multitouch bug on iPhone 6 and 6 plus, build 2550 and 2562

Solar2D Daily Builds and Public Releases
#1

From what I can determine this was introduced in a recent daily build.  I noticed this on 2550, so then attempted the latest build 2562

Basically when multitouch is enabled, event.xStart and event.yStart are 0 when event.phase is “ended”

When you remove multitouch, xStart and yStart correctly reflect the touch start position

this only happens on device on the iPhone 6 and 6 plus, although it may be on other devices I haven’t tested.

Does not happen in the Corona simulator, iOS simulator (8.1), iPads (various from 7 to 8.1.3)

also does not happen on any android devices or the android simulator

[lua]

system.activate( “multitouch” )

local box = display.newRect(display.contentCenterX,display.contentCenterY,100,100)

local p = display.newText(   

  {  text = “touch the square”,     

    x = 150,

    y = 100,

    width = 300,    

    font = native.systemFontBold,   

    fontSize = 14

  }

  )

function btouch( e )

  p.text  = "phase: " … e.phase … ", xStart: " … e.xStart … ", x: " … e.x … ", yStart: " … e.yStart … ", y: " … e.y

end

box:setFillColor(1,0,0)

box:addEventListener(“touch”,btouch)

[/lua]

i can confirm this doesn’t happen in build 2448, which was the last build we used to submit apps before upgrading to a version that supported 64bit

Hi @derek14,

Thanks for diagnosing and testing this. Can you please file a bug report so we have it properly logged in our tracking system? I think you can probably just use one of our multitouch sample projects, or if you have a really simple one that you made, that’s fine too.

Thanks,

Brent

Please make sure to include a build.settings and config.lua with your submission.

Thanks Brent and Rob, I’ve submitted a bug report and attached a very simple test project to demonstrate it.   We have had users report this bug on 2 of our apps now, but most of our apps are unaffected as they were built using an older build of corona.  Unfortunately I can’t roll back to that build for the affected apps because of the new 64bit requirements.

#6

Guys, this bug also happens on build 2545. Note that this is the only build available to Basic and Starter subscribers that supports 64-bit iOS. This means that any brand-new apps that we publish will be crippled.

Is there a form of some sort where we can vote for the urgent fixing of this? Our project has a non-negotiable deadline and this is a deal-breaker.

#7

Hi @orlin,

This issue is fixed in builds 2565 and later, but I understand the 64-bit and tier level “snafu” in your case. I will need to ask the engineers if this could be rolled into the 2545 build for Starter/Basic users.

Thanks,

Brent
