What in What Order?

How do you tell what command goes where when designing a game. Is it in the steps of how you design the game? I know you have to set the scene, lighting, camera etc up first, but after that?

Thanks..

I'm pretty new but the way i'v been reading is:

; Set video mode 
Graphics3D 640,480,16,2
SetBuffer BackBuffer() 
; Setup cameras
cam1 = CreateCamera()
CameraViewport cam1,0,0,640,480

; Load level objects, e.g. meshes, lights, terrain, water plane, skybox, set collisions...
light1=CreateLight()
cube1=CreateCube()
PositionEntity cube1,-2,-2,10

; The MAIN GAME LOOP

While Not KeyHit(1)
     ; Keyboard/Mouse Controls
     ; 3D Stuff, e.g. move/animate meshes, launch projectiles, check collisions...

     UpdateWorld
     RenderWorld

     ; 2D stuff here, update HUD, text, stats...
     Text 50,50,"Hello Cube!"

     Flip
Wend

End

; Subroutines & Functions can be here 

Thats what a basic game code stucture looks like

This code was from a tutorial at http://jnoodle.com/Blitz3D/index.html

thats a realllyyy good tutorial read through it good, it covers most of the basics,

when i'm messing about with code i normal try to keep it nice and tighty by using functions.

Basicly the order is(for me anyways)

Graphics stuff
set the back buffer

global stuff

collisions

cameras
lights

types

Loading stuff, and creating stuff basicly non-realtime stuff

main gameloop

realtime stuff

render and update the world

2d stuff HUD ect

the "Flip" code
end the game loop

functions and data that kinda of stuff that isnt in the main program

Little Addition to Tahfree's code, I would use the same thing but limit the framerate to 60 fps ... As well as forgetting cls.

; Set video mode 
Graphics3D 640,480,16,2
SetBuffer BackBuffer() 
; Setup cameras
cam1 = CreateCamera()
CameraViewport cam1,0,0,640,480

; Load level objects, e.g. meshes, lights, terrain, water plane, skybox, set collisions...
light1=CreateLight()
cube1=CreateCube()
PositionEntity cube1,-2,-2,10

; The MAIN GAME LOOP
;FrameRate
Fps = CreateTimer(60)
While Not KeyHit(1)
WaitTimer(fps)
Cls 
     ; Keyboard/Mouse Controls
     ; 3D Stuff, e.g. move/animate meshes, launch projectiles, check collisions...

     UpdateWorld
     RenderWorld

     ; 2D stuff here, update HUD, text, stats...
     Text 50,50,"Hello Cube!"

     Flip
Wend

End

Thanks folks and Happy New Year!
