Hammer Tutorial #21 optimization Part 4- Area Portals

In this set of 5 tutorial you will learn optimization 101. Optimization is making your map run better, and result in better game play. When done correctly you will also learn how to majorly cut down on compile times. Common terms you may not know but will encounter: World brush: a brush that isn't tied to any entity Skybox: the collection of "tools/skybox" textured brushes that cover the top of your map, giving the appearance of a sky 3d-skybox: see above, only instead of an appearing sky projects another part of the map Framerate, or FPS (frames per second): how fast your map runs, the higher the smoother, the better! Compiling: To turn an editable map into a playable map vbsp: The first compiling program, takes care of general BSP structure, and portalling vvis: The second compiling program, takes care of visibility, can take hours on an unoptimised map, luckily can also take seconds if optimised right vrad: The third and last compiling program, takes care of ( the static ) lighting your map bsp: Binary space partitioning, basically a format to write and use maps (originally ported from Quake) Console commands: Sv_cheats 1 Mat_leafvis 1 Mat_wireframe 3 Things covered in these tutorials: Tutorial 1 - func_detail, and skybox. http://www.youtube.com/watch?v=O44wZitRJwo Tutorial 2 - solving leaks, fish bowl therey http://www.youtube.com/watch?v=UdC_8ROx6yQ Tutorial 3 - hint and skipping http://www.youtube.com/watch?v=31hZH-RCwGM Tutorial 4 - area portals http://www.youtube.com/watch?v=uOOJkk8-OUw Tutorial 5 - occluders http://www.youtube.com/watch?v=xhJPAeKB7-0 Links on this subject: Custom game menu with dev command button: http://files.tophattwaffle.com/Game%20Related/GameMenu.res Written guide to optimazition: http://rvanhoorn.ruhosting.nl/optimization.php?chapter=intro Vvis: http://developer.valvesoftware.com/wiki/Vvis Leaks: http://developer.valvesoftware.com/wiki/Leaks Areaportals: http://developer.valvesoftware.com/wiki/Areaportal Occluders: http://developer.valvesoftware.com/wiki/Occluder An indepth look on visleafs: http://developer.valvesoftware.com/wiki/Visleaf Hint brushes: http://developer.valvesoftware.com/wiki/Hint_brush Skip brush: http://developer.valvesoftware.com/wiki/Skip Visibility optimazition: http://developer.valvesoftware.com/wiki/Controlling_Geometry_Visibility_and_Compile_Times ********************************************** All, and any downloads you may need are here: http://www.tophattwaffle.com/?page_id=63 ********************************************** Download this tutorial: http://www.tophattwaffle.com/?page_id=188 ********************************************** Contact Info: Steam: Doogiehoogie AIM: Doogiehoogie E-Mail: [email protected] X-Fire: rocketrascal34 FPSBanana: http://www.fpsbanana.com/members/144386 Skype: TopHATTwaffle Ventrilo: http://www.tophattwaffle.com/?page_id=175 Youtube: Rocketrascal34 Website: www.tophattwaffle.com Follow me on Twitter: https://twitter.com/TopHATTwaffle Support me on Patreon: https://www.patreon.com/tophattwaffle
