A problem about Update function

Hello i hava a little problem about my code.

if (Sitution == "To Right")
{
Boomerang.transform.position += new Vector3(1, 0.5f, 0) * Time.deltaTime * Speed;
Boomerang.transform.Rotate(0, 0, -5 * Speed);
if (Input.GetMouseButton(0))
{
Sitution = "To Left";
}
}
if (Sitution == "To Left")
{

Boomerang.transform.position += new Vector3(-1, 0.5f, 0) * Time.deltaTime * Speed;
Boomerang.transform.Rotate(0, 0, 5 * Speed);
if (Input.GetMouseButton(0))
{
Sitution = "To Right";
}
}

This is my code. Code is doing if sitution is equal to "To right" boomerang going to right,if sitution is equal to "To left" boomerang going to left. If the player click to button, boomerang changing direction.

The problem is sometimes when i click to button boomerang direction is not changing. What is the problem?

 

I made something that works, there are better ways to do this however.

Code (CSharp):

1.  
2. // Check for input
3. if (Input.GetMouseButtonDown(0)) {
4.        if(Sitution == "To Right") {
5.             Sitution = "To Left";
6.        } else if(Sitution == "To Left") {
7.             Sitution = "To Right";
8.        }
9. }
10.  
11. // Apply speed and rotation depending on Sitution
12. if (Sitution == "To Right") {
13.        Boomerang.transform.position += new Vector3(1, 0.5f, 0) * Time.deltaTime * Speed;
14.        Boomerang.transform.Rotate(0, 0, -5 * Speed);
15. } else if (Sitution == "To Left") {
16.        Boomerang.transform.position += new Vector3(-1, 0.5f, 0) * Time.deltaTime * Speed;
17.        Boomerang.transform.Rotate(0, 0, 5 * Speed);
18. }

I moved the input out from the if-statements and changed GetMouseButton to GetMouseButtonDown to check for button presses instead of button holds. I also joined the two if-statements with an 'else' so it can only either go right or left.

 

Problem is fixed. Thanks you very much !!
