On trigger stay 2d. I’m using OnTriggerStay2D with FixedUpdate to build a list of objects in the cup each frame. The Vector Lerp is connected to SetWorldLocation. Using a list especially which is what I would like to do would have a performance impact, not sure if it would really matter though, but still we are dealing with the iPhone here. Trigger events are sent to disabled MonoBehaviours to allow enabling Behaviours in response to collisions. But since OnTriggerStay is called during FixedUpdate I would 🌍 Get my Complete Courses! https://unitycodemonkey. gameObject.
