I am a little new to the net yaroze system, so I asking for some help. I have read the documentation thoroughly, and I have poured over the sample source code I could find.Here's my poblem: I want to create a driving game, something similar to, say, Wipeout or Wipeout XL. What I don't understand it how to generate/draw/store the track. Has anyone done this before? Can you offer some advice? I've come up witha few ideas, but I'm not sure which is best: 1. create the entire landscape and track as a giant TMD model. and have the car just move around in it, physically constrained. This, is nice, because not runtime calculation is necessayr, but I'm not sure the net yaroze could handle that much model/texture data in memory. 2 Store the track as a sequence of points in the world coordinate system, and generate the track for each point dynamically. This is can be done in a multiple of ways. I could store an object that represent abou 1 foot of the track and jsut repeat it, or I could actually generate the TMD data. I'm not sure which is better. In addition to the points, I would store a normal vector for each point, so I could have banking turns, hills, etc. What I'd like to find out is if anyone has done this kind of dynamic TMD creation, and if so, could I look at some source code, or documentation? This would be MUCH appreciated. 3. create a set of track segments, like a straight segment, a 30 degree turn, a 15 degree turn, etc. and store the track as a sequence of these segments. This would limit the complexity of the tracks and could get boring. number 2 seems like the way to go to me. I'm just not sure how to tackle the TMD creation. ANY help at all would be greatly appreciated. Please, share your ideas. Thanks. Aidan Dysart adysart@umich.edu
