Why would a developer choose to use a trigger collider instead of a normal collider?

Using a trigger collider allows a developer to manage game events without having to deal with the physical interactions that come with normal colliders. Trigger colliders are designed to detect when other colliders enter, exit, or stay within their boundaries, which can be essential for implementing game mechanics such as triggering events, activating abilities, or starting cutscenes when a player approaches a certain area.

This functionality is highly beneficial in scenarios where feedback is needed without impacting the physics simulation, such as when a player enters a designated zone to collect items or when enemies are detected. Unlike normal colliders that respond with physical forces, trigger colliders offer a streamlined approach to event handling, making them an ideal choice when the focus is on event management rather than physical collisions or gameplay hindrances.
