First, download and copy this empty project which includes all the images and the p5.play library.
Animations are like images, you preload images and you display them in a certain place. The library takes care of storing and advancing the frames.
Creating animations from single images:
[js]
//animations like p5 images should be stored in variables
//in order to be displayed during the draw cycle
var ghost, asterisk;
All front sprites have been adjusted to 125% and back sprites are 175%. Some animations may play slightly faster (like 0.1s per frame faster) due to the method I used for sharpening. As far as I can tell this IS noticeable; but it actually makes a lot of sprites look more consistent. Don't worry 'cause it only affects little things like.

That question is nominally about spritesheets because they are mentioned in the title, but the question is mostly about animation techniques for generating the frames used in a spritesheet. $ endgroup $ – jhocking Apr 12 '12 at 0:04.
//it’s advisable (but not necessary) to load the images in the preload function
//of your sketch otherwise they may appear with a little delay
function preload() {
//create an animation from a sequence of numbered images
//pass the first and the last file name and it will try to find the ones in between
ghost = loadAnimation(“assets/ghost_standing0001.png”, “assets/ghost_standing0007.png”);
//create an animation listing all the images files
asterisk = loadAnimation(“assets/asterisk.png”, “assets/triangle.png”, “assets/square.png”, “assets/cloud.png”, “assets/star.png”, “assets/mess.png”, “assets/monster.png”);
}
function setup() {
createCanvas(800,300);
}
function draw() {
background(255,255,255);
//specify the animation instance and its x,y position
//animation() will update the animation frame as well
animation(ghost, 300, 150);
animation(asterisk, 500, 150);
}
[/js]
Creating animations from a sprite sheet requires two steps:
1. loading and processing the sprite sheetsprite_sheet = loadSpriteSheet(filename, frame width, frame height, number of frames);
2. loading the animation
explode_animation = loadAnimation(sprite_sheet);
Try to load an animation you made in piskel, you just have to change the parameters in loadSpriteSheet.
[js]
var sprite_sheet_image;
var sprite_sheet;
var explode_animation;
function preload() {
// specify width and height of each frame and number of frames
sprite_sheet = loadSpriteSheet(‘assets/explode_sprite_sheet.png’, 171, 158, 11);
explode_animation = loadAnimation(sprite_sheet);
// load the full sprite sheet for example reference only
sprite_sheet_image = loadImage(‘assets/explode_sprite_sheet.png’);
}

}
function draw() {
background(255);
// animate the sprite sheet
animation(explode_animation, 100, 130);
// show full sheet for example reference
image(sprite_sheet_image, 250, 40, 500, 154);
}

p5 play facilitates the creation of objects called sprites. Sprites are visual entities existing in a 2d space. They have coordinates, they can be assigned an appearance (images and animations) and specific functions for physics, collision or interaction.
A sprite is created once and it doesn’t need to be drawn every time.
The function drawSprites(); usually called at the end of the draw cycle will take care of all the visualization.
[js]
var boxSprite;
function setup() {
createCanvas(800,600);
//create a sprite with a placeholder rectangle as visual component
boxSprite = createSprite(100, 150, 50, 100);
}
function draw() {
background(240);
//draw all the sprites
drawSprites();
}
[/js]
Here is how to create an animated sprite and some functions to control the animation
Don’t forget to check the examples and the reference
[js]
//Changing the sprites’ animations
var character;
var spriteSheet;
//preload the spritesheets
function preload() {
//load from spritesheet
spriteSheet = loadSpriteSheet(‘assets/explode_sprite_sheet.png’, 171, 158, 11);
}
function setup() {
createCanvas(800,300);
//create a sprite and add the 3 animations
character = createSprite(400, 150, 50, 100);
//label, first frame, last frame
//the addAnimation method returns the added animation
//that can be store in a temporary variable to change parameters
character.addAnimation(“floating”, “assets/ghost_standing0001.png”, “assets/ghost_standing0007.png”);
character.addAnimation(“moving”, “assets/ghost_walk0001.png”, “assets/ghost_walk0004.png”);
character.addAnimation(“spinning”, “assets/ghost_spin0001.png”, “assets/ghost_spin0003.png”);
var explodeAnimation = loadAnimation(spriteSheet);
character.addAnimation(‘explode’, explodeAnimation);
}
function draw() {
background(255,255,255);
//keyDown returns true for a cycle if the key was just pressed
//during this cycle. Useful to capture instant events in the draw cycle
//without moving game logic to the mousePressed() function
//mouseWentDown works the same way with mouse input
if(keyWentDown(“a”) )
{
character.changeAnimation(“moving”);
}
if(keyWentDown(“s”) )
{
character.changeAnimation(“spinning”);
}
if(keyWentUp(“s”) )
{
character.changeAnimation(“floating”);
}
if(keyWentDown(“d”) )
{
character.animation.stop();
}
if(keyWentUp(“d”) )
{
character.animation.play();
}
if(keyWentDown(LEFT_ARROW))
{
character.animation.previousFrame();
}
if(keyWentDown(RIGHT_ARROW))
{
character.animation.nextFrame();
}
if(keyWentUp(“f”) )
{
character.changeAnimation(“explode”);
character.animation.rewind();
}
//changing an animation when another one is done
if(character.getAnimationLabel () “explode” && character.animation.getFrame()character.animation.getLastFrame())
{
character.changeAnimation(“floating”);
}
//draw the sprite
drawSprites();
}
