Lava Lamp
« on: December 13, 2019, 02:14:33 am »
I've wanted to make one of these since I was a kid, and finally did it. It's not exactly like a lava lamp in that there's no movement inside of it. But the lava forms up and up as it gets hotter and hotter and then it forms down and down when it cools off. Then all of the lava fades out and starts over again. :) Just something I threw together tonight. I also added a fade in and out brightness of the glass border. I know the details could be better, etc. so I might work on that a bit later. But for now, what do you think of it?

Note: There's a much better one after this one with movement.

This morning I made a MUCH better one with movement of lava randomly going up and down and changing shape. The speed is also random. It doesn't make any formations like the last one, but I like this one better. I also changed the shape of the window so it's 100% lava lamp. :) Do you like it? I also learned on this one that we can make the graphic "trail" effect with any background color, I thought we were just stuck with black. lol

Note: If you have photosensitivity problems, I deleted this one so go to the next one. The next one is better anyway for everyone.

Because of photosensitivity to some of the public out there, I decided to change it so it doesn't flash as much and each lava keeps the same shape but does change sizes as it goes up or down. I actually have a better liking to this one anyway. This one has the moving lava.

Note: There is even a better one after this one, with an added bubble and some lava on each end.

I am reminded of my lava experiments in 2015 with SmallBASIC...

lets see how long to get a translation. :)

Ken you might like this.

I added a smaller lava bubble. So now I got a blob and a bubble. I also added lava stuck on the top and the bottom to show where they come from.

Note: The one after this has randomly stretched lava cords from the blob to where the blob came from.

Sorry for so many posts, but I keep making this thing better. :)
This time I removed the unnecessary PUT's and SCREEN's, etc. and just kept with the one SCREEN. I was experimenting with it earlier to see if I needed it but I don't.
This time I also made the lava cord thickness depending on the size of the blob and when the blob changes size, the cord does too. So it kinda has a stretching effect to it.

Note: One error in this one, fixed version is after this one.

Dang sorry again, I left out 1 line to make tt = 0. lol

Here's the fix:

Code: QB64: [Select]
  1. _TITLE "Lava"
  2. DIM x(1000), y(1000), d(1000), speed(1000), xx(1000), yy(1000), speed2(1000), d2(1000), cord(1000)
  3. SCREEN _NEWIMAGE(200, 600, 32)

  5. LINE (0, 2)-(198, 598), _RGB32(127, 127, 150), B

  14.     IF d(t) = 2 THEN y(t) = 10
  15.     IF d(t) = 1 THEN y(t) = 590
  16.     speed(t) = (RND * 2) + 1
  18.     x(t) = RND * 190
  19.     s = RND * 2.5
  21.     cord(t) = (RND * 480) + 120
  22.  
  23.     'Bubbles Setup
  24.     tt = tt + 1
  25.     IF tt > 800 THEN tt = 0

Pretty neat bplus, I thought about using PAINT to fill things sorta like that, but I never got around to it. Yours turns your entire monitor into one. :)
