Opening the outpost

In this section, we will look at the two differing approaches for triggering the animation giving you an overview of the two techniques that will both become useful in many other game development situations. In the first approach, we'll use collision — detection a crucial concept to get to grips with as you begin to work on games in Unity. In the second approach, we'll implement a simple ray cast forward from the player.

Approach 1—Collision detection

To begin writing the script that will trigger the door-opening animation and thereby grant access to the outpost, we need to consider which object to write a script for.

In game development, it is often more efficient to write a single script for an object that will interact with many other objects, rather than writing many individual scripts that check for a single object. With this in mind, when writing scripts for a game such as this, we will write a script to be applied to the player character in order to check for...
