Events using up MP

If I wanted to have doing some events take up MP what is the best way to do this? Currently I have the event subtract 5 MP after doing it, but how does the system know that the character had 5 MP to spare before allowing the event? Also I need to tie in t not allow other similar events to happen if the character has below 5 MP. I also need help changing the term MP to maybe EP for Energy Points. Any help is much appreciated.

To change the name go to the terms tab in the database.

To check the MP the character has use Control Variable with Game Data -> Actor X's MP

I guess you already figured out how to subtract MP?

to have it know if the player has enough mp just put a conditional branch where if the actor has x mp then it does what you want, otherwise it will do something else if they do not.

edit: sorry bro, didnt see the other post, im on my phone. anyways, just trying to help.

I'm a little slow. Could you post a screenshot of doing the control variable with game data? Maybe it was too late last night but I couldn't figure it out.

I guess you can find Control Variables in the event commands yourself?

here's the rest:

You are my new best friend thank you Moby.
