GTA SA/VC/III: How to create a cheat code!

[bananaking13]

Hesoyam, Rocketman, monstermash... Some of the greatest GTA memories were writing cheat codes on a papers, and losing the paper would mean you go to a website and keep writing.

 

Now here is how you can make a cheat code:

We'll open up with our first line. We'll open a thread: Keypress1.

 

:KEYPRESS1

Now we put if or.

:KEYPRESS1if or

Next up is the letter we pick. For a list of letter codes, open the spoiler

 

Yes, you can put a spacebar unlike the normal GTA game but I have never tested if it works, and I personally don't recommend it.

32 = Spacebar

65 = A

66 = B

67 = C

68 = D

69 = E

70 = F

71 = G

72 = H

73 = I

74 = J

75 = K

76 = L

77 = M

78 = N

79 = O

80 = P

81 = Q

82 = R

83 = S

84 = T

85 = U

86 = V

87 = W

88 = X

89 = Y

90 = Z

 

We're going to do the cheat code "BOATMAN", which will make your lung affinity maxed out.

So the next part of the code you have to get the player to wait 0 ms to prevent a crash loop, then jf the KEYPRESS1 thread. after that you jump to KEYPRESS2. For perfect example look at this..interesting thing below

:KEYPRESS1if or0420:   key_pressed 66 //B wait 0 msjf @KEYPRESS1jump @KEYPRESS2

See, here we execute the first letter. B. Now for the next, which is O.

 

When you do all the letters except first and last, you have to do a different formula. The first and last one are different too.

:KEYPRESS2while trueif or0420:   key_pressed 79  // O wait 0 msjf @KEYPRESS2jump @KEYPRESS3:KEYPRESS3while trueif or0420:   key_pressed 65  // A wait 0 msjf @KEYPRESS3jump @KEYPRESS4:KEYPRESS4while trueif or0420:   key_pressed 84  // T wait 0 msjf @KEYPRESS4jump @KEYPRESS5:KEYPRESS5while trueif or0420:   key_pressed 77  // M wait 0 msjf @KEYPRESS5jump @KEYPRESS6:KEYPRESS6while trueif or0420:   key_pressed 65  // A wait 0 msjf @KEYPRESS6jump @KEYPRESS7

Here we have finished the entire cheat code line but only one thing is left: the closing line

:KEYPRESS11while trueif or0420:  key_pressed 78  // N wait 0 ms  jf KEYPRESS1107AA: show_permanent_text_box 'Cheat Activated.'07AA: change_integer_stat 225 to 1000  // lung capacity 

Explanation to everything post-jf KEYPRESS11

07AA: show_permanent_text_box 'Cheat Activated.'

Now SA does not think that this is a cheat code: All it does is you write it and a small effect happens. So to make the player say "yeah that's a cheat code!" you do this.

07AA: change_integer_stat 225 to 1000  // lung capacity 

Now this basically just does the code effect. The ID for lung capacity is 225. The maximum level is 1000. Not hard, right?

Nice tutorial, but I'm left with 2 questions now.
1. Is this a cleo script?
2. Where is the code for the original cheats located? [i want to see the code for the orignal cheats from GTA: VC]

You have to compile the script into your cleo directory as what ever you want to name it but the file extension has to be .cs and original cheat codes can be found in GTA SA/VC/III exe (Decompiled tho)

[spaceeinstein]

This tutorial is bad. The example used the wrong opcodes, it is incomplete, and opcode 0ADC already exists specifically to let you create cheats.

see my video with cheats, cars and much more.

No point of this big cleo script to make a cheat while we can do it with 0ADC

Why don't people make cleo tutorial videos on gta 3?
