    Animating Bitmaps

    Cin Possible

      Hi, It's better to animate vectors, but sometime, I need to animiate Bitmaps.

      The problem is that animated bitmap-ojbects feel very bad. It's not smooth in movement.

      For example, I want a flower (bitmap) to spin around itself. When animating, the flower feels serrated.

      So what is the solution for that?

      Thank you!

          If the image is in the library, right click it and select the Properties option.  In the Properties interface make sure the Allow Smoothing option is selected.  See if that helps.

            The greater the number of different pixels that you have to move, the more complex the animation. So the more complex the animation, the greater the amount of work the computer has to do. When you animate in Flash, you are showing the change in the object to be animated from one frame to the next.

             

            Animation is change over time. This means that you have two variables to work with: time and distance. The two most recent versions of Flash, CC and CS6, have the frame rate set at 30 fps. Earlier versions used 15 fps. I have no idea why it was changed. In any case, you can play with the frame rate of your animation to see if the frame rate will smooth out your animation. Alternately, you can lengthen or shorten the number frames that are used for your animation to see if this will alter the quality of the animation.

             

            The frame rate and the length of the animation are not interchangeable. Fast frame rate over a long frame animation is not the same as a slow frame rate over a short frame animation. With some experimentation, you will usually be able to find a combination that you are pleased with.

             

            The quality of your artwork also plays a part in the quality of the animation. Good clear sharp images will usually animate better than a blurry image. Small images are easier to animate than large images.

              and here's another option if none of the above works - it would work perfectly for what you want: blitting.

               

              unfortunately, that's not easy for new flash users.  so, if anything above works, you should use it instead.

                The good news is that if you want to try blitting, there's code that does exactly what you want (takes a bitmap and creates a series of rotated bitmaps, storing them in a doubly linked list) here http://flexdiary.blogspot.com/2009/12/riadventure-inspiration.html
