How to make 2D-buttons right
I'm doing buttons for my 2d-game making sprites with OnMouse-events. I've decided to use animator component and switching states (normal, mouse over, pressed) with it like this:
void OnMouseEnter()
{
GetComponent<Animator> ().Play ("Over");
}
void OnMouseExit()
{
GetComponent<Animator> ().Play ("Idle");
}
void OnMouseDown()
{
GetComponent<Animator> ().Play ("Pressed");
}
void OnMouseUpAsButton()
{
GetComponent<Animator> ().Play ("Over");
//do something here
}
The other way is to load every state in a sprite object and assign to sprite renderer's .sprite the needed one or something like this, I don't remember details, but did this way too and it worked ok.
The question is: which way is better and why? Are there any other ways to make buttons?

I've decided to make it the easy way. Hope it will not brings me any trouble.
public Sprite normal;
public Sprite onEnter;
public Sprite onPressed;
void OnMouseEnter()
{
GetComponent<SpriteRenderer> ().sprite = onEnter;
}
void OnMouseExit()
{
GetComponent<SpriteRenderer> ().sprite = normal;
}
void OnMouseDown()
{
GetComponent<SpriteRenderer> ().sprite = onPressed;
}
public virtual void OnMouseUpAsButton()
{
GetComponent<SpriteRenderer> ().sprite = normal;
}
But you can face this problem: http://answers.unity3d.com/questions/748101/sprite-button-being-pressed-when-not-even-pointed.html Hope it will be solved in Unity 4.6.
