Color Palettes

Premature abstraction is not a good idea

Design with components and strategies in mind, though

CRGBArray<NUM_LEDS> leds

Game development patterns are a good fit

CRGBSet drawLeds

Be a good FastLED citizen

use the tools in the library

follow similar style and naming

non-blocking loops only

returns a pointer to an inactive actor

finds an inactive actor and puts it into play

want to update the behavior, physics, and rendering for actors

FastLED FixedVector of Actors

A window into another set of led data

separate methods for update behavior, physics, and rendering

for example, report position so that other actors can perceive them

CRGB draw buffer

Limited ability to perceive its environment

(uncertain if this belongs to the actor or the manager)

results in a steering force

decide how to move

Force Registry

integrate position

Sensor notes and examples from others

draw to Actor drawBuffer

apply effects and animations

render to CRGBSet drawLeds

An autonomous agent is an entity that makes its own choices about how to act in its environment, without any influence from a leader or global plan.

Discussion of interface design, worth reviewing

Much more heavyweight than needed but want to look at interfaces and strategy pattern

not yet implemented

For Arduino so very relevant

Concrete Input Types

motion, light, sound, range

remote sensor, other will-o hosts

initialize new actors from the pool if needed

make these functions as atomic as possible

rangefinder may apply a wind force

update global forces from inputs

The parameters to onNotify() are up to you. That’s why this is the Observer pattern and not the Observer “ready-made code you can paste into your game”. Typical parameters are the object that sent the notification and a generic “data” parameter you stuff other details into.

If you’re coding in a language with generics or templates, you’ll probably use them here, but it’s also fine to tailor them to your specific use case. Here, I’m just hardcoding it to take a game entity and an enum that describes what happened.

color and noise effects can benefit from being rendered at the maximum framerate (~120-130)

render global effects

fastled.show()

global fade for trails

this is no longer a blocking function call!
