I have start lern AI coding and i have a question: what is wrong in this code (BOT DLL):

void TestGlobalAI::EnemyEnterLOS(int enemy)
{
	enemies.insert(enemy);
	enemypos = callback->GetAICallback()->GetUnitPos(enemy);
	enemyspoted = true;
	losid[enemy]=1;
}

void TestGlobalAI::EnemyLeaveLOS(int enemy)
{
	enemies.erase(enemy);
	losid[enemy]=0;
}

void TestGlobalAI::UnitDestroyed(int unit,int attacker)
{
	myUnits.erase(unit);
	
	
		const UnitDef *ud=callback->GetAICallback()->GetUnitDef(unit);
		if(losid[attacker]==1)
		{
				
				const UnitDef *ude=callback->GetAICallback()->GetUnitDef(attacker);
				
				Tbl[ud->id][ude->id]+=1;
				
				sprintf(g,"TBL[%i][%i]: %i",ud->id,ude->id,Tbl[ud->id][ude->id]);
				callback->GetAICallback()->SendTextMsg(g,0);
			
			
		}
		warunit[ud->id]+=1;
		sprintf(g,"warunit[%i]: %i",ud->id,warunit[ud->id]);
		callback->GetAICallback()->SendTextMsg(g,0);
	

	
	
	
}



void TestGlobalAI::EnemyEnterRadar(int enemy)
{
}

void TestGlobalAI::EnemyLeaveRadar(int enemy)
{

}

void TestGlobalAI::EnemyDamaged(int damaged,int attacker,float damage,float3 dir)
{
}

void TestGlobalAI::EnemyDestroyed(int enemy,int attacker)
{
	enemies.erase(enemy);
		const UnitDef *ud=callback->GetAICallback()->GetUnitDef(attacker);
		if(losid[enemy]==1)
		{
				losid[enemy]=0;
				
				const UnitDef *ude=callback->GetAICallback()->GetUnitDef(enemy);
				Tbl[ud->id][ude->id]-=1;
				
				sprintf(g,"TBL[%i][%i]: %i",ud->id,ude->id,Tbl[ud->id][ude->id]);
				callback->GetAICallback()->SendTextMsg(g,0);
			
			
		}
		warunit[ud->id]-=1;
		sprintf(g,"warunit[%i]: %i",ud->id,warunit[ud->id]);
		callback->GetAICallback()->SendTextMsg(g,0);
	
	

}

When i am testing this BOT, game crash

. I dont know why.

Can you give more information, such as how ti crashes, is it a debug build or a release build, and have you compiled spring using VS2005 or are you attempting to use the spring off of this site with the AI?

The game crashes during the battle and vs show me unhalted exception.
It's debug build(rts and AI).

before you continue, check the ai interface has not returned a null pointer for UnitDef*

Thx. How can i check it? Sorry for that stiupid question but i want be sure.

example

Code: Select all

if ( ud == NULL ) return; // not a valid pointer, return before using & segfaulting

Posted: **02 Jul 2008, 21:55**

thx but i use somethink like that :

Code: Select all

const UnitDef *ud=callback->GetAICallback()->GetUnitDef(attacker);
	if(ud!=0)
	{...}

and it works

.
Thank you AF.
