Hello/Guidance Request

Okay, I don't speak a word of Russian so I give myself kudos for being able to register so fast. I thought there was no better place for modding information than GTAForums, but then I saw this place!

I've read a few things and it's already given me the inspiration to make new mods as well as showing me how.

I've been coding for a while now and I'm getting to the stage where I'm bored of the opcodes given to me. I use memory addressing from time to time but besides from that I have no clue how to use many functions in the San Andreas .exe.

After reading a few topics I've got the idea that a few different coding techniques can be used in CLEO Scripts (?) such as ASM, Delphi etc(?). Well I don't know which one I need. All I've ever done is a bit of C++/Basic and a heap of web languages. I've always wanted to break into C++ but due to my fondness of GTASA, it's changed into wanting to learn something that I can make scripts in that with.

So if anyone knows what technique I'm better of starting with, and then teaching me some basics in which I can go on learning then I'd be a happy person If there are any tutorials in existance, point me in that direction with my tail between my legs... No references intended.

Ops! Yes, sorry I forgot that I have all my display site infromation in Russian. I forget that not very one understands Russian. Are you able to read your/my profile information, or is it still in Russian for you? And thank you for the nice comment, it's very nice to hear.

There are tut's on the Microsoft website on C/C++.

As for what you should start off with, I recommand first to try and use a ASM injector in your script. There are two topics for this (as you problay read)

• One in the SA Memory Topic
  
• One in the Russian forum (in Russian!)
  

Delphi codes are for Delphi, it's a programming tool, the same Sanny Builder was written in. ASM, yes but these for main.scm, we have even better ways to pull of the function when we use CLEO.

You said about functions in the .exe file, there is a huge list of them, that Seemann & listener created, I can give you a link to the TXT-file, but as for the topic - again in Russian language.

Heh, that's okay. I should be the one saying sorry. Besides, it's me who only knows one language and you who knows 2. Us english speaking peoples are lazy, lol.

I can always use Google Translate to view the pages in english. And then confuse you all with my badly translated Russian

Your profile is in english besides from the Location & Job/Hobby fields.

I'm finding that the Russian/Japanese sites are the ones to check out when it comes to advanced coding. Only problem I have is that Google searches english sites over everything else.


I'm confused when it comes to the memory address wiki's.

1. What is the difference between function and normal memory addreses? And how do I use each of them correctly. (I believe you use them differently?)

2. That isn't a full list, right? I've seen addresses used which I can't find listed there.


My main priority is trying to find out what stuff like this means:

Code:

0A9F: 0@ = current_thread_pointer
000A: 0@ += 0x10
0A8D: 0@ = read_memory 0@ size 4 virtual_protect 0
000E: 0@ -= @Dialog_Text
000A: 0@ += 4
0085: 1@ = 0@ // (int)
000A: 1@ += 31
for 31@ = 0@ to 1@
  0A8C: write_memory 31@ size 1 value 0x20 virtual_protect 0
end

(Rysuke's mission loader, lol.)

And be able to write stuff like that without having someone to hold my hand...

Speaking of which, I've been trying for days to learn how to write a keyboard script in San Andreas... Like the one in the Mission Loader. I've got the original source and I still can't figure out what I need.

All I know is that AAAAAA(...) is the changable text and 0000: NOP turns it into the entered text. I don't know how the keys are retrieved, converted to letters and added to the text box. If I could figure that out, I'd be able to make alot of mods with it

Also, big thanks to you for that 3 page topic full of examples. I needed the address to fix a headlight and I thought I was never gonna get one. But yeah, I managed to bump into your topic. Gonna improve Vigilante Justice with it now...

Heh, that's okay. I should be the one saying sorry. Besides, it's me who only knows one language and you who knows 2. Us english speaking peoples are lazy, lol.

Actually, more than 2.

• Russian
  
• German
  
• Ukrainian
  
• Japanese
  
• English
  

I can always use Google Translate to view the pages in english. And then confuse you all with my badly translated Russian

Ха-ха, я знаю ... (ha ha, I know) Google is a machine made translator, so it's the best possible at this stage, it's very bad in translating Japanese ...

I'm finding that the Russian/Japanese sites are the ones to check out when it comes to advanced coding. Only problem I have is that Google searches english sites over everything else

Yes, I take it because we have more information, your computer searches English ones, because Google deafult search is set to English on your computer (must be), try to change it

1. What is the difference between function and normal memory addreses? And how do I use each of them correctly. (I believe you use them differently?)

A function address is something you call, a memory address is usually something you read or write to.

2. That isn't a full list, right? I've seen addresses used which I can't find listed there.

It's almost a full list of memory functions not memory addresses (per say).

Speaking of which, I've been trying for days to learn how to write a keyboard script in San Andreas... Like the one in the Mission Loader. I've got the original source and I still can't figure out what I need.

Ryosuke is getting the keys of the keyboard and when you type them it writes the message. Yes, he is complex, but his scripts are easy to understand if your reading the source, and you have exp. with memory handling/hacking.

All I know is that AAAAAA(...) is the changable text and 0000: NOP turns it into the entered text. I don't know how the keys are retrieved, converted to letters and added to the text box. If I could figure that out, I'd be able to make alot of mods with it

It's not the AAAAA part which does this ... it's all of Ryosuke's scrpt which does. AAAAAA (...) is used because this can mean anything, it would not work if Ryosuke put something like ***** for example.

Also Ryosuke posted his source code there if it helps:

http://ryosuke.my-sv.net/mapmod/cml/cml.txt

Also, big thanks to you for that 3 page topic full of examples. I needed the address to fix a headlight and I thought I was never gonna get one. But yeah, I managed to bump into your topic. Gonna improve Vigilante Justice with it now...

It's no problem... more to come soon, sure.

I read Ryosuke's source but I can't figure out what I need from it. I have no idea what the addresses do either...


I tried stripping it down. But I'm having trouble on the keypresses. So far there is just an empty box waiting to have stuff put in it. Note that if the wait at the bottom is removed, the text box will only show up for 0ms and keep getting removed...

Code:

snip

And someone from my forum tried:

But we can't get it to work so far. The box on this one won't show up. But I get a feeling data is still being sent to it.

Code:

snip

It's going well so far! I managed to fix a few bugs and the typing system works flawlesly. The only problem is that to keep the text box on screen the text box function needs to be called over and over...

The one problem that persists is making the spacebar and backspace function properly...

Also, random text appears on the second line.
(seems to collect random variable names or somethin)

Code:

snip... (page was getting loong)

Also, random text appears on the second line.
(seems to collect random variable names or somethin)

Хмм, I will have a look at that. Yes, it does seem to "collect" some variable, but I am not sure, why that one.
It gets the active interior, you should use hex..end structure.

Code:


hex
"____________________"
"____________________"
"____________________"
"____________________" 00
end


for example, this has 4 lines, adding more lines of thw same size will make the text_box more big, it will also fix that "active interior" from showing. '00' is a null digit, it's used just so the hex..end structure its self does not appear.

Code:


:POINTER
0A9F: 0@ = current_thread_pointer
000A: 0@ += 0x10
0A8D: 0@ = read_memory 0@ size 4 virtual_protect 0
000E: 0@ -= @TEMP_MEMORY
return

:TEMP_MEMORY
hex
"____________________"
"____________________"
"____________________"
"____________________" 00
end


The parts you used in the script that skip 4 data-type bytes, because you used a opcode to store the text, you can delete if you this method, because there is nothing (no data-type (0900:)) to skip anymore, so all parts in the script that are used to skip the 0900 data can now be deleted.

In your script there is a trick from which Ryosuke, I, and some more use. Maybe that's something to do with it ... don't know - not tested.

There is a topic about data-storage in CLEO scripts, on a Wiki.

Varistor - ローカル変数の制限突破

the text box on screen the text box function needs to be called over and over...

Yea, this is a "real bitch", or something like that, what about display it once, check if any key is pressed (A-Z) and then display the text_box, again?

The one problem that persists is making the spacebar and backspace function properly...

~ Space bar ~

Code:


if and
    0AB0: key_pressed 0x20
then
  0A8C: write_memory 0@ size 1 value 0x20 virtual_protect 0
  0@ += 1
  0A8C: write_memory 0@ size 1 value 0x5F virtual_protect 0
  0@ += 1
  0A8C: write_memory 0@ size 1 value 0x0 virtual_protect 0
  0@ -= 1
    CHARS += 1
repeat
    wait 0
  until 8AB0: not key_pressed 0x20
end


~ Back space ~

Code:


if
  0AB0: key_pressed 0x8
 then
  0@ -= 1
  0A8C: write_memory 0@ size 1 value 0x5F virtual_protect 0
    CHARS -= 1
  repeat
  wait 0
  until 8AB0: not key_pressed 0x8
end


Should work.

cheers. I had to change it a bit to make it work... To be honest I can't believe I couldn't add them before. It was soo simple and I think I even nearly did it, but got the lines muddled up.



It seems to work perfectly. I even managed to add number support...

And I managed to get it to activate animations:

Code:

0605: actor $PLAYER_ACTOR perform_animation_sequence 0@ IFP_file "PED" 4.0 loop 1 0 0 0 time -1
0000:

Invalid entries crash the game though... Know of any way to ask the game whether an animation exists? Not just the IFP file, the animations inside.

Otherwise I'd have to add billions of checks for each anim in San Andreas. xD

Can't wait to find out. I've been working on a debugging script for a while... I never intended for it to be a full blown debugger... But I used it everytime I wanted to make a script to help me with something. Over time it's grown and grown...

So adding the feature to test anims as well as testing parameters of the animation opcodes would be great!

Also, any specific way of performing an opcode line in hexidecimal? Or would this work:

Code:

20 30 30 30 31 3a 20 35 30 30 30

= wait 5000 command?

If I can figure that out I could maybe code the abillity to get any opcode and test the hell outa it

Invalid entries crash the game though... Know of any way to ask the game whether an animation exists? Not just the IFP file, the animations inside.

Yes, I think somewhere, but why do not just check if the animation (0@) has loaded if not, don't make CJ perform, because if the entry is invalid then the animation will not be loaded - therefore no crash possible, all game versions will have the same animations in the gta3.img, (other than the animations used for 'Hot Coffee' which are not in v1.01 and higher). Put the loaded part in the loop before the player types the animation name on screen, if it's loaded jump to end the script or something like that.


If you want, you can write all animation names in NOP (opcode 0900) and read it from memory if the name is not either of these, jump to end the script or want you want to do. It's more hard enough.

Also, any specific way of performing an opcode line in hexidecimal?

You mean write a opcode using hex..end struct, instead of using the actual opcode? Yes, I do, for example:

Code:


D504030200030300030400060000803F0404040005FF0005FF0005FF005100


is like writing

Code:


04D5: create_corona_at 2@ 3@ 4@ radius 1.0 type 4 flare 0 RGB 255 255 255
0051: return


And this:

Code:


05AD: &0(1@,1s) == &@Thread(0@,1s)


Is the same as:

Code:


hex
AD05          // opcode      (05AD)
0C            // data type
0000          // array name  (&0)
0100          // index name  (1@)
0102          // size&type
0C            // data type
@Thread  // array name&index name (0@)
0102          // size&type
end


Just trying to make your script more complex, so that you can confuse people who don't understand this, and also make it so the mod is less likely to get stolen by someone else, huh?

I type in "ATM" and the game crashes... Yet before, when using the same code, it didn't. Since then I changed it but I changed it back again. So I don't know what's wrong.

OK, I see the problem now. I did not think you meant animations from the PED file which is loaded by .exe file.

Mmmm... That's not something I can manage to translate...

It's different. That one you use is used to translate "normal" hex input, but when we write opcodes in hex..end structure it's too hard for a number translation tool to convert. All it will give you is werid signs, like if you open a ASI/DLL file with the wrong program.

http://varistor.dyndns.org/wiki/index.php?%A5%B3%A5%ED%A5%CA%B4%D8%B7%B8

Maybe it just doesn't like 0@ in place of the string... If so, how would I make this work..?

^ lol Keyboard script?

It's kind of updated now but untested. :/

Code:

EDIT

Can someone verify if this works? It should be compiled as key-in.cs with "AS IS" for SB case-converting.

There's a hypothetical bug stemming from the arrow keys. I call it the "Insert Bug" because it acts like the Insert button on the keyboard (replaces the char after the cursor except this script currently has no cursor).

And sorry for the thread hijack. I just thought that since Deji was already talking about this script I should just continue with it.

EDIT - Doesn't work sorry.
