QUESTION

Unity 3'nd Person Controller Camera Acting Weird

Asked 2022-Apr-08 at 23:22

I'm very new in Unity and Stackowerflow. If i did something wrong, please don't judge me ^^ I used Unity's TPS Controller asset for my game. In first, it worked very well. But then It broke. But i didn't do anything :( (i don't even touch scripts or prefabs). After that, i deleted asset and re-download it but it didnt work again. Here is one example from my broken scene and these are the codes from my controller. Thanks For Any Kind of Help.

I had the same problem too. I researched a lot of documents about that and finally, I solved this problem. The problem is not about your codes or events or smth else. The problem is related to Unity. I don't know the exact reason for the problem but you can solve it this way: First, go Edit > Project Settings and select Input System Package from the Left tab. And then, change the Update Method with Process Events In Dynamic Update. And that's all! Dynamic update means the usual Update method that you see in the scripts void Update().
