PShape alien, head, body;
This is the correct code. I'll update the reference. Thank you for reporting.
void setup() { size(100, 100, P2D);
// Create the shape group alien = createShape(GROUP);
// Make two shapes head = createShape(ELLIPSE, 0, 25, 50, 50); head.setFill(color(255)); body = createShape(RECT, -25, 45, 50, 40); body.setFill(color(0));
// Add the two "child" shapes to the parent group alien.addChild(body); alien.addChild(head); }
void draw() { background(204); translate(50, 15); shape(alien); // Draw the group }
The 4 example on createShape() reference page is incorrect and does not work in processing 2.0b8
// Define the individual shapes and the group PShape alien, head, body;
void setup() { size(100, 100, P2D); alien = createShape(GROUP); // Make two shapes
head = createShape(ELLIPSE, 0, 0, 50, 50); head.noStroke(); body = createShape(RECT, 0, 45, 50, 40); body.fill(0); // Add the two "child" shapes to the parent group alien.addChild(body); alien.addChild(head); }
void draw() { translate(25, 10); shape(alien); // Draw the group }
