Resetting space on hot reload?
With Svelte, I have this component:
<script>
import {onMount} from "svelte"
import {CanvasSpace, SVGSpace, } from "pts"
let node: HTMLElement
let space: CanvasSpace | SVGSpace
onMount(() => {
space = new SVGSpace(node).setup({ // tried SVG and canvas
})
const player = myFunction(space)
space.add(player)
space.bindMouse().bindTouch().playOnce(1000)
return () => { // this runs on unMount
// none of these help
space.dispose()
space.removeAll()
Array.from(node.children).forEach((c) => c.remove())
space = null
}
})
</script>
<div bind:this="{node}"></div>
In dev, Svelte hot reloads all changed files, including this component and imports. This triggers the unMount/onMount functions, which I expected to fully reset the space. Instead, Pts is retaining state somewhere. Is there a better way to reset everything?
SVG and canvas seem to have different behavior.
SVG: start()
works including on remount, animate()
doesn't.
Canvas: start()
runs but no form
functions do anything (even on first load), animate()
works including on remount.
Thanks for reporting this. I probably need to look into Svelte a bit more to get a better sense.
One potential suggestion: Would it work better if you pass the animate as prop, instead of const player = myFunction(space)
? Eg,
export let animateFn;
onMount( () => {
// ...
if (animateFn) animateFn( space, form );
});
