The shotgun ended up being way too powerful during play. I couldn't figure out a way to get more spread from the transmitting devices available. The dome LEDs weren't bright enough. a single dedicated LED wasn't bright enough. I think this is because the dome receiver has a fixed gain to make the long range barrel LED more selective. But using the radio to transmit shotgun blasts - because it goes everywhere and transmits through walls - it didn't feel like shooting a gun anymore. This method will come back in the form of some other weapon - like a gravity hammer or energy sword. 

So I thought maybe instead of trying to create a real spread, I could simulate a spread. What if the shotgun sent out its IR message repeatedly and very quickly in one burst that would cover the span or two AR shots. That should in theory guarantee that the shotgun can interrupt an AR, and the spread of the shotgun is determined by how much your aim moves after you shoot. I can limit the effective range still by using the radio RSSI messages. On the bench it works, will test soon

at first yes, I knew I was probably going to have to mask out repeated shots - but during gameplay, I actually liked the repeated shots. It kind of works more like a real shot gun - the more buckshot you land, the more damaging the hit. I just made each individual shot less damaging.

The AR can receive hits in between shots. An AR versus a shotgun might look like this:

AR: _||__________||__________||__________||__________||__________

SH:_||_||_||_||_||_||_||_||__________________________________________

If I read in data from my IR sensor while I'm sending packets, I end up reading in my own packets, so I am temporarily ignoring the IR sensor while shooting.

Sending the message repeatedly is an interesting way to try to "increase the spread." 

I've tried all sorts of LED's, from 3W versions to 120 degree beam angle SMT's, and during the day, I can't get them to register more than five feet or so during the day and outside. At night, it works a lot better, but I want to be able to play during the day, so I decided to not go with any of those for my current version.

Are you worried about getting hit by multiple shots?

And you mentioned in your description that the Assault Rifle makes you "temporarily invincible". How are you receiving the tags sent?
