Hey Bro, how are you?
Thank you for your question and interest,
believe it or not, I'm working on an update to this plugin right now. The schedule suggests I should be able to release it this weekend if all the tests go well.
A community user asked me if he could modify variables directly with the skill tree earlier. In the current version, he couldn't, so I started working on the option to allow triggering a common event. This will allow that when he acquires a skill, it is (purchased) and activates a common event that changes the value of the variables he wants. I think it's a cool addition, but while working on it, I realized that node editing only allows one type of action at a time: either you turn on a switch, or you call a common event, or you change a skill. Ideally, there would be an auxiliary switch-to-switch system, so that when you acquire a shadow element skill, for example, the entire branch of light skills disappears.
So I'm adding a visibility lock switch parameter, and an automatic trigger parameter, in addition to the common event trigger mentioned earlier.
This way, the system will be more flexible and adaptive, and it will certainly solve your problem.
The plan is for this weekend; if everything goes well, I'll let you know here when it's all ready.
Thank you for your message and for all the support!
Let's create amazing games, bro!
