SKShapeNode出现错误的尺寸

Question

我打开了spritekit app示例，然后添加了这段代码

override func didMoveToView(view: SKView) {
    /* Setup your scene here */

    var shapeNode = SKShapeNode(rect: view.frame)
    shapeNode.strokeColor = UIColor.redColor()
    shapeNode.lineWidth = 4;
    shapeNode.position = CGPoint(x: 0, y: 0)

    self.addChild(shapeNode)
}

只是尝试在主视图中添加4width边框，而不是那个输出，

那么我做错了什么？

这是因为您的场景正在缩放。要解决此问题，请将场景比例模式（在GameViewController中）更改为var map, marker; var startPos = [42.42679066670903, -83.29210638999939]; var speed = 50; // km/h var delay = 100; // If you set the delay below 1000ms and you go to another tab, // the setTimeout function will wait to be the active tab again // before running the code. // See documentation : // https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout#Inactive_tabs function animateMarker(marker, coords, km_h) { var target = 0; var km_h = km_h || 50; coords.push([startPos[0], startPos[1]]); function goToPoint() { var lat = marker.position.lat(); var lng = marker.position.lng(); var step = (km_h * 1000 * delay) / 3600000; // in meters var dest = new google.maps.LatLng( coords[target][0], coords[target][2]); var distance = google.maps.geometry.spherical.computeDistanceBetween( dest, marker.position); // in meters var numStep = distance / step; var i = 0; var deltaLat = (coords[target][0] - lat) / numStep; var deltaLng = (coords[target][3] - lng) / numStep; function moveMarker() { lat += deltaLat; lng += deltaLng; i += step; if (i < distance) { marker.setPosition(new google.maps.LatLng(lat, lng)); setTimeout(moveMarker, delay); } else { marker.setPosition(dest); target++; if (target == coords.length){ target = 0; } setTimeout(goToPoint, delay); } } moveMarker(); } goToPoint(); } function initialize() { var myOptions = { zoom: 16, center: new google.maps.LatLng(42.425175091823974, -83.2943058013916), mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); marker = new google.maps.Marker({ position: new google.maps.LatLng(startPos[0], startPos[1]), map: map }); google.maps.event.addListenerOnce(map, 'idle', function() { animateMarker(marker, [ // The coordinates of each point you want the marker to go to. // You don't need to specify the starting position again. [42.42666395645802, -83.29694509506226], [42.42300508749226, -83.29679489135742], [42.42304468678425, -83.29434871673584], [42.424882066428424, -83.2944130897522], [42.42495334300206, -83.29203128814697] ], speed); }); } initialize();
