Change the Colour of UGUI button in script?
For the new UGUI button. I want to change the colour when the button has been pressed and then when a new button is pressed I want to be able to change the colour of new button and reset the old button's colour - kind of like a radio button. However I don't know how to access the UGUI button colour in script.
You need to add:
using UnityEngine.UI;
In the top of your script. Then you can access all the UI related classes.
public Button button;
public void Start()
{
button.colors.normalColor = new Color(0.22f, 0.22f, 0.22f, 1f);
}
Ok So Obviously I'm still missing something because I had all of my buttons listed as GameObjects since I couldn't add the listeners properly when they were Buttons. So this is what I have:
GameObject button;
button_1 = GameObject.Find ("button_1");
button_1.GetComponent().onClick.AddListener(delegate{selectRollNumber(1);});
button_1.GetComponent<Button>().colors.normalColor = new Color(0.22f, 0.22f, 0.22f, 1f);
And I get the error "Assets/Scripts/DieRollerScript.cs(165,49): error CS1612: Cannot modify a value type return value of `UnityEngine.UI.Selectable.colors'. Consider storing the value in a temporary variable"
I'm not sure what I'm doing wrong. I expect I've over complicated something.
use this:
Button button_1 for your variable.
button_1.gameObject.onClick ....
button_1.colors ...
I ended up using this: button_1.GetComponent().image.color = Color.red; Which works but I would still like to actually change the normal color in case I am ever need too.
This is what I did to change the color of the new UI images in 4.6 beta 17, hope it helps =)
using UnityEngine.UI;
public (name of script that holds the color variable lets say Image) Image image;
public Transform Button; (either drag the button onto this or use the Start function)
public Color color;
void Start()
{
Button = GameObject.Find("button");
}
void Update()
{
//If pressed == true then do the following:
image = Button.GetComponent<Image>();
color.r = 1; (put percent out of 1 for amount of red on button i.e. I want it all red)
color.g = 0.1f; (with a little bit of green, 10% green)
color.b = 0.1f; (and a little bit of blue, 10% blue)
color.a = 0.5f; (and the alpha at 50%)
image.color = color;
}
