pixi-movieclip-speed v0.0.1

pixi-movieclip-speed

Dynamically adjust PIXI movieclip(s) animation speed based on current browser's fps rate.

When PIXI movieclip animation speed is set in the range between 0 and 1, it is assumed that your browser always runs at 60fps. Imagine the sprite sheet animation is exported at 24fps and animation speed is set to 0.4 (24/60) but your browser is currently running at only 30fps. In this case, the movieclip animation will visually run slower, so the animation needs to speed it up to compensate lower browser's fps rate.

Install

npm install pixi-movieclip-speed --save

Usage

var pixiMovieclipSpeedHandler = require('pixi-movieclip-speed');

var mc = new PIXI.MovieClip(pixiTexture);
  
// the movieclip needs to run at 24fps
pixiMovieclipSpeedHandler.addClip(mc, 24);

// start the loop engine
pixiMovieclipSpeedHandler.start();

mc.play();

...
 
// remove the movieclip from the loop
mc.stop();
pixiMovieclipSpeedHandler.removeClip(mc);

...

// stop the loop engine when it's not needed anymore
pixiMovieclipSpeedHandler.stop();
