| The original source code is limited to 60 levels. However, it's possible to expand this amount by making a few simple changes to the engine. In this example, I'll use the code of the "seamless level progression" tutorial, found on the main Codingtips page. I'll show you how to add 4 extra levels, so the maximum will be 64. Using this method, you can add as many levels as you like, until you'll run out of memory (I tested things up to 120 levels without any problems so far). 1. Increasing the maximum number of maps The maximum number of maps to be loaded by the cache manager has been limited to 60. To modify this, open ID_CA.H and you'll see the very first line of code: #define NUMMAPS 60 change this into #define NUMMAPS 64 2. Adding extra map definitions Open MAPSWL6.H and scroll down until you see: MAP4L10PATH_MAP, // 60 LASTMAP Change this into LEVEL61_MAP, LEVEL62_MAP, LEVEL63_MAP, LEVEL64_MAP, LASTMAP 3. Adding par times Open WL_INTER.C and do a search for LRstruct LevelRatios[60]; Change this into LRstruct LevelRatios[64]; Next, locate the line // WOLFENSTEIN PAR TIMES Scroll down until you reach the par time line for level 60, and add 4 extra lines like this: {1, "01:00"}, // level 61 {1, "01:00"}, // level 62 {1, "01:00"}, // level 63 {1, "01:00"}, // level 64 4. Assigning music cues Of course you want the new levels to have some music as well. Open WL_PLAY.C and locate these lines: ULTIMATE_MUS, // Boss level FUNKYOU_MUS Just add four music cue names after these ones (mind the colon!) 5. Adding ceiling colors Open WL_DRAW.C and locate this block: unsigned vgaCeiling[]= { #ifndef SPEAR 0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0xbfbf, 0x4e4e,0x4e4e,0x4e4e,0x1d1d,0x8d8d,0x4e4e,0x1d1d,0x2d2d,0x1d1d,0x8d8d, 0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x1d1d,0x2d2d,0xdddd,0x1d1d,0x1d1d,0x9898, 0x1d1d,0x9d9d,0x2d2d,0xdddd,0xdddd,0x9d9d,0x2d2d,0x4d4d,0x1d1d,0xdddd, 0x7d7d,0x1d1d,0x2d2d,0x2d2d,0xdddd,0xd7d7,0x1d1d,0x1d1d,0x1d1d,0x2d2d, 0x1d1d,0x1d1d,0x1d1d,0x1d1d,0xdddd,0xdddd,0x7d7d,0xdddd,0xdddd,0xdddd Add extra code for the 4 extra levels here (again, mind the colon) 6. Adjusting the Tab-W level cheat You might want to be able to warp to the extra levels as well. Open WL_DEBUG.C and do a search for #ifndef SPEAR if (level>0 && level<61) and change this into #ifndef SPEAR if (level>0 && level<65) If you have more than 99 levels, also make this modification: esc = !US_LineInput (px,py,str,NULL,true,2,0); should read esc = !US_LineInput (px,py,str,NULL,true,3,0); 7. Adjusting the status bar display (99+ levels only) If you want more than 99 levels, you might want the status bar to be able to display 3 level digits instead of two. To do so, open WL_AGENT.C and locate this line: LatchNumber (2,16,2,gamestate.mapon+1); and change into LatchNumber (2,16,3,gamestate.mapon+1); 8. Adding the extra levels to your project data files. Unfortunately, MapEdit cannot handle more than 60 levels. So you either have to use FloEdit's map editor, or you just can design your extra levels in a separate session of MapEdit, export the extra floors into separate floor files and reimport them into FloEdit's map editor using Flo's level import function. To do so, select the "User Defined" checkbox at connection time, and enter 64 levels and a unique extension. Also, don't forget to rename things back to WL6 after the import session. Please refer to FloEdit's helptext for more information about object types and importing levels. CAUTION: once you successfully created a working GAMEMAPS file with more than 60 levels using the method described above, NEVER use MapEdit with this file again to make any modifications. If you do so, your extra maps will be LOST and cannot be retrieved anymore!! An example of 120 levels can be downloaded here (levels 61 up to 119 are all the same, you don't expect me to design 60 levels for demonstration purposes only, I hope :-) It's only there to show you that it actually works. You need the original Wolf data files to run it. Just use the Tab-W cheat or the tedlevel parameter to jump to the higher levels. Success! MCS |
