OK, here's my chess timer:

print("Chess timer starting...")
--function variables
local drawRectFill = zmg.drawRectFill
local fastCopy = zmg.fastCopy
local makeColor = zmg.makeColor
local drawPoint = zmg.drawPoint
local keyMenuFast = zmg.keyMenuFast
local clear = zmg.clear
local drawText = zmg.drawText
local keyDirectPoll = zmg.keyDirectPoll
local keyDirect = zmg.keyDirect
local floor = math.floor
local random = math.random
local time = zmg.time
local ticks = zmg.ticks

--screen vars
local SCREEN_WIDTH = 384
local SCREEN_HEIGHT = 216
local exit = 0

--game variables
local key = {F1=79, F2=69, F3=59, F4=49, F5=39, F6=29, Alpha=77, Exit=47, Optn=68, Up=28, Down=37, Left=38, Right=27, EXE=31}
local chesstimer = {timerStart=60, add=0, turn="White", turnNum=1}

local continue = 0

local start=0

--first poll and first start timer
keyDirectPoll()
local startTime = ticks()

local function timeElapsed()
return floor((ticks()-startTime)/100)
end

local function wait(timeToWait)
local start = timeElapsed()
while timeElapsed() - start < timeToWait do end
end

local function waitForKey(key)

end

end

local function introScreen()

drawText(1, 1, "WAIT...", color.fg, color.bg)

--refresh screen

end

print("done.")
print("")

For some reason it freezes at "Press [EXE] to continue". I've been debugging it for a half an hour with no results so maybe someone with a fresh brain can help me see where my problem is?

I have started a project I am calling pong++. It is based on pong but will have lots of different modes.

So far I have this:

print("starting...")

print("defining functions")
--function variables
local drawRectFill = zmg.drawRectFill
local fastCopy = zmg.fastCopy
local makeColor = zmg.makeColor
local drawPoint = zmg.drawPoint
local keyMenuFast = zmg.keyMenuFast
local clear = zmg.clear
local drawText = zmg.drawText
local keyDirectPoll = zmg.keyDirectPoll
local keyDirect = zmg.keyDirect
local floor = math.floor
local random = math.random

print("setting vars")
--screen vars
local LCD_SCREEN_WIDTH = 384
local LCD_SCREEN_HEIGHT = 216

--game variables
local key = {F1=79, F2=69, F3=59, F4=49, F5=39, F6=29, Alpha=77, Exit=47, Optn=68, Up=28, Down=37, Left=38, Right=27}
local color = {makeColor("limegreen"),makeColor("black")}
local ball = {x=20, y=20, width=8, height=8}
local dir = {x=1, y=1}
local speed = {x=2, y=2}
local paddle = {player=40, width=8, height=30, speed=4}
local wall = {width=8}


print("entering game loop")
----game loop----
while keyMenuFast() ~= key.Exit do
----DRAW----
--draw background
drawRectFill(0,0,LCD_SCREEN_WIDTH,LCD_SCREEN_HEIGHT,color[2])

--draw ball
drawRectFill(ball.x, ball.y, ball.width, ball.height, color[1])

--draw player paddle
drawRectFill(0, paddle.player, paddle.width, paddle.height, color[1])

--draw wall
drawRectFill(LCD_SCREEN_WIDTH-wall.width, 0, wall.width, LCD_SCREEN_HEIGHT, color[1])


----CONTROLS----
--control paddle
if keyMenuFast()==key.Up and paddle.player>0 then paddle.player = paddle.player - paddle.speed
elseif keyMenuFast()==key.Down and paddle.player<LCD_SCREEN_HEIGHT - paddle.height then paddle.player = paddle.player + paddle.speed
end


----COLLISIONS----
--check for collisions
if ball.x < 0 + paddle.width and ball.y > paddle.player and ball.y < paddle.player + paddle.height then ball.x = 0 + paddle.width dir.x=1
elseif ball.x < 0 then print("Game Over") break
end

if ball.x>LCD_SCREEN_WIDTH - ball.width - wall.width then ball.x = LCD_SCREEN_WIDTH - ball.width - wall.width dir.x=-1
end

if ball.y<0 then ball.y=0 dir.y=1
elseif ball.y>LCD_SCREEN_HEIGHT - ball.height then ball.y = LCD_SCREEN_HEIGHT - ball.height dir.y=-1
end

----ETC----
--make new vars
ball.x = ball.x + (dir.x * speed.x)
ball.y = ball.y + (dir.y * speed.y)

--refresh screen
fastCopy()

--[[--
--debug
print("ball.y:" .. ball.y)
print("ball.x:" .. ball.x)
--]]--

end
print("exiting.")

As you can see I have a basic pong game set up there. It is totally playable, just paste it into notepad or whatever, save it, and send it to your calc. If you get errors, please post them.



The main reason I am posting this is because I have not come up with many ideas for different modes. The ideas I have come up with are:

* Slug: Make the paddle move very slowly. I will probably make this something that happens in-game as a penalty or whatever, not as an actual game mode.

* Spread: have two player paddles that move away from each other symmetrically from the center.

* Obstacles: Have obstacles in the middle of the screen.

* Multiple balls: self-explanatory, I think. Have more than one ball to keep track of.

Please post your ideas!


If you can give me tips on optimization, by all means do!

I think that there may be a faster way of clearing the screen than drawing the background every frame, but I am too lazy right now to figure that out.

Just curious about how many people read ebooks on their calcs.

I read gutenberg.org ebooks on my prizm with Noteview.

OK, having a problem with PHP.

Here is the code i have:

<select name="formSelect">
<option value="value1">value1</option>
<option value="value2">value2</option>
</select>

<form action= "<?PHP echo "upload.php?" . $_POST["formSelect"]) ?>" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="userfile" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>

And its not working.

What I want it to do is make the form action equal upload.php?formSelectvalue .

Can anyone help?

EDIT:

Fixed it by putting <select> inside the <form> tags

Hi all!

Working on my first game in LuaFX. So far all that happens is the ai cars try to avoid you.

Code: http://pastebin.com/5EWqXNzf

I am having trouble with the collisions detection right now... for some reason ai cars can "run over" you and you do not get the crash screen. The detection is done on line 231.


If people could test this program that would be great, so I have provided a *.lc for download:

Is anyone thinking about porting axe to prizm?

Is anyone working on a font hack for the prizm os? Or maybe even allowing users to choose their own font? I personally don't like the default font

Is Veb planning on porting luaFX to PRIZM?
