Merry Christmas!

Bundle up because its snowing! This program will make you glad you are a inside a warm house. It's really simple, but fun.

I thought about adding a house, and Christmas lights but it's okay.

Turn on your favorite Christmas music, and enjoy. If you give it a while the snow will start gathering at the bottom of the screen

I've modified it a little bit to allow for a wider variaty of snowflake drift...

`create variables for the snowflakes
dim pos_y#(299)
dim pos_x#(299)
dim speed#(299)

`Each snowflake will drift at a different pace

snow# = 480

`randomly position the snowflakes above the screen so they fall down into the screen
`Modified by JP
for a = 0 to 299
   pos_y#(a) = rnd(480)-480
   pos_x#(a) = rnd(640)    `Moved by JP
   drift(a) = rnd(10)
   speed#(a) = rnd(1.0)
next a

angle# = 0
`main loop
do
cls

for a = 0 to 299
   `make snow move down
   inc pos_y#(a),speed#(a)

`create snowflake
   `make snowflake move according to drift.
   newX# = pos_x#(a) + (drift(a) * sin(angle#))
   DrawShowFlake(newX#, pos_y#(a))

`when the snowflake hits the bottom of the screen reset it at the top, and make the snow on the ground rise
   if pos_y#(a) > 480 then pos_y#(a) = 0 : pos_x#(a) = rnd(640) : dec snow#, 0.01

`drift angle
   inc angle#, speed#(a) * .025
   if angle# > 358 then angle# = 0
next a

`make snow rise as the snowflakes hit the bottom of the screen
box 0,snow#,640,480
