- "Create a sample SwiftUI based iOS project in XCode that uses the Combine framework for updating a grid of hexagons in a SpriteKit scene every 250 milliseconds. The main view could be called LobbyView. It would display a button that presents a GameView that represents the main game UI."
- "Now lets add a button to HexagonScene that, when clicked, will stop or start the animation (disable/enable the timer)"
- Style the button as beige color and a non-bold font.
- Next, add code so that when clicking inside a hexagon, that hexagon gets a 5 pixel black outline.
- Make it a 5 pixel outline instead.
- Make the highlight persist across animation updates and toggle off when clicked again. And re-draw that outlined hexagon again after the whole grid is drawn, so it will not be obscured by nearby hexagons.
- Multiple hexagons to be selectable. Add a glowing effect on selected hexagons.
- Allow dragging to select multiple hexagons in a swipe gesture.
Here’s an updated HexagonScene.swift that allows dragging a finger across the screen to select multiple hexagons with a swipe gesture:
✅ What’s New:
- touchesMoved: as your finger moves, hexagons under the touch point are added to the selection.
- No duplicates — previously selected hexes remain.
- Still supports individual toggling via taps.
- Still has glow + 5-pixel outline on selected hexes.
- Deselect all hexagons after the drag, but before adding the new selection and rendering.
👆 You can now: Drag: select a new group (replaces previous selection). Tap: toggle one hex on/off.
You can't see it in the static screen shot, but it is updating with random colors once per second.
