Modding Help Need explanation for weapon parameters

Hi, I'm currently trying to make a weapon mod. But I don't understand all the weapon parameters. Can anyone please explain those briefly?
The difference between fireTime and fireTimeFactor or energyUsage and energyUsageFactor. If I change the factors the value of damage per shot, rate of fire, energy per shot change but if I change fireTime or energyUsage nothing changes.
What are burstTime and burstCount?

 

I now understand that the problem is on the buildweapon.lua file. What is the behavior of this file?

 

Honestly you can change parameters without having to do lua.files which I don't recommend using for beginners in modding , the most important parameters are inside the .activeitem files , don't bother with lua files unless you've been already modding a lot.
Try the activeitem files for novakids weapons since they're pretty basic and make a good base to start modding
