Im a new Custom Story Maker. Any guidance?

[CeftKuro]

Basically i found the script for applying force/impulse to a prop/body but im slightly confused about it because the website i guess assumes im smart and already know what all the terminology is. So far what i have is this:
void AddBodyForce(string& Corpse_Male_1, float afX, float afY, float afZ, string& world);
What i want to happen it the Male Corpse 1 to be forced along the X Axis. Period. In a nut shell i want that cold dead thing to just be launched out of the closet hes hiding in.
Lastly i have all that in a txt ext, what ext does it have to be and where should it be located? ( as far as in the custom story folders go)
