We need to tell the player when they've scored a goal. We can make a UI Canvas to display it with the following steps:
- With BoxballGame selected in the Hierarchy, create a new UI | Canvas, named GoalCanvas.
- Set its Render Mode to World Space.
- For its Rect Transform, set Scale to (0.02, 0.02, 0.02).
- And Anchors: Min (0,5, 0.5), Max (0.5, 0.5) and Pivot (0.5, 0.5).
- Then Position (0, 4, 0), Width/Height: (100, 50).
- Set the Canvas Scaler Dynamic Pixels Per Unit to 4, to give the text some higher resolution.
The Canvas gets a child Panel, which in turn gets a child Text element.
- Add a child of GoalCanvas, create a UI | Panel, named GoalPanel.
- Set its Source Image to None (doughnut-icon | None).
- Set Color to white with no transparency ...
