我正在尝试将 uint 传递给我的着色器，但我一定做错了什么，因为在着色器中该值是 3212836864 而不是 4294967295。

我有一个顶点数组，在将每个顶点发送到着色器之前将其存储在其中glBufferSubData(GL_ARRAY_BUFFER, 0, sizeof(Vertex) * 4 * vertexBufferArrayInserts, vertexBufferArray);

这些是我的glVertexAttribPointer电话：

    shaderPosAttrib = glGetAttribLocation(shaderProgram, "position");
    glVertexAttribPointer(shaderPosAttrib, 2, GL_FLOAT, GL_FALSE, sizeof(Vertex), (void*)offsetof(Vertex, position));
    glEnableVertexAttribArray(shaderPosAttrib);

    shaderTexCoordAttrib = glGetAttribLocation(shaderProgram, "texCoord");
    glVertexAttribPointer(shaderTexCoordAttrib, 2, GL_FLOAT, GL_FALSE, sizeof(Vertex), (void*)offsetof(Vertex, texCoords));
    glEnableVertexAttribArray(shaderTexCoordAttrib);

    shaderColorAttrib = glGetAttribLocation(shaderProgram, "color");
    glVertexAttribPointer(shaderColorAttrib, 1, GL_UNSIGNED_INT, GL_FALSE, sizeof(Vertex), (void*)offsetof(Vertex, color));
    glEnableVertexAttribArray(shaderColorAttrib);

这是顶点结构

struct Vertex
{
    Vector2<GLfloat> position;
    Vector2<GLfloat> texCoords;
    GLuint color;

    Vertex() {

    }

    Vertex(Vector2<GLfloat> position, Vector2<GLfloat> texCoords, GLuint color) {
        this->position = position;
        this->texCoords = texCoords; …
