Which format has highest compression index in flash:

  1. Png

  2. Jpeg

  3. Bmp

  4. Gif
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Among the listed formats, PNG typically has the highest compression efficiency in Flash, especially for images with large areas of solid color or vector-like graphics. Flash's PNG compression is very effective for web graphics. JPEG uses lossy compression, BMP is uncompressed, and GIF is limited to 256 colors, making PNG superior for many Flash applications.

What will happen if I delete ".as" file after publishing

  1. Swf will run perfectly

  2. Swf will not run

  3. Swf will run but with an error

  4. Flash will generate a new .as file
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When you publish a Flash movie, the ActionScript code (.as files) is compiled into the SWF file. The SWF is a standalone file that contains all necessary bytecode and assets, so it runs perfectly without the original .as files. The source files are only needed during development and for recompilation if you want to make changes.

Difference between "_root" and "_level0", if 1.swf is loaded on 2.swf

  1. _level0 will be same for both

  2. _root will be same for both

  3. _level0 will be different for both

  4. None of them
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Flash ActionScript, _level0 always refers to the main movie timeline at level 0 of the Flash Player, regardless of which SWF you're in. The _root property, however, is relative to each SWF's own main timeline. When 1.swf is loaded into 2.swf, _root in 1.swf refers to 1.swf's timeline, while _level0 remains the same global reference for both.

I can use removeMovieClip only if:

  1. Movie Clip is dynamically attached

  2. Movie Clip is physically laying on the root

  3. Movie Clip is on _level0 only

  4. Movie Clip is empty
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In ActionScript, the removeMovieClip() function only works on movie clip instances that were created dynamically at runtime (e.g., using attachMovie or duplicateMovieClip). Author-time timeline instances cannot be directly removed this way.
