Copying and Pasting cs Code

In cs, like in almost any computer programming language, reading data from a file can be tricky. You add extra lines of code to tell the computer what to do. Sometimes you can copy and paste these lines from other peoples’ code.

For example, you can follow the pattern in this listing:

     void Apply( Transform dummyTarget, Vector3 dummyCenter )
     {
         // Early out if we don't have a target
         if( !controller )
             return;

         Vector3 targetCenter = _target.position + centerOffset;
         Vector3 targetHead = _target.position + headOffset;

         // DebugDrawStuff();

         // Calculate the current & target rotation angles
         float originalTargetAngle = _target.eulerAngles.y;
         float currentAngle = cameraTransform.eulerAngles.y;

         // Adjust real target angle when camera is locked
         float targetAngle = originalTargetAngle;

         // When pressing Fire2 (alt) the camera will snap to the target direction real quick.
         // It will stop snapping when it reaches the target
         if( Input.GetButton( "Fire2" ) )
             snap = true;

         if( snap )
         {
             // We are close to the target, so we can stop snapping now!
             if( AngleDistance( currentAngle, originalTargetAngle ) < 3.0f )
                 snap = false;

             currentAngle = Mathf.SmoothDampAngle( currentAngle, targetAngle, ref angleVelocity, snapSmoothLag, snapMaxSpeed );
         }
         // Normal camera motion
         else
         {
             if( controller.GetLockCameraTimer() < lockCameraTimeout )
             {
                 targetAngle = currentAngle;
             }

             // Lock the camera when moving backwards!
             // * It is really confusing to do 180 degree spins when turning around.
             if( AngleDistance( currentAngle, targetAngle ) > 160 && controller.IsMovingBackwards() )
                 targetAngle += 180;

             currentAngle = Mathf.SmoothDampAngle( currentAngle, targetAngle, ref angleVelocity, angularSmoothLag, angularMaxSpeed );
         }

         // When jumping don't move camera upwards but only down!
         if( controller.IsJumping() )
         {
             // We'd be moving the camera upwards, do that only if it's really high
             float newTargetHeight = targetCenter.y + height;
             if( newTargetHeight < targetHeight || newTargetHeight - targetHeight > 5 )
                 targetHeight = targetCenter.y + height;
         }
         // When walking always update the target height
         else
         {
             targetHeight = targetCenter.y + height;
         }

         // Damp the height
         float currentHeight = cameraTransform.position.y;
         currentHeight = Mathf.SmoothDamp( currentHeight, targetHeight, ref heightVelocity, heightSmoothLag );

         // Convert the angle into a rotation, by which we then reposition the camera
         Quaternion currentRotation = Quaternion.Euler( 0, currentAngle, 0 );

         // Set the position of the camera on the x-z plane to:
         // distance meters behind the target
         cameraTransform.position = targetCenter;
         cameraTransform.position += currentRotation * Vector3.back * distance;

         // Set the height of the camera
         cameraTransform.position = new Vector3( cameraTransform.position.x, currentHeight, cameraTransform.position.z );

         // Always look at the target
         SetUpRotation( targetCenter, targetHead );
     }
