Flint Particle System version 0.9.4

6th March 2008

Now in SVN and download. The core features of the library haven’t changed but I have added a number of new behaviours.

• Access all properties in Actions, Initializers, Counters and Activities so they can be modified while the emitter is running.
• AlphaInit initializer sets the initial alpha value for all particles
• ImageClasses and SharedImages initializers set the particle image to one selected from a group, with weighting to adjust the selection
• MouseExplosion action pushes particles away from the mouse
• MouseGravity action pulls particles towards the mouse
• TurnAwayFromMouse action causes particles to turn away from the mouse
• GreyscaleZone uses a greyscale image to define a zone, with weighting based on the luminence of each pixel
• Pulse counter emits particles in regular bursts
• PerformanceAdjusted counter adjusts the rate of particle emission if the frame-rate drops
• TwoWay energyEasing functions have an energy peak half-way through the particle’s lifetime
