iTween Scale up then down again

I think your solution is to use iTween.ScaleTo(). When you ScaleBy() the expected behavior is exactly what you are describing, the button will scale up +5 OnMouseEnter and them -5 OnMouseExit, if there is a transformation occurring during a new mouse event the ScaleBy will Add ou Subtract the value from the current scale which is in middle of a transformation.

When you use ScaleTo no matter the current scale it will scale to the desired size.

I know it's a veeeeeery old question but I couldn't resist to comment on this.

The problem here is simple math, just follow me:

If you scale 100 up 5% you'll get this: 100 * 1.05 = 105

If you scale the result down 5% you'll get this: 105 * 0.95 = 99.75

Can you see? When you're working with percentages you can't just add and subtract the same % and expect it to come back to where it was.

So what you actually need is to scale down so it goes back to the original value. What you'll need is the following:

  onMouseEnter: iTween.ScaleBy(gameObject, iTween.Hash("x", 1.05, "z", 1.05, "default", .1));
  onMouseExit: iTween.ScaleBy(gameObject, iTween.Hash("x", 95.2380f, "z", 95.2380f, "default", .1));

And you might still get accumulative error, but I guess this time it won't be visible.

I'm sorry to revive this thread but for the sake of others who also encounter this (like me) up to this date, the probably easiest method is as @Paulo-Henrique025 answered. Just use iTween.ScaleTo instead of ScaleBy. This solved mine as it scales up / down nearly the desired Vector 3 values.

Make sure to have it like this:

Vector3 desiredSize = new Vector3 (desired_x,desired_y,desired_z);
float t = 1f;

iTween.ScaleTo(gameobject, desiredSize, t);

just replace the values you needed..
