I’m using FMOD for the first time for a game and the programmer is concerned about how expensive FMOD is. Basically I have a volume slider that goes from 0 to 1, and whenever the character is in combat I want the slider to slowly fade from 0 to 1. This would require him to set the slider to move up every frame, which he is reluctant to do because that might cause lag or something. Is that a concern he should have? And is there a way to simply set a fade in FMOD to occur over a period of time? So the parameter inCombat would be set to 1 and the fade would automatically start?
