What does the OnTriggerEnter method detect in Unity?

The OnTriggerEnter method is specifically designed to detect when a collider enters a trigger collider in Unity. This method is part of the physics system and is used in scenarios where interactions between different game objects need to be monitored without causing physical collisions. For example, it can be utilized to detect whether a player has entered a designated area, such as a power-up zone, an enemy's detection range, or other game mechanics that require the recognition of overlaps between colliders marked as triggers. The OnTriggerEnter method operates when an object that has a collider enters another collider that is configured as a trigger, allowing for a variety of gameplay interactions and events to occur seamlessly within the game environment.
