Thanks! Don't forget libraries since there's more than one AsyncOperation
using System.Runtime.CompilerServices;
using System.Threading.Tasks;
using UnityEngine;
This does not seem work with UnityWebRequest
when the request fails (i.e. AsyncOperation.isDone
is set but AsyncOperation.completed
is not invoked). In this case it makes the Task and awaiting routines hang indefinitely.
This probably can't be solved without continuously checking the AsyncOperation.completed
flag somehow?
Thank you a lot for this! I've been having a headache with making Untiy wait for a web request to complete before doing something in a function. This helps solve it, again thanks!

this works fine in addition to UniTask, thank you! you should add these imports on top though:
using System.Runtime.CompilerServices; using System.Threading.Tasks; using UnityEngine;
