使用着色器在raylib中时，对象未按鼠标位置移动。

这个问题很可能是由于着色器在渲染时干扰了raylib鼠标位置的处理。可以尝试通过以下步骤来解决：

1.使用raylib提供的GetMousePosition()来获取鼠标位置。

2.在着色器和渲染函数之间调用UpdateDrawModelMatrix()。

以下是代码示例：

#include "raylib.h"

#define SCREEN_WIDTH 800
#define SCREEN_HEIGHT 450

int main(void)
{
    // Initialization
    //--------------------------------------------------------------------------------------
    InitWindow(SCREEN_WIDTH, SCREEN_HEIGHT, "raylib [core] example - 3d camera mode");
    SetTargetFPS(60);
    
    // Load shader
    Shader shader = LoadShader(0, "resources/shaders/glsl330/base_lighting.vs");
    
    // Load model
    Model model = LoadModel("resources/models/crate.obj");
    
    // Set model position and scale
    model.position = (Vector3){ 0.0f, 0.0f, 0.0f };
    model.scale = (Vector3){ 1.0f, 1.0f, 1.0f };
    
    // Define camera and camera target
    Camera3D camera = { 0 };
    camera.position = (Vector3){ 0.0f, 10.0f, 10.0f };
    camera.target = (Vector3){ 0.0f, 0.0f, 0.0f };
    camera.up = (Vector3){ 0.0f, 1.0f, 0.0f };
    camera.fovy = 45.0f;
    camera.projection = CAMERA_PERSPECTIVE;
    
    // Main game loop
    while (!WindowShouldClose())    
    {
        // Update
        //----------------------------------------------------------------------------------
        UpdateCamera(&camera);
        
        // Get mouse position
        Vector2 mousePos = GetMousePosition();
        
        // Set model position according to mouse position
        model.position = (Vector3){ mousePos.x - SCREEN_WIDTH / 2, -(mousePos.y - SCREEN_HEIGHT / 2), 0.0f };
        
        // Update shader and draw model
        BeginDrawing();
            
            ClearBackground(RAYWHITE);
            
            // Update and draw shader
            UpdateDrawModelMatrix(shader.locs[LOC_MATRIX_MODEL], model.transform);
            BeginShaderMode(shader);
            
                DrawModel(model, (Vector3){ 0.0f, 0.0f, 0.0f }, 1.0f
