Blog - Snow on Switch

18th December 2021

Started a Snow-Game project on Switch.

Honestly, no idea what the aim of the game's going to be, but for those interested, here's how I do my lazily made snow effect.

Step One : Draw snow.
As big of a tile as you can, with a single little snowflake offset in the corner.

Step Two : Starfield
Draw a bog standard starfield, with rotating stars, but instead of stars, draw your snowflake image.

In GotoJSE, we can just use the Starfield function to draw it.

Symbol 0,"2__0_0_0_0_0_0_0_0_0_0_00;;0_0_0_0.;";

Starfield 0,1

If you have to code the starfield yourself, it's still incredibly easy, though a fair bit lengthier.


Symbol 0,"2__0_0_0_0_0_0_0_0_0_0_00;;0_0_0_0.;";

#CONST $STARS=100
#CONST $X=1
#CONST $Y=2
#CONST $ROTATION=3
#CONST $SPIN=4

Dim star($STARS,4)

// Initialisation
for m=0 to $STARS
	Star(m,$X)=Rnd(0,ScreenWidth())
	Star(m,$Y)=Rnd(0-32,ScreenHeight()+32)
	Star(m,$ROTATION)=Rnd(0,360)
	Star(m,$SPIN)=Rnd(0-2,2)
next

Graphics 512,512,2
Repeat
CLS

For m=0 to $STARS

// Move each "star" by a random amount, to give a fluttering effect
	Star(m,$X)=Star(m,$X)+Rnd(-1,1)
	Star(m,$Y)=Star(m,$Y)+Rnd(-0.5,1.5)

// Spin the "star" around.
	Star(m,$ROTATION)=Star(m,$ROTATION)+Star(m,$SPIN)

// Draw "star"
	SetRotation(Star(m,$ROTATION))
	DrawImage Star(m,$X),Star(m,$Y),0

// And if it reaches the bottom of the screen, bump it back up.
	if Star(m,$Y)>ScreenHeight()+32 then Star(m,$Y)=-32:Star(m,$X)=Rnd(0,ScreenWidth())
Next

Snow easy!
Now I just have to make a game to go with the snow.
Not 100% sure what that game will be, but I've drawn a white cat, and .. um.. That's as far as I got!
Guess we'll have to wait and see what game turns up.
