Welcome to my(Q11) tutorial on hint brushes, part one. In this
tutorial I will explain the uses of the hint brush surface attribute, that are not covered
in the "Hint brushes
and sky bug" tutorial.
Hint brushes are a technique to decrease in game r_speeds, the speed of game flow, and are extremely usefull in everything from sp, to ctf, to even dm maps. I won't bother explaining why in this tutorial, I'll leave that to my follow up. So to be blunt, hint brushes speed up yer level, and there is no down fall except you can't always use it(that's where area portals come in, but that's another tutorial as well).
Keep in mind the limitations of pixels, this line is infinitly small and would all but touch each wall. Point 1(in red) is the point of the player, though he could never get close enough to the wall, this is the point we use. Without limitations, imagine this perfect line and perfect spot. I won't explain why we need this info, but will keep it simple and tell u what u should do now.
We will now draw a line representing the hint brush. It is the first game unit beloe point 1, and stretches all the way accross the hall and into the walls, but no further.
Keep in mind that the number 1 is a label to a point, not the point, the point is infinitly small. Simple enough to add to a level, and very helpfull in speeds. Now you don't actually draw the LoS line, u aproximat it's position, and when in doubt put it ferther away from "point 1" in the direction the player is coming from. You can now do the same thing as if the player was coming from the other direction and it will not affect the first hint brush. This tool is usefull in any situation when two rooms, with "portals" or door like holes, are seperated by a hall. There will be more info on using hint brushes in my follow up tutorial, as well as exactly why it works, if the tutorial is complete it will be linked below.
