mouse coord and drawing a line
Feb 17th, 2010, 1:52pm  
Hi, i want/need for a project mouse-coord (mouse.x)., but how can i use them (instead of pmouse...) to draw a line?

Maybe someone can show me right way?!
Thanx for reading and thinking about.


import processing.opengl.*;

Point mouse;
int mX, mY;

void setmousexy(){
 mouse = MouseInfo.getPointerInfo().getLocation();
 mX = mouse.x;
 mY = mouse.y;
}


void setup() {
 size(screen.width, screen.height, OPENGL);
 background(255);
 noStroke();
}  

void draw() {
 setmousexy();

 stroke(0, 0, 0, 80);
 strokeWeight(1);
 smooth();
 line (?????);
}

what about this :

void setup() {
 size(640, 200);
 background(0);
}

void draw() {
 stroke(255);
 if(mousePressed) {
   line(mouseX, mouseY, pmouseX, pmouseY);
 }
}

If you dont want to use vectors.

put
oldx=mouseX
oldy=mouseY

at the end of you program and then use them instead of Pmouse. I might be confused on what your asking. Do you want a totally different way to do it or are you just boycotting Pmouse for some reason?
