Swapping Image For Image Or Sprite

Games
#21

Swapping out images would be good to have mainly because that’s how it’s done in the other environments, allowing for easier migration to Corona SDK both of apps and coders :wink:

It also allows keeping all the settings of the image, including the z-index (determined by order of creation). Re-creating the image (and usually also re-inserting it into some scrollView, overlay or other parent view) would put it frontmost.

Certainly you could create a sprite frame sheet, if you have a Photoshop license or the equivalent, and that gives better performance.

But it would be one of those handy things for the one-off image swaps that don’t need performance. It might also save a bit on the GC?

try this :slight_smile:

chosen1pic = “selectCharacter.png”

chosen1 = display.newImage(chosen1pic)

        chosen1.x = display.contentWidth *.75

        chosen1.y = display.contentHeight *.75

choice1 = display.newImage(“choice1.png”)

        choice1.x = display.contentWidth /8

        choice1.y = display.contentHeight /6

local function removeImagea()

        chosen1: removeSelf()

        end

local function choicea()

        removeImage()

        chosen2pic = “AVTR1.png”

        chosen2 = display.newImage(chosen2pic)

        chosen2.x = display.contentWidth *.2

        chosen2.y = display.contentHeight *.75

        end

choice1: addEventListener(“tap”, choicea)
