animate with millis()
Mar 11th, 2008, 12:06pm  
hi,
i try to code an oldschool filmcount with the use of the millis() function. the problem is that the numbers for the count are displayed in completely different intervals.
is it because the programm is too slow, or did i make some mistake in my code ???

thanx for every answer

import processing.candy.*;
import processing.xml.*;

SVG[] numbers;
String svgName;

int x = 0;
int y,y1;

int fileName = 1;
int letterBox = 67;
int svgCount = 9;


void setup(){
 size(1024,768);
 //frameRate(100);
 smooth();
 numbers = new SVG[10];
 for(int i=0;i<10;i++){
   svgName = "nr" + fileName + ".svg";
   fileName++;
   numbers[i] = new SVG(this,svgName);
   numbers[i].drawMode(CENTER);
   numbers[i].ignoreStyles();
 }
   
}

void draw(){
 smooth();
 background(190);  
 
 y = 0;
 y1 = height - letterBox;
 
 noStroke();
 fill(0);
 rectMode(CORNER);
 rect(x,y,width,letterBox);
 rect(x,y1,width,letterBox);

 
 noFill();
 stroke(255);
 strokeWeight(10);
 ellipse(width/2,height/2,550,550);
 strokeWeight(4);
 ellipse(width/2,height/2,500,500);
 
 
 noStroke();
 fill(255);  
 numbers[svgCount].draw(width/2,height/2);
 int s = millis();
 if(s%1000 == 0){
   svgCount--;
 }
   
 stroke(0);
 strokeWeight(1);
 line(0,height/2,width,height/2);
 line(width/2,0,width/2,height);
 
}

millis() might just not return values as 1000, if it hits on 999 or 1001 the counter wont decrease.
you should use some other method to check for a timehit..


void setup()
{
 startTime = millis();
}


void draw()
{
 timer = millis() - startTime;
 if( timer >= 1000 )
 {
   count --;

   startTime = millis();
 }
}

that should work
