Help with Lua

[yaustar]

i told you shadowblind! my computer sucks! so what;s wrong with it?

That comment wasn't aimed at you, it was at Shadowblind.
Your problem here is that you dont have a problem or not describing well enough.

What are you trying to do?

oOOOooohhh.....so what do i do with the blank text again? by the way, here is a pic of that "test" looks like on my computer "the blue thunder looking thing"

shadow i had the same problem thats why i just used my psp

[yaustar]

I know full well what it looks like. I dont understand what the hell is your problem that you are trying to convey. Are you trying to run your own Lua script?

@Shadow: Is the .cmd or .bat file in any other program besides notepad?

.....i'm trying to make a game....but first i want to start up that lua thing i need to make it.

You do realise that LuaPlayer is NOT like GameMaker, Games Factory or Click and Play. You have to program for it like BASIC, Pascal, C/C++ etc.

Here is an example of a lua script/program that you run WITH LuaPlayer VIA batch files:

-- 2006-07-03
-- Added a pause and reset animation functions

-- 2006-07-02
-- Very quick and hacky animation test by yaustar
-- Note there are some REALLY bad practices here.

-- Preload some colours
GREEN = Color.new(0, 255, 0);
WHITE = Color.new(255, 255, 255);
BLACK = Color.new(0, 0, 0);

-- Constants for the various animations
Int_Standing = 1;
Int_Walking = 2;
Int_Attacking = 3;

-- Load the images
Image_Ken = {};
Image_Ken[Int_Standing] = Image.load("./KenStanding.png");
Image_Ken[Int_Walking] = Image.load("./KenWalking.png");
Image_Ken[Int_Attacking] = Image.load("./KenDragonPunch.png");

-- Properties for the Ken Sprite
KenSprite = {
Int_XPosition = 30,
Int_YPosition = 30,
Int_FrameWidth = 40,
Int_FrameHeight = 117,
Int_NumberOfFrames = 6,
Int_CurrentFrame = 0,
Int_FrameDelayInMs = 120,
Int_CurrentFrameTimerLapseInMs = 0,
Bool_Pause = false,
Int_State = Int_Standing,
Int_NumberOfTimesLooped = 0;
};

-- The update function for a sprite. Regulates the time between each frame and loops the animation
function UpdateGraphic(Sprite, Int_DeltatimeMs)
-- Check if the animation is paused
if not Sprite.Bool_Pause then
-- Update the timer lapse
Sprite.Int_CurrentFrameTimerLapseInMs = Sprite.Int_CurrentFrameTimerLapseInMs + Int_DeltatimeMs;

-- Check if the lapse is more then the Frame Delay
if Sprite.Int_CurrentFrameTimerLapseInMs > Sprite.Int_FrameDelayInMs then
-- If so, move to the next frame
Sprite.Int_CurrentFrame = Sprite.Int_CurrentFrame + 1;
-- Reset the Lapse
Sprite.Int_CurrentFrameTimerLapseInMs = Sprite.Int_CurrentFrameTimerLapseInMs - Sprite.Int_FrameDelayInMs;
end

-- Check if the current frame is the last one
if Sprite.Int_CurrentFrame == Sprite.Int_NumberOfFrames then
-- If so, loop back to 0
Sprite.Int_CurrentFrame = 0;
-- Increment the loop counter
Sprite.Int_NumberOfTimesLooped = Sprite.Int_NumberOfTimesLooped + 1;
end
end
end

-- Function to stop and resume the animation of a sprite
function PauseResume(Sprite)
Sprite.Bool_Pause = not Sprite.Bool_Pause;
end

-- Function to reset the animation of a sprite
function ResetAnimation(Sprite)
Sprite.Int_CurrentFrame = 0;

end

-- Function to check if the animation has finished
function CheckIfAnimationHasFinshed (Sprite)
if Sprite.Int_NumberOfTimesLooped > 0 then
return true;
else
return false;
end
end

-- Modify the state of the sprite
function ModifyState(Sprite, Int_IntendedAction)
-- If the Sprite is standing, then it can go to walking or standing
if Sprite.Int_State == Int_Standing and Int_IntendedAction ~= Int_Standing then
ResetAnimation(Sprite);

end
-- If the Sprite is walking, then it can go to attack or standing
if Sprite.Int_State == Int_Walking and Int_IntendedAction ~= Int_Walking then

return true;
end
-- If the Sprite is attacking, then do nothing
if Sprite.Int_State == Int_Attacking then
-- Do nothing
return false;
end

return false;
end

-- Update the sprite state
function UpdateState(Sprite)

-- If the Sprite has finsihed the attacking animation then go back to standing
if CheckIfAnimationHasFinshed(Sprite) then

Sprite.Int_State = Int_Standing;
end
end
end

-- Move the sprite by X and Y amount
function MoveSprite(Sprite, Int_X, Int_Y)
Sprite.Int_XPosition = Sprite.Int_XPosition + Int_X;
Sprite.Int_YPosition = Sprite.Int_YPosition + Int_Y;

*breathes*
I try this another way. What are you expecting LuaPlayer to be?

screen:print just so u know its not smilies lol

@fg: u code in the notepad silly
