How do i use it? It wont let me create an instance of it since its an abstract class, so what steps do i need to take to use any of the cheats for an AI?

Look at the global AI header files...

Right, thanks its working, but im getting this error:

Code: Select all

.\GlobalAI.cpp(143) : error C2664: 'int IAICheats::GetEnemyUnits(int *)' : cannot convert parameter 1 from 'std::set<_Kty>' to 'int *'
        with
        [
            _Kty=int
        ]
        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

is this not right:

Code: Select all

	int* enemies = new int [5000];
	for(int i = 0; i < 5000; i++)
		enemies[i]=0;
	int numofenemies = cheat->GetEnemyUnits(enemies);

(where cheat = callback->GetCheatInterface();)

valgrind

Code: Select all

cheat = callback->GetCheatInterface();
if(cheat != 0){
   int* enemies = new int [5000]; 
   int numofenemies = cheat->GetEnemyUnits(enemies);
   if(numofenemies > 0){
      // ..... code here
   }
}

You missed out several checks, also whya re you setting all the array items to zero? You dotn need to, the function sets the values of the ones you need for you, and you're only gonna deal with numofenemies number of items. Cheats could also be zero/null pointer if the suer didnt type .cheats
Also I'd check that you havent defiend something such as set<int> enemies; somewhere else in the code. Try using something that isnt as generic as enemies anyways.

I have all the checks in place already, it was just the set<int>enemies...
Thanks

This error would seem to indicate that you are doing:

Code: Select all

set<int> enemies;
cheat->GetEnemyUnits(enemies);

Which is not syntactically equivilant.

AF's code sould work for what you're doing.

hmm, I dont wanna create another thread but here I go

Code: Select all

try{
   G->Update();
}catch(){
    G->L->Eprint("Exception calling G->Update!");
}

That works fine for me, but I want instead to have

Code: Select all

G->Update();

void Global::Update(){
   try{
        A->Update
   }catch(){
      eprint("error in A");
   }
   try{
      F->Update();
   }catch(){
      eprint("error in R");
   }
}

The problem here is that when an exception occurs when G->Update is called, the game still crashes for some reason. I end up having to put G->Update as a whole in a try catch block in the CGlobalAI, which means if something happens in R->Update I dont get the emssage "error in R->Update" I get the message "error calling G->Update" because I've nested try and catch blocks inside eachother.

How do i get back to just puttign the individual agents in the global class in their own try blocks without it crashing when an exception occurs....

I did pretty much exactly that (but changing the name of the int array to avoid conflicts), and although it compiles just fine, i keep getting an AI exception whenever this line is run (it isnt run if cheats are off)

Code: Select all

int numofenemies = cheat->GetEnemyUnits(enemies);

It doesnt seem different to the code used by other AIs so whats the problem? do i have to declare special classes or something?

The big Z indicated that you might need to allocate 10000, not 5000 into the int array.

Do you have the callback trace that your code generates? Is it and access violation, or an assertion error or?

Posted: **20 Dec 2005, 20:07**

He shouldnt get any errors witht hat code unelss there are 5000 or more untis ingame that arent allied to you.

Have you tried the same code but using the ordinary itnerface?

If all else fails and you have to ahve ti in there btu it's nto reliable put a try block around it

Posted: **21 Dec 2005, 00:51**

It works with the ordinary interface and a try block simply tells me what i already know, that the cheat interface seems fucked up...
Ill give it a full check tomorrow, try doing it in all different ways, etc... has ANYONE ever tried using it?

No, ppl actually try to develop a decent ai before trying to put an ai to cheat.
