[Question] Animation using an image sequence

[sss]

Hi,

I have an image sequence of 80 frames - each frame is a JPG file of about 90 to 120 KB. As I want to keep them external, Active object cannot be used. I can't use an AVI file, so an animation object is also ruled out.
The only other idea I could think of is using the Active Picture object:
1. At start of Frame: Set Alterable Value A to 1

2.
Alterable Value A <80
Every 00"15 (15/100th of the second), new picture (Appdrive$+appdir$+"sampleanim\anim100"+str$(Alter able Value A of Active Picture)+".jpg"

The above works, but I can't get a good frame rate. I can achieve a frame rate of only about 13-20, where as when I use an Active object with speed 100, i can get a frame rate of 50 fps (my application is set at a max fps of 50).

Is there any other way of doing this, while retaining a good frame rate?

Active objects in MMF2 have a Load Frame action. Look under Animation actions.

You may need to get the latest build (246).

That takes a long time to load frames into an object, looong loads.

Thanks, I didn't knew about 'Load Frame' until you mentioned.
But I am having difficulties using this as I can't see anything happening. Probably because I am not correctly using the following:
What is 'Load Frame'? It says the value must be between 1 and 16, but I can't figure out what this means.
'Enter Frame to display(First frame is number 0' : is this the frame number to which I wish to load the frame, or does it do something else?

BTW, as Benicle has mentioned, does it really take long time to load frames? If so, how much time?

When you say to load a frame from a file, it will ask a lot of questions. Frame 0 is the first frame, 1 is the second etc... I don't think there's a limit, just a sensible size for load times...

One object loaded like this is unlikely to be a big loading hit, but several different ones all loading images may be.

I'll check how to actually load one exactly later, I can't get to MMF2 right now.

the Active object now loads the frames correctly, but there are two problems I am currently facing:
1. After an animation ends, when I do a 'change animation' action, and force animation frame to go to X (no matter what the frame number is), the animation doesn't start. I have explored everything, but I can't seem to make the animation to start again, after it ends, unless I have a 'loop' checkbox checked (or repeat X times) in the setup window.
Am I doing something wrong here?
2. After the active object is loaded with frames, when I try to destroy the object, the object gets destroyed but the memory doesn't get freed. The only way I could make it to work is to load a small bitmap file iteratively into all frames, and then destroy the object, so as to free the memory. As the active object itself takes over 100 MB of memory, it is absolutely essential for me to destroy object and free up the memory in runtime.

I am using the latest build of the MMF2 #246.

1. Restore animation frame.

[sss]

I don't see anything happening after doing Restore Animation frame. The animation is still stopped.
Is restore animation action alone is sufficient or is there anything else to do?

Thanks, that works!
However, is there any solution to the memory problem addressed above in my post, after destroying an active object in runtime?
