Hide_Show_Panel Script

Panel must have CanvasGroup Component.

The following script can be put on any panel to control whether the panel is hidden when the scene starts. By default, any panel with this attached script will be hidden when the scene is initially loaded.

This script can be used on the DecisionPanel which controls buttons for changing scenes. A checkbox in the inspector provides an option to have the panel start in open state when the scene loads.

The Panel must have a CanvasGroup Component.

When working with SimpleDialog, or DialogManager, this DecisionPanel should be set as the Next Panel To Open in the SimpleDialog or DialogManager script.
