 |
|
Hey, i have this script:
| Code: | {$STRICT}
define(orig_bytes_godmode, 55 8B EC)
define(orig_bytes_block, 23 C3)
define(orig_bytes_ammo, 55)
define(godmode_patch1, Player:CharacterDamage)
define(godmode_patch2, Player:DealerDamage)
define(block_patch, AI:CharacterDamage+34C)
define(ammo_patch, RangedWeapon:DecrementAmmo)
[ENABLE]
{$lua}
if syntaxcheck then return end
if LaunchMonoDataCollector() ~= 0 then
if readInteger(godmode) == 1 then
local hook1 = mono_findMethod('Assembly-CSharp', 'Player', 'CharacterDamage')
local hook2 = mono_findMethod('Assembly-CSharp', 'Player', 'DealerDamage')
mono_compile_method(hook1)
mono_compile_method(hook2)
end
if readInteger(block) == 1 then
local hook = mono_findMethod('Assembly-CSharp', 'AI', 'CharacterDamage')
mono_compile_method(hook)
end
if readInteger(ammo) == 1 then
print(ammo)
print(readInteger(ammo))
local hook = mono_findMethod('Assembly-CSharp', 'RangedWeapon', 'DecrementAmmo')
mono_compile_method(hook)
end
end
{$asm}
assert(godmode_patch1, orig_bytes_godmode)
assert(godmode_patch2, orig_bytes_godmode)
assert(block_patch, orig_bytes_block)
assert(ammo_patch, orig_bytes_ammo)
alloc(godmode, 4)
alloc(block, 4)
alloc(ammo, 4)
label(godmode)
label(block)
label(ammo)
registersymbol(godmode)
registersymbol(block)
registersymbol(ammo)
godmode_patch1:
xor eax,eax
ret
godmode_patch2:
xor eax,eax
ret
block_patch:
xor eax,eax
ammo_patch:
ret
godmode:
dd 0
block:
dd 0
ammo:
dd 0
[DISABLE]
godmode_patch1:
db orig_bytes_godmode
godmode_patch2:
db orig_bytes_godmode
block_patch:
db orig_bytes_block
ammo_patch:
db orig_bytes_ammo
dealloc(godmode)
dealloc(block)
dealloc(ammo)
unregistersymbol(godmode)
unregistersymbol(block)
unregistersymbol(ammo) |
I want to put godmode, block and ammo addresses in table, and allow user to activate/deactivate them (1/0). If set to 1, mono_compile_method() gets called for appropriate option. I hope i was clear enough, so, how can i do this properly?

You can place the symbols in your table and set a dropdownlist with options
| Code: |
0:Disabled
1:Enabled
|
and the user can set them like that, but it wouldn't compile those methods from there by itself. To achieve that with DDLs you could just set up a timer in your above function, instead of checking the symbol's states when you enable the script. If you choose to use a timer, be sure to destroy it when the appropriate script is disabled.
Alternatively, you can use a script as the table entry:
| Code: |
[ENABLE]
{$lua}
writeInteger("godmode",1)
local hook1 = mono_findMethod('Assembly-CSharp', 'Player', 'CharacterDamage')
local hook2 = mono_findMethod('Assembly-CSharp', 'Player', 'DealerDamage')
mono_compile_method(hook1)
mono_compile_method(hook2)
{$asm}
[DISABLE]
{$lua}
writeInteger("godmode",0)
|
The latter would only work if you have godmode's symbol created already via a parent script, similarly to what you already have.
You can tweak these to make it work whichever way is more appealing to you.
The most conventional way would be to run a timer that checks these variables, if they exist/aren't nil, and do something based on that, but both methods work.

also, when the assembler does this code:
| Code: |
godmode_patch1:
xor eax,eax
ret
|
it already calls mono_compile on Player:CharacterDamage so you don't have to do that yourself

You do still need to initialize Mono to use the function names directly, and forcibly compile them if need be so you can inject. It depends what you're editing; if the functions run frequently anyway you should be fine, but seeing how these relate to damage you should probably do it anyway.

cheat engine forcibly compiles the method if you reference it, when mono tools are activated
