MoveTowards not working properly - unity3d

Question

I want to move toward each object from my array, I mean move first to [0] then [1] and so on. I'm having problems with animations.
function exit( path : Array){
var node : Node;
var go : GameObject;
for(var i=1 ; i < path.length ; i++){
node = path[i] as Node;
go = node.getContent() as GameObject;
nodeS.getContent().transform.position = Vector3.MoveTowards(nodeS.getContent().transform.position, go.transform.position ,1);
}
}
I call exit function inside Update(). As a result, I'm getting weird movements, and I understand that the problem is between for loop and Update function.

Answer 1

You get the weird movements, because in each Update() (each call of your exit()), you go over all of the nodes in the path and move just one step towards them. It's because Vector3.MoveTowards only calculates the next step of the movement from current to target. The size of your step is "1" (the third parameter of Vector3.MoveTowards())
So basically, in each Update(), this happens:
move 1 unit closer to the first node of path
move 1 unit closer to the second node of path
move 1 unit closer to the third node of path
and so on
So, I'd do it somehow like this:
function exit(path : Array) {
var node : Node;
var go : GameObject;
node = path[CurrentNodeIndex] as Node;
go : GameObject = node.getContent() as GameObject;
if (!Mathf.Approximately(
Vector3.Distance(nodeS.getContent().transform.position, go.transform.position),
0
)) {
nodeS.getContent().transform.position = Vector3.MoveTowards(nodeS.getContent().transform.position, go.transform.position, 1);
} else {
CurrentNodeIndex++;
Debug.Log("Starting to move towards next node: " + CurrentNodeIndex);
if (CurrentNodeIndex >= path.length) {
Debug.Log("The final node was reached!");
return;
}
}
}
What this does:
Get the first node from the path (CurrentNodeIndex is 1 at the beginning)
if the current distance between this node and nodeS (using Vector3.Distance) is not approximately 0 (using Mathf.Approximately), move one step closer to the node (using Vector3.MoveTowards)
this is called every Update until the distance between the two nodes is approximately 0. Then the CurrentNodeIndex is increased.
in next Update, select the next node from path and repeat the process - start moving towards it
when the last node from path was reached, just return. You can also have some global private bool flag indicating this and optimize
Please forgive any compilation errors; I don't use Unityscript, but C#, and have no means to test it right now.
BTW, is there any reason why you start taking notes from path with index 1 and not 0? If you meant to start with the actual first node of path, initialize CurrentNodeIndex to 0 instead of 1.
