How can i change the gameobject color based on RGBA

Thank you @robertbu

In program$$anonymous$$g, how can i make the the 1.000 in different varable that the code become:

 String color = RGBA(1.000, 1.000, 1.000, 1.000) 
 _red = 
 _green =
 _blue =
 _a =
 
 GameObject.Find("Cube").transform.renderer.materials[0].color = new Color(_red,_green,_blue,_a);

Ahhh this is a string split and conversion problem. I did not understand that from your initial question. I tend not to answer these kinds of questions. Since I don't do much of them, my answers are brute force. There are many on this list that have very elegant solutions to these problem. So here is a brute force solution, but if you wait around for more answers, it is likely someone will give you a more elegant solution:

 function Start() {
     var colorString : String = "RGBA(1.000, 1.000, 1.000, 1.000)";
 
     var start = colorString.IndexOf("(");
     var length   = colorString.IndexOf(")") - start - 2;
     var s = colorString.Substring(start+1, length);
      
     var nums : String[] = s.Split(","[0]);
 
     var _red : float;
     var _green : float;
     var _blue : float;
     var _a : float;
 
     float.TryParse(nums[0], _red);
     float.TryParse(nums[1], _green);
     float.TryParse(nums[2], _blue);
     float.TryParse(nums[3], _a);
     
     Debug.Log(_red+","+_green+","+_blue+","+_a);
 }

Note I'm still confused by your question. How do you get a string color value from a game object. Is RGBA() a class I'm unaware of or something else? If this is a Unity color, you should be able to access a Color class value on that game object.

Thank you, i will try the solution ASAP,. however, is it similar to C#?

btw, the RGBA(1.000, 1.000, 1.000, 1.000) String value is get by

 itm.color = body.transform.renderer.materials[0].color.ToString();

i store RGBA(1.000, 1.000, 1.000, 1.000) in the X$$anonymous$$L string value, also , i need to load and read this value to set it into new gameobject. So, i need to change RGBA(1.000, 1.000, 1.000, 1.000)

Ahhhh, now everything makes sense. Here is the C# translation of the above code:

 void Start() {
         string colorString = "RGBA(1.000, 1.000, 1.000, 1.000)";
         
         int start = colorString.IndexOf("(");
         int length   = colorString.IndexOf(")") - start - 2;
         string s = colorString.Substring(start+1, length);
         
         string[] nums  = s.Split(","[0]);
         
         float _red, _green, _blue, _a;
         
         float.TryParse(nums[0], out _red);
         float.TryParse(nums[1], out _green);
         float.TryParse(nums[2], out _blue);
         float.TryParse(nums[3], out _a);
         
         Debug.Log(_red+","+_green+","+_blue+","+_a);
 }

Thank you :> i will try it ASAP, because i have some problem for get the value form X$$anonymous$$L, i will try this after i can get the X$$anonymous$$L value.
