hello there. I need to make a simple ai which triggers an event when it is near a specific model or the player.

here is the code for the ai of the cars.



function viol_func()
{

......blah blah

}
action FollowPath()
{
my.emask |= ENABLE_IMPACT;
my.event = viol_func;

reset(my,PASSABLE);


var temp;

// attach entity to nearest path
result = path_scan(me,my.x,my.pan,vector(360,180,1000));
if (result == 0) { wait(-10);} // no path found



my.skill1 = 1 ; //start with first node
path_getnode(my,my.skill1,my.skill2,NULL);
while(1) {

// close to node => get position of next node
my.skill4 = my.z;
if(vec_dist(my.skill2,my.x) < 16) {
my.skill1 = path_nextnode(my,my.skill1, 1);
path_getnode(my,my.skill1,my.skill2,NULL);
}

// turn to next node
vec_diff(my.skill5,my.skill2,my.x);
vec_to_angle(my.skill8,my.skill5);

my.pan += clamp(ang(my.skill8-my.pan)*0.50,-5,5)*time_step;

c_move(me,vector(aispeed *time_step,0,0),nullvector,GLIDE | IGNORE_PASSABLE | IGNORE_YOU);




if (my.skill1 == 0)
{
wait(-3);
aispeed = 5;

result = path_scan(me,my.x,my.pan,vector(360,180,1000));
// attach entity to nearest path
if (result == 0) { aispeed = 0;} // no path found

temp = path_scannode(my, 1);

my.skill1 = temp ; //start with first node

path_getnode(my,my.skill1,my.skill2,NULL);

}

if (my.skill1 > 3)
{
aispeed = 15;

}

wait(1);
}

}

action CarInit()
{
player = me;


c_setminmax(my);
my.flags |= ZNEAR;

// build a car and wait til all wheels are ready
ChassisInit();
my.material = mat_metal;

while (wheelCounter<4) { wait(1); }


snd_stop(engine_wav);


UpdateSpeed(); // update rear wheel speed (continuous)
SpeedControl();// change speed (continuous)
SteerControl();// change heading (continuous)


}

the code above can trigger an event in impact but I need to make it work on range.

an example is when the ai car is near the player the ai car will slow down or horn the player.

btw I used the car physics sample...

thanks.
