- Tail gradient effect (performance is affected, but it's cool!).
- Different star images.
- 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.
- Different- size particles.
- Other minor issues and bug fixes.
- Load and save simulations to XML files.
- Fixed crash in prefs screen.
- Added extra friction mode.
- Small performance tweak.
- Copy protection removed.
- Friction! Particles can be set now to have friction so they will eventually stop.
- Tails do not show for particles in rest.
- Performance tweaks.
- 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.
- Fixed bug with static particles and elastic collisions.
- Spelling mistake corrected (thanks Connor for reporting).
- 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.
- Added accelerometer support, lost in v3.1.3.
- The app can now be moved to SD card.
- 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.
- 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.
- 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).
- About page redesigned.
- Simulation only restarted when needed (if prefs were changed).
- 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.
- 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.
- Fixed bug that prevented simulation to run properly in merger collisions mode (thanks to Neil for reporting).
- Some minor performance improvements.
- Fixed bugs that force closed the app since last performance update.
- Performance improved, should run better now, specially on slower devices.
- Name changed.
- Orientation set to portrait.
- 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.
- Fixed bug where collision effects seemed to emerge from black hole (thanks to Nick for reporting).
