问题 Im trying to learn C# with Unity engine But a basic script like this: using UnityEngine; using System.Collections; public class scriptBall : MonoBehaviour { // Use this for initialization void Start () { Rigidbody.AddForce(0,1000f,0); } // Update is called once per frame void Update () { } } gives this error: Assets/Scripts/scriptBall.cs(8,27): error CS0120: An object reference is required to access non-static member `UnityEngine.Rigidbody.AddForce(UnityEngine.Vector3, UnityEngine.ForceMode)'

问题 We've moved from fabric.io to Firebase and everything seems to be ok except one thing. We're using Unity 2019.2.6 , target platform is iOS , target architecture is " Universal ". For dSYMs uploading I pack dSYMs folder from *.xcarchive to dSYMs.zip and upload it to Firebase via the following code ./upload-symbols -gsp <path_to_plist>/GoogleService-Info.plist -p ios <path_to_dSYMs.zip>/dSYMs.zip As a result I see the following lines in my terminal: Successfully submitted symbols for

问题 Is there a way to find inactive gameObjects with a tag? There are answers saying no its not possible but that was in 2013.

GameObject.FindGameObjectsWithTag - Manual: Returns a list of active GameObjects tagged tag.

问题 For example, you might use something like: public Vector3 Inertia = new Vector3(); void Update() { Inertia += transform.TransformDirection(Vector3.forward) * Input.GetAxis("Thrust") ; transform.Translate(Inertia * Time.deltaTime); } If you want fly a spaceship in a 3D space with all degrees of freedom. Inertia keeps track of momentum in world space while the controls add to it along the axes of the players orientation. But, now I want to check what the players speed is along his current

问题 I developed a game years ago and now decided to improve the game and started to download the unity again. after upgrading Unity I figured out Unity doesn't know all JS files and has detached them from objects. any solution that fixes the problem and adds JS support to Unity again? 回答1: August 2017 All the way back to Unity 1.0, the Unity game engine has supported a version of JavaScript called UnityScript. Today on the Unity blog, Unity have announced that they will no longer be supporting

问题 I'm working in Unity, but this is really just a C# question so I hope this is the right section to post this. Anyways, I still have trouble visualizing the execution of scripts in my head, especially when there are more than one running and they all have different functions. It's gotten more complicated recently as I've added Update, FixedUpdate, and Coroutine to my list of "When's this running"? Update and Fixed Update I get the gist. As for Coroutine, I basically understand it's a type of
