I’ve just started trying to fiddle with the code to contribute to github rather than just pointing out issues and hoping someone both agrees with me and gets around to coding a fix. I’m currently trying to find a way to code something that checks if all items worn on a specific body part have a certain flag. I’ve been looking through the code for hours trying to find an existing example, but have not found any. I’m not overly familiar with the game’s code so I most likely missed it, I was hoping there would be a simple single function with both a body part and flag argument but it seems I am not in luck.

Could any of you more code-savvy people show me some example code that makes sure every piece of armor on a specific body part, for example bp\_torso has a specified flag, for example OVERSIZE?

player::exclusive\_flag\_coverage does that for the entire body at once (returns a bitset).  
You can use it like:

```auto
const auto coverage = g->u.exclusive_flag_coverage( "FLAG_HERE" );
bool torso_covered = coverage[bp_torso];
```

It would be quite easy to copy it and simplify the copy to just return “false” if any item without flag exists a given body part (or set of body parts).

Thanks, took some time and a bunch of fiddling since this is my first time doing this, but I’ve got it compiled and working.
