A nice particle simulation sandbox which can double as a cool screensaver. Controls: -Press the flag to respawn particles -Click anywhere to create a new particle with a random mass and velocity -Click on an existing particle to delete it (if you can) -Press C to clear the background (for Draws 2 and 3) -Press R to randomize Radius, Influence, Friction and Mass Range. Also changes the current mass of the particles Variables: -Amount: The number of particles generated on start (max 50 is recommended, set to 0 for a blank slate) -Radius: Distance within which particles interact -Influence: Strength and type of force applied between particles (+ for attracting, - for repulsing) -Friction: Rate at which particles slow down (0 meaning no friction and 100 corresponding to the speed diminishing by 2% per frame) -Draw: Type of visualisation (2 and 3 are laggier) 0: None 1: Linked particles are currently interacting with each other 2: Each particle is assigned a fixed trail color 3: The trail color indiactes the speed of the particles (green = slow, red = fast, blue = very fast) -Mass Range: The mass of the particles ranges from 1/M to M for M=Mass Range (1 gives all particles the same mass) -[EXPERIMENTAL] Collisions: Press to toggle wether particles bounce off of each other when their sprites overlap, or if particles are treated as singular points. Notes: -The fading effect of the background is applied more strongly every 10 seconds to make it less messy for longer simulations Some good presets: -Radius 80; Influence 6; Friction 20; Mass 5. -Radius 50; Influence 10; Friction 30; Mass 10. -Radius 200; Influence 10; Friction 100; Mass 1. -Amount 3; Radius 300; Influence 10; Friction 80; Mass 10. -Amount 4; Radius 300; Influence 10; Friction 20; Mass 10. -Amount 5; Radius 150; Influence 10; Friction 40; Mass 10.
