Changelog

v3.6 (02/01/2013)
  • Tail gradient effect (performance is affected, but it's cool!).
  • Different star images.
  • Bugfixes.
v3.5.1 (31/12/2012)
  • Fix for newer devices with no menu button. Now the menu button should appear as three dots at the bottom- right of the screen.
  • Fix clipping problem with some sprites.
  • BH picker improved.
  • Friction and gravity strength values tweaked.
v3.5 (24/12/2012)
  • Different- size particles.
  • Other minor issues and bug fixes.
v3.4 (08/07/2012)
  • Load and save simulations to XML files.
v3.3.1 (14/05/2012)
  • Fixed crash in prefs screen.
  • Added extra friction mode.
  • Small performance tweak.
  • Copy protection removed.
v3.3 (05/05/2012)
  • Friction! Particles can be set now to have friction so they will eventually stop.
  • Tails do not show for particles in rest.
  • Performance tweaks.
v3.2.4 (01/05/2012)
  • Bugfix version (thanks Keith for reporting).
  • Repel touches off in big simu area fixed.
  • Multitouch behaviour fixed.
  • Particles do not get stuck in wall ends anymore.
  • Number of walls increased from 10 to 15.
v3.2.3 (04/04/2012)
  • Velocity bar offset.
v3.2.2 (04/04/2012)
  • Fixed bug with static particles and elastic collisions.
v3.2.1 (03/04/2012)
  • Spelling mistake corrected (thanks Connor for reporting).
v3.2 (03/04/2012)
  • Added option to change the tail length (short, medium, long).
  • Gravity force can now be set to zero (no gravity).
  • Simulation can be paused using top velocity bar.
  • Initial particle size can be modified (extra small, small, medium, large, extra large).
  • Static particles can now be created using the shooting button.
v3.1.5 (31/12/2011)
  • Added accelerometer support, lost in v3.1.3.
v3.1.4 (20/12/2011)
  • The app can now be moved to SD card.
v3.1.3 (28/11/2011)
  • Accelerometer, FPS and particle tail controls are now on- screen for direct operation.
  • Moved controls used in big area mode to the left of the screen.
  • Performance tweaks.
v3.1.2 (24/11/2011)
  • Pan and Center camera buttons not available when in ‘screen simulation area’ mode.
  • Number of particles can be now set to 0, and black hole is not counted as a particle.
  • Antiparticle control has been disabled in Particle- Mesh mode, for in this mode the interactions are not between particles.
  • Bug fixes.
v3.1.1 (23/11/2011)
  • Possibility to display mesh points in simulation in PM mode.
  • Mesh density can now be changed. Set a higher value to increase accuracy (has an impact on performance).
v3.1 (22/11/2011)
  • About page redesigned.
  • Simulation only restarted when needed (if prefs were changed).
v3.0 (07/10/2011)
  • Particle- Mesh force calculator method. This method does not include particle- to- particle interactions and uses a mesh to calculate densities used later to calculate forces on particles. It runs faster than the Particle- Particle (direct) method.
  • Display grid densities as background in the Particle- Mesh mode. It creates a beautiful effect.
  • Preferences have been rearranged.
v2.6 (05/10/2011)
  • Background images. Select an image from your gallery to set it as background image in the simulation. If you do so, background colour setting is overriden. To get back to a plain color, just select the background colour option you desire.
v2.5.5 (22/09/2011)
  • Fixed bug that prevented simulation to run properly in merger collisions mode (thanks to Neil for reporting).
  • Some minor performance improvements.
v2.5.4 (19/09/2011)
  • Fixed bugs that force closed the app since last performance update.
v2.5.2 (17/09/2011)
  • Performance improved, should run better now, specially on slower devices.
  • Name changed.
v2.5.1
  • Orientation set to portrait.
v2.5
  • Repulsive particles! Two kinds of particles that are repulsive to each other can be added. Just click the particle shooter twice to add ‘anti particles’.
  • Info screen now has a wee user guide.
v2.4.3
  • Fixed bug where collision effects seemed to emerge from black hole (thanks to Nick for reporting).
v2.4.2
  • Elastic collisions.
