Cannot Implicitly Convert Type in XNA

Question

i have a bouncing ball, and i tried to make so when it bounces once, the speed gets higher.

In my ball class, i have a float speed;

and i initialize

Answer 1

Perhaps speed is declared as type float.

You can do the math by converting speed from float to integer like this:

public void BallMovement()
{
    int speedInt = Convert.Int32(speed);

    if (movingUp) { ballRect.Y -= speedInt; }
    if (!movingUp) {  ballRect.Y += speedInt; }
    if (movingLeft) {  ballRect.X -= speedInt; }
    if (!movingLeft) {  ballRect.X += speedInt; }

    if (ballPosition.Y < 85)
    {
        movingUp = false;
    }
    if (ballPosition.Y >= 480)
    {
        movingUp = true;
    }
    ....

On the other hand, if you want the compiler to convert it for you (multiple times), you could cast each of the occasions where you reference speed with (int)speed.
