A path defines the motion of a visible player, such as a sprite, and can be a line, a circle, or a simple Bezier curve. A button functions much like a regular Windows push button, radio button or check box but uses user-defined images to represent its different states. A text player displays text and has specifiable font and color properties. A box displays a color-filled rectangle. An effect is used to transition between screens.
Common effects are wipes, dissolve, and zoom.
A score player is much like a musical score. It lets you control multiple objects actions over time and can be used, for example, to animate an object across the screen two seconds after a button is pushed. An audiostream plays a RealAudio URL, which is great if you want to add streamed speech or music. A sublet, which has already been mentioned, allows mbedlets to be embedded inside of mbedlets. Packaging Other than the Web browser, mBED Interactor comes with everything you'll need to create multimedia applications.
