Saving player drawing to variable and using it later?

[kxait]

Hey. I'm making a game (something new...) and I want the player to be able to draw his own player image. I know they can draw penises and other stuff like that but I want to give the player freedom, anyway. How can I get the player drawing to save to a variable (ImageData perhaps?) and then drawing it to the screen? Like a normal image? I know how to make a 2d array and then modify the different parts of the array to edit the picture, then draw it based on the array, but how can I save it to a variable and then use it like a normal image? Hope this isn't too too confusing. Thanks in advance!

You can have the player draw to a Canvas.
Then when you want to save the data to a file, you can get the ImageData from the canvas and save it to a file with the encode function:

Code: Select all

local data = canvas:getImageData()
data:encode("drawing.png")

You can then load this drawing as any other image like you need it.
