negative mouseposition values ?
May 7^th, 2007, 11:11pm

hello,

is it possible to get negative values for mouseX() and mouseY() once the mouse moves out of the active window ?
it's just that coming from lingo & director i used that a lot and i kind of miss it...

so when the mouse goes to the left, in director you get values getting less even if the mouse is moving beyond the left border of the window. (movement: starts at 100, goes to 0, more left would be -100, -200 etc.)

any ideas ?

all the best

lia.-

Code:


void setMouseXY()  
{
  if(mouseX>=0 && mouseX<width && mouseY>=0 && mouseY<height) return;
  Point mouse, winloc;
  mouse = MouseInfo.getPointerInfo().getLocation();
  winloc = frame.getLocation();
  if(!frame.isUndecorated()){
    winloc.x += 3;
    winloc.y += 29;
  }
  mouseX = mouse.x-winloc.x;
  mouseY = mouse.y-winloc.y;
}

hi yonas,

thanks for your answer, but something doesn't work, i tried importing the core, cause it got some error "no field named "mouse" was found....., however there is an accessible field "mouseEventMethods" whose name closely matches the name "mouse" .....

what would i need to do to be able to use mouse, winloc and Point in processing?

-----------------------------------

import processing.core.*;

void setup(){
size(400,400);
background(255);
}

void draw(){
setMouseXY();
println(mouseX);

}

void setMouseXY()
{

// your code here ...
}

-----------------------------------

all the best

This works fine for me..
Removed the if-sentence, it was causing problems Tongue

Hope it works for you as well

Code:


import processing.core.*;
   
void setup(){
size(400,400);
background(255);
}
 
 
void draw(){
  setMouseXY();
  println(mouseX);
}
 
 
void setMouseXY()  
{
  Point mouse, winloc;
  mouse = MouseInfo.getPointerInfo().getLocation();
  winloc = frame.getLocation();
  if(!frame.isUndecorated()){
    winloc.x += 3;
    winloc.y += 29;
  }
  mouseX = mouse.x-winloc.x;
  mouseY = mouse.y-winloc.y;
}

Reply #4 - May 9^th, 2007, 10:01pm hi, i am still getting this: No accessible field named "MouseInfo" was found in type "Temporary_3310_3773". my java version (mac osX): java version "1.5.0_06" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-112) Java HotSpot(TM) Client VM (build 1.5.0_06-64, mixed mode, sharing) all the best lia.-

JohnG Ex Member	Re: negative mouseposition values ? Reply #5 - May 9^th, 2007, 10:22pm That's very odd, since MouseInfo is a variable, not a field.. i sounds like your code doesn't quite match the code psoted, since I don't see how you could get that error, from the example code.

JohnG Ex Member	Re: negative mouseposition values ? Reply #9 - May 9^th, 2007, 11:01pm I don't know what else to suggest to be honest. However, if you're writing in processing, you don't need the "import processing.core.*" line, processing does some munging behind the scenes to add such things.
