aah Thankyou for explaining that to me Ive allways wanted to know how to do it

It opens as a blank empty scene for me :C I have no idea why. and with the frequency controls, you need a space on either side of the equals. e.g.

sim.frequency = 600

Awesome I noticed the B M X and the G A Y hahaha

This is incredible man, true genius

I think you mabe need to revise this, it explodes when i use it

Excelleng works well
