RawSave / Restore Screen and backgroundanimation? (solved)

[Skyhawk]

I've noticed a problem with the RawSaveScreen
and Raw Restore Screen
commands...

i'm using the new DynamicSprite functions in my repeatedly execute room-script
(player -> water reflections ....) the RawSaveScreen is located in Player enters screen and the RawRestoreScreenÃ,  in repeatedly execute....
Logically the background animation is not working...
(if i put the RawSaveScreen Command in repeatedly execute the whole reflection thing isn't working...)

is there any way to get both? reflection and animation?


Ã,  RawRestoreScreen();
Ã,  DynamicSprite* sprite = DynamicSprite.CreateFromExistingSprite(GetGameParameter(GP_FRAMEIMAGE, cEgo.View, cEgo.Loop, cEgo.Frame));
//Ã,  sprite.Resize(50,93);
Ã,  sprite.Flip(eFlipUpsideDown);
Ã,  RawDrawImageTransparent(character[EGO].x-25, character[EGO].y-1, sprite.Graphic, 50);
Ã,  sprite.Delete();

Sure. Don't RawDraw the reflection, use an object instead.

Edit: Of course this means that you can't delete the sprite until the player leaves the room. And you must set a default (non-dynamic) sprite for the object at the same time, or the game will crash the next time you enter (as it's referring to a non-existing pointer).

Edit 2: Alternately, you could animate the background "by hand" in the same repeatedly_execute_always function as the reflection script. Instead of RawRestoring, you could draw another frame on top of the existing with 0% transparency. Then you could put in a counter for the animation to decide WHICH frame should be drawn. (you may come across a crash problem when redrawing the same frame over itself - I'm not sure how to get around it). This seems like a considerably slower solution though.

hmmmm, the object method causes an error message

perhaps it is a simple mistake in the script, but i dont think so...


object[1].Visible = 1;
DynamicSprite* sprite = DynamicSprite.CreateFromExistingSprite(GetGameParameter(GP_FRAMEIMAGE, cEgo.View, cEgo.Loop, cEgo.Frame));
sprite.Resize(50,93);
sprite.Flip(eFlipUpsideDown);
object[1].Graphic = sprite.Graphic;
object[1].Transparency = 50;
object[1].SetPosition(cEgo.x, cEgo.y);




the easiest working way was a transparent character with extra sprites and a simple


cReflect.x=cEgo.x;
cReflect.y=cEgo.y+93;
cReflect.loop=cEgo.loop;
cReflect.frame=cEgo.frame;Ã, 


but i want to save sprite slots and keep the game as small as possible
eventually a additional flip function in the view editor?

This is due to this bit from the manual:

"IMPORTANT: If the DynamicSprite instance is released from memory (ie. there is no longer a DynamicSprite* variable pointing to it), then the sprite will also be removed from memory. Make sure that you keep a global variable pointer to the sprite until you are finished with it, and at that point call Delete."

It shouldn't really crash the game though, I'll add some handling for a friendlier error report.

But basically, you need to declare the
DynamicSprite* sprite;
variable at the top of the script rather than within the function, otherwise it gets deleted as soon as the function returns.
