Autofire API Help

I am new to the whole API thing and I need some help in creating a piece of code, I don't know what to do. What the code is meant to do is: Take an input in the form of "distance to target". Take that input and compare it to a table to obtain a DC which depends on that distance. Make a skill check using a characters modifier. Compare the check to the DC, and for each point above the DC, the character rolls a damage roll (up to a maximum of 5). I have no idea where to begin with this so please help me.

Just so we're on the same page, APIs are a Pro perk... so you either have to be a Pro subscriber or be playing in a game started by a Pro subscriber. Sometimes people talk about APIs but they really mean just basic macros (no API involved at all). I'm going to assume you really mean API scripts, and that you're playing in a game belonging to a Pro subscriber. In that case, the question is... are you wanting to code your own API in javascript, like a learning project? Or are you looking to leverage existing scripts to do what you need to do? You can probably do a lot of this with the meta toolbox or ScriptCards. Let us know which direction you want to go, and you'll get plenty of help, for sure!

Minor addition that an API script can happily do step 1 for you automatically, instead of needing an input. In fact it's probably the easiest part of the script :)

I have a friend who has Pro and he has asked me to help him with the API, since I helped him with macro's previously, but I have no idea about this stuff.
