Re: Solar System

Version 5 is now uploaded. All input is in Graphics Fields - much smoother than by Text mode. Just type in the data & hit Enter. It asks if your info is correct. If you made a mistake just enter "n" where asked. It is Paused at the requested date; hit GO to continue running from there. Copy the whol...

Re: Solar System

I find that INPUT (in Text mode) acts like that normally. I more or less solved it by some re-arrangement of the input statements and inserting some PRINT statements. (It still drops to the bottom, but nothing is hidden.) However (as I got locked out of my account until today) I decided to write tha...

Re: Solar System

I will have to look into that. Possibly inserting some Print statements will help. I’m using an external keyboard, so the problem doesn’t arise. I have modified all the DRAW settings to fit it on an iPhone and I see the input “request” drops to the bottom of the screen but doesn’t cause a problem. I...

Re: Solar System

Version 4 (now posted) allows you to go directly to a specified date without displaying all the dates "getting there". Thus it arrives at the date much faster. You enter a specific date and the program will display "Calculating" for a few seconds, then display at the date you selected. Tap "Go" to s...

Re: Solar System

Version 3 of Solar System.sb (now posted) includes a (simulated) elliptical orbit for Mercury. I add this because it is almost as elliptical as Pluto, and is apparent in the display. I have also corrected the orbit "offsets" of Mercury & Pluto so that they don't vary as you change the Zoom level. (A...

Re: Radiation Dose Map - problem!

Thank you. I've never understood (or looked into) Retina display, so had no idea my problem would be related to it. My iPad Mini shows the Screen Scale as 2. Is that Retina or Non-Retina? (I don't see it in the manual). In my program I had to multiply pixel locations by 2 to work correctly. It sound...

Re: Solar System

I have posted Version 2 of SolarSystem.sb in the original post, with the following changes that I hope are improvements: - smoother scaling, especially for the outer planets. - Stop/Go button is now a Pause/Go button. This allows adjusting of Scale & Speed while paused or stopped at a Stop Date. Go ...

Re: Solar System

Chooch912- I'm coming up 90 in 2 months, so keep on programming! If you need any explanations in Solar System I'll be happy to help. My introduction to BASIC was in the 1970's on a time-share IBM main-frame computer with input and paper output on a teletype machine, and we saved our program on (and ...

Re: Radiation Dose Map - problem!

Thank you rbytes for solving my problem. I was trying to read the screen pixel colour at specific points using GET PIXEL X,Y COLOR R,G,B,A but could not get it to work and had no idea why. I had never heard of such a thing as 4 pixels per screen location. So I just had to change my statement to GET ...

Re: Solar System

I have made a small revision to colour the Stop button red [Add: SET BUTTONS CUSTOM (near the top) and FILL COLOR 1,0,0 (where the button is created)].
