I have a class to load textures. It works fine for the first try, but the second time I try to create a texture, it gives me an access violation exception at glTexImage2d().
Code:
Texture::Texture(const char* textureFile)
{
glGenTextures(1, &textureID);
glBindTexture(GL_TEXTURE_2D, textureID);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
int width, height, nrChannels;
unsigned char* data = stbi_load(textureFile, &width, &height, &nrChannels, 0);
if (data)
{
//exception occurs here
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, data);
glGenerateMipmap(GL_TEXTURE_2D);
}
else
{
printf("Could not load image %s!\n", textureFile);
}
stbi_image_free(data);
}
