hey guys.. i'm trying to make an entity get as close as possible to another entity without passing it, so i wrote this little script, but the moving entity just walks right past the stationary entity. I have no idea why... it's a logic error on my part, maybe someone knows why?

Code:

---

var destination[3];
var temp[3];
var OldDestDist[3]

		if(destination[0] !=0)
		{
			temp = abs(vec_dist(my.x,destination));
			if(temp < oldDestDist)
			{
				vec_set(oldDestDist,abs(vec_dist(my.x,destination)));
				my.move = 1;
			}
			else
			{
				my.move = 0;
				destination[0] = 0;
			}
		}

---

I don't think I need the abs(); but it was the same way either way so... any ideas people?

Try to do something like this:

var distance_to_target;
var max_move_speed = 10;
var move_distance;

distance_to_target = vec_dist(my.x,target.x);

if ( distance_to_target < max_move_speed )
move_distance = distance_to_target;
else
move_distance = max_move_speed;

If you now move your entity the distance of move_distance in the direction to target, it exactly stops at the position of target

I don't quite understand how your vectors are working. This line in particular
Code:

---

				vec_set(oldDestDist,abs(vec_dist(my.x,destination)));

---

should be an error. abs() will give you a number, the distance to the target, but then you're plugging that into vec_set. This will do something like
Code:

---

vec_set(oldDestDist, 50.000);

---

which would usually be a crash unless the distance happens to be a valid pointer.

You're also assigning a single number to an array in a few other places, although in C-Script this is valid as long as you realize you're assigning to the first element of the array only.

It seems like you need to make your var[3]s just vars.
