With a mailto openurl call. Have a look at this thread:
In the urn I had this bug (by using the code):
The picture does not seem to be uploaded
So, he said: UNEXPECTED SYMBOL NEAR ‘<\194>’ - so I could not open the project
Why don’t you try just learning basic Lua first?
@yojimbo2000, @ignatz, why Codea hasn’t got any reference for io, assert, type and many other tags, why isn’t there any reference?
@TokOut It takes time to write documentation and the developers can’t add new functions to Codea and write documentation for everything. A lot of information can be found in the Lua reference. If you want to write documentation for anything not in the reference, you can. If it’s written well enough, the developers could add it to the reference.
But @dave1707, I have found an documention for io.lines
It was something like for line in io.lines do and in the example he would draw many lines. But actually he didn’t Drawen anything. I thought something like not all tags where programmed for lua. For the tag typeits something like a nil tag. It is only highlighted. I will try to find something…
I learned tables, what know?
meshes, vectors, then practise, practise, practise until you are good at programming all these things
@mentioned; This is my code, I was trying to understand why by touching DOWN, It will go UP
if self.hold then
if self.holdMode == UP then
self.body:move(0, 3)
elseif self.holdMode == DOWN then
-- Problem point TO-FIX [He is going Up!]
self.body:move(0, -3)
elseif self.holdMode == RIGHT then
self.body:move(3, 0)
elseif self.holdMode == LEFT then
self.body:move(-3, 0)
end
end
The class self.body:move has got x and y attributes so you have to reset -3 to go down but wether 3 or -3 is working
More code: The Body:move function:
function Body:move(x, y)
if x == nil then x = 0 end
if y == nil then y = 0 end
self.x = self.x + x
self.y = self.y + y
end
More code: The touched function
function World:touched(t)
if t.state == BEGAN then
if t.x>25 and t.x<75 and t.y>25 and t.y<75 then
-- LEFT
self.holdMode = LEFT
self.hold = true
elseif t.x<150 and t.x>100 and t.y<75 and t.y>25 then
-- DOWN
self.holdMode = DOWN
self.hold = true
elseif t.x>175 and t.x<225 and t.y>25 and t.y<75 then
-- RIGHT
self.holdMode = RIGHT
self.hold = true
elseif t.x>100 and t.x<150 and t.y>100 and t.y<150 then
-- UP
self.holdMode = UP
self.hold = true
end
elseif t.state == ENDED then
self.hold = false
end
end
I need help! I have trouble with window moving! Can someone say me the problem? When I move the window he got stuck at many points! But I need to have a move without stuck points, I removed the thing. Here is the main code:
Window = class()
function Window:init()
self.drawing = true
self.pos = vec2(0, 0)
self.size = vec2(400, 250)
self.logo = readImage("Cargo Bot:Codea Icon")
self.action = function() print("The window was clicked!") end
self.name = "Test Window"
self.fontSize = 25
self.closeable = true
self.logo_size = 45
end
function Window:draw()
if self.drawing then
fill(255, 255, 255, 255)
rect(self.pos.x, self.pos.y, self.size.x, self.size.y)
stroke(0, 0, 0, 255)
strokeWidth(2.5)
line(self.pos.x, self.pos.y+self.size.y-50, self.pos.x+self.size.x, self.pos.y+self.size.y-50)
sprite(self.logo, self.pos.x + 25, self.pos.y+self.size.y-25, self.logo_size, self.logo_size)
fill(0, 0, 0, 255)
font("AmericanTypewriter")
fontSize(self.fontSize)
text(self.name, self.pos.x+self.size.x/2, self.pos.y+self.size.y-25)
if self.closeable then
fill(255, 0, 0, 255)
stroke(0, 255, 50, 255)
strokeWidth(1)
rect(self.pos.x+self.size.x-45, self.pos.y+self.size.y-45, 40, 40)
fill(255, 255, 255, 255)
font("AmericanTypewriter-Bold")
fontSize(40)
text("X", self.pos.x+self.size.x-25, self.pos.y+self.size.y-25)
end
end
end
function Window:touched(t)
if t.state == BEGAN and self.drawing then
if t.x>self.pos.x and t.x<self.pos.x+self.size.x and t.y>self.pos.y and t.y<self.pos.y+self.size.y then
self.action()
if self.closeable and t.x>self.pos.x+self.size.x-45 and t.x<self.pos.x+self.size.x-5 and t.y>self.pos.y+self.size.y-45 and t.y<self.pos.y+self.size.y-5 then
print("Window Closed!")
self.drawing = false
end
end
end
end
Put this code in Window:touched(t). I don’t know why you can’t figure this out yourself.
if t.state == MOVING and self.drawing then
if t.x>self.pos.x and t.x<self.pos.x+self.size.x and t.y>self.pos.y and t.y<self.pos.y+self.size.y then
self.pos=vec2(t.x-200,t.y-125)
end
end
Oh, I didn’t thought about vectors 
Hurray! I learned meshes!
@TokOut You said you didn’t think about vectors, yet the code you posted has vec2’s and you’re using them all over the place.
@dave1707 yes but I thought about t.x + 1 = self.pos.x + 1 which was bugging
I need help with meshes, I expected a rect:
function setup()
m = mesh()
m.vertices = {vec3(0, 0 , 0), vec3(WIDTH, 0, 0), vec3(WIDTH, HEIGHT, 0), vec3(0, HEIGHT, 0)}
m.colors = {color(255, 255, 255, 255), color(223, 216, 145, 255), color(167, 255, 0, 255), color(239, 0, 255, 255)}
end
function draw()
background(0, 0, 0, 255)
m:draw()
end
