Unity GUILayout Scrollbar is an important feature of the Unity game engine. It enables developers to create horizontally or vertically scrollable content in their games. The Unity GUILayout scrollbar provides developers with the tools they need to create a polished GUI that can easily be interacted with by players.
When using GUILayout scrollbars, however, developers may find that it disappears after interaction with other GUI elements. In this article, we will discuss how to make GUILayout scrollbars stay visible.
Creating the Scrollbar
The first step to making a Unity GUILayout scrollbar stay visible is to create it within the GUI. Here are the steps to do this:
Create a Rect (Rectangle) object by dragging it from the Hierarchy panel onto the Scene panel.
Resize it to the size of the area you would like your scrollable content to appear.
Create a GUISkin for the scrollbar.
Set the GUISkin to be the “Scrollbar” in the Hierarchy panel.
Add a GUILayout.BeginScrollView () to the code.
Add a GUILayout.EndScrollView () to the code.
Once these steps are completed, you should see the scrollbar in the scene.
Keeping the Scrollbar Visible
Now that you have the scrollbar in place, you need to make sure that it remains visible even when clicking on other GUI elements. To do this, you should add code that checks for a click before hiding the scrollbar.
Create a Boolean variable and set it to “false”.
Add an “if statement” in the update loop of your game.
If the Boolean is set to “true”, then set the scrollbar to not visible.
- If the Boolean is set to “false”, then set the scrollbar to be visible when the mouse is clicked.
By adding this code, the scrollbar will remain visible when clicking other GUI elements, since it will only be hidden when the Boolean is set to true.
