I don't have any code, I've tried a bunch of things. I'm a sort of new scripter, and I want to find out how to make the dialog bubble pop up on command. For example, I click a button, and a model or character says something without me having to click on a bubble. I've seen it in some games where it appears above the player who clicks the button. They will say something they didn't actually type. I don't really know how to phrase this well, but if you don't understand just ask me.
Just put in the dialog into a NPC head then put in a dialog choice. Pretty self explanatory from there.
Hopefully that's what you meant.
