Well his “assessment” was a little unfair as you can imagine. he probably tried it for half an hour, stuff didn’t work and then he dropped it. It is in beta still but they are very actively working on it. If you encounter errors and post in their forums they respond fast and fix stuff promptly.
Just to be transparent here, I’m not affiliated in any way nor am I even using it at the moment. i did try it months ago and had mixed feelings, mostly because I lacked time to learn it more in depth. i’m also not unhappy with blueprints and C++ in the first place. I use both in conjunction and it’s awesome. But from someone who is unhappy with the lack of a scripting language I would expect to put in an actual effort to learn Skookum and not just bash it prematurely because some error popped up. How long do you think it would take for a C# equivalent to even get anywhere close to a usable state? There would be bugs and errors all the same.
