How can a programmer resolve an issue where enemy missiles bounce off colliders instead of damaging the ship?

The issue where enemy missiles bounce off colliders instead of causing damage to the ship often relates to how the colliders interact with each other within the physics system. The correct approach to resolve this is by ensuring that the collisions are set up correctly, which includes managing the layers and collision interactions.

By turning off collisions between the UI ship layer and the missile layer, you can clarify the intended interactions. In Unity, different layers can be set to ignore collisions with each other; if the ship is on a layer that inadvertently ignores collisions with missiles, they will not register as collisions. This can lead to the appearance that missiles are bouncing off, rather than impacting and inflicting damage.

In contrast, the other options might not address the core issue effectively. For example, adjusting collider sizes may change collision detection but doesn't inherently resolve how the layers are interacting. Changing the ship layer rather than focusing on the interaction can lead to confusion in collision dynamics or may require additional adjustments. Lastly, adjusting the collider properties of the missiles could help but won’t guarantee that the missed collisions are related to the ship’s current layer settings and collision rules. By managing these interactions properly, you can ensure that missiles are recognized as colliding entities, allowing them to damage the ship as intended
