Main loop structure

Subroutines

• Time passing

Aging Hunger increasing Mood changing

• Logic and branching

Pet evolves Pet dies Gets sick

• Display

Idle animation, status, etc.

• Input

Feed Play Heal

Event timing

Use time counters.

Every N cycles or ticks, age increases or hunger changes.

Structuring view as a mode

VIEW MODE="IDLE"
IF NEEDS ATTENTION THEN VIEW MODE="CRY"
IF USER SELECTS FEED THEN VIEW MODE = "EAT"

Dislay subroutine renders based on VIEW MODE. Detaches display from behaviour.
