How to detect if mouse has stopped moving?

Meowsterr

Hi, is there a piece of code for this? I've been trying to search the interwebz but found nothing.

Chrisir

not really...

you have to make it yourself

e.g.

void mouseMoved() {
    // gets called automatically
    lastTimeMouseMoved = millis(); 

}

before setup()

int lastTimeMouseMoved  = -1; 

then in draw() check how much time has past since the mouse moved the last time using

howmuchtimehaspastsincethemousemoved = millis() - lastTimeMouseMoved  ;

ok thanks

This is another way to do it. Processing remembers that previous mouse position. You can use this inside the draw () function.

if (mouseX == pmouseX && mouseY == pmouseY){
  // mouse has not moved
}

thanks...

looks simpler...

not sure if it'll work when we want to monitor a length of 0.5 secs though

quark

Where did the 0.5 seconds come from? There is no mention of time in the question?

Chrisir

never mind

just an example

sry

;-)

No problem I just got confused, if you wanted to know how long the mouse was stationary you would need to use mills() :)

Meowsterr

ah I see how you did it quark, ty.

Chrisir

mouseMoved() gets called automatically when the mouse moves
