Thanks Jay, I did some measuring, and it had very little impact on performance. It turns out, near misses are pretty frequent (must be those 30 raytrace/sec weapons)!
Nic2: Try putting the call to SetSurroundingBoundsType at the end of the spawn function, just in case something in the baseclass is overriding it -Teddy On 1/16/07, Jay Stelly <[EMAIL PROTECTED]> wrote:
I tried to answer this in the wiki page: "USE_SPECIFIED_BOUNDS could also be used to solve this problem by specifying a constant box that is always larger than the space occupied by hitboxes in any animation. As a tradeoff, this will be cheaper than USE_HITBOXES as the player animates and moves, but more a conservative boundary resulting in more hitbox queries happening against ray tests that miss. The highest performance method will depend on the mod's number of players moving vs. number of ray/box traces computed against players (and how many of those queries actually miss)." It really depends on several variables (like how many rays are near misses, the number of hitboxes and the complexity of the player skeleton). The only way to determine "exactly how much" is to measure it in your mod. HL2 uses this method for striders' bounds so it's not insanely expensive or anything, just more expensive when you have only a few ray traces nearly missing players in a frame. It may be less expensive if you have a enough rays being rejected as a result or less expensive if the animation of the player varies enough to require a large enough USE_SPECIFIED_BOX.
