Hmm… While it could use a temp buffer of constant recording, just limiting how many seconds it records then throwing away the rest. But that recording would be from the view of the clients player in that case. I thought the killcam showed from the point of view of the killer. It would be too much for the client to record all players into a short temp buffer constantly.
I’d like to hear how to accomplish something like that, as now it has tweaked my interest as to how they do it.
