- DOCUMENTATION FOR NOWHERE.RTL
- RISE OF THE TRIAD LEVEL
- (STANDARD GAME LEVEL)
-
- This package contains an experimental level, NOWHERE.RTL, for the REGISTERED
- version of Rise Of The Triad by Apogee. What began as a game level and WAD
- file analysis routine has now evolved into a level editor for ROTT. This
- game level is my first attempt at creating ROTT maps. (I was analyzing
- the game for my Game Developer magazine/Chopping Block column and found
- the mapping data very interesting, which prompted me to write a level
- editor for experimenting with some of the cool things found in the game.)
- My editor is still in the evolving stage and still displays "undocumented
- features" occasionally, so please excuse any unusual ROTT malfunctions caused
- by the NOWHERE.RTL level. I have tried to make the level as error free as
- possible using my current understanding of how game maps are generated and
- how the 3 planes (Wall, Sprite, and Info) of map data are translated into
- game world features.
-
- Rise Of The Triad screens are drawn using some interesting ray casting and
- sprite manipulation techniques. For example, the sky/ceiling backgrounds are
- drawn using a "tiling" technique as opposed to the "usual" background draws
- of sky and ground texture which is then overlaid with data from the ray
- caster. One really cool effect of this technique is that sky data can be
- tiled around any game wall, floor, sprite, etc. The NOWHERE.RTL level
- takes advantage of these tiling features and therefore gives you a true
- "road to nowhere" effect where floor area is totally surrounded by sky
- tiles - a winding road that sometimes has no beginning or end.
-
- The standard map features such as bad guys, rotating blades, fire chutes,
- doors controlled by keys or touch plate/wall switches, etc. are included in
- the NOWHERE.RTL level just to make things a little challenging. Combine
- these features with the "road to nowhere" features and you end up with a
- very challenging level. I didn't design the NOWHERE.RTL level to be real
- hard or real easy - just an experimental offshoot of the original E1A1 level
- "In The Thick Of It". Here's a few comments about the level:
-
- No RLE file compression is used in the level, hence it is quite a
- bit larger (in bytes) than the original game levels. I haven't
- written file compression into the editor yet. Remember that the
- original game levels are compressed and to alter them you must
- uncompress them, edit the data, and then recompress the data. The
- new size of the edited compressed data will (most likely) be
- different from the original compressed size so you must put the
- new level data into a separate file.
-
- I designed the level so it plays well on my 486DX2/50 system. I
- had to adjust the number of bad guys and other features so the
- game engine would play the level using a good frame rate. If the
- frame rate seems slow, adjust your screen size to increase the
- rate. As you wipe out more bad guys, the frame rate may increase
- because the engine is monitoring/adjusting fewer enemy players.
-
- When walking down the "roads to nowhere", remember that you can
- easily fall off the oftentimes narrow roads, which will cause your
- character to die. Firing a large gun may cause a recoil which
- can push you backwards off the "world". Be careful when using
- jump pads located on the narrow roads since you can easily get
- thrown too far.
-
- All the enemy can/will follow you down the "roads to nowhere"
- just as they normally do.
-
- I found the glass windows and doors especially interesting, so
- you may find these in the level. However, I would advise not
- to blindly shoot out all glass windows/doors since some REAL
- NASTY enemies may be hiding behind them. NOTE: If you DO end
- up confronting the nastiest characters, and you happen to kill
- one (and I'll bet you can't without cheating...), the game engine
- might halt the game because of the internal protections against
- killing BOSS characters on levels other than end-game levels.

-
- RUNNING THE NOWHERE.RTL LEVEL
-
- To play the NOWHERE.RTL level, just run the ROTT setup routine and select
- the "Use Modified Stuff" menu item followed by the "Alternate Levels" option.
- The NOWHERE.RTL level contains only one map, so the game engine will exit to
- DOS once you exit the level.

- THANKS THANKS THANKS THANKS THANKS
-
- I would like to say a BIG thank you to the Apogee Rise Of The Triad
- Development Team for courteously and graciously answering all my questions
- on ROTT game engine and mapping features.
-
-
-
- FINAL COMMENTS
-
- I hope you enjoy this level. Although it only consists of a single map,
- it should give you a good idea of the features obtainable via the use
- of a "generic" ROTT level editor.
