Well , just a small question

I am currently experimenting POD 2.6 src , I am curious why sometimes the bot wont shoot ? Perhaps some pod l33t could help me ...

[NEW]
I am frustated of getting this buffer overrun error ...

Code:

Buffer overrun detected

 

D:\valve\hl.exe

 

A buffer overrun has been detected which has corrupted the program's internal state. The program cannot safely continue execution and must now be terminated

WTH ??!

Re: Well , just a small question

one bad pointer crash i know of could help (very common crash bug)

Code:

 // Enemy behind Obstacle ? Bot wants to fire ?

         if (pBot->iStates & STATE_SUSPECTENEMY && pBot->bWantsToFire)

         {

                 int iTask = pBot->pTasks->iTask;

                 // Don't allow shooting through walls when camping 

                 if(iTask == TASK_PAUSE || iTask == TASK_CAMP)

                         pBot->bWantsToFire = FALSE;

         }

should be

Code:

 // Enemy behind Obstacle ? Bot wants to fire ?

         if (pBot->iStates & STATE_SUSPECTENEMY && pBot->bWantsToFire)

         {

                 int iTask = BotGetSafeTask (pBot)->iTask;

                 // Don't allow shooting through walls when camping 

                 if(iTask == TASK_PAUSE || iTask == TASK_CAMP)

                         pBot->bWantsToFire = FALSE;

         }

Re: Well , just a small question

"buffer overrun" means this:

PHP Code:


		
			
#include <string.h>

main()

{

   char sz[5];

   strcpy(sz, "abcdefghijklmnopqrstuvwxyz"); // buffer overrun

}

Re: Well , just a small question

I fail to see how A* is related to shooting...

Re: Well , just a small question

when having wrong pointers somewhere, you might often get error in nonrelated code ...

Re: Well , just a small question

I wont to ask question to.
Is this thinks are same

Code:

int iTask = pBot->pTasks->iTask;

Re: Well , just a small question

this

Code:

int iTask = pBot->pTasks->iTask;

returns a pointer to the iTask element in the structure pointed to by pTasks. But this code will crash if pTasks is NULL, i.e. points to no tasks structure. This however

Code:

int iTask = BotGetSafeTask (pBot)->iTask;

will always return a valid pTasks pointer (even if it points to an empty task structure, what I'd call a "failsafe pointer"). This way iTask is always guaranteed to be accessible and the code won't crash.
