Removed

• Points were calculated and plotted for nothing, they have been removed

Note

• The project is going to be put on hold for a while, and there may be some small updates for simple bug fixes, but no new features will be added.

Changed

• Fixed a shortcut key bug: pressing the space key will no longer click on the last button selected
• Categorizing objects
• Changed the way sound is handled on impact, issue #21
• From now on, when a word is not translated, the term ‘Not yet translated’ will be used instead

Removed

• Removed the simulate() function, which was never used for anything other than adding lag
• Removal of the Coulomb constant ($K$), which was no longer useful as it was expressed with other constants defined in the simulation.
• Removal of collision test and electromagnetic force presets
