@bhob12 - this is where you should read the built in docs. Look in the Animation section, for tween.sequence.
@bhob12 If you want to animate something look at the built in docs and the animation example as @Ignatz suggests.
If you need to call a function after x amount of time you can use tween.delay(). You will need to trigger it as it runs one time. If you want to call a function every x seconds you can do this:
function setup()
delay(3)
end
function delay(d)
tween.delay(d,function() print("Hello World") delay(d) end)
end
I suspect that you are wanting to use this for animations, in that case @Ignatz is correct with tween.sequence()
I’m still finding the whole tween.delay troubling… how do you use it. The built in codea description isint helping…
How do I draw a triangle and fill it in?
How do I draw a triangle and fill it
So:
Fill(12,12,35)
Then what?
@bhob12 You can draw a triangle with “line”, but there isn’t an easy way to fill it in. To do that, you need to use a mesh. Here is a simple example that draws a triangle and fills it with the color red.
function setup()
myMesh = mesh() -- define mesh
myMesh.vertices = {vec2(100,100),vec2(200,200),vec2(200,100)} -- coordinates
myMesh:setColors(255,0,0) -- set the color red
end
function draw()
background(40, 40, 50)
myMesh:draw() -- draw the triangular mesh
end
Thanks a lot
How do I (use) a sprite.
@bhob12 Move you finger around the screen.
function setup()
dx=WIDTH/2
dy=HEIGHT/2
end
function draw()
background(40,40,50)
fill(255)
text("move your finger around the screen",WIDTH/2,HEIGHT-100)
sprite("Planet Cute:Character Cat Girl",dx,dy)
text(dx,WIDTH/2,HEIGHT-200)
text(dy,WIDTH/2,HEIGHT-250)
end
function touched(t)
if t.state==MOVING then
dx=dx+t.deltaX
dy=dy+t.deltaY
end
end
How do I text a variable so that it appears on the screen but the value can change therefore the # on the screen can change with it (because they’re the same)
@bhob12 See the above code. I added 2 text statement in the draw() function to display the x and y location of the sprite as you move it around.
How do I add iAd … Also how would I use the keyboard on the ipad/iPhone and type with it on the computer? Thx
iAds involve an exported Codea project in Xcode and some knowledge of Obj-C.
On Macs, you can use your hardware keyboard when the virtual keyboard appears.
–I know my code isn’t very pretty and I know that it is hanging by a thread 
but help is still very much appreciated. –
–My current problem is as follows: I have created a variable called “score”. A value of 1 is added to it every time a sprite called “img” passes off the screen inbetween two lines. If the “img” were to touch one of the two lines on either side of the screen the game would end and what im trying to make happen is for the score to actually say the correct # instead of 0. It says 0 because every time the sprite goes of the screen it is redrawn at the top of the screen. –
–if blueY <= 5 then
blueY = HEIGHT
blueX = math.random(0,WIDTH)
sprite(img,blueX,blueY)
score = score + 1
end–
–The “score” variable is 1 for a short moment but then when the “img” is redrawn at the top of the screen the score is back to 0 because blueY no longer is <= 5.–
–As always I’m very thankful to those who respond and try to help.–

–The image is a spritely I made so I put it in a new class and called the image “img”.–
–The code for that is below–
@bhop12 You’re always setting score=0 in your “if play” section in draw(). You should probable set score=0 in setup and menu.
@bhop12 Here’s your code. I commented out the score=0 in draw. I added blueX=blueX+Gravity.x*5 at the end of draw to move the sprite when the iPad is tilted. I also changed “img” to a sprite I have because I don’t know where img was coming from.

Wow thanks a lot this is really helpful and I’m thankful.
When I run my codea project in xcode, (in the ios simulator) it still has the parameter bank in the left of the screen and the four icons in the bottom of the left hand corner are still there… I’m not sure why they’re there. Can someone help
Are you using
