As most of you know, each mobile entity contains a "speed" key (parm?). Wanting to make advanced decorations for my map, I need to make each entity work in perfect symmetry with one another. My question is: What is "speed" measured in? Game units per second? If there is no unit it travels in, how many game units (or grid squares in radiant) can an entity with a speed of 100 travel in 1 second?
