Return 2 FLOAT from 1 VOID

Question

hi, i have to make a button on the new UI of unity, to semplify my work i want to set 2 float directly from the buttons in the editor. usually i use something like this:

 public float ExampleToSet;
 
 public void Example (float ExampleFloat)
 {
  ExampleToSet = ExampleFloat;
 }

and i set ExampleFloat from a field in the editor, but if i try to wrote something like this:

     public float ExampleToSet;
     
     public void Example (float ExampleFloat1, float ExampleFloat2)
     {
      ExampleToSet = ExampleFloat1 + ExampleFloat2;
     }

in the button editor [on click()] i can't set Example as a function.

any help? thanks in advance

You are talking about passing parameters, not return types.

Add the desired function as a Listener via script. Only one parameter is possible, but you can circumvent this by using a custom class instance as the parameter, which in turn may contain as many variables as you wish.

  public Button button;
     public float float1;
     public float float2;
     public float exampleToSet;
 
     void Start() {
          ButtonParameter buttonParameter = new ButtonParameter (float1, float2);
          button.onClick.AddListener(delegate { Example (buttonParameter ); });
     
     }
     
     public void Example (ButtonParameter buttonParameter ) {
            exampleToSet = buttonParameter.exampleFloat1 + buttonParameter.exampleFloat2;
      }
     
     [System.Serializable]
     public class ButtonParameter {
          public float exampleFloat1;
          public float exampleFloat2;
     
          public ButtonParameter() {}
           public ButtonParameter(float f1, float f2) {
              exampleFloat1 = f1;
              exampleFloat2 = f2;
          }
     
     }
