Return 2 FLOAT from 1 VOID
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; } }
