Is this a bug with ImageSheets?

#1

Hi,

I load my ImageSheet like this:

[lua]

local newTongue = {};

local sheetData =
{
width = 53,
height = 10,
numFrames = 2,

– The params below are optional; used for dynamic resolution support
sheetContentWidth = 106, – width of original 1x size of entire sheet
sheetContentHeight = 10, – height of original 1x size of entire sheet
}

local sequenceData = {
{ name = “start2”, frames={ 1, 2}, time = 250, loopCount = 1 },
}

local mySheet = graphics.newImageSheet(“tongue_left.png”, sheetData );
newTongue = display.newSprite(mySheet, sequenceData)
[/lua]

and play it back like this:

[lua]
newTongue:setSequence(“start2”)
newTongue:play()
[/lua]

Problem is, sprite sheet get’s loaded but won’t animate. Unless I increase frames of the sequence data’s frames to like {1,2,1} or make loopCount to 2 or more. And if I make loopCount to 2, it won’t play the animation back 2 times, it gets played back infinitely!

My image file that I’m loading is sized at 106x10 and has two frames and each frame is 53x10.

What’s the problem?

Probably problem is highly related to loopCount because if I remove it, it works but when I put it and give it 1, it won’t.

You may think that animation is played back so fast that I can’t see but I press Ctrl+R fast and can’t see a thing. [import]uid: 206803 topic_id: 37379 reply_id: 145571[/import]

Problem was with the animation listener. I accidentally copied my listener from another class and in it I set another animation and play back. Since Corona didn’t complain about this ImageSheet not having that animation, I didn’t notice. Nothing in the terminal.

BTW, I still think there is a problem there with loopCount because with that animation listener there I still can’t get one loop out of my animation and my animation listener doesn’t stop any animation but when it’s there, I can’t get animation to be played back once. Because if it was with the animation listener, it would not work with the loopCount of 2.

[lua]

local function mySpriteListener( event )

if ( event.phase == “ended” ) then

if (event.target.sequence == “MajorChew”) then

numOfMonstersThatDoneChewing = numOfMonstersThatDoneChewing + 1

end

local thisSprite = event.target --“event.target” references the sprite
thisSprite:setSequence( “idle” ) --switch to “fastRun” sequence
thisSprite:play() --play the new sequence; it won’t play automatically!
end

end
