In this example, the target rotation is passed in as a user-friendly Euler Angle (the Vector 3 angle you’re used to seeing in the Unity inspector). However, it ‘s possible to deal with native Quaternions instead. Simply use a Transform reference as the target variable and pass in its direct rotation value.

Mar 18, 2023 · In modern graph theory terms the trick is to determine if every node has the same in-degree as its out-degree. If they are equal, then every time the path reaches a node there must be an unused edge available to leave it. Euler's insight allows an algorithm to be designed to find the Euler circuit, if it exists, that is almost trivial. Algorithm:
