Time for action – creating a vector from cursor movement

Our cannonballs are propelled by an initial force that we create using the X and Y elements of the AddForce vector. Up until this point, the two values were set at a constant value of 12.5, creating the same velocity and angle each time.

In this section, we'll use the change in the X and Y values from our cursor to affect the dynamic X and Y values in our firing function so that the velocity and angle are affected by the way the cursor is moved. Perform the following steps to create the vector:

1. Declare two new float variables called mouseX and mouseY next to the other variables in your CannonScript.cs file as shown:

   private int buttonWidth;
   private int buttonHeight;
   private string buttonText;
   public GameObject cannonballPrefab;
   
   private float mouseX;
   private float mouseY;

2. Create a new function called CaptureTouch in CannonScript.cs using the following code:

   void CaptureTouch()
   {
   
   }
