Moving spotlight, Blurr?

[Mudbill]

You're asking quite a lot here. I assume it's all possible if you spend enough time.

Don't think you can directly move a light object, but surely you can move an invisible entity with a light attached to it.

Blur? I feel like you're talking about a different effect, but I can't seem to picture what that would be, so I don't know. You're not talking about Lens Flares, right? Those are simple enough, I presume, considering they already have a tool for it.

Lastly, sure, you can create some GUI stuff to work your way. I don't know the specifics though, so you'll have to do some experimenting. Maybe create some modules for the player on how to use the sniper.
