, 0, 0, 0);       }     }     return 0;   case 0x3D9:     if ( menu.bIsActive || (v151 = 1, menu.isSaveDone) )       v151 = 0;     CScriptThread__setCondResult(a2, v151);     return 0;

Technically converting degrees to radians is (x*pi)/180 but 180/pi is ~57.29 so you can use that to some extent, though in pure mathematics the result is incorrect after a certain number of decimal places.

[Midnightz]

Thanks for the replies and help guys.

 

fastman92, if I'm reading that code right, it's just checking if the game reset 03D8 to 0, correct?

 

I'm not trying to intercept the original script to determine if the save menu was opened. I need some way of checking if an actual save was made or if the player canceled from the save menu.

 

Why: I've written a code similar to the original for a new savepoint. My code advances time 6 hours, the same as any other save works. The problem is that I have no way of determining if a save was made or saving was canceled and my code, without that type of check, advances time for both scenarios.

 

 

EDIT: I guess a better way to put it is this... How can I determine what the player selected in the save menu? A Save Slot OR Cancel.

Edited January 14, 2012 by Midnightz

[fastman92]

I have no time for this. It is possible when you patch some menu routine.

Edited March 9, 2012 by DK22Pac

If yeh wanna check if the game has been saved, you could compare the save path: 0xC15F60

Or the save file handle: 0xC16EF0

You're in the wrong topic, and it'd be best not to ask for help without first showing proof of progress so people would be inclined to help you.

 

And payment, I'm sure, isn't enough to entice people to help you out as most modders are intrinsically motivated to create mods, and adding money as a factor in this only complicates matters.

Opcode 0876 created birds, but it is written a bit wrong internally, oh R* programmers...

 

Ignore the bird color in red

 

 

0876: create_birds_at 0 0 0 destination 0 0 0 birds_count 3 bird_type 0

 

 

 

04C4: store_coords_to [email protected] [email protected] [email protected] from_actor $PLAYER_ACTOR with_offset 0.0 3.0 2.0008C: [email protected] = float_to_integer [email protected]: [email protected] = float_to_integer [email protected]: [email protected] = float_to_integer [email protected]: create_birds_at [email protected] [email protected] [email protected] destination -2630 1411 28 birds_count 3 bird_type 0

 

 

The opcode expects integers instead of floats in the coordinates params, If you see in main.scm the opcode send floats as coordinates and then the bird will be spawned in some crazy place (and then removed since it's too far from the camera).

 

Destination only serves to describe the bird angle...

[Deji]

Haha. Fun find (I'm sure this was supposed to be in the SA opcode topic, though ). I actually thought it was to block birds in a specified area, but had doubts due to the integer params and thought it might block more than one thing. Never bothered to actually test it, though. Just theorized a lot
