## Example
|
|
```js
|
|
import { KBTween } from ".../tween.js";
|
|
import { easings } from ".../easingpackage.js";
|
|
|
|
var k = kaboom(); // Make Kaboom global but also a variable
|
|
var twnlib = KBTween(k); // Create new TweenLib instance, pass in Kaboom
|
|
// This fixes Intellisense on VSCode not picking up on how Kaboom imports plugins
|
|
// Otherwise, if your IDE is smart enough, you can just pass in the tween lib normally, using KBTween as a plugin
|
|
loadBean();
|
|
|
|
var bean = add([
|
|
sprite("bean"),
|
|
pos(64, 64),
|
|
color(255, 255, 255)
|
|
]);
|
|
|
|
twnlib.tween(bean.pos, [ "x" ], {
|
|
from: 0,
|
|
to: width() - 64,
|
|
time: 3.2,
|
|
type: 8
|
|
});
|
|
|
|
twnlib.tween(bean.pos, [ "y" ], {
|
|
from: 0,
|
|
to: height() - 64,
|
|
time: 2,
|
|
type: 8
|
