so i started making a drawing program on anctionscript 3 and my coding skills are extremely basic. i know event listners and variables and children and stuff and i've made some simple projects like the snake game and a very unfinished horrendous version of 2d minecraft.

However i want to make so whatever i draw replaces what was in that area before rather than just adding on top because that makes it start to mag after a while. (i can't share the file because it's on my laptop which my mom is using) the only problem being i don't know how to do that. and i also want to know how to store the information so i can make different frames that load that information. please please please tell me how.

    Hi.

     

    Please make sure you're calling the clear method from the Graphics class appropriately or that you're not adding new instances of your drawings unnecessarily in each frame.

     

    This example may give you an idea:

    yeahh im still not exactly sure how to do that.  I'm using the moveTo() lineTo() method but it seems your project just creates a whole bunch of individual spots that mask the image but it's very laggy that's what i'm trying to avoid. i also want to know how to ACTUALLY erase

    using code:

     

    create a movieclip 

    add to stage

    apply drawing code to that movieclip.

     

    when you want to clear the drawing:

     

    remove the movieclip from the stage

    null the movieclip
