willblaschko / data.json
Created March 24, 2019 22:53
An example of using nested APL elements (Containers, Pagers) to achieve over 200 items in a relatively small payload. Use sparingly, this starts to have impact on performance of rendering.

willblaschko / spriteAnimations.js
Created March 23, 2019 22:20
An example of how to create rough APL sprite animations using Pagers and sequential page commands. Your mileage may vary on smoothness of transition based on other commands being executed.

let spriteCommands = [];
for (...) {
...
spriteCommands.push({
"type": "SetPage",

Last active March 23, 2019 22:13
A Node.js support function (and example Sequences) that quickly creates all the commands required to animate a multi-item Sequence, including customization to control speed, jump, and whether the animation reverses.
module.exports = {
animate: function (componentId, count = 7, delay = 20, jump = 1, reverse = true) {
let commands = [];
for (let i = 0; i < count; i += jump) {
commands.push({
"type": "ScrollToIndex",
"componentId": componentId,
"index": i,

willblaschko / RequestHandler.js
Created March 3, 2019 12:25
Inside the RequestHandler, override the ResponseBuilder to be able to send multiple "speak" requests to concat. This makes it easier to pass between different handlers/functions, each can add a preamble if required (e.g. "Game over..." + "Starting a new game").
const RequestHandler = {
process(handlerInput) {
//log our request
console.log("REQUEST ENVELOPE = " + JSON.stringify(handlerInput.requestEnvelope));
//required function taken from Alexa SDK
function trimOutputSpeech(speechOutput) {
if (!speechOutput) {
return '';

willblaschko / LocationBitmapTransformation.java
Last active September 19, 2016 05:17
A Glide transformation to set the center of the crop()--similar to cropCenter(). This only affects the overflow dimension, not the fit dimension.
