Raylib Physics simulator

This a physics simulator containing hardbody collisions, springs, effectors, and gravity. Play around with it and have fun. One each grid square is 1 by 1.

Controls

• Left click outside menu: spawn body/circle
• Left click on menu: adjust parameters
• Tab: hides menu
• Spacebar: pause physics
• Shift +Left click: spawn effector
• ctrl+left click: spawn circle every frame(fps frame, not physics frame)
• ctrl+shift + left click: spawn effector every frame(same as above)
  
• start right click over a body, and still holding right click: selects that body
• selected body + ctrl: provides a spring between the body and your cursor
• selected body, stop holding right click over another body: adds a spring between the two bodies
• Q: Sets all bodies (except for static) positions to center of the screen
• W:Sets all velocities to 0
• C: Frame buffer is not cleared out, solitaire win effect
• Esc: closes the application

Menu definitions

Word or value in parenthesis is the default value for the parameter 

• Body
  • Body type
    • Dynamic(default): body behaves normally
    • Kinematic: body only responds to collisions
    • Static: body doesn't not respond to anything and never moves
  • Radius(.5): the radius of new bodies
  • Mass(1): the mass of new bodies
  • Gravity(1): how much world gravity affects this body. Can be negative
  • Bounce(.9): how much energy is saved when collision occurs
  • Damping(.1): how quickly the body loses energy over time
  • Velocity(4): the magnitude of the initial velocity the body spawns in with
• Spring
  • Stiffness(15): how much flexibility/give(or lack thereof) the spring has
  • Damping(.1): how quickly the spring loses energy over time
  • Length(2): the resting length of the spring
    • Auto Length(true): if on, when making a spring, the current distance between the bodies is the spring resting distance, If off, then Length is used instead.
• Effector(all only affect bodies inside their radius)
  • Effector type
    • Gravitation(default): bodies attract other bodies, does not override world gravity
    • Point: bodies are attracted to the center of the effector
    • Area: bodies are pushed in the direction of angle
    • Drag: slows bodies down
      
  • Size(1.5) : the radius of the effector
  • Force(10): how strong the effector is
  • Angle(0): what direction Area pushes; 0 is right,90 is up, 180 is left 270 is down
• FPS(60): how many physics frames happen per second. The more, the more accurate the simulation and vise versa
• Gravity(-9.81): the world gravity that is applied to all bodies
• Spring X(1): multiplier on all spring strength (excluding cursor)
• Simulate(true): Whether the physics are ruining or not. Can also be toggled with spacebar
