Starfield 2020 - December Version
« on: December 07, 2020, 07:40:04 pm »
I don't believe I made one of these this year, but I know we made them last year. So I took my glowing snow idea and turned them into glowing stars. I also figured out how to start them not directly in the center like I did last year. Plus I used different sizes of stars. Feel free to use this on anything, or add anything, etc. I was mostly just goofing off. :)

Edit: I just changed the name of this to Starfield 2020 - December Version because I found an older Starfield 2020 that I made back in June.

I just found out that back in June I did a different Starfield 2020,  I will rename this one to "Starfield - December Version".
If you are interested to see the old one, click the link below.

Ken can you get them to move faster as the approach the edge ie go faster and faster out from center. Plus start with stars scattered over the whole field.

Great idea B+. I just did both of those. I made a countdown in the beginning of numbers counting down to 0 until it starts, which then shows the entire screen of stars. Then I also figured out how to make the stars go faster as they got further away from the center. Last night I tried to make it speed up and slow down with the up and down arrow keys, so I figured that out too today. If you want to learn how I did the speeds, look at the sp, warp, and speed() variables. Check it out! :)

  15.     IF a$ = CHR$(0) + CHR$(80) THEN sp = sp - .0005: _TITLE "Warp: " + warp$
  16.     IF sp < 0 THEN sp = 0
  17.     IF sp > .1 THEN sp = .1
  18.     warp = (sp * 100) + 1

I was able to do away with the countdown completely by making a random location on the screen (except the very center) for every new star. There's no more circular pattern in the center and now it looks more realistic. :)

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(1000, 800, 32)
  2. DIM starx(1000), stary(1000)
  3. DIM dx(1000), dy(1000)
  4. DIM sz(1000)
  5. DIM speed(1000)
  8. _TITLE "Starfield 2020 - Dec. Version - by SierraKen - Use up and down arrow keys (or W and S keys) to control speed."
  9.  
  11.     _LIMIT 100
  12.     a$ = INKEY$
  13.     IF a$ = CHR$(27) THEN END
  14.     IF a$ = CHR$(0) + CHR$(72) OR a$ = "w" OR a$ = "W" THEN sp = sp + .0005: _TITLE "Warp: " + warp$
  15.     IF a$ = CHR$(0) + CHR$(80) OR a$ = "s" OR a$ = "S" THEN sp = sp - .0005: _TITLE "Warp: " + warp$
  16.     IF sp < 0 THEN sp = 0
  17.     IF sp > .1 THEN sp = .1
  18.     warp = (sp * 100) + 1
  19.     IF warp > 10 THEN warp = 10
  20.     warp$ = STR$(warp)
  21.     warp$ = LEFT$(warp$, 5)
  22.     stars = INT(RND * 100) + 1
  23.     IF stars > 25 THEN

:) I just added _FULLSCREEN mode off and on using the Space Bar. I did it because I'm going to try and make a YouTube video of it. Full Screen makes it show really awesome.

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(1000, 800, 32)
  2. DIM starx(1000), stary(1000)
  3. DIM dx(1000), dy(1000)

  8. _TITLE "Starfield 2020 - Dec. Ver. by SierraKen - Up and down arrow keys (or W and S keys) for speed. Space Bar switches back and forth to Full Screen. Esc to quit."
  9.  
  11.     _LIMIT 100
  12.     a$ = INKEY$
  13.     IF a$ = CHR$(27) THEN END
  14.     IF a$ = CHR$(0) + CHR$(72) OR a$ = "w" OR a$ = "W" THEN sp = sp + .0005: _TITLE "Warp: " + warp$

Here is the YouTube of it I just made. I speed up and then slow back down. The video is 1 minute and 10 seconds long.

Hi, you made it very nice. Am I guessing this is some preparation for a program to celebrate the new year?
