GrabSprite and #PB_Sprite_AlphaBlending flag.

[SPH]

Hi,

I'm creating sprites using the GrabSprite instruction.

Code: Select all

For u=1 To 8
  GrabSprite(u,74,4+(u-1)*taille_y,taille_x,taille_y)
Next

But PB6.30 requires me to use the #PB_Sprite_AlphaBlending flag.

[21 :09 :33] [ERREUR] DisplayTransparentSprite(): A sprite should be created with the flag #PB_Sprite_AlphaBlending to use this command.

How do I use it with a grab?

I use that but it,s not ok :

Code: Select all

GrabSprite(u,74,4+(u-1)*taille_y,taille_x,taille_y, #PB_Sprite_AlphaBlending)

The screen has no transparency channel to grab though. Drawing an image then grabbing it to sprite can be replaced. You can draw the image part to a newly created sprite directly (instead of the screen), or just load the whole as a single sprite atlas, and use clipsprite to get your individual sprite from it.

GrabSprite(u,74,4+(u-1)*taille_y,taille_x,taille_y, #PB_Sprite_AlphaBlending)

Thank you... but the sprite is invisible (transparent?)
