Vector3 Position X animation

Guest User

I want to make my vector go right till it hits 300 X and then come back to the point where it started smoothly.
The code I have makes my vector to go smoothly to the right but I cant figure it out why its not going back....

Here is the code :)

public override void Update(ref GameTime pGameTime)

{

Vector3 tokenPosition = this.PossessedToken.Position;

tokenPosition.X = tokenPosition.X + 1;

this.PossessedToken.Position = tokenPosition;

if (tokenPosition.X > 300)

{

Vector3 tokenPosition1 = this.PossessedToken.Position;

tokenPosition1.X = tokenPosition1.X - 1;

this.PossessedToken.Position = tokenPosition1;

}

Try the following:

private int startPosition = -1;
private bool isForward = true;

public override void Update(ref GameTime pGameTime)
{
Vector3 tokenPosition = this.PossessedToken.Position;
if (startPosition == -1) startPosition = tokenPosition.X;

if(isForward && tokenPosition.X == 300)
{
tokenPosition.X = tokenPosition.X - 1;
isForward = false;
}
else if (isForward)
{
tokenPosition.X = tokenPosition.X + 1;
}
else if (tokenPosition.X == startPosition)
{
tokenPosition.X = tokenPosition.X + 1;
isForward = true;
}
else
{
tokenPosition.X = tokenPosition.X - 1;
}

this.PossessedToken.Position = tokenPosition;
}
