OK, Makslane,
Taking into account your last remarks, I may stay on the present solution (even if it is a little bit long, but I am hard at work
).
May I ask you for eventual improvements on GE (which is already an EXCELLENT dev. tool) ? Of course, I understand that you cannot take into account all users remarks, but... (Just tell me if these modifs could be implemented and, if yes, when approximatively?):
1. make the "animation finish" event work with "1 frame" actors (i.e. actors made from a single file: as I told you before, it seems that the script "view.x = view.x + 240" only works with multiple animations): this would allow me to implement your solution on my 900 actors (1 per picture), and would help me in increasing the game speed.
2. As for clones, would it be possible to have replication / array tools when creating new actors and new regions.
There are also other features which could interest the whole community (and not only my project):
3. Undo function.
4. correction of a random bug: GE freezes sometimes, when loading a new game.
5. Changing the FPS rate within the game (in live).
Many thanks Makslane!
