SOLVED: Saving an entire loop's worth of rotated sprites using dynamic sprites

[antipus]

I realize that this is a lot like WHAM's post about Dynamic sprites, because that's how I got to the point that I'm at now, where I'm stuck.

Here's my problem. I'm trying to take an entire series of animated sprites (in this case, a fireball), and rotate them so the player can cast the fireball in any direction, instead of just the 8 standard ones. It's not too hard to get this to work with one sprite, but I can't use iterative code to do all seven animation frames.

The following code works (I've got rotatedMissile defined globally)...

Code: AGS

ViewFrame *oldFrame = Game.GetViewFrame(VBOLTFLY, 8, 0);
rotatedMissile = DynamicSprite.CreateFromExistingSprite(5513, true);
rotatedMissile.Rotate(30);
oldFrame.Graphic = rotatedMissile.Graphic;

But when I try to do stuff like this, it rotates the final sprite and fills the rest with cups...

Code: AGS

int rotateFrame = 0;
while(rotateFrame < 7){
  rotatedMissile = DynamicSprite.CreateFromExistingSprite(5513 + rotateFrame, true);
  rotatedMissile.Rotate(30);
  ViewFrame *oldFrame = Game.GetViewFrame(VBOLTFLY, 8, rotateFrame);
  oldFrame.Graphic = rotatedMissile.Graphic;
  rotateFrame++;
}

Having not used Dynamic Sprites much, I get the feeling that the problem is that I've got one sprite, and I can't possibly use that same sprite for seven different frames. However, I can't bear the thought of creating 7 different global dynamic sprites and assigning them manually. Especially because there are a lot of other things that are supposed to fly through the air at a rotated angle while animating (enemy spells), possibly at the same time. And then I'd need a whole bunch more, all of which would have to be manually assigned.

Is there any way around this? Can I get an array of Dynamic sprites, for instance? I tried "DynamicSprite *rotatedMissile[7]" and it crashed. =) Or can I get the Dynamic Sprites to save to the frame more permanently, so I can reuse the Dynamic Sprite without it clearing the graphic in the loop?

Creating an array of DynamicSprites is the way to go.

This should work:

Code: ags

DynamicSprite*rotatedMissile[7];
int rotateFrame = 0;
while(rotateFrame < 7){
  rotatedMissile[rotateFrame] = DynamicSprite.CreateFromExistingSprite(5513 + rotateFrame, true);
  rotatedMissile[rotateFrame].Rotate((rotateFrame+1)*45);
  ViewFrame *oldFrame = Game.GetViewFrame(VBOLTFLY, 8, rotateFrame);
  oldFrame.Graphic = rotatedMissile[rotateFrame].Graphic;
  rotateFrame++;
}

Where did you declare the array? You have to do it outside any function for it to work.

Gracious sakes. Sorry for taking your time. Yes, that worked perfectly. Thanks, Khris!

My stupid mistake was changing DynamicSprite *rotatedMissile to DynamicSprite *rotatedMissile[7] WITHOUT changing other parts of the code. The game kept shooting back an error that I couldn't "assign value to entire array" and I thought the problem was that I couldn't MAKE an array of those. Nay, not so. It's just that I couldn't say rotatedMissile = DynamicSprite.CreateFromExistingSprite(5513, true) once I had turned it into an array.

For anyone out there reading this, this would is a sweet way to rotate larger things, like walkcycles. Now I'm waiting for someone to make "Inception: The Game."

Would this really work with walkcycles? I have started doodling on a top down 360 shooter-sort-of game, but it felt like an impossible task with AGS. And I've always thought using dynamic sprites was really slow.
Could AGS really handle this? And would it perform in hi-res?
