flash cc createjs hittest works without hit

Question

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();

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 only executing that hittest once, when that code executes.ie, move the hittest inside moveF
