I am here with a request that's both simple and complex. I'll try to speak only the essentials, but if you want more details, just ask: First, some background. In my game, each actor will have a few variables associated with them. My question has to do with common events affecting those variables. In a nutshell, I intend to have skills that hit a certain actor be able to affect the variables associated with that character. Events could do it too, but they can be done more easily with the engine. I want the skills to "feed" three constants into the common event, being used to define the actor, the specific variable targeted and the operation the common event will do. My question is simple, how do I set up the script to be able to "feed" those constants into the event? And what do I write in the event to "receive" those constants to do all those things? Small follow-up question: Are these variables persistent? Will they remain the same even when the game is closed and opened back? If not, I'll have to do some more things to make this work.
