Summary

A basic approach to acceleration and turning. Allows full and easy customization. Allows for textured/randomized matrix.

Full Description

Heavilly commented, studying it for a few seconds/minutes you can get how simple this is. You can use this in your games if you want. But if you do, a little bit of credit would be great. When you first run the program, the matrix will be a wireframe. Also, at the top of the code you will notice a lot of variables. Those are there so you won't have to go deep into the code in order to adjust simple things. This works well, allowing you to make minor adjustments easilly. If there are any errors, tell me and I will try to fix the bugs. And remember, this isn't supposed to be anything fancy. No AI, no models, no lighting, no objects even! Just a matrix, a camera, and a lot of variables. Enjoy! :^ )

rem important variables

maxspeed = 100

turn = 2.0

sharpturn = 4.0

acceleration = 2

dacceleration = 1

minspeed = 0

rem basic neccesary stuff

sync on

speed = 0

hide mouse

backdrop on

rem load image " ", 1

rem texture backdrop 1

rem setup basic matrix

make matrix 1,10000.0,10000.0,25,25

rem below are the codes to make random, textured matrix. Just take

rem out the rems and put in a file name for the load image command

rem load image " ", 2

rem prepare matrix texture 1,2,2,2

rem randomize matrix 1,100.0

rem Position camera

position camera 5000,200,5000

rem Begin loop

rem set speed parameters

if speed < minspeed then speed = minspeed

if speed >= maxspeed then speed = maxspeed

rem move the camera based on speed variable

move camera speed

rem Control camera with arrow keys

if upkey()=1 then speed = speed + acceleration

if upkey()=0 then speed = speed - dacceleration

if downkey()=1 then speed = speed - 5

if leftkey()=1 and shiftkey()=1 then angley#=wrapvalue(angley#-sharpturn)

if rightkey()=1 and shiftkey()=1 then angley#=wrapvalue(angley#+sharpturn)

if leftkey()=1 then angley#=wrapvalue(angley#-turn)

if rightkey()=1 then angley#=wrapvalue(angley#+turn)

rem Update camera

xrotate camera 0.0

yrotate camera angley#

zrotate camera 0.0

y#=get ground height(1,x#,z#)+50.0

rem print basic info

set cursor 0,0

print "Controls: UP: move accelerate. DOWN: deceleterate. "

print "Left: Turn left. Right: Turn Right."

print "Shift + turn keys: sharp turning."

rem print the information to be placed inside of the Heads Up Display (HUD)

set cursor 0,400

print "FPS: "; Screen FPS(); "  "; "Speed: "; speed
