私はちょうどモバイルアプリゲームの作成を終えて、今度はゲーム内の障害物（この例では雲）を使って動きをアニメーションしようとします。助言がありますか？SpriteKitで動く障害物を作る方法
func createClouds() -> [SKSpriteNode]{
var clouds = [SKSpriteNode]();
for _ in 0 ..< 2 {
let cloud1 = SKSpriteNode(imageNamed: "Cloud 1")
cloud1.name = "1"
let cloud2 = SKSpriteNode(imageNamed: "Cloud 2")
cloud2.name = "2"
let cloud3 = SKSpriteNode(imageNamed: "Cloud 3")
cloud3.name = "3"
let darkCloud = SKSpriteNode(imageNamed: "Dark Cloud")
darkCloud.name = "Dark Cloud"
cloud1.xScale = 0.9
cloud1.yScale = 0.9
cloud2.xScale = 0.9
cloud2.yScale = 0.9
cloud3.xScale = 0.9
cloud3.yScale = 0.9
darkCloud.xScale = 0.9
darkCloud.yScale = 0.9
cloud1.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: cloud1.size.width - 5, height: cloud1.size.height - 6));
cloud1.physicsBody?.affectedByGravity = false;
cloud1.physicsBody?.restitution = 0;
cloud1.physicsBody?.categoryBitMask = ColliderType.Cloud;
cloud1.physicsBody?.collisionBitMask = ColliderType.Player;
cloud2.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: cloud2.size.width - 5, height: cloud2.size.height - 6));
cloud2.physicsBody?.affectedByGravity = false;
cloud2.physicsBody?.restitution = 0;
cloud2.physicsBody?.categoryBitMask = ColliderType.Cloud;
cloud2.physicsBody?.collisionBitMask = ColliderType.Player;
cloud3.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: cloud3.size.width - 5, height: cloud3.size.height - 6));
cloud3.physicsBody?.affectedByGravity = false;
cloud3.physicsBody?.restitution = 0;
cloud3.physicsBody?.categoryBitMask = ColliderType.Cloud;
cloud3.physicsBody?.collisionBitMask = ColliderType.Player;
darkCloud.physicsBody = SKPhysicsBody(rectangleOf: darkCloud.size)
darkCloud.physicsBody?.affectedByGravity = false;
darkCloud.physicsBody?.categoryBitMask = ColliderType.DarkCloudAndCollectables;
darkCloud.physicsBody?.collisionBitMask = ColliderType.Player;
clouds.append(cloud1)
clouds.append(cloud2)
clouds.append(cloud3)
clouds.append(darkCloud)
}
clouds = shuffle(cloudsArray: clouds);
return clouds
}
func arrangeCloudsInScene(scene: SKScene, distanceBetweenClouds: CGFloat, center: CGFloat, minX: CGFloat, maxX: CGFloat, player: Player, initialClouds: Bool) {
var clouds = createClouds()
if initialClouds{
while(clouds[0].name == "Dark Cloud") {
clouds = shuffle(cloudsArray: clouds);
}
}
var positionY = CGFloat();
if initialClouds {
positionY = center - 100;
} else {
positionY = lastCloudPositionY;
}
var random = 0;
for i in 0...clouds.count - 1 {
var randomX = CGFloat();
if random == 0 {
randomX = randomBetweenNumbers(firstNum: center + 90, secondNum: maxX);
random = 1;
} else if random == 1{
randomX = randomBetweenNumbers(firstNum: center - 90, secondNum: minX)
random = 0;
}
clouds[i].position = CGPoint(x: randomX, y: positionY);
clouds[i].zPosition = 3;
if !initialClouds {
if Int(randomBetweenNumbers(firstNum: 0, secondNum: 7)) >= 3 {
if clouds[i].name != "Dark Cloud" {
let collectable = collectableController.getCollectable();
collectable.position = CGPoint(x: clouds[i].position.x, y: clouds[i].position.y + 60);
scene.addChild(collectable);
}
}
}
必要であれば、私はより多くのコードの例を提供することができますが、私はそれが上記の例と意味のいくつかの種類を作る確信しています。あらかじめありがとうございます！
