1. Inside the method we will check if the ball reaches the edges of the game field and change its speed values according to the accelerometer values. The
OnObjectUpdate
method gives you the object as a parameter.Method OnObjectUpdate:Int(obj:ftObject)
2. Perform a
SELECT
operation on theobj
variable:Select obj
3. If the object is equal to the object in
g.ball
, it is our ball:Case g.ball
4. Now, check whether the ball reaches the top or bottom edge and whether its y speed value indicates that it is moving towards the corresponding edge:
If (obj.yPos < obj.GetHeight()/2 And obj.GetSpeedY() < 0) Or (obj.yPos > (g.ch - obj.GetHeight()/2) And obj.GetSpeedY() > 0) Then
5. Reverse the
Y
speed factor so it will bounce off the edge. Also play the Hit sound effect:obj.SetSpeedY(-obj.GetSpeedY()) g.sndHit.Play() Endif
6. Next, check whether the ball reaches the left or right edge and whether its speed x value indicates that it is moving...
