【實用休閒app】Particle Physics|最夯免費app-綠色工廠好玩App

Quick Description:

Simple particle physics game (my first game). Particles get attracted towards the gravity well and collide fluently with blocks around its environment.

- Particles can be created by dragging your finger across the screen.

- Gravity wells can be created by double tapping the screen.

- Blow up all the particles by long pressing the screen.

- Swipe the screen up or down to pause.

- Swipe the screen right or left to slow the particles down.

Future:

This app will be later upgrade to provide 3D particle collision.

Some Physics Background:

Each of the particles simply have their x and y velocities and a mass of 1 unit. The gravity wells attraction is calculated using inverse root of the velocities of each particle using one round of Newton’s method. The velocity vectors are then converted back into their x and y components.
