 Posted: Sun Apr 07, 2024 12:36 pm Post subject: Custom Auto Assemble template uses Mono Symbols |
 |
|
Following my previous post ( https://forum.cheatengine.org/viewtopic.php?t=622250 )
I managed to find and edit a template that works.
However, if Mono features are active and i let the Auto Assemble use my template, it will use the Mono Symbols, thus failing or even throwing errors.
Same goes for the originalcode part (it uses the Mono symbols instead of the actual addresses).
Otherwise, if Mono Features are not active, it works properly.
The default AOB Injection template of CE uses the actual Addresses regardless of the Mono activation. I dug into the GitHub repo and managed to find only a .pas file containing the source code for it, but eventually i came across a .lua template that i modified (i just modified the first part of it, not the actual script generation)
This is the .lua
| Code: |
myAOBInjectionTemplates = {}
myAOBInjectionTemplates.Templates = {
{
displayName="AOB Injection Custom",
submenu='Test',
templateSections=
[==[
<<ENABLE>>
{$LUA}
if not getAddressSafe("aob_%cheatName%") then
return [[
aobscan(aob_%cheatName%, %moduleNameC%%searchPattern%)
registersymbol(aob_%cheatName%)
]]
end
{$ASM}
alloc(newmem_%cheatName%,$1000%CmoduleName%)
label(return_%cheatName%)
newmem_%cheatName%:
%_originalCodeLines%
jmp return_%cheatName%
aob_%cheatName%%aobAdjust%:
jmp newmem_%cheatName%
%_nopLines%
return_%cheatName%:
<<ENABLE_END>>
<<DISABLE>>
aob_%cheatName%%aobAdjust%:
db %originalBytes%
dealloc(newmem_%cheatName%)
%additionalInfo%
<<DISABLE_END>>
]==]

I suppose the --Mono & Hook Address section is the culprit, but honestly i have no clue about it.
Edit: I found another post where the issue was already being discussed.
