What distinguishes a trigger collider from a normal collider?

A trigger collider is specifically designed to detect overlaps or intersections with other colliders without producing physical responses, such as bouncing or blocking movement. This capability allows trigger colliders to respond to events such as player entry into an area, item pickups, or zone transitions while enabling other objects to pass through them freely.

In contrast, normal colliders interact physically with objects, which means that when two normal colliders collide, they might bounce off each other or prevent one from passing through the other. This is crucial for gameplay mechanics that require solid interactions between objects, such as a player character running into a wall, but it differentiates normal colliders from trigger colliders, which are meant for detection rather than interaction.

The other options do not accurately characterize the functionality of trigger colliders. For instance, while it might be true that some colliders could cause damage or generate a score during interactions, this is not a defining feature of trigger colliders.
