Creates a new group and assigns it to the variable specified.
Groups are collections of sprites with similar behavior. For example a group may contain all the sprites in the background or all the "enemy" sprites. Instead of maintaining the images, animations, and properties (such as position, movement, and collisions) on each individual sprite, you can manage them on the group. A sprite can be in multiple groups and deleting a group doesn't affect the sprites themselves.

// Swarm of bees following the mouse. var group = createGroup(); for (var i = 0; i < 100; i++) { group.add(createSprite(randomNumber(150, 250), randomNumber(150, 250), 2, 2)); } group.setAnimationEach("bee_1"); group.setScaleEach(0.5); group.setRotateToDirectionEach(true); function draw() { background("white"); drawSprites(); var direction=(180*Math.atan2(World.mouseY-200, World.mouseX-200))/Math.PI; group.setSpeedAndDirectionEach(10, direction); }

// Stay cool! Keep all the bad vibes from getting you down. // Uses createGroup to make a bunch of bouncing baddies, // createEdgeSprites to make sure the baddies don't just fly off. var cool = createSprite(200, 325); cool.setAnimation("cool"); createEdgeSprites(); var group = createGroup(); for (var i = 0; i < 20; i++) { var sprite = createSprite(randomNumber(0, 400), randomNumber(0, 100), 10, 10); sprite.velocityY=randomNumber(5, 10); sprite.velocityX=randomNumber(-5, 5); sprite.bounciness = 1 group.add(sprite); } group.setAnimationEach("mean"); function draw() { background("white"); drawSprites(); cool.x = World.mouseX; group.bounceOff(cool); group.bounceOff(topEdge); group.bounceOff(leftEdge); group.bounceOff(rightEdge); }
var group = createGroup(); group.add(createSprite(200, 200, 100, 100)); group.add(createSprite(200, 100, 50, 50)); group.setSpeedAndDirectionEach(randomNumber(-3, 3), randomNumber(-45, 45)); function draw() { background("white"); drawSprites(); }
var group = createGroup()
Returns the sprite group and assigns it to the variable specified.

command. All images must be first loaded and given a label using the Animation tab above the display window in Game Lab.Found a bug in the documentation? Let us know at documentation@code.org
