Why there is no color change precise every cycle?
Oct 5^th, 2009, 1:52pm

Please, try to love and solve this shifting
Why there is a shifting from the point where the color changes?
Is it an int/float problem?
I just want the color change precise every cycle.

Code:


int x;
int myStrokeColor;
int counter;

void setup(){
}

void draw(){
  background(204);
  x = x + 1;
  strokeWeight(2);
  counter = frameCount;  
  if(counter % width==0){
    myStrokeColor = int (random(111,255));
  }
  if (x < width){
    stroke(myStrokeColor);
    line(x,0,x,height);
  }
  if (x > width){
    x = 0;
  }
}

i dont get the counter, framecounter part. why dont you just do it this way. then there is no shifting

int x;
int myStrokeColor;
int counter;

void setup(){
}

void draw(){
background(204);
x = x + 1;
strokeWeight(2);

if(x % width==0){
myStrokeColor = int (random(111,255));
}
if (x < width){
stroke(myStrokeColor);
line(x,0,x,height);
}
if (x > width){
x = 0;
}
}

Re: Now how to manage word-change precise every cycle?

Thanx a lot for cleaning my code. works.
Now I like to go further and change words with different length precise at every cycle.
What I don't see is where to put the textWidth, so that the text starts at width minus textWidth and disappear not until the end of width.
When I start at width minus textWidth, the width wil not expand.
I have to expand the width?

Code:


float x;
int index;
String[] myTextFile = {"sun","sonic","summer","solution","sensibility"};
String s;
float wordWidth;

void setup(){
  size(200,100);
  textFont(createFont("",24));
}

void draw(){
  background(204);
  x = (x + 1);
  s = myTextFile[index];
  wordWidth = textWidth(s); 
  if(x % width==0){
    index = int(random(myTextFile.length));
  }
  if (x < width){
    text (myTextFile[index],x,40);
  }
  if (x  > (width + wordWidth)){
    x = 0 - wordWidth;
  }
}
