i am wondering about the possible ways to (inadvertendly) set a private variable to -1.#IND (undefined, i presume). i've got some simple TimeDelta-related math in a project, and it occasionally results in objects becoming invisible when their angle property is being calculated as -1.#IND
since the math is really simple, i've got no idea where to start looking. does somebody know the possible causes of this error?
( the cap is here. click & drag to scratch. occasionally bugs out, especially in debug mode & with unlimited framerate )
