OnGUI() Function in Unity - Unity Scripting API MonoBehaviour Tutorial 10

Описание

Notes for You:: OnGUI() Function in Unity - Unity Scripting API MonoBehaviour Tutorial 10
- is called many times per frame.
- is best for drawing GUI elements and handling GUI events.

Ex: Drawing a UI button, handling click event etc.

Note: For drawing UI elements and handling UI events, it is recommended to use new UI system with Canvas instead of OnGUI event method; because OnGUI is old way of creating UI for games; new UI system with Canvas is more easier, flexible, feature rich and development friendly.

Example code:

void OnGUI()
{
Debug.Log ("OnGUI");

bool isButtonClicked = GUI.Button (new Rect (0f, 0f, 100f, 30f), "Button");
if (isButtonClicked) {
Debug.Log ("isButtonClicked" + isButtonClicked);
}

}
