taps 2, 3 and 4

[rusty]

hi, i'm having a play with touch sequence on android...

basically i have a hud with 5 labels on it.
i call "input.enableMultiTouch(this.getUser(), true)" in init and set the hud.
then do the following

Code: Select all

function main.onTouchSequenceChange ( nTaps0, nX0, nY0, nTaps1, nX1, nY1, nTaps2, nX2, nY2, nTaps3, nX3, nY3, nTaps4, nX4, nY4 )
--------------------------------------------------------------------------------
   
    local hUser = application.getCurrentUser()
   
   
    local h0 = hud.getComponent(hUser, "touchy_hud.lbl_0")
    local h1 = hud.getComponent(hUser, "touchy_hud.lbl_1")
    local h2 = hud.getComponent(hUser, "touchy_hud.lbl_2")
    local h3 = hud.getComponent(hUser, "touchy_hud.lbl_3")
    local h4 = hud.getComponent(hUser, "touchy_hud.lbl_4")
   
   if(nTaps0 > 0) then
        hud.setComponentPosition(h0, 50 * ( nX0 + 1 ), 50 * ( nY0 + 1 ))
    else
        hud.setComponentPosition(h0, 150, 150)
    end
   
   if(nTaps1 > 0) then
        hud.setComponentPosition(h1, 50 * ( nX1 + 1 ), 50 * ( nY1 + 1 ))
    else
        hud.setComponentPosition(h1, 150, 150)
    end
   
   if(nTaps2 > 0) then
        hud.setComponentPosition(h2, 50 * ( nX2 + 1 ), 50 * ( nY2 + 1 ))
    else
        hud.setComponentPosition(h2, 150, 150)
    end
   
   if(nTaps3 > 0) then
        hud.setComponentPosition(h3, 50 * ( nX3 + 1 ), 50 * ( nY3 + 1 ))
    else
        hud.setComponentPosition(h3, 150, 150)
    end
   
   if(nTaps4 > 0) then
        hud.setComponentPosition(h4, 50 * ( nX4 + 1 ), 50 * ( nY4 + 1 ))
    else
        hud.setComponentPosition(h4, 150, 150)
    end

end


but i only get two labels moving about as i touch

i've only had a cursory look at the iPhoneJoypadEmulation sample (hence the coord conversion)

can anyone explain to me the inside track, maybe it's my phone and it only handles 2 touches? or is there something more to know?

merci

It could just be the phone.

I spent awhile on the same problem awhile back, to then just decide to test on my iPhone and all 4 worked.

With an Android Motorola Atrix I figured it was pretty powerful and would support 4 touch, which it doesn't apparently.

Although I also remember reading a few months back Apple won a lawsuit against google in that they won by prooving they had invented multi-touch and that all Android Devices had to get rid of multi-touch although no clue how that turned out in the end.

Best bet is to search for your phone and see if it supports 4x touch.
