Can’t change GameObject color via script?

by

Here is your problem:

new Color(0f, 0f, 0f, **255f**);

The Color constructor parameter takes values from 0f to 1f but you are passing 0f to 255f range value to it.

That should be:

colorToFadeTo = new Color(0f, 0f, 0f, 1f);

If you want to use the 0 to 255 range then you must divide it by 255.

colorToFadeTo = new Color(0f, 0f, 0f, 255f/255f);

Also, there is Color32 which can take values between 0 and 255. You can use that then covert it back to color.

Color32 color32 = new Color32(0f, 0f, 0f, 255f));
Color color = color32;
