Collinsa

Moteur physique simulant des collisions entre formes géométriques primitives.

Compiling and running

  1. build jar using : build.bat
  2. run jar :
    • classic run : use run.bat
    • run a preset : java -jar Collinsa.jar -s globalForces

Available commands

  • Running

    • -s [preset_name] to run a preset, check EPreset for a list of available presets

  • Engine Settings : Tickrates and World size

    • --worldSize (Vec2f) size of the world on the x and y coordinates
    • --width (float) world's width in meters (overwrites worldSize)
    • --height (float) world's height in meters (overwrites worldSize)
    • --chunkCount (Vec2f) number of chunks on the x and y coordinates
    • --realtime [false|true] to define if the simulation must run in realtime or not (i.e. 1 sec IRL <=> 1 sec in simulation). requires higher fpsp rate
    • --dt (int) interval of time per timestep (if realtime = false)
    • --fpsp (int) change the refresh rates of number of simulation timestep (per sec)
    • --fpsr (int) change the refresh rates of number of images generated (per sec)
    • --fpsd (int) change the refresh rates of number of display refresh/repaint (per sec)

  • Render Settings : Aesthetics & Debug

    • --scale (float) to set the rendering scale in px/m
    • --forceScale (float) to set the force rendering scale in px/N
    • --showAABB [false|true] to enable the display of the entities' axis aligned bounding boxes
    • --showAxes [false|true] to display the x and y axes
    • --showChunks [false|true] to display the chunks' bounds
    • --showWorldBounds [false|true] to display the world's boundaries
    • --showForces [false|true] to display forces -- --wireframe [false|true] to turn wireframe display (shapes not filled) on or off
    • --aabbColor (Color) to change their color (e.g. : --aabbColor BLUE)
    • --chunkColor (Color) to change their color (works like aabbColor)
    • --worldBoundsColor (Color) to change their color (works like aabbColor)
    • --bgColor (Color) to change the background's color (works like aabbColor)
    • --useDebugColor [false|true] to display use collision-related colors (AABB collision / confirmed collision / etc.)

  • Formatting :

    • Color : field name from java.awt.Color or rgb(red,green,blue)
    • Vec2f : Vec2f(x,y) or vec2f(x,y)
    • int : 1, 2, 3, etc.
    • float : 1f, 2.13f, etc.
    • double : 1d, 1.0, 2.13d, etc.
    • boolean : true or false
