Unity 在运行时更改 UI 图像颜色

Question

public void ChaGradient(int tid)
{
    go.GetComponent<RawImage>().color = color[tid];
}

I attached this script to a the Camera object and made it be called on a OnClick() Button event with the the goal to change the Background color depending on what Button is pressed. Problem is that the when the Button is pressed the whole background just turns grey as if the Background object just disappeared.

Answer 1

I figured it out myself and its a classic oopsie. So when changing a color in the inspector it starts of with having an alpha of 0. So when you change the color on the color picker it does not change the alpha value, which is why it was invisible.
