A JavaScript tweening library written in TypeScript. Requires TS version >= 4.0.
There are a few ways to create a Tween.
The tween
factory function.
import { tween, Tween, Easings } from '@akolos/ts-tween';
const point = {
x: 0,
y: 0,
};
const target = {
x: 10,
}
// Moves the x-coordinate to 10 over one second in a linear fashion.
const xTween = tween(point, target, {easing: Easings.linear, length: 1000});
// Also available as a static method on `Tween`
const yTween = Tween.start(point, {y: 10}, {easing: Easings.linear, length: 1000});
The step-builder methods.
const myTween = Tween.get(point).to(target).with({easing: Easings.linear, length: 1000});
Creating a factory (useful when many of your tweens will have the same easing/length).
const pointTweenFactory = Tween.factory({ easing: Easings.outCubic, length: 1000 });
const xTween = pointTweenFactory(point, { x: 10 });
const yTween = pointTweenFactory(point, { y: 5 });
A traditional builder.
const tween = Tween.builder()
.easing(Easings.linear)
.length(1000)
.tween(point, {x: 5, y: 5});
A group is a collection of multiple tweens that can be treated as one.
const xTween = Tween.tween(point, target, { easing: Easings.linear, length: 1000 });
const yTween = Tween.tween(point, { y: 10 }, { easing: Easings.linear, length: 1000 });
const xAndYTween = Tween.group([xTween, yTween]);
xAndYTween.seek(500);
A sequence is an ordered group of tweens, where each tween has its own specified starting time.
// Tweens x first, then tweens y.
const sequence = Tween.sequence()
.append(xTween)
.append(yTween)
.start();
