Unity 2018 Cookbook - Third Edition

The CalculateBlipPositionAndDrawBlip (...) method

This method inputs three parameters: the position of the player, the position of the target, and a reference to the prefab of the blip to be drawn.

Three steps are now required to get the blip for this object to appear on the radar:

1. The normalized position of the target is calculated by calling NormalizedPosition(...)
2. The position of the blip on the radar is calculated from this normalized position by calling CalculateBlipPosition(...)
3. The RawImage blip is displayed by calling DrawBlip(...) and passing the blip position and the reference to the RawImage prefab that is to be created there
