Need help adding new entry to table

local w = display.contentWidth local h = display.contentHeight local background local playBlackSqr = {} local playRedSqr = {} --------------------------------------------------------------------------------- --displaySquares --------------------------------------------------------------------------------- local function displaySquares(params) local color,alpha = params.color, params.alpha local squares = {} for i = 1,19 do squares[i] = display.newRect(100, i\*50, 25, 25) squares[i]:setFillColor(color[1],color[2],color[3]) squares[i].alpha = alpha end return squares end --------------------------------------------------------------------------------- --startAnimations --------------------------------------------------------------------------------- local function startAnimations(blackSqr, redSqr) local startBlackSqr = {} local startRedSqr = {} for i = 1,19 do startBlackSqr[i] = transition.dissolve(blackSqr[i],redSqr[i],200,i\*700-500) startRedSqr[i] = transition.dissolve(redSqr[i],blackSqr[i],400,i\*700+1300) print(#startBlackSqr .. " #startBlackSqr " .. i) print(#startRedSqr .. " #startRedSqr " .. i) end return startBlackSqr, startRedSqr end -------------------------------------------------------------------------------- --background background = display.newRect( 0, 0, w, h ) background.color = { 255, 255, 255 } --squares blackSqr= displaySquares{color={0,0,0},alpha=1} redSqr= displaySquares{color={0,255,0},alpha=0} --startAnimations playBlackSqr, playRedSqr = startAnimations( blackSqr, redSqr )

When I run this it gives no errors but also fails to add new entries to the arrays startBlackSqr and startRedSqr on lines 30 and 31:

startBlackSqr[i] = transition.dissolve(blackSqr[i],redSqr[i],200,i*700-500)

startRedSqr[i] = transition.dissolve(redSqr[i],blackSqr[i],400,i*700+1300)

TIA for your help.

That’s because the Convenience methods do not return a reference (always returns nil).

You’d need to use transition.to() on your objects to get a reference.

For a list of Convenience methods see docs here:

http://docs.coronalabs.com/api/library/transition/index.html

Unfortunately the Convenience methods do not support tag names. However pause() and resume() (without arguments) should work to pause and resume all active transitions created with these methods.

Perfect.  Thank you!
