Multi Touch Problem

Questions
1

So… I have two controllers that you control with two fingers, one on the left and one on the right. Not long ago, I discovered that if I move my controllers with two fingers moving on the screen, one of the controllers will start glitching like crazy, and will go back and forth different it’s origin position and the position that the finger is at. Is there anyway to fix this problem??

Thanks in advance :slight_smile:

Try this using one or two or all of your fingers. If you want, you can add code to limit the number of touches.

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

function draw()
    background(40,40,50)
    fill(255)
    text("move one or more fingers on the screen",WIDTH/2,HEIGHT-50)
    for z=1,#tab do
        ellipse(tab[z].x,tab[z].y,120)
    end
end

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