在Unity3D c＃中每10秒更改一次相机颜色

Question

I want to change the camera colour in unity and I know how to change it once in the script camera.backgroundColor = Color.red;

But how to change it after every 10 sec interval, is there any timer like something which can be called after certain time.

Thank You

Answer 1

You can use timer,

Timer tm = new Timer(ChangeColor, cameraObject, 0, 1000);
    private void ChangeColor(object camera)
    {
        //camera is your camera object
        if (camera != null)
        {
            camera.backgroundColor = Color.red;
        }
    }

Also you can pass the color as parameter in ChangeColor method to set the desired color.

Timer tm = new Timer(ChangeColor, color, 0, 1000);
        private void ChangeColor(object color)
        {   
            Color backColor = color as Color;
            // camera is member variable
            if (color!= null)
            {
                camera.backgroundColor = backColor ;
            }
        }

or You can also pass the camera object and color both as Tuple.

Answer 2

You could use Timer , however I would solve it with a simple condition in your Update() method:

float elapsedTime;

void Update()
{
    elapsedTime += Time.deltaTime;

    if (elapsedTime >= 10)
    {
        elapsedTime -= 10;
        // insert logic for changing color below:
        camera.backgroundColor = Color.red;
    }
}

In my opinion, this is easier to use.
