README - QTSprites

This sample code creates three sprite movies. In the first, an icon moves from left to right,

and changes its image at the halfway point. In the second, a picture is gradually changed

from fully transparent to fully opaque. The third movie is more complicated; in it,

the sprite track contains three sprites: a space ship, an icon, and a

world. Optionally, the track also contains a fourth sprite, a background

picture. The space ship and icon move about as the sprite movie plays.

See the file QTSprites.c for further details.

This sample code also shows how to test for mouse clicks ("hits") on a

sprite. Open a movie containing a sprite track and then click on a sprite;

its visibility state is toggled between visible and invisible. 

For Windows builds using Microsoft Visual C++, the Makefile (QTSprites.mak)

automatically calls Rez to create the resource file QTSprites.qtr from the

input file QTSprites.r. The .qtr file must reside in the same directory as the

application QTSprites.exe. For final delivery of your product, you should

insert the .qtr file into the .exe file by using the tool RezWack.

Enjoy,
