Hey, yes but the skill tree is minimalistic.
A 4x4 grid where you can set in skill classes or let them be empty, the costs for the skill, the spended points to unlock the row and an option that needs to have the skill below upgraded.
The upgrading allows you currently to reduce the cooldown or the resource costs.
You can change the grid with a few modifications.
The problem is that there are soo many possibilitys for skill trees that i cant put too much effort in this.
You might not like it or want a different one.
I dont have a problem in doing a better one but that requieres some information what people would want to have.
It is only using a character hierarchy (which is going to be reworked later on to use an interface).
I like the hierarchy more but it might be harder to implement than adding an interface.
The rest is component and ui driven.
Here thats the Hero class that you use to make playable classes.
Most of is UI and the Actionbar.
Im going to extend it over the time but for now its a good start in my opinion.
But for now it is waiting x.X
