Below is the code for an infinte landscape I made.(DBP only)

"GrassTiles.bmp" is a 2*2 set of 4 grass tiles, each slightly different.

"lake1.bmp" is just a simple lake texture.

Insert your own files/names for these things

You can use the arrow keys up/down to accelerate/decelerate.
And left/right to turn.
You can only controll your speed when your "on the ground". (ie. You can't brake in the air).

Any advice or help on improveing the following would be helpfull:
[B]
* Smoothness.

There is a slight jerkyness to the movement, I think this is caused when the camera wraps around every 200.
Any ideas how I could get rid of it?

* Camera Banking.

I thought this would be simple, I simply want the camera to tilt left or right according to the "rightTspd"/"lightTspd" values.
Any advice? code please?
I tried using Roll/Camera Rotate, but I either got no result, or a camera that never rolled back when the Turn speed went back to Zero.


* FOV

The field of view changes dianamicaly to make your movement look faster.
What do you think of this techique?
Any ideas how I could make it smoother? (is half values possilbe?)
[/B]

Thanks, any help in any area, or any comments on the code would be nice

You don't need to do an UPDATE MATRIX after one of the SHIFT MATRIX commands. If you remove it that should remove the stall that you get.

I was wrong with my original post (I think it's DBC that doesn't need the update after a shift), so just for that, I've fixed your code so that (hopefully) it does what you want.

Just search the code for 'IanM' to see what I've changed.

Yes, Indeed, that is an improvement.
Thanks a lot
hmz...gota work out why now :p

I mean, surely moving back 100 every 100 units is the same as repositioning at the start?
hmz...

ReD_eYe ~ Thats odd, works fine for me (both codes).

You can only move when your on the ground, btw.
Does the new code help?

wait, theres a mistake in it:
"if CH0 then Spd=spd-1"
should be
"if CH=0 then Spd=spd-1"

Ok, ill check this out and get back to you's.
Id like to try to get that FOV thing working smoothly if possible, I like the exadurated speed effect it gives, but as you say you get "stuttering".

Yes, it didn't post right ... again. It's actually cut out quite a lot of code. Something like:

ok, heres the latest version if anyones interested

www.darkflame.co.uk/SkyScraper.zip

It now use's a 8*8 tilemap(included), and has a height based tileing system.
Looks much better, allthough my textures need a lot of work
Ive also made some sanded bit near the lake.

Does anyone know why my fog isnt showing up?
Dosnt fog work on Matrixs?
Im trying to hide the pop up a bit you see.

As usual, any other comments or improvements are welcome.

you have to set the matrix to react to fog using 'set matrix' i think

Thanks ill try that

nope...didnt work...in fact, I think the fog is on but its not responding to by colour command (hence I thought it was lighting)

The relivent part of my code (above) is:

Fog on
Fog Color 0,0,256
Fog distance 5000

Surely this should make the matrix turn blue the further away it gets?
