Duke Nukem 3D was based off of the Build Engine created by Ken Silverman, with said engine being designed to be HIGHLY modifiable. On top of that, Duke3D came pre-loaded with tools and examples to help people get into modding the game with minimal effort! Still, starting with a blank slate is always intimidating, so this inaugural episode of ADG Mod will cover how to mod Duke Nukem 3D, with an emphasis on level design since that's the simplest aspect to get into here by far, though other aspects such as the GRP, CON and ART files are briefly touched on. ------------------------------------------ Additional Information and Corrections: * Here's a link to the eDuke32 Wiki: http://wiki.eduke32.com *And a link to the Duke Nukem 3D Informational Suite: http://infosuite.duke4.net/ * One trick I forgot to mention which can really help when modifying slopes and heights: If you hold down the left mouse button at any point, it will "lock" the selection to whatever the cursor is over until you let go of the button. This is very handy so you don't constantly have to keep the cursor over what you're trying to modify. * One of the few features which is not well documented is "Visibility". While you can change the brightness of surfaces using the keypad plus and minus keys, each sector itself also has a visibility setting which determines how quickly brightness falls off with distance. Curiously, the default value of 0 wraps around backwards to 255, with 240 being the "lowest" value, resulting in absolutely no brightness falloff, while 239 is the "highest" value where you pretty much can't see more than a few inches in front of you. * Keep in mind that some entities in the game are designed to behave differently when given different palette settings. Also be aware that if you change the palette of a floor you're also setting the lighting colour of the sector, thus everything in that sector will take on the floor's palette colour. ------------------------------------------ Pixelmusement Website: http://www.pixelships.com ADG on Pixelmusement: http://www.pixelships.com/adg Alphabetical Index of ADG Episodes: http://www.pixelships.com/adg/index2.html Kris' Patreon Page: https://www.patreon.com/kasick @Pixelmusement on Twitter: https://twitter.com/Pixelmusement
