Glad you like them!

In C++, structs are like classes except every member is public by default. I believe there is no other difference; stack overflow will tell you more, and it told me there is no difference. struct Test { int x; } is the same as class Test { public: int x; } Their memory layout is the same as structs. Every time i think of something that might be different between the two, a google search reveals they can do the same things. Have private members, extend other things, etc. I think the only reason structs exist is for backwards-compatibility, to be honest. I guess just pick one and enjoy. Their only difference is structs are by default public, and classes are by default private.

Awesome! You're one of the rare ones! Thank you!

It's nice to have a node-based system where each node has one or multiple parents as requirements. Those are not too difficult to do, though a quick advice is that it's helpful to separate the node-graph-based code from the skill-tree code.

@@0ia Yep, that's the way to do it, I wasn't sure which way he was going because of the Booleans?? I knew that would be tedious to maintain, so I thought that idea would be rewritten, surprised it wasn't and I thought he would use the decorator pattern to add the skills to the player, it was begging for that (obviously) and I thought that eventually the data structure as a node, a typical solution to a node with a Left and Right node, then you can walk the tree, the user interface code simplifies and you could look at the subtree 1 level below are your choices level up choices, then you write the code once and you have it for all skill trees at all the levels going down as far as you like.

Makes sense! At the time I was torn between trying to keep it simple enough for new C++ users to understand it and starting to add various design patterns to it. I like the node based approach idea in the long run.

@@CodeTechandTutorials Yea! It seems a hard balance, between intimidating beginners versus just getting something that will make sense to them.
