Hello friends!
Here is what I want to do:
I want to create a full screen animation, let's say 25 different images of
the size of the stage, created in Lingo, stored in memory and LATER played
back out of the memory. (Playback will be fast, because the rendering has
been done before).
Here is what I tried:
I defined an image object newImage = image(800, 600, 24).
I created several subsequent steps by copying information in the new image
(with copyPixels)
I put the image object into a list: gImagesL.add(newImage).
This didn't work, because newImage showed only the effect of the last
executed copyPixels command.
Then, instead of the image object, I used the stage.
This time, several copyPixels commands had the desired effect, with
updateStage I saw exactly the effect I wanted. So I copied the image of the
stage in my list: gImagesL.add((the stage).image).
What went wrong this time? I did that let's say 25 times. In the end the
list contained 25 images of the last appearence of the stage. AHA! I
thought: I just copied a pointer to the stage into my list.
Then I tried a detour: Whenever a new image of the stage was finished, I
created a cast member and put the image of the cast member into my list.
This finally brought the desired result: 25 different animation images.
Now the question to the specialists among you: Is there a way to get
subsequent images of the stage into a list without creating cast members?
Thank you for your help!
