test image with if statement

Solar2D Lua Language
#1

Hi, I just started learning this today but i cant find the answer to this. I was wondering if there is any way to test to see which image is associated with the variable. for example i have a local variable named pic and that image changes when the user presses a button. thing is i have 2 buttons that will change the same image to 2 different images and i each image is supposed to do something different. is there something i can put inside an if statement like

if (pic.file("circle.png")) do something else if (pic.file("cross.png")) do something else end

any help will be appreciated.

You could quite easily add a line when changing the image, eg;

picName = “pic1”

For the first picture, or if changing to 2 do 2, etc. [import]uid: 52491 topic_id: 23220 reply_id: 92952[/import]

The only problem is that i have 9 of those images and would like to figure out how to do that with unknown number of pics. I am just starting to learn and figured I should start with something simple like a tic tac toe game but from what i see it is not THAT simple lol anyone has a good tic tac toe tutorial? so far this is what i have but it ends the game randomly… sometimes even on the first click =/

[code]_H = display.contentHeight

button22.y = _H /2
button22.state = “blank”
local button21 = display.newImage( “blank.png” )
button21.x = button22.x -100
button21.y = button22.y
button21.state = “blank”
local button23 = display.newImage( “blank.png” )

Sprite sheet may be better for this, then.

In either case if you want people to assist with that much code you may want to upload a zip or post plug and play so people can actually run it. (They don’t have your images, obviously.)
