我使用物理主体,类别位掩码和SKPhysics联系人制作了联系人识别器。不幸的是它不起作用。你能以某种方式帮我找错吗? 此代码不打印语句Touched。
是因为一个主体是SKSpriteNode还是第二个SKShapeNode?我们可以识别SpriteNode和ShapeNode之间的联系吗?
我做了所有的改进,比如@giorashc用SKPhysics身体说,但没有奏效。
import Foundation
import SpriteKit
import GameplayKit
import UIKit
var TouchLevel3BadgeChecker = 0
enum BodyType:UInt32{
case TheCircle = 1
case TheEightBack = 2
}
class TouchLevel3SceneClass: SKScene, SKPhysicsContactDelegate{
var Eight = SKSpriteNode(imageNamed: "8.png")
var EightBack = SKSpriteNode(imageNamed: "8Back.png")
var counter : Int = 0;
override func didMove(to view: SKView) {
self.physicsWorld.contactDelegate = self
Eight.position = CGPoint(x: 0, y: -50)
Eight.name = "Eight"
addChild(Eight)
EightBack.position = CGPoint(x: 0, y: -50)
EightBack.name = "EightBack"
EightBack.zPosition = 2
EightBack.physicsBody? = SKPhysicsBody(texture: EightBack.texture!,
size: EightBack.texture!.size())
EightBack.physicsBody?.usesPreciseCollisionDetection = true
EightBack.physicsBody?.isDynamic = true
EightBack.physicsBody?.affectedByGravity = false
EightBack.physicsBody?.categoryBitMask = BodyType.TheEightBack.rawValue
addChild(EightBack)
Circle.position = CGPoint(x: 0, y: -25)
Circle.zPosition = 2;
Circle.fillColor = SKColor.black;
Circle.name = "Circle"
Circle.physicsBody? = SKPhysicsBody(circleOfRadius: 30)
Circle.physicsBody?.usesPreciseCollisionDetection = true
Circle.physicsBody?.isDynamic = true
Circle.physicsBody?.affectedByGravity = false
Circle.physicsBody?.categoryBitMask = BodyType.TheCircle.rawValue
Circle.physicsBody?.collisionBitMask = BodyType.TheEightBack.rawValue
Circle.physicsBody?.contactTestBitMask = BodyType.TheEightBack.rawValue
addChild(Circle)
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
for t in touches{
let location = t.location(in: self);
if atPoint(location).name == "Circle"{
Circle.position.x = location.x
Circle.position.y = location.y
}
}
}
func didBegin(_ contact: SKPhysicsContact) {
if contact.bodyA.categoryBitMask == BodyType.TheCircle.rawValue && contact.bodyB.categoryBitMask == BodyType.TheEightBack.rawValue{
print("Touched")
} else if contact.bodyB.categoryBitMask == BodyType.TheCircle.rawValue && contact.bodyA.categoryBitMask == BodyType.TheEightBack.rawValue{
print("Touched")
}
}
}
答案 0 :(得分:0)
您没有创建physicsBody
属性。由于其可选和零设置,其属性不会做任何事情。
使用:
创建physicsBody
属性
EightBack.physicsBody = SKPhysicsBody(...);
Circle.physicsBody = SKPhysicsBody(...);
