RAW

[KindWiz424]

I'm trying to set up a program where you can play data based on sine waves that you draw

Not sure how ittl turn out with multiple coordinates on the same point but I'm willing to find out

--[[RAW]]--
x=1
y=1

draw.setscreen(1)
draw.touchmoved(touches)

q={}
v={}

while(a==true) do
o=o+1
i=i+1
a=touches[o].x
r=touches.y
draw.point(a,r,draw.black)
table.insert(q,a)
table.insert(v,r)
end

sleep(1000)

while(q==true) do
rate=44100
channels=2
bits=16
data={q[h] * 2 * v[h]}
buffer={rate, channels, bits, data}
audio.playebuffer( buffer, 27, 369, 0 )
end

Why is touchmoved undefined
Is there anything else I absolutely need to do?

[Admin]

You should define touchmoved
for example:

function touchMoved(touches)
— some code that reads touches
— x = touches[1].x
end
draw.touchmoved = touchMoved


Also touches variable should be read inside touchMoved function.

Please read some intro documentation for lua then read touch examples like paint.lua

[Lol]

This is my (faulty) interpretation of this

--[[RAW]]--

v = sys.input("record for:")
x=1
y=1

draw.setscreen(1)

q={}
k={}
function touchMoved(touches)
draw.lineto(touches[1].x, touches[1].k, gray)
end
sleep(v)
draw.touchmoved=touchMoved

while(a==true) do
o=o+1
i=i+1
a=touches[o].x
r=touches.y
draw.point(a,r,draw.black)
table.insert(q,a)
table.insert(k,r)
end

sleep(1000)

while(q==true) do
rate=44100
channels=2
bits=16
data={q[h] * 2 * k[h]}
buffer={rate, channels, bits, data}
audio.playebuffer( buffer, 27, 369, 0 )
end

Do I need touch began and touch ended on this?

If not why won't it do anything

[KindWiz424]

I added the touch began and end

record for:456

Runtime Error:
RAW.lua:29: RAW.lua:13: bad argument #3 to 'lineto' (table expected, got nil)

< Program Ended >

Is what I get

Do you know how to fix it so it at least does something?

[lol]

"Grey" through me off

So it needs to be read inside a function

This might take a while

[Lol]

Ahh! I have to append


function touchMoved(touches)
draw.lineto(touches[1].x, touches[1].y, draw.black)
end

I need to use all the touches[1]

did you import draw library:
require "draw"

please take it step by step and learn Lua first

[KindWiz424]

Well I got it so it draws from point 1 to another point 1 ect

But it barely makes a sound

How do I make "touches" a table of all [1]s?

I know you just said to learn it myself though so I'm not expecting a response

[Lol]

I gotta ask
How do you achieve greater touch[id]?

you can read one touch at a time and add it to some global table.
To deal with tables, I recommend to read and apply this tutorial on lua console:
lua-users.org/wiki/TablesTutorial
if you still find it hard to understand start reading from the beginning:
lua-users.org/wiki/TutorialDirectory
if you want to become a programmer, you need to get used to read documentation 

good luck
