Hi, plz could someone help me with a newbie question and a bit of code. I have made an .x terrain file with geoscape but i cant make it show up. When i load the prog it runs but i just get a blank screen. A code snippet to run the file properly would be helpful.
Thx

I tried the code but it still didn't work . The terrain file loads but is not visible.

Zeno,

A couple simple things might be bighting you:

1. How big is the .X terrain you made, in terms of 3D units? It might be too small. In your game loop, try outputting OBJECT SIZE x(objnum), OBJECT SIZE y(objnum), and OBJECT SIZE z(objnum) to the screen as text if you don't know the answer.

If you see small values, like numbers below 10, try SCALE OBJECT and make it bigger.

2. WHERE are you loading the object in relation to your camera? Your camera will have a "near" and "far" range you set with SET CAMERA RANGE. Objects closer or farther away will be clipped. You might try outputting CAMERA POSITION X(), CAMERA POSITION Y(), and CAMERA POSITION Z() to the screen along with the terrain's position. This will show you how close you are to it.

If you don't set AUTOCAM OFF in your program, your camera is going to be moved to the location of the last object you created. You might be too close to see it.

Try explicitly positioning the object and your camera, and pointing the camera at it:

POSITION OBJECT 1, 0,0,0
POSITION CAMERA 50, 10, 50
POINT CAMERA 0,0,0

3. If you have SYNC ON, you'll need to issue a SYNC call or the screen won't be updated and you'll see nothing.

4. If the object completely flat? If so you might be viewing it edge-on and it's so thin you can't see it. If you suspect so, try XROTATE or ZROTATE'ing it between 1 and 45 degrees inside your game loop. You might suddenly see it spin into view and realize you were looking at a 1-unit high flat desert from the side.

Good luck,
Zeno
