From Qt Creator's menu, access File — New File or Project. From Qt category, choose the JS File template. Call the collisions.js file. Put the following content into the document:
.pragma library
function boundingBox(object1) { var cR = object1.childrenRect; var mapped = object1.mapToItem( object1.parent, cR.x, cR.y, cR.width, cR.height); return Qt.rect(mapped.x, mapped.y, mapped.width, mapped.height);}function intersect(object1, object2) { var r1 = boundingBox(object1); var r2 = boundingBox(object2); return (r1.x <= r2.x+r2.width && // r1.left <= r2.right r2.x <= r1.x+r1.width && // r2.left <= r1.right r1.y <= r2.y+r2.height && // r1.top <= r2.bottom r2.y <= r1.y+r1.height); // r2.top <= r1.bottom}
