Hello hello everybody!
Ok ok it was a new update on codea and I wonder if I can write and if and else statement in codea and
How do I do it. I’m writing a little bit in javascript and found a little cool things example you can make a game easy with
If and else statement and math random and I wonder if I can do this in codea
In JavaScript you can write console.log to print text when you touch a sprite or something
And you can use prompt = (“hello”) my question is can I do this in codea?
Thanks for reading this! And thanks if you can help me 
hello hello. you can do many things in lua language. Read the manual first!
Ok
…
Ok thanks
One more question about this why does this code don’t work it says bad argument
Missing nil or something
function setup()
if print(math.random(1,10)) == 2 then
print("hello winner")
elseif var < 2 then
print("hello noob")
else
print("hello player")
end
end
The line with math.random should not have the print function in it!
Try
if math.random(1,10) == 2 then
Var isn’t a variable yet, you need to make it one.
function setup()
var = math.random(1, 10)
if var == 2 then
print("hello winner")
elseif var < 2 then
print("hello noob")
else
print("hello player")
end
end
Ok thanks!
I promise this is the last question
How can I do a if and else statement when I write something to get a answer
Example-
If I write hello the program will say hello bro
If I write goodbye the program will say see ya later
Or something
Example I was made a game in JavaScript
And it ask the player to write his name
If name == Jonas console.log("hello master ")
And then It asks for my age and if I
You now what I’m meaning…
I now I need to look at the wiki and search by myself but I didn’t find anything
And I want to get started with coding on my iPad because it’s fun and easy.
And where did YOU LEARN TO CODE? please leave a comment how you learned coding
And thanks for reading
@Gamerage Here’s 2 ways to do if/else code like what you want. Or you could use a table for the number compare.
function setup()
-- using a string
answer1("hello")
answer1("whats the weather like")
answer1"goodbye"
-- using a number
answer2("hello",1)
answer2("whats the weather like",2)
answer2("goodbye",3)
end
function answer1(str) -- comparing a string
print(str)
if str=="hello" then
print("hello bro.")
elseif str=="goodbye" then
print("see ya later.")
elseif str=="whats the weather like" then
print("not too good, its raining")
end
print()
end
function answer2(str,v) -- comparing a number
print(str)
if v==1 then
print("hi, how you doing.")
elseif v==3 then
print("where you going.")
elseif v==2 then
print("looks like the rain stopped.")
end
print()
end
@Gamerage13 Check out the wiki, there is a great ebook on learning the basics of lua and codea. It should help you get on track.
If else format.
if var == 1 do
--code here
elseif var < 1 do
--code here
else
--code here
end
```
To print to console
print(var)
--or
print("Hello World!")
```
Random
print(math.random(1,10)) --random number from 1 to 10
```
@Gamerage13 Here’s the example using a table.
function setup()
-- using a number and table
answer3("hello",1)
answer3("whats the weather like",3)
answer3("goodbye",2)
end
function answer3(str,v) -- using a table
print(str)
tab={"good to see you again.",
"do you have to leave so soon.",
"its starting to snow." }
print(tab[v])
print()
end
I was thinking about one thing
In parameters you can write
But can I put the if and else statement in there?
Example if I write hello
The parameter can see that and print hello player
And one more touch when touch detected do this
If touch detected start level or print hello or something
I can code in lua but not on iPad/codea it’s a little bit trickier in here
Because codea does not have the full power like programming in a computer/Mac/PC
Ok thanks for everything! And thanks for helping me!
I now how to write an if and else statement in lua but not in codea
function setup()
parameter.text("TitleText", "hello", function(t) print(t) end )
parameter.watch("string.upper(TitleText)")
parameter.number = io.read()
if parameter.watch == joke then
print("you are a nerd")
elseif
parameter.watch == hello then
print("hello player")
else
print("write something")
end
end
function draw()
background(255, 255, 255, 255)
end
@Gamerage13 Try this. Use the questions “hello” and “is it sunny”, then press answer. Your code wasn’t formatted correctly. The 3 ~'s need to be on lines by themselves. I changed it for you so your code looked correct.
function setup()
parameter.text("question")
parameter.action("answer",answer)
end
function answer()
if question=="hello" then
print("hi, how you doing")
elseif question=="is it sunny" then
print("no, its raining right now")
else
print("I dont know what you're asking.")
end
end
