How to remove Persistent Variables?

[ajcross]

How are persistent variables deleted from memory?

Is it done by setting these to "-1" or the empty string ""?

I know you can set pvars to negative values, so the "-1" wouldn't work, and you can set them to a null string, so "" won't work. Actually, once they are created, I believe they are there to stay, until you exit the game.

Why would you want to?

[ajcross]

I thought that they were getting saved when the game was saved. I don't want to accidentally overflow that area.

I also want some variables to reset between missions.

You need to reset them yourself. When a pvar is modified for the first time, it is "declared" and given a value of zero before the add/subtract. If you use the set pvar text to text action, then it is given that value.

I always "declare" my pvars at the beginning of a mission, esp. to avoid the ?pvar? error. If you want to use pvars between levels, and don't want values carried over, then set them at the start.

So if I were using pvars to, say, keep track of how many Rocket Troopers the player owns, and the player saves the game and exits the mission, will the pvar be preserved when the player reloads the mission?

Yes it will.
