How to set size to a Texture2D after an await?
I am using Unity in Hololens with UWP, so I have a few async/await calls. However, when I try to do;
var height = await ...;
var width = await ...;
var foo = new Texture2D(width, height);
it throws an exception
Internal_Create can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don't use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
How can I still construct a Texture2D after an await call when the necessary information is available?
You can't change your Unity world in another thread than the main thread. You will have to write your results into some variable and wait in Update or a coroutine to use them. Feel free to use this class like this:
void Start()
{
StartCoroutine(DoStuff());
}
private IEnumerator DoStuff()
{
var height = 0;
var width = 0;
yield return new CoroutineThread(() =>
{
// Do Thread stuff here
});
ResultStuff(width, height);
}
