Multi-touch function

Hi, I’m new to codea and I’m trying to make a small game from an idea I had.
I saw the Multi-touch sample but I don’t really know how to use it in this case.
Basically I want to have like a line of a fixed length joining two points, if you touch both of the ends you can move and rotate it. I want to know how to get the x and y coordinates of two positions at the same time, so I can use one of those for the position and the other for the rotation angle.
If I’m not clear enough I’m sorry and I’ll try to explain myself better.
Thanks a lot for your help!

Maybe this will give you an idea. Put 2 fingers on the screen and move them around.


function setup()
    tab={}  -- table of touches

function draw()
    for z=1,#tab do
        str=string.format("x = %d     y = %d",tab[z].x,tab[z].y)
        text(str,WIDTH/2,1000-50*z)    -- display x,y values
        if z==2 then    -- only do this for 2 touches

function touched(t)
    if t.state==BEGAN then
        table.insert(tab,vec3(t.x,t.y,    -- put x,y,id in table
    elseif t.state==MOVING then
        for a,b in pairs(tab) do
            if then    -- id matches entry in table
                tab[a]=vec3(t.x,t.y,  -- update x,y,id in table
    elseif t.state==ENDED then
        for a,b in pairs(tab) do
            if then   -- id matches entry in table
                table.remove(tab,a)    -- remove entry from table

.@pmdmaster Correct me if I’m wrong but didn’t someone already make a game like that.

Yeah, it was touchline over at

@beu5mi dave1707 is giving pmdmaster an example of multitouch. The example in this case doesnt reflect the idea in @pmdmaster’s head

@beu5mi Well, that is similar to what I had in mind. We’re making a project for a class with Codea, and this was only to try to understand better how it works and what I can do with it.

Since I don’t have an iPad, I only get access to one during class so I don’t have a lot of time to try other stuff, but I want to understand how to do some things I need for our project so meanwhile I’ll look in this forum and other websites, and ask here if I don’t find something.

@dave1707 Thanks for your help, after I am done with the other proyect I’ll try it. I still want to make this game just for fun, when I have the time for it.
