小编Hel*_*ius的帖子

我无法弄清楚如何阻止节点旋转.为什么allowRotation没有禁用它？
这是我描述节点的方式:

SKSpriteNode *badguy = [SKSpriteNode spriteNodeWithTexture:[self.spriteAtlas textureNamed:@"test"]];
badguy.texture.filteringMode = SKTextureFilteringNearest;
badguy.physicsBody.angularVelocity = 0;
badguy.physicsBody.allowsRotation = NO;
badguy.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(32, 32)];    
badguy.physicsBody.velocity = CGVectorMake(0, 0);
badguy.physicsBody.categoryBitMask = CollisionTypeEnemy;
badguy.physicsBody.contactTestBitMask = CollisionTypePlayer | CollisionTypeWall | CollisionTypeEnemy;
badguy.physicsBody.collisionBitMask = CollisionTypeWall | CollisionTypePlayer | CollisionTypeEnemy;
badguy.physicsBody.mass = 10000;
badguy.physicsBody.restitution = 0;
badguy.physicsBody.dynamic = YES;
badguy.zPosition = 10;

在更新时我调用此方法:

-(void)enemiesFollow
{

    [self.world enumerateChildNodesWithName:@"badGuy" usingBlock:^(SKNode * _Nonnull badGuyNode, BOOL * _Nonnull stop) {
        if((SDistanceBetweenPoints(self.player.position, badGuyNode.position) < 100)&&
           (SDistanceBetweenPoints(self.player.position, badGuyNode.position) > 32))
        { 
            SKAction * …
