如何在Unity中更改游戏对象的纹理? [英] How to change texture of game object in Unity?

问题描述

我正在为学校项目开发Unity，并且正在使用Kinect识别面部表情.它显示的默认"表情为中性，并且随着我将表情更改为开心"或惊讶"等而改变.

I'm working on Unity for a School Project and I am using Kinect to recognize facial expressions. The "default" expression it shows is Neutral and it changes as I change facial expression to Happy or Suprised, etc.

我创建了一个名为Face的游戏对象，在其中设置了不同的纹理(PC根据我的表情显示的面孔)，并且我希望他在更改面部表情时进行更改.但是由于某种原因，它无法正常工作.

I created a game object called Face where I set the different textures (faces that the PC shows in response to my expression) and I wanted him to change when I change my facial expression. But for some reason it is not working.

我正在使用C#，首先我要设置它:

I am using C# and first I set this:

public static Texture[] textures = new Texture[7];
public Texture neutral, smiling, happy, angry, sad, kissing, surprised;
public GameObject Face;
public Renderer rend;

在开始时我有这个:

    Face = GameObject.Find ("Face");

    textures[0] = neutral;
    textures[1] = smiling;
    textures[2] = happy;
    textures[3] = angry;
    textures[4] = sad;
    textures[5] = sad;
    textures[6] = surprised;

顺便说一句，它没有找到Face，所以我由检查员将其放置在这里，并且对纹理/面部进行了相同的处理. 然后在更新中，我将其定义如下:

By the way, it didn't find Face so I put it there by the inspector and I did the same with the textures/faces. Then in the Update I put this which is defined below:

    ClassifyAndApply(numbers);


private void SaveAnimUnits()
    {
        numbers[0] = _animUnits.LipRaiser;
        numbers[1] = _animUnits.JawLowerer;
        numbers[2] = _animUnits.LipStretcher;
        numbers[3] = _animUnits.BrowLowerer;
        numbers[4] = _animUnits.LipCornerDepressor;
        numbers[5] = _animUnits.OuterBrowRaiser;
    }

    private void ClassifyAndApply(float[] units){

//      Renderer rend = GetComponent<Renderer>();
//      Face = GameObject.Find ("Face");



        if (units[2] <= 0.264888){
            if (units[3] <= 0.817408){
                if (units[1] <= 0.181886){
                    if (units[0] <= -0.216908){
                        if (units[4] <= 0.395523){
                            if (units[1] <= 0.104226){ 
                                Face. GetComponent<Renderer>().material.mainTexture = textures[3];
                            }
                            else{ 
                                Face. GetComponent<Renderer>().material.mainTexture = textures[0];
                            }

这棵树还在继续，但我认为我的问题是这个，但我不确定.

This tree continues but I think my problem is this but I am not sure.

Face. GetComponent<Renderer>().material.mainTexture = textures[0];

推荐答案

尝试在没有庞大的if结构的情况下执行Face.GetComponent<Renderer>().material.mainTexture = textures[0];，以确保100％无法正常运行.确定要在检查器中拖放所有纹理吗?

Try executing Face.GetComponent<Renderer>().material.mainTexture = textures[0]; without the huge if structure, to be 100% sure it is not working. Are you sure you have all the textures drag-n-dropped in the inspector ?

如果是这种情况，请尝试创建新材质(右键单击项目中的鼠标"选项卡->创建"->材质")，并为其指定Standard着色器.然后将材质提供给您的Face对象.

If that is the case then try creating new material (right-mouse-in-project-tab -> Create -> Material) and give it the Standard shader. Then give the material to your Face object.

设置mainTexture仅在您的对象使用带有名为"MainTexture"的参数的着色器的材质时有效(某些简单的颜色或奇异的fx着色器可能不用于纹理，并且没有这样的参数)

Setting mainTexture only works if your object is using material with shader that has a parameter named "MainTexture" (some simple color or exotic fx shaders might not have use for texture and and have no such parameter)
