Can I right a generic method for components having same member variable?
Hello,
I am trying to write a static enumeration function that makes transparent components that having color member variable. While I know how to write a generic function, I couldn't figure it out how to change color variable of T type object.
Here is my three fade method for image, rawimage, and text components. So basically I want to make these functions into one with a generic method.
public static IEnumerator<float> _fadeInfadeOut(GameObject rawImage, float speed)
{
RawImage r = rawImage.GetComponent<RawImage>();
Color textureColor = r.color;
float a = textureColor.a;
if (a == 0)
{
while (a < 1)
{
a += Time.deltaTime * speed;
textureColor.a = a;
r.color = textureColor;
yield return 0;
}
textureColor.a = 1;
r.color = textureColor;
} else
{
while (a > 0)
{
a -= Time.deltaTime * speed;
textureColor.a = a;
r.color = textureColor;
yield return 0;
}
textureColor.a = 0;
r.color = textureColor;
}
}
public static IEnumerator<float> _fadeInfadeOutImage(GameObject image, float speed)
{
Image i = image.GetComponent<Image>();
Color textureColor = i.color;
float a = textureColor.a;
if (a == 0)
{
while (a < 1)
{
a += Time.deltaTime * speed;
textureColor.a = a;
i.color = textureColor;
yield return 0;
}
textureColor.a = 1;
i.color = textureColor;
}
else
{
while (a > 0)
{
a -= Time.deltaTime * speed;
textureColor.a = a;
i.color = textureColor;
yield return 0;
}
textureColor.a = 0;
i.color = textureColor;
}
}
public static IEnumerator<float> _fadeInfadeOutText(GameObject text, float speed)
{
Text t = text.GetComponent<Text>();
Color textureColor = t.color;
float a = textureColor.a;
if (a == 0)
{
while (a < 1)
{
a += Time.deltaTime * speed;
textureColor.a = a;
t.color = textureColor;
yield return 0;
}
textureColor.a = 1;
t.color = textureColor;
}
else
{
while (a > 0)
{
a -= Time.deltaTime * speed;
textureColor.a = a;
t.color = textureColor;
yield return 0;
}
textureColor.a = 0;
t.color = textureColor;
}
}
@umurcg If you have a look at each of those types in Visual Studio, they all inherit MaskableGraphic, so that's the type you can filter on for the generic. Also, I don't think your IEnumerator requires a generic type, since you're always returning zero. The following ought to do:
public static IEnumerator<T> _fadeInfadeOut(GameObject obj, float speed) where T: MaskableGraphic
{
T t = obj.GetComponent<T>();
Color textureColor = t.color;
float a = textureColor.a
if (a == 0)
{
while (a < 1)
{
a += Time.deltaTime * speed;
textureColor.a = a;
t.color = textureColor;
yield return null;
}
textureColor.a = 1;
t.color = textureColor;
}
else
{
while (a > 0)
{
a -= Time.deltaTime * speed;
textureColor.a = a;
t.color = textureColor;
yield return null;
}
textureColor.a = 0;
t.color = textureColor;
}
}
If you do need to do something with the zero you return, you can add a second generic type parameter, as I'm sure you're aware.
I am using more efficient coroutine plug in which forces me to return 0. But I can use normal coroutine for that method. Thanks.
