A java swing animator for parsing, interpreting, manipulating, and animating user described animations from .txt files.

Utilizes Inbetweening for computing visual properties over time.

Developed by Luke Andrews and Allen West.

• Looping animations.
• Dynamic addition/deletion of visuals.
• Basic controls: Play, Pause, Reset, etc.
• Dynamic display of animation over time via Swing JSlider scrubber.
• Live keyframe manipulation of visual size, speed, shape, color, position, etc.
• Dynamic organization controls (shape layering, layer swapping, etc.).
• Optional visual rotation support in .txt file interpretation.
• The output of described animations via SVG or .txt rendering.

We've included a compiled .jar file (SwingAnimator.jar) in the src directory. Try out the animator and its controls with the following terminal command!

• Make sure to navigate to the src folder before attempting to run the program.

• landrews$ java -jar SwingAnimator.jar -in buildingsSUPERLayered.txt -speed 50 -view edit
  

• Experiment further with the various included .txt files, and make your own!

Export your custom animation files to SVG format with the following command:

• landrews$ java -jar SwingAnimator.jar -in customAnimation.txt -speed 50 -view svg -out fileName.svg

Within a .txt file:

• To declare a new visual (rectangle or ellipse):

  • shape R rectangle
  • shape Z ellipse

• To customize visual properties (color, size, position, etc.) over time:

  • describes the motions of shape R, between two moments of animation:
    • t == tick to begin the display of this visual
    • (x,y) == x & y positions
    • (w,h) == dimensions (width & height of visual)
    • (r,g,b) == color (with values between 0 and 255)

  •             start                         end
                --------------------------    ----------------------------
                t  x   y   w  h   r   g  b    t   x   y   w  h   r   g  b
       motion R 1  200 200 50 100 255 0  0    10  200 200 50 100 255 0  0
    

• Define a visual's layer membership by prefacing its declaration with the following:

  • layer 1 (supports unlimited number of layers)

• Add rotations to individual visuals with the following specification:

  • (sT, eT) == beginning/ending tick for this rotation
  • (sR, eR) == beginning/ending radians for this rotation (0 - 359)

  •              rotation

        rotate R 01  40  00  200
