just want to ask what code should i put inside the while to trigger my if statement. when the gap between the 2 entities is less than 100. the other mdl should stop walking and perform an attack.




var gap = vec_dist(my.x, your.x);

while(1)
{

if(gap >= 100)
{
var distance =-3*time_step;
c_move(me, vector(0,distance,0), NULL, GLIDE);
my.ANIMATION += 2* distance;
ent_animate(my,"walk",my.ANIMATION,ANM_CYCLE);

if(gap < 100)
{
my.ANIMATION = 0;
my.ANIMATION += 25 * time_step;
ent_animate(my, "attack", my.ANIMATION,ANM_CYCLE);
}

}

wait(1);
}

You need to calculate the distance every frame, so it goes inside the while loop.

When I put the vec_dist(my.x,your.x) in the condition, the function crahses but the program still run.

The error is probably caused because either 'my' and/or 'your' is not set to a valid ENTITY*, so make sure 'my' and 'your' are both valid.

I think im gonna go crazy hehehe, i run the program and a message box that says "empty ponter in soldier_enemy" pops out. T,T. Better grab some coffee hhmm. . .

Listen to DJBMASTER and read his last post again (who is you? try you = player; ).

if you havent figured it out, the you doesnt point to anything.

if this function is going to be called by an enemy, you can do this:

//put up top
entity* player

//put in player action
player = me; //this defines the player entity

//change vec_dist to:
vec_dist(my.x, player.x);

if you dont want you to be the player, you could scan for it

scan will return the entities it hits

look up c_scan perhaps you could do:
scan_var = scan(.....);
if(scan_var > 0) { attack();} //if there is an entity near, attack
else
{
//walk
}

scan also saves the YOU pointer. so, it returns the distance of the entity AND saves the you pointer.

this is all theoretical, but it should work. hope it helps!
