I am puzzling around with this for quite a while now.

My AI should target the nearest suitable enemy.
The ENTITY of it's enemy is locally stored in the definition "my.enemy".

Code:

function find_enemy()
{
	for(you=ent_next(NULL); you!=NULL; you=ent_next(you))
	{
		if ((you != my) && (you.team != my.team) && (you.health>0))// go through all models with the correct specs
		{
//somehow determine the nearest suitable enemy
			my.enemy = you;//
		}
//////////
//somehow repeat the function, so that the AI can find new targets, if one happens to die or if another is closer.
	}
}

Including "my.enemy = NULL;" is what I was missing.

This code works perfectly smoothly

Code:

function find_enemy()
{
	my.enemy = NULL;
	//////////
	ENTITY* Entenemy;
	var next_target;
	//////////
	for(you=ent_next(NULL); you!=NULL; you=ent_next(you))
	{
		if ((you != my) && (you.team != my.team) && (you.health>0))
		{
			if(my.enemy == NULL)
			{  
				my.enemy = you;
				Entenemy = my.enemy;
				next_target = vec_dist(my.x, you.x);
			}
			else
			{
				if(vec_dist(my.x, you.x) < next_target)
				{
					my.enemy = you;
					Entenemy= my.enemy;
					next_target = vec_dist(my.x, you.x);
				}
			}
		}
	}
}

Thank you!
