Red Screen of Death

I've run into bugs where the screen turns red and all the numbers turn into "1.#R". Does anybody know how to make it stop?

Dividing by zero doesn't do that. An infinite loop doesn't do that. The annoying thing is that it doesn't seem to do that consistently, so there's no simple way to check.

Perhaps it has something to do with the engine itself doing something with your function calls, like dividing by zero when calculating _EY() or _EZ() when you're facing straight up or down.

I've run into the screen turning black before and all of the numbers turning into 1.#J, but never red and 1.#R.

Do you have an example model that does it occasionally that we could see?

Unfortunately I've modified my libraries slightly, but if I remember correctly, changing

Code:

Jo={-dcog[1]*900,9.81-dcog[2]*900,-dcog[3]*900,-dqinv[1]*210000,-dqinv[2]*210000,-dqinv[3]*210000}

to

Code:

Jo={-dcog[1]*900,9.81-dcog[2]*900,-dcog[3]*900,-spin[1]*210000,-spin[2]*210000,-spin[3]*210000}

in my Fire Fly model would cause it.
