Random Hills Generator
« on: October 27, 2019, 09:21:55 pm »
This program will create between 1 and 25 different size and shaped hills and blue sky on the screen. You can keep pressing the Space Bar to create different ones. If you want to save any of the screens to your computer as a .bmp file, press S and it will go to the Save screen where you can name it anything you want. The commands are in the Title Bar. I made it so the hills have darkness in the center and as they expand out they lighten up with a brighter green. This program can be used with other graphics programs to add text for logos or any kind of picture you wish and/or rename it to a .jpg or any other type of graphic file. Enjoy :)

Thanks :). Sure would be cool if I can figure out how to add an INPUT command anywhere on the screen someone clicks, like _PRINTSTRING can do. I guess I can try to calculate it as good as I can using LOCATE and the mouse. Does anyone know of an equation that converts graphic coordinates to LOCATE text coordinates? I'll Google it to see if there's something online. I just think it would be cool if someone can add text to this program to make logos or signs, etc.
Or I guess I could just add the INPUT above and then it uses PRINTSTRING To where the person clicks.

Locate row, col : input "Is this where you want to put the prompt? "; yesno$

Try different value for row (vertical character cells) , col ( horizontal character cells)

So where they click _mouseY/16 = row, and _mouseX/8 = column.

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(800, 600, 32)
  2.  
  5.     mx = _MOUSEX: my = _MOUSEY: mb = _MOUSEBUTTON(1)
  6.     IF mb THEN
  7.         LOCATE my / 16, mx / 8: INPUT "Is this where you want your INPUT prompts "; yes$
  8.  
  9.     END IF

I added a way to add text to it with the mouse. At first I tried a different way using _PUTIMAGE so the screen would be 100% as you left it, but for some reason I couldn't figure it out again. So instead I just put a blue box around the INPUT text when you are done with it. The only problem with that is if you add text in that same location, it will be erased if you want more after that. Oh well, it's all for fun anyway. You can also type one word and then keep moving and clicking the mouse as much as you want in as many locations as you want for that same text. I also used the POINT command to use the same color as where you clicked as the background of the text. Like if click in the sky, it will make the background text blue. If you clicked the same word(s) on the hills, it will use that certain shade of green. It's standard small text but it's OK with me.

Sorry Bplus, I just added that new version a few seconds after you tried to help me. I kind of like it this way so people can quickly click with the mouse as many times as they want for the same text. But I guess your way would fix that problem I have with not having to delete anything. I will see what I can do.

I liked your way better. This time no text is erased at all. I didn't add any of your text though, just using the LOCATE conversion math with INPUT worked perfectly. Thank you!

Here is that certain area I changed:

Code: QB64: [Select]
  2.     a$ = INKEY$
  3.     IF a$ = CHR$(27) THEN END
  4.     IF a$ = " " THEN GOTO start:
  5.     IF a$ = "s" OR a$ = "S" THEN GOTO saving:
  7.         mouseX = _MOUSEX
  8.         mouseY = _MOUSEY
  9.         mouseLeftButton = _MOUSEBUTTON(1)
  10.     LOOP
  11.     IF mouseLeftButton = -1 THEN
  12.         clr& = POINT(mouseX, mouseY)
  13.         COLOR _RGB32(0, 0, 0), clr&
  14.         LOCATE mouseY / 16, mouseX / 8
  15.         INPUT "", txt$
  16.     END IF
  18.

Those hills....

I am thinking some sort of golfing game? Maybe it's getting late ;-))

Very nice.  If you had added an audio track, some wag who likes wordplay could have commented "The Hills are Alive with the Sound of Music" and we could all have pictured Julie Andrews in Alpine garb.

LOL cool Qwerky.

Well, I completely re-wrote the program to make it more realistic looking. I went back to the old SIN and COS again to add shades of green on the sides of the hills.
The only thing I couldn't figure out is how to change the shape of the hills like I had before. I tried to add numbers to every line but I'm not sure if that itself would do the job, it might need completely different equations that I don't know of. But anyway, this is what I have so far. With this version you can't save the picture yet since I'm not finished with it. But I thought you all would like to see it. Keep pressing the Space Bar to make new random renditions.

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(800, 600, 32)
  2. again:
  4. PAINT (2, 2), _RGB32(128, 194, 255)
  5. a$ = ""
  6. seconds = 45
  7. r = 127
  8. g = 100
  9. b = 127
  11. size = INT(RND * 100)
  13. amount = INT(RND * 25) + 5
  16.     tt = RND * 90
  17.     xx = RND * 800
  18.     one:
  19.     seconds = seconds + .25
  20.     s = (60 - seconds) * 6 + (180 + tt)
  21.     x = INT(SIN(s / (180 + tt) * 3.141592) * ((180 - t) + size)) + xx
  22.     y = INT(COS(s / (180 + tt) * 3.141592) * ((180 - t) + size)) + 750
  23.     CIRCLE (x, y), 4, _RGB32(r, g, b)
  24.     PAINT (x, y), _RGB32(r, g, b)
  25.     g = g + 1
  26.     IF seconds = 75 THEN
  27.         seconds = 45
  28.         t = t + 1
  29.         IF t = (180 + size) THEN
  30.             t = 0
  31.             GOTO more:
  32.         END IF
  33.         g = 100
  34.         GOTO one:
  35.     END IF
  36.     GOTO one:
  37.     more:
  39.     size = INT(RND * 100)
  40.     m = m + 1
  41.     IF m = amount THEN EXIT DO
  43. m = 0
  45.     a$ = INKEY$
  46.     IF a$ = " " THEN GOTO again:
  47.     IF a$ = CHR$(27) THEN END
  49.

OK I added a sky that gets darker as you look higher and added the Text and Save features again. I think I'm about done, unless someone can figure out an equation to change the shape of the hills, but I'm not worried about it. Again, I don't use the CIRCLE command for these hills, I use SIN and COS in order for the shades of green to change on the sides. This program is just a tool to add more graphics to with another graphics program mostly. Or you can just enjoy the scenes. :)
