ios - Sprite Kit 中的简单碰撞

我有两个节点。玩家和敌人。我希望 Enemy 节点在足够近后跟随 Player 节点，并且 Enemy 节点在与 Player 节点碰撞时会停止。我得到的是 Enemy 节点位于 Player 之上，两个节点都被推送。我曾想过以某种方式阻止 Enemy 节点在与 Player 发生碰撞时移动，但在我看来它应该是一种 cleaner 方式。

(我通过在更新时更改它的位置来移动敌人节点)。

这是我的 GameScene.sks:

-(void)didMoveToViewSKView *)view {

    player = [self childNodeWithName"character"];
    enemy  = [self childNodeWithName"enemy"];
    self.physicsWorld.contactDelegate = self;
}

-(void)touchesBeganNSSet *)touches withEventUIEvent *)event {

    for (UITouch *touch in touches) {
        moveToTouch = [touch locationInNode:self];
        SKNode *tile = [self nodeAtPoint:moveToTouch];
        if([tile.name isEqualToString"tile"])
        {
            moveToTouch = tile.position;
        }
    }
}

-(void)updateCFTimeInterval)currentTime {

    [self walk:player to:moveToTouch];

    if((SDistanceBetweenPoints(enemy.position, player.position) < 200))
    {
        [self walk:enemy to:player.position];
    }


}

-(void)walkSKNode*)node toCGPoint)moveTo
{
    if (CGPointEqualToPoint(moveTo, CGPointZero))
    {
        return;
    }


    if(round(moveTo.y) != round(node.position.y))
    {

        if(moveTo.y > node.position.y)
        {
            node.position = CGPointMake(node.position.x,node.position.y+2);
        }
        else if (moveTo.y < node.position.y)
        {
            node.position = CGPointMake(node.position.x,node.position.y-2);
        }

    }else if(round(moveTo.x) != round(node.position.x))
    {

        if(moveTo.x > node.position.x)
        {
            node.position = CGPointMake(node.position.x+2,node.position.y);
        }
        else if (moveTo.x < node.position.x)
        {
            node.position = CGPointMake(node.position.x-2,node.position.y);
        }

    }

    float distance = SDistanceBetweenPoints(node.position, moveTo);
    if (distance < 1.0){
        moveToTouch = CGPointZero;
    }

}

我不知道你是如何设置你的敌人跟随玩家的。 不过你可以试试

• 将敌人动态设置为 false
• 或将速度设为 0

使用碰撞检测来了解碰撞的时间。
