Suppose this is my script. What should I do with it.

Code:

[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

originalcode:
fstp dword ptr [edi+000002CC]

exit:
jmp returnhere

"crimsonland.exe"+1779E:
jmp newmem
nop
returnhere:

[DISABLE]
//code from here till the end of the code will be used to disable the cheat
dealloc(newmem)
"crimsonland.exe"+1779E:
fstp dword ptr [edi+000002CC]
//Alt: db D9 9F CC 02 00 00

I pasted this in my lua table but it did nothing.

Code:

myscript= [[//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

originalcode:
fstp dword ptr [edi+000002CC]

exit:
jmp returnhere

"crimsonland.exe"+1779E:
jmp newmem
nop
returnhere:]]
autoAssemble(myscript)

But it does nothing. What should I do?

Have you executed that lua script? Was a process opened with ce when you executed that script ? _________________ Tools give you results. Knowledge gives you control. Like my help? Join me on Patreon so i can keep helping

How to disable my script?
And how do I disable my script after 10 seconds?

Code:

myscript = [[alloc(newmem,2048) //2kb should be enough
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here

originalcode:
fstp dword ptr [edi+000002CC]
mov dword ptr [edi+000002CC],200

exit:
jmp returnhere

"crimsonland.exe"+1779E:
jmp newmem
nop
returnhere:

]]

offscript = [[dealloc(newmem)
"crimsonland.exe"+1779E:
fstp dword ptr [edi+000002CC]
//
]]

timer = createTimer(nil,true)
timer_setInterval(timer,20000)
i=1
function onhere()
autoAssemble(myscript)
if i==1 then
timer_onTimer(timer, offok)
i=2
end
end

offok=function offhere()
autoAssemble(offscript)
end

onhere()
