Space Explorer v.1 - Space Car Running

This section provides a tutorial example on how to use ActionScript 3 statement blocks in SWFC script file to build my Space Explorer - Version 1: the space car is running!

Let's try to build a simple Flash animation with the use of ActionScript 3.0 statement blocks in a SWFC script file:

Here is Space Explorer Version 1, space_explorer_1.sc:

#- space_explorer_1.sc
#- Copyright (c) 2014 by Dr. Herong Yang, herongyang.com
#
.flash bbox=400x400 background=#000044 fps=12
.circle space_car r=6 line=8 color=#cccccc fill=#ff0000

.frame 1
   .put space_car
   .action:
      _root.x_pos = 6;
      _root.y_pos = 6;
      _root.x_speed = 1.0;
      _root.y_speed = 0.5;
      _x = _root.x_pos;
      _y = _root.y_pos;
   .end

.frame 2
   .action:
      _root.x_pos += _root.x_speed;
      _root.y_pos += _root.y_speed;
      _x = _root.x_pos;
      _y = _root.y_pos;
   .end
   
.frame 3
   .action:
      gotoFrame(1); // index=0 is for frame 1
      play();
   .end

.end

Note that the argument value of function gotoFrame(n) is zero based. gotoFrame(1) is equivalent to "Go to frame 2".

Compile space_explorer_1.sc and generate the HTML code:

C:\herong>\local\SWFTools\swfc.exe space_explorer_1.sc 
   -o space_explorer_1.swf

C:\herong>\local\SWFTools\swfdump.exe -E space_explorer_1.swf
   > space_explorer_1.html

Open space_explorer_1.html in a Web browser. You will see that my space car is running correctly with a constant speed!

If you are reading the Web version of this book, you will see the Flash running here. Otherwise, you will see a static image.
