Hey guys! I have spent the last day trying to debug this and I am beyong stuck. I am getting an error when trying to use VAO's inside of SFML and not sure if it is SFML or it is my own opengl code
GLenum err = glewInit();
if (err != GLEW_OK)
{
std::cout << "NOT WORKING" << std::endl;
}
g_vertex_buffer_data.push_back({ -1.0f, -1.0f, 0.0f });
g_vertex_buffer_data.push_back({1.0f, -1.0f, 0.0f});
g_vertex_buffer_data.push_back({ 0.0f, 1.0f, 0.0f });
const char* vertexShaderSource =
"#version 330\n\
in vec4 position;\
void main(void) {\
gl_Position = position;\
}";
// compile fragment shader source
const GLchar* fragmentShaderSource =
"#version 330\n\
void main(void) {\
gl_FragColor = vec4(1.0,1.0,1.0,1.0);\
}";
/* Creating Shader */
this->programId = glCreateProgram();
this->vId = glCreateShader(GL_VERTEX_SHADER);
this->fId = glCreateShader(GL_FRAGMENT_SHADER);
/* Get Shader Size */
int vertexShaderLength = strlen(vertexShaderSource);
int fragmentShaderLength = strlen(fragmentShaderSource);
/* Loading and binding shader */
glShaderSource(this->vId, 1, &vertexShaderSource, NULL);
glShaderSource(this->fId, 1, &fragmentShaderSource, NULL);
/* Compile Shaders */
glCompileShader(vId);
glCompileShader(fId);
/* Attach Shaders */
glAttachShader(this->programId, this->vId);
glAttachShader(this->programId, this->fId);
/* Linkg program */
glLinkProgram(this->programId);
/* Use and bind attribute */
glUseProgram(this->programId);
this->positionId = glGetAttribLocation(this->programId, "position");
glUseProgram(0);
/* VAO Time */
glGenVertexArrays(1, &this->vaoId);
glBindVertexArray(this->vaoId);
/* VBO Time assigning to VAO */
glGenBuffers(1, &this->vboId);
glBindBuffer(GL_ARRAY_BUFFER, this->vboId);
glBufferData(GL_ARRAY_BUFFER, sizeof(g_vertex_buffer_data) * sizeof(sf::Vector3f), &g_vertex_buffer_data[0], GL_STATIC_DRAW);
glEnableVertexAttribArray(this->positionId);
glVertexAttribPointer(this->positionId, 2, GL_FLOAT, GL_FALSE, sizeof(sf::Vector3f), 0);
/* Close out bindings */
glBindVertexArray(0)
glBindBuffer(GL_ARRAY_BUFFER, 0);
Then the draw function:
glUseProgram(this->programId);
glBindVertexArray(this->vaoId);
glDrawArrays(GL_TRIANGLES, 0, 3);
glBindVertexArray(0);
glUseProgram(0);
gameWindow.glPushStates();
The error code I get is:
opengl error in user code (1282)?
Any help would be greatly apprciated
