REJECT.EXE version 1.0.0 Copyright (C) 1994 L.M.Witek lee@trousers.demon.co.uk 1.0 Introduction ---------------- REJECT.EXE is a command line based utility used for building the REJECT resource in a DOOM PWAD file. It post-processes a PWAD which has been created using a level editor such as DEU. Its main purpose is to speed up slow PWAD files by reducing the number of line-of-sight calculations performed by the DOOM engine. REJECT.EXE is freeware. 2.0 Legal bit ------------- This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation.

All the information required to run and operate REJECT should be provided in this document. Before using REJECT: ********************* READ THIS DOCUMENT! ********************* My spare time is limited so I will not respond to any queries if the answer is to be found in this document. However I would be glad to here from anyone who thinks they have found a bug in REJECT or has any ideas on how to improve REJECT. The source to REJECT is provided in the file SOURCE.ZIP you are free to use all or part of the source in your own programs, however if you do I would be grateful if you would credit me in some way. If you create a enhanced version of REJECT from the source provided I would be grateful if you would send the modified source to me so I can put the enhancements into the 'official' version. I will not support any versions of REJECT other than those built by myself. Please _DO_NOT_ send me any large binary files (such as your latest PWAD) as email without my prior consent. My time on the net is limited as I have to call long distance to my Internet Access provider and my phone bill is large enough already. If any mail to me bounces then try sending to: lee%trousers.demon.co.uk@demon.co.uk Email from outside the UK sometimes goes missing. I'm not sure why but I am looking into it. Using the longer address should always get to me. Only use the long address if mail to the shorter address fails. This will allow me to see where I am having problems recieving from. 4.0 Requirements ---------------- REJECT is a 32 bit DOS extended program built with SYMANTEC C++ v6.11. Any machine which is capable of running DOOM will (should :->) be capable of running REJECT. 5.0 Usage --------- REJECT is run from the DOS command line. The syntax is: REJECT Where: = Name of the WAD file to process. Don't add .WAD onto the end of the name. = The map name to modify. REJECT will only process one map at a time so if you have more than one map in your WAD then you need to REJECT multiple times. = The distance at which sectors are rejected. See next section for explanation of this parameter. eg: reject mywad e1m1 600 NOTE: REJECT writes back to the original wad so make a backup before using. Having said that it hasn,t corrupted any of the wads I've tried it on. Both DEU and BSP will overwrite the reject table in a wad file so run REJECT *AFTER* you run either of these utilities. I use a simple batch file to control the edit/run cycle: deu bsp mywad.wad reject tmp e1m1 600 doom -file tmp.wad If you want it to dump a load of debug info use the DOS command SET DEBUG_DEVICE=REJECT.LOG will dump into the file REJECT.LOG which you may (or may not) find interesting. :-> 6.0 Operation ------------- REJECT works by reading the map specified and creating a list of all the sectors which exist in the map. It then takes each sector in turn and compares the distance of all the other sectors. If this distance is less the THRESHOLD parameter the the sector is 'ACCEPTED' in the reject table. If the distance is greater than the THRESHOLD parameter then the sector is 'REJECTED' and DOOM will not perform line of sight calculations for that sector thereby speeding up the operation of DOOM. The exact value of the THRESHOLD varies greatly from WAD to WAD but start by using 600 and see if the game play is acceptable.
