* raylib [physac] physics example - Basic rigidbody
*
* Welcome to raylib!
*
* To test examples, just press F6 and execute raylib_compile_execute script
* Note that compiled executable is placed in the same folder as .c file
*
* You can find all basic examples on C:\raylib\raylib\examples folder or
* raylib official webpage: www.raylib.com
*
* Enjoy using raylib. :)
*
* This example has been created using raylib 1.3 (www.raylib.com)
* This example has been created using raylib 1.4 (www.raylib.com)
