Hahah, thanks! I suck at explaining things sometimes…
kvick’s explanation of linear interpolation is really good and explains why lerp is the one to use rather than interp as I mentioned. Interp is framerate independent (it uses world delta time) and as you need it to control something visual…you see where I’m going with this…
It’s refreshing to see other people doing audio visual stuff rather than generic zombie survival games, I’m also writing an audio visual program using ue4 so it’s cool to see others using it in similar ways.
I’m keen on seeing what you end up with so make sure you upload some vids here
