[2.2]Programmable AI via scripting

[totokwok]

sorry, may I ask how to write the script so that the AI will do D>J when target is on his right and D<J when target is on his left? (no matter which direction they are facing) Thank you very much.

Hi, of course you may . Welcome to LFE. In the future you should make a separate thread for any questions you have (so this thread doesn't get cluttered).

You can do it by reading the x variable of self and target. If target.x > self.x then you should do DrJ() else you should do DlJ() . In code form this looks like this:

Code:

if (target.x > self.x)
{
    DrJ();
}
else
{
    DlJ();
}

If you were a perfectionist you could change to an else if ( target.x < self.x) and add another else to decide what to do if they are on the same x. The version I posted will do D<J if they are on the same x coordinate.

• You can now access even more information using.
  
  • You can access the oid of an opoint like this:
    "game.objects[self.num].data.frames[self.frame].opoint.oid"
    
  • The Info structure (self, target), now has a data entry too. The following will give the same result as the above:
    "self.data.frames[self.frame].opoint.oid"
    
  • If you want a full list, either wait till someone else (as in, "not me"), compiles a complete list, or download the source code, and check out "sgame.h". (basic C syntax may be needed to understand it)
    
• You can now define Info structures like this:
  "Info some_ball;"
  
  • You can load them like this:
    "some_ball = 123;" (123 can be replaced with any number from 0 to 399)
    You can also check if it went well like this:
    "if((some_ball = 123) == -1)"
    
  • As a result of this you can do the same with target:
    "target = 123;"
    
• In addition to scripts with valid id numbers as a name (-1.as, 0.as, 1.as etc.), files that start with an underscore (_), are also compiled at startup.
  
  • This is useful for sharing variables between scripts. (more on this later)
    
  • If a file is compiled this way "module" will be defined. Otherwise "character" is defined.
    

I will soon update my Data Changer, so it will include color coding for the changes.

working on a list for the data struct

• As a result of this you can do the same with target:
  "target = 123;"
  

so that's basically like loadTarget(i) except allowing multiple ones with any name we want?
that will make my basic AI a lot easier to handle

• This is useful for sharing variables between scripts. (more on this later)
  
• If a file is compiled this way "module" will be defined. Otherwise "character" is defined.
  

could you mash up a quick example for this?


edit: game.objects[self.num].data.frames[self.frame].opoint.oid
this example does not work

this one does:
self.data.frames[self.frame].opoint.oid

Fixed.

Pretty much appreciated. Good job and Thanks ^^.
Also, did you guys figure a way to make the armor work? Do u think its even possible?
I really wanna help you with what you're doing, but i guess I need some more time to grasp what you've learnt before (these reverse engineering and hex stuff). Thanks again!

In this thread, you posted a method for patching the exe to load rarara.dll. But this dll seems to work without any patching in LF2.exe (v2.0a). I am interested in knowing how.
Also, does this dll work on exes that have resource edits?

LF2 requires ddraw.dll to display the graphics on-screen. At first, it'll search for the dll in the folder the exe is located in; if the dll is not there, it'll go to into the windows\system32\-folder. Basically, the patched ddraw.dll executes the AI-related stuff and then calls the original dll. This means that

Yes. I'm using it with an overly patched exe (resources + dll-framework + various hex-edits around the place) and it's working flawlessly
