From a simulation perspective, these are two different things. There's no reason a six-second flurry of weapon strikes and an instantaneous explosion of some combustible flask would be simulated in the same way.
As a person who's written actual computer simulations of real-world phenomena professionally, I find that a little odd. Just because in the real world they are different, does not imply that in math, they don't turn up to be basically the same.
An example: in the real world, buying bread is not much at all like flushing a toilet. However, the basic mathematics behind most typical economic models is based on... fluid dynamics! Money can be treated, conceptually, like a fluid, which gives new meaning to the phrase, "spending money like it was water."
