We have created a vertical and horizontal scroll view by using
GUI.BeginScrollView() to begin the scroll view and ended it with
GUI.EndScrollView() . Basically, we can use this function, which is very convenient
to use, when we want to create a scrollable area that contains any type of a GUI object, be-
cause this function will automatically create a scrollable area from the two Rect paramet-
ers that we set up.
For example, in order to create a vertical scroll area at position x : 0 , y : 0 , Width : 100
pixels, and Height : 40 pixels, which contains three buttons with each button having 40
pixels height, we'd use code similar to the following snippets:
// Unity JavaScript user:
var scrollPostion : Vector2 = Vector2.zero;
function OnGUI() {
scrollPostion = GUI.BeginScrollView(new Rect(0,0,100,40),
scrollPostion, new Rect(0,0,80,120));
GUI.Button(new Rect(0,0,80,40),"Button 1");
GUI.Button(new Rect(0,40,80,40),"Button 2");
GUI.Button(new Rect(0,80,80,40),"Button 3");
GUI.EndScrollView();
}
// C# user:
Vector2 scrollPostion = Vector2.zero;
void OnGUI() {
scrollPostion = GUI.BeginScrollView(new
Rect(0,0,100,40),scrollPostion, new Rect(0,0,80,120));
GUI.Button(new Rect(0,0,80,40),"Button 1");
GUI.Button(new Rect(0,40,80,40),"Button 2");
GUI.Button(new Rect(0,80,80,40),"Button 3");
GUI.EndScrollView();
}
