the opcode that writes the value is 02000000 - 89 41 30 - mov [ecx+30],eax

if you meant like you wanna write 02000000 decimal to the memory-location of [ecx+30]
then you can do it this way:
mov [ecx+30],#2000000

if 02000000 is an address then the basic idea would be to write a code injection at 02000000, but since a jmp typically needs 5 bytes and that mov is only 3 you'd need to overwrite another instruction as well.
Alternatively you could use lua to set a breakpoint, step (so that the mov is executed) and then write to ECX+0x30 yourself, but if it's something that runs a lot then that's going to cause issues because the context switching involved with breaking, running lua, continuing, (repeat) is quite slow. But if it's just once every few seconds then it should work ok.
something like Code: | if not debug_isDebugging() then debugProcess() end
debug_setBreakpoint(0x02000000, function()
debug_continueFromBreakpoint(co_step) -- execute mov
writeInteger(ECX+0x30, 9999) -- write 9999 to ecx+30
debug_continueFromBreakpoint(co_run) -- continue running
end)
|
edit: I think you could also just change the value of EAX and then continue....might be the better method

the code worked it changed to one color permanently. How do I make into a script that changes into 5 colors without me doing anything. I tried to freeER's code and got an error in saying it can't be compiled. what should I paste in the auto assemble script?

What FreeER gave you is Lua, this is the Cheat Engine Lua Scripting section, but I am pretty sure that Cheat engine only says that for Auto Assembler scripts that fail syntax check. And what OldCheatEngineUser gave you was ASM for an Auto Assembler script. So is this a Lua script or an AA script.

i meant for auto assembler script. I want a script that changes to 5 different values for this address without me pressing anything. was about to post in auto assemble script section but its locked.

So to use what FreeER gave you you would need to tell the Auto Assembler that the code is Lua, this is doen with "{$lua}".
Code: | //// ASM code
{$lua}
-- Lua code
{$asm}
//// Back to ASM |
Code: | [Enable]
{$lua}
if not debug_isDebugging() then debugProcess() end
debug_setBreakpoint(0x02000000, function()
debug_continueFromBreakpoint(co_step) -- execute mov
writeInteger(ECX+0x30, 9999) -- write 9999 to ecx+30
debug_continueFromBreakpoint(co_run) -- continue running
end)
-- ...
[Disable] |
But I think he may have meant for this to go into the cheat table Lua form.
And to do it in AA you would need to write an injection script or create a thread with a loop. And you would still need to enable the script.

this is my code auto assembler code. where should I paste this Tim?
[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
newmem: //this is allocated memory, you have read,write,execute access
//place your code here
originalcode:
mov [ecx+30],eax
lea ebx,[ebx+000000AC]
exit:
jmp returnhere
02000000:
jmp newmem
nop
nop
nop
nop
returnhere:
[DISABLE]
//code from here till the end of the code will be used to disable the cheat

That is an Auto Assembler script, from the Memory View form, "Alt+A" or tools -> Auto Assembler. Then File -> add script to table. And that will give you a script memory record that you can save to the table.
You may also want to look at the Auto Assembler Templates menu item. And look into AOB scripts. Just select the instruction in the Memory View form where you want to inject before generating a template.
EDIT:
And just add some thing like what I have here under the "newmem:" line and before "origialcode:"
Code: | [ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
newmem: //this is allocated memory, you have read,write,execute access
//place your code here
mov eax,(int)200 // or what ever decimal (base 10) value you want
originalcode:
mov [ecx+30],eax
lea ebx,[ebx+000000AC]
exit:
jmp returnhere
02000000:
jmp newmem
nop
nop
nop
nop
returnhere:
[DISABLE]
//code from here till the end of the code will be used to disable the cheat
02000000:
mov [ecx+30],eax
lea ebx,[ebx+000000AC]
// This will disable the cheat when disabling the script, a lest if the value is corrected some where by the game

The code that FreeER posted can go in the table Lua script, main form -> Table -> Show table Lua script. But that is just writing to the value using breakpoints and the AA script dose it with an injection, so you should only need one.

Not sure what you mean. But there is this in the "celua.txt" file in the cheat engine folder.
Quote: | doKeyPress(key) : simulates a key press |

Code: | mov eax,(int)200 // or what ever decimal (base 10) value you want |
200 in decimal (base 10), is C8 in hexadecimal (base 16)
If you want to set it in hex just remove the "(int)" part.
At this point I am going to suggest that you try the Cheat Engine tutorial in the Help menu section, I think you may have better luck next time if you do.
