flash cc createjs hittest works without hit

[tanvira5454192]

the rect should be alpha=0.1 once the circle touches the rect . but if statement not working . it becomes 0.1 opacity without hitting

/* js

var circle = new lib.mycircle();

stage.addChild(circle);

var rect = new lib.myrect();

stage.addChild(rect);

rect.x=200;

rect.y=300;

circle.addEventListener('mousedown', downF);

function downF(e) {

stage.addEventListener('stagemousemove', moveF);

stage.addEventListener('stagemouseup', upF);

};

function upF(e) {

stage.removeAllEventListeners();

}

function moveF(e) {

circle.x = stage.mouseX;

circle.y = stage.mouseY;

}

if(circle.hitTest(rect))

{

  rect.alpha = 0.1;

}

stage.update();

*/

you're only executing that hittest once, when that code executes.

ie, move the hittest inside moveF

[tanvira5454192]

moving hittest inside moveF causes a bit better

but same problem .when i start move it goes opacity 0.1 .

i need not to touch rectangle

i have uploaded the file in my server for better understanding

easeljs hittest checks a hit between an object and a point.  read the docs: EaselJS Tutorial: Using hitTest

Don't use hitTest. Use getObjectsUnderPoint, pass the circle's x/y coordinate, and check if the rectangle is in the returned list.

now its working fine

var p = rect.localToLocal(0, 0, circle);
if (rect.hitTest(p.x, p.y)) {
  rect.alpha = 0.1;
} else {
  rect.alpha = 1;


}

you're doing what i suggested.

[tanvira5454192]

you are our teacher . so its normal

you have 205313 points where i have only 10 .

i think 205313 >10

that's a good way to not get help in the future, should the need arise.  good luck.
