Dynamic Sprite as inventory graphic <solved>

[abstauber]

Hi there,

I wonder, if it's possible to dynamically modify the look of an inventory graphic.

My code is something like this

Code: ags

  // the Item's called iBlueCup
  DynamicSprite  *invItem = DynamicSprite.CreateFromExistingSprite (517, true);
  DrawingSurface *spriteSurface = invItem.GetDrawingSurface();

  spriteSurface.DrawPixel(4, 4);
  spriteSurface.Release();

  iBlueCup.Graphic = invItem.Graphic;
  
  player.AddInventory(iBlueCup);

Unfortunately AGS crashes as soon as I add the item with the custom graphic.

Here's the output:
---------------------------
Illegal exception
---------------------------
An exception 0xC0000005 occurred in ACWIN.EXE at EIP = 0x004038E8 ; program pointer is +379, ACI version 3.12.1074, gtags (1,8)

AGS cannot continue, this exception was fatal. Please note down the numbers above, remember what you were doing at the time and post the details on the AGS Technical Forum.

Thanks for your help!

Yeah, it should be possible. You need to keep a global pointer to the DynamicSprite though, or it will be destroyed as soon as the function finishes. Where do you define the DynamicSprite, inside or outside your function?

Ahh right, that did the trick   

I forgot about the global pointer and defined the sprite inside the function, 'doh!

Thanks a million!
