Coin Magnet
Part of the Unity Scripting Basics section of Coddy's Unity journey. Lesson 81 of 85.
The player walks around a field with five coins on it, carrying a magnet. A coin that comes within the magnet's range flies toward the player, and a coin that reaches the player is collected and counted. Coins farther away stay where they are until the player comes near them.
Write the whole game in one script, Magnet, on the player.
