I'm currently using Metal to create a game board with floating balloons; each balloon is a SKSpriteNode with an image of a balloon attached. The user touches and drags the balloon to a second balloon, merging the two. Exactly how they get merged is based on input from the user. I have a UISegmentedControl that pops up where the user selects one of four responses and the merge occurs. Currently, the UISegmentedControl pops up in the middle of the game board; however, I would like it to overlay on top of the first balloon instead.
I have tried this once the two balloons touch each other:
bubble1.physicsBody!.velocity = CGVector(dx: 0, dy: 0) // Stopping the balloon
requestView.frame.origin.x = bubble1.position.x
requestView.frame.origin.y = bubble1.position.y
Where requestView is a UIView (with the same dimensions of the balloon) with various subviews (including the UISegmentedControl) and bubble1 is the SKSpriteNode (balloon).
However, when I add the requestView as a subview of the game board, it does not overlay on top of the SKSpriteNode (bubble1). In fact, each time I try it, it doesn't even seem to appear in the same space relative to the location of the bubble1.
Any thoughts on what I might be doing wrong?
Thanks!
In the end, I simply "recreated" a UISegmentedControl by inserting SKLabelNode that had user interaction turned on for a tap. I created a SKNode, inserted four labels for the options and attached an action to tapping each label. I then had this SKNode hidden by default and made it visible only after a user controlled collision occurred.
So, in the end, it's functional, even if I needed a little more programming to make it happen than a true UISegmentedControl.
