public static bool IsWithinRadius(Vector3 referencePoint, Vector3 gameObjectPosition, float radius) { float distance = Vector3.Distance(referencePoint, gameObjectPosition); return (distance <= radius); }Example 1: In a tower defense game, the IsWithinRadius method can be used to check if an enemy is within range of a tower's attack. The reference point would be the tower's position, the game object position would be the enemy's position, and the radius would be the tower's attack range. Example 2: In a racing game, the IsWithinRadius method can be used to detect if a player's car is within a certain range of a power-up. The reference point would be the power-up's position, the game object position would be the player's car position, and the radius would be the range within which the power-up can affect the car. The package/library that GameLiving IsWithinRadius could belong to is likely a game development library or framework, such as Unity or Unreal Engine.
