Description: OnDrawGizmosSelected is a method in Unity used to draw gizmos in the scene only when the associated object is selected in the editor. Gizmos are visual elements that help developers visualize and better understand the arrangement and behavior of objects in the scene. This method is automatically invoked by the Unity engine, allowing programmers to customize the visual representation of their objects in the editor, which is useful for debugging and adjusting settings without needing to run the game. By using OnDrawGizmosSelected, developers can display relevant information, such as attack ranges, area effects, or any other data that facilitates understanding the object’s behavior. This method differs from OnDrawGizmos, which is called regardless of whether the object is selected or not, allowing for more specific control over when and how gizmos are drawn. In summary, OnDrawGizmosSelected is a powerful tool for enhancing the development experience in game development, providing a clear and visual way to interact with scene elements.
Uses: OnDrawGizmosSelected is primarily used in the development of video games and interactive applications in Unity. It allows developers to create visual representations of objects in the scene that are only visible when the object is selected, helping to keep the workspace clean and organized. This method is especially useful for displaying contextual information that may be relevant during design and debugging, such as collision boundaries, activation areas, or any other aspect that requires specific developer attention.
Examples: A practical example of OnDrawGizmosSelected is in a platformer game where an enemy has a detection range. By implementing this method, the developer can draw a circle around the enemy that is only shown when the object is selected, allowing for easy adjustments to the detection range without interfering with other scene elements. Another example could be a ‘trigger’ object that activates an event; the developer could use OnDrawGizmosSelected to visualize the activation area only when working on that specific object.
