It's really just passing information from one thing to another. Like passing a note in class. Like with a triggeraction, the destination script has no way of knowing what, say, your level is, unless you send it through the triggeraction. Say you have a gani for hammer, and you have different levels of hammers, level 1, level 2, gold hammer, and different images for each hammer. You can make ONE gani show different images for each level of the hammer, instead of a gani for each level. But, it must be told what level the hammer is, so you pass it through a parameter.
