Again here's the code, which probably belongs here as well as prizm programming, for now it's just source code; I'm trying to figure out how to write and convert it into luaZM or to the prizm SDK in C.
As promised here

Is where you may find the original author, as well as the software it was made on (condition of source use). But really the place is quite nice for programming Lua.

Ok so I'm having some issues, and I'm setting up the global Variables right now, tell me how this looks
Code: ---PRiZM ENDURO---
---Main.Lua---
-- global screen size constants
HEIGHT=216
WIDTH=384
bottomY = HEIGHT *.21
trackWidth = WIDTH * .9 -- width of the track at the bottom
horizonY = trackWidth * .55 + bottomY
trackHeight = horizonY - bottomY
trackLength = 100 -- in meters
-- main objects
myCar = nil
cars = {}
day = nil
track = nil
-- various global variables
speed = 0 -- for showing to the user
location = 0 -- my location
maxPosition = -1000 -- the location relative to me where the front-most car is
lastCollisionT = -1000 -- last time i collided, for the penalty
gameTime = 0 -- for reporting to the user
startTime = 0 -- the time at which the game started
days = 1 -- which day we're on
carsToPassInit = 150 -- on day 1 we need this many
carsToPass = carsToPassInit -- how many cars to advance to the next day
gameOver = false
gameStarted = false -- whether the user has started the game
gamePaused = false
maxSpeed = 150
regularSpeed = 85

Looks like code to me.
What issues are you having? From what I can see, all you're doing is (correctly) declaring global variables.
Note that for this:
Code: bottomY = HEIGHT *.21
trackWidth = WIDTH * .9 -- width of the track at the bottom
horizonY = trackWidth * .55 + bottomY
You might want:
Code: bottomY = math.floor(HEIGHT *.21)
trackWidth = math.floor(WIDTH * .9) -- width of the track at the bottom
horizonY = math.floor(trackWidth * .55 + bottomY)
Here's the update, with NEW CODE!
Code:
---PRiZM ENDURO---
---Main.Lua---
-- global screen size constants
HEIGHT=216
WIDTH=384
bottomY = math.floor(HEIGHT *.21)
trackWidth = math.floor(WIDTH * .9) -- width of the track at the bottom
horizonY = math.floor(trackWidth * .55 + bottomY)
trackHeight = horizonY - bottomY
trackLength = 100 -- in meters
-- main objects
myCar = nil
cars = {}
day = nil
track = nil
-- various global variables
speed = 0 -- for showing to the user
location = 0 -- my location
maxPosition = -1000 -- the location relative to me where the front-most car is
lastCollisionT = -1000 -- last time i collided, for the penalty
gameTime = 0 -- for reporting to the user
startTime = 0 -- the time at which the game started
days = 1 -- which day we're on
carsToPassInit = 150 -- on day 1 we need this many
carsToPass = carsToPassInit -- how many cars to advance to the next day
gameOver = false
gameStarted = false -- whether the user has started the game
gamePaused = false
maxSpeed = 150
regularSpeed = 85
function setup()
track = Track()
day = Day()
myCar = Car(0,0,0)
myCar.speed = 120
end
What I do to increase speed is make all the vars local. I don't know if you would want to do this or not

This is technically okay if all code being used is within a single file; locally-defined variables can still be global to entire file, or "chunk", if they're conceived outside of all blocks and strctures like normals globals. I'm not sure how LuaZM supports Lua programs over multiple files, but with a single file declaring everything as 'local' is a very good idea.
All my code for the enduro clone is in 1 file, as it is written as one on the iPad Codea, also after this work will come an asteroids clone (after I finish the iPad port)
Oh, cool, can't wait for asteroids
yup, I'm going to do Lua only for the prizm so hopefully as I learn, many programs/games will come from me in lua on the Prizm.
Same here. I found C was a little above my level but I have always been comfortable with Lua.
Lua=love beginners c=just don't care about anything
well I'm home the rest of the week, can't really open my mouth and the muscles hurt, so looks like unless I have work to do, I'm free to keep porting enduro

Well it's 1000 lines, idk how it's going to turn out, but I'm trying! Also if not enduro I'd be trying asteroids or something of the like, I feel it's the on,y way for me to ever learn this, without goals I just piddle around and never accomplish anything

That's how I am too... I understand you completely.
1000 lines...wow. I wrote a racing game once but it was only 400 lines.

Perfectly respectable. Speaking of Lua racing games, I think there was an Nspire Lua project called Indy 500 that someone posted about a while back; I should see if I can find the topic about that.

That was my LuaFX game

OK so here's what I've got down, and I'm curious...where do I begin using libs from luaZM?
Code:
---PRiZM ENDURO---
---Main.Lua---
-- global screen size constants
HEIGHT=216
WIDTH=384
bottomY = math.floor(HEIGHT *.21)
trackWidth = math.floor(WIDTH * .9) -- width of the track at the bottom
horizonY = math.floor(trackWidth * .55 + bottomY)
trackHeight = horizonY - bottomY
trackLength = 100 -- in meters
-- main objects
myCar = nil
cars = {}
day = nil
track = nil
-- various global variables
speed = 0 -- for showing to the user
location = 0 -- my location
maxPosition = -1000 -- the location relative to me where the front-most car is
lastCollisionT = -1000 -- last time i collided, for the penalty
gameTime = 0 -- for reporting to the user
startTime = 0 -- the time at which the game started
days = 1 -- which day we're on
carsToPassInit = 150 -- on day 1 we need this many
carsToPass = carsToPassInit -- how many cars to advance to the next day
gameOver = false
gameStarted = false -- whether the user has started the game
gamePaused = false
maxSpeed = 150
regularSpeed = 85
function setup()
track = Track()
day = Day()
myCar = Car(0,0,0)
myCar.speed = 120
end
print("Instructions:")
print("Press Shift to accelerate")
print("Press Alpha to break")
print("Press nothing to maintain speed")
print("Use Prizm D-pad to Steer")
print("F1 to Start")
function draw()
rectMode(CORNER)
ellipseMode(RADIUS)
speed = myCar.speed
------------- UPDATE GAME STATE ----------------
if not gameOver then
if not gameStarted or gamePaused then
stoppedUserInputs()
else
accelerating = runningUserInputs() -- start, left, right, brake, etc
-- move track around
turnTrack(gameTime,track)
-- move the day forward in time
day:updateMode(gameTime)
if gameStarted then
gameTime = ElapsedTime - startTime
location = location + DeltaTime*myCar.speed/100
spawnNewCars()
myCar:updateTireState()
day:updateFogEnd(myCar.speed)
end
LuaZM implements the standard Lua libraries and an additional zmg lib for Prizm-specific native aphids and other generic functions. A list of ZMG lib functions and what libraries aren't functional yet:

Thanks ashbad, I've read over the references for LuaZM for 2 days now, but looking at the code I have so far, I can't see where as of yet I need the ZMG commands
