名称

mouseMoved()

示例
 // Move the mouse across the image // to change its value 
int value = 0;


void draw()
{  
fill(value);


rect(25, 25, 50, 50);


  } 
void mouseMoved()
{  
value = value + 5;

 
if (value > 255)
{
value = 0;


   }
  } 
描述 The mouseMoved() function is called every time the mouse moves and a mouse button is not pressed. (If a button is being pressed, mouseDragged() is called instead.)

Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.
