B basil99 Active Member Licensed User Longtime User Feb 26, 2013 #1 Lets say, I load several images and add them to Gameview in this way Dim gv as GameView and gv.BitmapsData.Add( Picture1 ) gv.BitmapsData.Add( Picture2 ) gv.BitmapsData.Add( Picture3 ) gv.BitmapsData.Add( Picture4 ) ....... gv.BitmapsData.Add( PictureN ) Then I need to "clear" Gameview and start to draw another pack of pictures: gv.BitmapsData.Add( anotherPicture1 ) gv.BitmapsData.Add( anotherPicture2 ) gv.BitmapsData.Add( anotherPicture3 ) ....... gv.BitmapsData.Add( anotherPictureM ) So, questions are: 1) how to "clear" GameView "in one click" ? If possible ? 2) If not, I need to make calls like that: Picture1.Delete = True Picture2.Delete = True Picture3.Delete = True ................ PictureN.Delete = True then add another group of pictures ? I tried this but by some reason I can't add picture to the gameview again if it was deleted before - nothing is displayed 3) How to remove picture from gameview list without deleting it ? Thank you Last edited: Feb 26, 2013

It doesn't "destroy" the image. It is convenient to set Delete to true and not modify the list directly. Modifying the list directly can lead to parent For Next blocks to fail. Upvote 0

Juan Luis Lopez Member Licensed User Longtime User Mar 5, 2014 #7 but bitmapdata hasnt an alpha property... i found a way to do that after deleting with bitmapdata.delete=true, i have to reload a bitmap and add it to the gameview list. i have been reading about accelerated surface and dxlib but i found it hard. thanks!

Your bitmapdata has a bitmap property containing the image to make blink. Use the AlterColors function of my Accelerated Surface library (or any similar function of another library) to change the alpha value. EDIT: another way is to draw with a zero size destrect if the library allows that (untested). That's not ideal but it's better than creating/removing an object repeatedly. Upvote 0
