This is a question, which I've looked around on the internet but couldn't find a tutorial. Does anyone know how to make a working "un-manned" catapult in Hammer for TF2? That means, it's like a sentry but has longer range. I don't want it to target players, I want it to launch and hit at certain areas. To further what I mean, I want it to be on a timer so that it launches at certain times. It will hit in certain locations and can be destroyed. Is this possible? I've seen something similar to this before, but I don't know how I'd go about doing this.
