SWGhost Saga

Stage 3 gives the ghost eyes. Two SWEyeball instances are now built and managed entirely inside the SWGhost class — the sketch only had to supply two color arrays. This stage also demonstrates three independent SWGhost instances side by side, each with its own body color, iris color, and toe count.

Eye Geometry

Eye size and spacing are derived from two randomly chosen factors stored in each ghost instance:

• Span factor (random(0.7, 0.95)) — controls how far the eyes spread across the head diameter. A value of 1.0 would push the outer edges to the head's rim.
• Gap factor (random(0.0, 0.10)) — controls the spacing between the eyes. From these two fractions the eye radius and center-to-center distance are derived exactly.
• Both factors are fixed for the lifetime of the ghost; every reload produces a slightly different look.

Interaction Priority

SWGhost.handleMousePressed() now checks the eyes before checking for a whole-ghost drag:

• Click a pupil → drag the pupil (independent of the ghost body).
• Click the ghost body (but not a pupil) → drag the entire ghost, eyes and all.
• Click outside → toggle the grid.

Pupil positions are preserved across ghost drags — pupils don't snap to center when you pick up the ghost.

Three Ghosts, Three Looks

The sketch constructs three SWGhost instances equally spaced across the canvas. Each ghost is independently draggable and has its own pupil-drag behavior:

• Ghost 1 (red) — 0 toes (flat bottom), blue iris
• Ghost 2 (green) — 1 toe, brown iris
• Ghost 3 (blue) — 2 toes, orange iris

All three share white sclerae, black pupils, and borders hidden (shouldShowStroke = false) for a clean, painterly look. The toe progression (0 → 1 → 2) demonstrates the full range of the flat-bottom feature introduced this stage; any value 0–8 is valid.

What Changed in the Sketch

Compared to Stage 2, the sketch gains:

• eyeColors and pupilColors arrays passed as the seventh and eighth arguments to new SWGhost()
• A GHOST_TOES array ([0, 1, 2]) and GHOST_BODY_COLOR_NAMES / GHOST_IRIS_COLOR_NAMES parallel arrays replacing the single color variables
• A construction loop that builds all three SWGhost instances into a ghosts[] array
• shouldShowStroke = false — borders hidden on all parts

Mouse handlers now loop over ghosts[]; everything else — draw loop, save image — is identical to Stage 2.

The Road Ahead

Stage 4 will add animation — floating, wobble, or patrol behavior using SWSinusoid. A future lookAt() method will let both eyes track a target position simultaneously.
