Hi Aurel,
As you know, I ran your planet.bas example using MicroA, which ran very well.
So I had to try it out using RCBasic and QB64... and they performed quite slowly. The only changes made to you program was the colour and circle commands. I had to increase the frame rate on QB64 to get it to run at the speed of MicroA... RCBasic's frame rate cannot be changed at the moment.
What is your secret? How can MicroA process quicker that QB64? (If you tell me I will hardly tell anyone else... lol)
Nicely done!!
Whoa! Now 'that' is a fast planet... Poor moon is working overtime just to keep up... Cool
