#8bitsnow

There’s a fun challenge on Twitter at the moment with the hashtag #8bit snow. They want people to make little demos on their 8bit computer for Christmas and post it to Twitter with this hashtag. I whipped up something quickly in Z88dk today.

#8bitsnow on VZ200 & VZ300

I used my FOXGLOVZ library for the proportional font text and programmed some snow to fall above it. The code is below if you’re interested.

#include <games.h>
#include <vz.h>
#include <stdlib.h>
#include <string.h>
#include <balloc.h> 
#include <sys/ioctl.h>
#include "foxglovz.c"

int main(void)
{
	#asm
	di
	#endasm
	// Set graphics MODE(1)
	int mode = 1;
	console_ioctl(IOCTL_GENCON_SET_MODE, &mode);

	struct myfontspecs myfont;
	strcpy(myfont.name, "SansSerif5x9p");
	myfont.xpos = 0;
	myfont.ypos = 0;
	myfont.spacing = 1;
	myfont.colour = _vzred;
	myfont.ypos = 5;
	myfont.fx = _fxnormal;
	myfont.ypos = 33;	
	fox_textat(&myfont,"Merry Christmas from");
	myfont.ypos = 43;
	fox_textat(&myfont,"@WauloK of BlueBilby.com");
	myfont.ypos = 53;
	fox_textat(&myfont,"VZ200&VZ300 computers");
	
	int snowx[100],snowy[100],i,t;
	for(i=0;i<100;i++) {
		snowx[i]=rand()%127;snowy[i]=rand()%30;
	}
	
	while(1) {
	for(i=0;i<100;i++) {
			textcolor(3);
			plot(snowx[i],snowy[i]);
	}
	msleep(50);
	for(i=0;i<100;i++) {
		unplot(snowx[i],snowy[i]);
		snowx[i]+=rand()%3-1;
		snowy[i]++;
		if (snowx[i] < 0) snowx[i]=0;
		if (snowx[i] > 127) snowx[i]=127;
		if (snowy[i] > 32) { snowy[i]=0; snowx[i]=rand()%127; }
		}		
		
	}

while(1) {}
}
