Hello, I'm a new mapper, currently have a big one in progress and I have a few questions. First off, what is hint exactly(I know it can reduce r_speeds and such), such as what does it do, how do you use it, and what visual effects does it have? I've read many tutorials and still clueless. Now, in addition to said map, I have a deadline for a different kind of map. The map in question is going to be a simple museum for one of my projects and I need help on simply how to set the trigger to run an informative .wav file from a speaker.
