Move 2d cube the opposite way of path when boolean is triggered

Hello,

I have a cube in 2d and I attached to it a script so that it can follow a path.

Everything is fine and the cube is moving properly in the path.

I have a boolean which checks the direction of the cube (normal direction or reverse)

The problem is that if I trigger the boolean the cube is not changing the direction immediately.

Instead it starts moving when it reaches the next waypoint.

Here is the code:

Code (CSharp):

1. [SerializeField]
2.     Transform[] waypoints;
3.  
4.     [SerializeField]
5.     float moveSpeed = 2f;
6.  
7.     [SerializeField]
8.     int waypointIndex = 0;
9.  
10.     [SerializeField]
11.     bool normal;
12.  
13.     private void Update()
14.     {
15.         Move();
16.     }
17.  
18.     void Move()
19.     {
20.         if(normal)
21.         {
22.             transform.position = Vector2.MoveTowards(transform.position,waypoints[waypointIndex].transform.position,moveSpeed * Time.deltaTime);
23.  
24.             if(transform.position == waypoints[waypointIndex].transform.position)
25.             {
26.                 if(normal)
27.                 {
28.                     waypointIndex += 1;
29.                 }
30.                  
31.             }
32.  
33.             if(waypointIndex == waypoints.Length)
34.             {
35.                 waypointIndex = 0;
36.             }
37.         }
38.  
39.         else
40.         {
41.             transform.position = Vector2.MoveTowards(transform.position,waypoints[waypointIndex].transform.position,moveSpeed * Time.deltaTime);
42.          
43.             if(transform.position == waypoints[waypointIndex].transform.position)
44.             {
45.                waypointIndex -= 1;
46.             }
47.  
48.             if(waypointIndex == -1)
49.             {
50.                 waypointIndex = waypoints.Length-1;
51.             }
52.          
53.         }
54.     }

Hi @subzer0

"Instead it starts moving when it reaches the next waypoint."

Is this code written by you or did you follow some tutorial or something like that?

I think if you read the code yourself line by line carefully, you'll see what/where the problem is.

Where/when does a condition in your code allow to change the waypointIndex?

 

@eses
I know. It is changing when the position of the cube is equal to position of the waypoint.

I want it to move immediately after I change the boolean.

The code is from a tutorial on youtube but I edited the code a bit.
