Help on event.target inside of a table.

helloworld2013d · July 16, 2013, 10:02pm

I have a function that remove an object

function killNote (event) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local object = event.target &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;display.remove(object) &nbsp;&nbsp; &nbsp;return true end

And a displayed image that I add an event listener

local trebleClef = display.newImageRect("images/trebleClef.png", 71, 182) &nbsp;&nbsp; &nbsp;group:insert ( trebleClef ) &nbsp;&nbsp; &nbsp;trebleClef.x = centerX - 450 &nbsp;&nbsp; &nbsp;trebleClef.y = centerY - 183 &nbsp;&nbsp; &nbsp;trebleClef:addEventListener("tap", killNote)

And it works perfect, if I tap the image it’s gone!

I want to do the same idea, but I have a ‘for’ loop where I created 5 images

And I just don’t know where or how I have to add the event listener I think it’s like this

but id doesn’t work

local quarterNoteTable = {} &nbsp;&nbsp; &nbsp;local indexNote = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;for row = 1, 5 do &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--for column = 1, 2 do &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;indexNote = indexNote + 1 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quarterNoteUp = display.newImageRect("images/quarterNoteUp.png", 38, 101) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quarterNoteUp.x = (row \* 200) - 20 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quarterNoteUp.y = 206 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--whiteKey.y = column \* 104 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quarterNoteTable[indexNote] = quarterNoteUp &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;group:insert ( quarterNoteTable[indexNote] ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(quarterNoteUp[indexNote], {time=1000, x=(row \* 100) - 20, y=206}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quarterNoteUp[indexNote]:addEventListener("tap", killNote) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end

Thanks for all your help

it looks like your last lines should be:

 -- quarterNoteTable, not quarterNoteUp transition.to(quarterNoteTable[indexNote], {time=1000, x=(row \* 100) - 20, y=206}) quarterNoteTable[indexNote]:addEventListener("tap", killNote)
