What is UNITASK_ASYNCINSTANTIATE_SUPPORT?

[ilakhin]

AsyncInstantiateOperation was added since Unity 2022.3.20 / 2023.3.0b7:

• https://unity.com/releases/editor/whats-new/2022.3.20
• https://unity.com/releases/editor/beta

I didn't find a define like UNITY_2022_3_20_OR_NEWER to restrict the methods.

Unity doesn't add new APIs in patch versions. It was added in 2022.3.0, so you can use UNITY_2022_3_OR_NEWER.

Unity 2022.3.19f1 does not support this API. It was added in a patch version (https://unity.com/releases/editor/whats-new/2022.3.20).

Oh I missed it in the notes because of the weird formatting. Player: Added: Object.InstantiateAsync<T>().... Ugh, Unity doing stupid things so much.

There is a new define in 2022.3.20f1 that can be used instead of #if UNITASK_ASYNCINSTANTIATE_SUPPORT:
#if UNITY_2022_3_20

I assume it's supposed to be #if UNITY_2022_3_20_OR_NEWER, but we'll know for sure once 2022.3.21f1 comes out.

I've come up with the following define. It's not elegant but it does what you want.

// 2022.3.20f1 or newer
#if UNITY_2022_3_OR_NEWER && !(UNITY_2022_3_0 || UNITY_2022_3_1 || UNITY_2022_3_2 || UNITY_2022_3_3 || UNITY_2022_3_4 || UNITY_2022_3_5 || UNITY_2022_3_6 || UNITY_2022_3_7 || UNITY_2022_3_8 || UNITY_2022_3_9 || UNITY_2022_3_10 || UNITY_2022_3_11 || UNITY_2022_3_12 || UNITY_2022_3_13 || UNITY_2022_3_14 || UNITY_2022_3_15 || UNITY_2022_3_16 || UNITY_2022_3_17 || UNITY_2022_3_18 || UNITY_2022_3_19)
