},
{

src: "assets/fonts/myFont.ttf"
}]
const audiosList = [{
key: "alert",

},
{

const jsList = [{

resourceManager.addEventListener("start", () => {
console.log("Resource loading starts")
})
resourceManager.addEventListener("progress", (e) => {
// e.detail.totalResources display total resources to load
// e.detail.loadedResources display loaded resources
// e.detail.percentage display percentage
console.log("Progress", e.detail)
})
resourceManager.loadResources({
images: imagesList,
videos: videosList,
fonts: fontsList,
audios: audiosList,
diverses: diversesList, // return an fetch() response
css: cssList, // append automatically in <head></head>
js: jsList // append automatically in <head></head>
}).then(async (message) => {
// all resources are loaded, do what you want after
console.log(message);
const myJson = await resourceManager.getDiverse("myJson").json(); // return an JSON parsed data
console.log(myJson);
}).catch((err) => console.error(err));You need define one key for each item. The keys are unique for each category. Methods available for fetch your resoures are:
- getImage(key)
- getVideo(key)
- getFont(key)
- getAudio(key)
- getDiverse(key)
- getJs(key)
