问题 In old versions of Unity Component's renderer had material, now UnityEngine.Renderer has material, but Component.renderer doesn't have. How can I change the color of my object? private Transform myTransform; ... private void changeColor() { myTransform.renderer.**material**.color = Color.red; // renderer doesn't have *material* } 回答1: By this thread, try GetComponent<Renderer>().material.color = Color.black; 来源： https://stackoverflow.com/questions/33007575/unity3d-how-to-change-transforms

问题 The material added to the UI Panel is working in the editor window but not working in android build. How to fix this? Editor Screenshot Android screenshot Note: I have tried adding a shader to "always Included shader" list in the project setting menu. still not fixed. I'm not altering the shader/material in the code. This is worked fine in a previous unity version. (my unity version is 2018.3.11f1) The same material works fine in other game objects (like a cube, etc,.), but not works with any

问题 I have an UI image that is parented to a RectTransform container, which is parented to a UI panel, which is parented to a Canvas. I want to be able to move this UI image to the center of the screen (ie. canvas) while leaving the parenting hierarchy. My goal is to animate the UI image from the center to where it is now. Can you please let me know what this code would look like? 回答1: To answer your original question, you can place the UICell at the center of the screen using: private

问题 I have a question about the way how to show simple 2d image on top of detected marker. I have followed some tutorial to show 3d model and it works fine. there is no problem with 3d. The problem starts when I want to add normal 2d object->sprite . When I add simple sprite I can't add texture and when I insert UI image it's added together with canvas and it is not showed when target is detected. The original image on editor is placed then so far that it's difficult to find it. I would be

问题 I'm needing to have some funcitonality ignored, if I have happen to touch my UI. However, I am struggling to detect if I am actually touching it or not. My UI makes use of the native UI inside Unity. My thought behind it was to simply check the layers and if I touched anything on that layer, I'd stop any functionality from happening. So I wrote this to test it: void Update () { if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Began) { Ray ray = Camera.main.ScreenPointToRay(

问题 Simple question, I am trying to making a flappy bird clone and I need help displaying score. I have the score being added and displayed to the console, but I cant get it to show on a gui text. I've tried to google how to do this and watch a lot of people's flappy bird tutorials to see how they did it, but all them are before unity 4.6 when they introduced the new ui system, and the same code they use does not seem to work. So how can I access my gui text that is attached to my game object in

问题 I have like 10 buttons on my UI and I gotta check which one was touched. I was using the following logic and it was working fine, but now I am getting this error for some reason: NullReferenceException: Object reference not set to an instance of an object DetectButton.Start () (at Assets/Scripts/DetectButton.cs:14) Any ideas what could be going on? Here is my code (attached to the canvas), and I am using Unity version 5.1.0f3. If you need any other info I will gladly provide, thanks in

问题 My goal was to create a Scroll Rect on a worldspace canvas but whenever I would mask out the content everything vanished. I tested on an overlay canvas to see if I was setting it up correctly and I was. What I learned was that non-UI gameobject renderers were being used as the mask too so if there was something being rendered in world space, it would mask the Scroll Rect Content. The top image shows the mask disabled. The bottom shows the mask enabled. Any ideas how I can have it ignore the
