Posted: Sun Mar 02, 2014 12:30 pm Post subject: Using Lua engine to scan for a particular value? |
|
|
Hi.
To get me started with CE Lua I wanted to try and perform something with a script that I normally do with the Scan feature.
In a game I play, I perform a scan for a float value with the value of 1000000. I then change all the results to zero.
I tried to build a script to do this, however it isn't returning any values. Can someone tell me what's wrong?
local scan = createMemScan(true)
memscan_returnOnlyOneResult(scan,true)
memscan_firstScan(scan,soExactValue,vtSingle,rtRounded,"1000000",nil,0,0xffffffffffffffff,"",fsmNotAligned,nil,false,false,false,false)
memscan_waitTillDone(scan)
local result=memscan_getOnlyResult(scan)
if result==nil then print 'LOL' else print 'WE GOT IT' end
(The output is LOL)

Took a test program, wrote 1000000 as float somewhere, and ran your script. The result was "WE GOT IT".
Did you forget to attach CE to your target?

Nvm, I modified it and it now works - you were right about me not attaching it.
Thanks for your help.
How would I program CE to change all the values to 0?

Code: | --Scan
local scan = createMemScan(true);
scan.setOnlyOneResult(false);
scan.firstScan(soExactValue,vtSingle,rtRounded,"123456",nil,0,0xffffffffffffffff,"",fsmNotAligned,nil,false,false,false,false);
scan.waitTillDone();
--Fetch result
local FoundList=createFoundList(scan);
FoundList.initialize();
--Overwite
for i=0,FoundList.Count-1 do
--print(FoundList.Address[i]);
writeFloat(FoundList.Address[i],0.0);
end
--Cleanup
FoundList.deinitialize();
FoundList.destroy();
FoundList=nil;
scan.destroy();
scan=nil; |
BTW: the documentation for all CE lua function can be found in the main.lua contained in your cheat engine directory.

Thanks, it did work.
However when I use the script (even if I don't put in the clean up part) the game crashes after a couple of seconds, I tried doing it manually and it didn't cause it to crash. Do I need to put in some wait() s?
--Scan
local scan = createMemScan(true);
scan.setOnlyOneResult(false);
scan.firstScan(soExactValue,vtSingle,rtRounded,"1000000",nil,0,0xffffffffffffffff,"",fsmNotAligned,nil,false,false,false,false);
scan.waitTillDone();
--Fetch result
local FoundList=createFoundList(scan);
FoundList.initialize();
--Overwite
for i=0,FoundList.Count-1 do
print(FoundList.Address[i]);
writeFloat(FoundList.Address[i],0.0);
end
--Cleanup
FoundList.deinitialize();
FoundList.destroy();
FoundList=nil;
scan.destroy();
scan=nil;

Try:
scan.firstScan(soExactValue,vtSingle,rtRounded,"1000000",nil,0,0xffffffffffffffff,"+W-C",fsmNotAligned,nil,false,false,false,false);
instead of:
scan.firstScan(soExactValue,vtSingle,rtRounded,"1000000",nil,0,0xffffffffffffffff,"",fsmNotAligned,nil,false,false,false,false);
