Making a first person

For making a first person feature, let's take an agile approach to development. This means (in part) that we'll start by defining our new feature, or story, with a set of requirements. Then, we'll incrementally build and test this feature, one requirement at a time, by iterating and refining our work as we go along. Experimentation is not only allowed, it's encouraged.

Note

Agile software development is a broad term for methodologies that encourage small incremental and iterative developments in a fashion that's easy to respond to the changing and refined requirements.

Feature: As a first-person character, when I start walking, I will move through the scene in the direction I am looking until I indicate to stop walking.

Here are the requirements to achieve this feature:

• Move in the direction you're looking

• Keep your feet on the ground

• Don't pass through solid objects

• Don't fall off the edge of the world

• Step over small objects and handle uneven terrain

• Start and stop moving...
