顶点着色器上的openGL GLSL“void”解析错误

因此，我正在关注3D游戏引擎上的“theBennyBox”的Youtube系列，并且在第9/10页大概出现了一些问题 .

我收到了错误

顶点着色器无法编译时出现以下错误：错误：0：5：错误（＃132）语法错误：“void”解析错误错误：错误（＃273）1编译错误 . 没有代码生成

这是我所有的东西：

我的资源加载器（读取文件）

package com.base.engine;

import java.io.BufferedReader;
import java.io.FileReader;

public class ResourceLoader {
    public static String loadShader(String fileName) {
        StringBuilder shaderSource = new StringBuilder();
        BufferedReader shaderReader = null;

        try {
            shaderReader = new BufferedReader(new FileReader("./res/shaders/" + fileName));
            String line;
            while ((line = shaderReader.readLine()) != null) {
                shaderSource.append(line).append("\n");
            }

            shaderReader.close();
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }

        return shaderSource.toString();
    }
}

我的Shader类：

package com.base.engine;

import static org.lwjgl.opengl.GL20.*;
import static org.lwjgl.opengl.GL32.*;

public class Shader {
    private int program;

    public Shader() {
        program = glCreateProgram();

        if (program == 0) {
            System.err.println("Shader Creation failed: could not find valid memory location in constructor");
            System.exit(1);
        }
    }

    public void bind(){
        glUseProgram(program); 
    }

    public void addVertexShader(String text) {
        addProgram(text, GL_VERTEX_SHADER);
    }

    public void addGeometryShader(String text) {
        addProgram(text, GL_GEOMETRY_SHADER);
    }

    public void addFragmentShader(String text) {
        addProgram(text, GL_FRAGMENT_SHADER);
    }

    public void compileShader() {
        glLinkProgram(program);

        if (glGetProgrami(program, GL_LINK_STATUS) == 0) {
            System.err.println(glGetShaderInfoLog(program, 1024));
            System.exit(1);
        }

        glValidateProgram(program);
        if(glGetProgrami(program, GL_VALIDATE_STATUS) == 0){
            System.err.println(glGetShaderInfoLog(program, 1024));
            System.exit(1);
        }
    }

    private void addProgram(String text, int type) {
        int shader = glCreateShader(type);

        if (shader == 0) {
            System.err.println("Shader Creation failed: could not find valid memory location when adding shader");
            System.exit(1);
        }

        glShaderSource(shader, text);
        glCompileShader(shader);

        if (glGetShaderi(shader, GL_COMPILE_STATUS) == 0) {
            System.err.println(glGetShaderInfoLog(shader, 1024));
            System.exit(1);
        }

        glAttachShader(program, shader);
    }
}

我的Game类，我将着色器初始化为单个多边形：

package com.base.engine;

import org.lwjgl.input.Keyboard;

public class Game {
    private Mesh mesh;
    private Shader shader;

    public Game() {
        mesh = new Mesh();
        shader = new Shader();

        Vertex[] data = new Vertex[] {new Vertex(new Vector3f(-1, -1, 0)),
                                      new Vertex(new Vector3f(0, 1, 0)),
                                      new Vertex(new Vector3f(1, -1, 0))};
        mesh.addVertices(data);
        shader.addVertexShader(ResourceLoader.loadShader("basicVertex.vs"));
        shader.addFragmentShader(ResourceLoader.loadShader("basicFragment.fs"));

    }

    public void input() {
        if (Input.getKeyDown(Keyboard.KEY_UP)) {
            System.out.println("We've just pressed up");
        }
        if (Input.getKeyUp(Keyboard.KEY_UP)) {
            System.out.println("We've just released up");
        }

        if (Input.getMouseDown(1)) {
            System.out.println("We've just pressed right-mouse at "
                    + Input.getMousePosition().toString());
        }
        if (Input.getMouseUp(1)) {
            System.out.println("We've just released right-mouse");
        }
    }

    public void update() {

    }

    public void render() {
        shader.bind();
        mesh.draw();
    }
}

和我的着色器:(错误显示为顶点着色器，但如果我注释掉顶点着色器，则片段看起来像什么都不做 . ）

顶点:(第5行，void main（），显然是麻烦制造者）

#version 330

layout (location = 0) in vec3 position

void main()
{
    gl_Position = vec4(0.25 * position, 1.0);
}

分段：

#version 330

out vec3 fragColour;

void main()
{
    fragColour = vec4(0.0, 1.0, 1.0, 1.0);
}

我很欣赏这一切都很长但如果你知道的话请帮助我！
