Halo Sniper Rifle Scope

So for the longest amount of time ive had a raspberry pi 3b laying around with nothing for it to do, but recently ive purchased a halo sniper rifle kit and ive been trying to replicate the in game sniper rifle but ive had little to no success.

So i thought that id ask if anyone has any hints or tips i could try since im trying to make it so it has a overlay of the zoom in hud and so it can record audio and video.

 

Any help would be appreciated

 

Maybe you can find it, but there was a an amazing video on YouTube where someone pulled this off. I think it was in several parts, but he never really said how he did it I dont think. He did show the inside of it. That may give you some ideas...

 

I have a few ideas but its just the code i need but i think ive found a maker on tinkernut.com

 

Little sketch of how it could work

 

Ok so ive found the programs one is libpng and the other is dispmanx

And itll be a while since i gotta download both and run a bunch of tests

 

Final draft for the scope now its just working out the files, scripts, and finding a power button for the pi
