Create Shader Class

[Zomon333]

We need a class to handle ingame shaders. This will add a helpful level of abstraction.

• [x] Default constructor initializes blank shader
• [x] Shader constructor takes (GLenum shaderType, string code)
  • [x] Shader should store code given for future reference
  • [x] Shader should allocate ShaderID on construction
• [x] Shader should have make() function for compilation
  • [x] Create ShaderObject: glCreateShader(GLenum Type)
  • [x] Give Shader source: glShaderSource(GLuint shader, GLsizei count, GLchar* strong, const GLint length)
  • [x] Compile Shader: glCompileShader(GLuint shaderID)
  • [x] Verify Success: glGetShaderiv(GL_COMPLE_STATUS)
  • [ ] Get logs on failure: glGetShaderInfoLog()
• [x] getID() function to get Shader ID
• [x] isShader() function using glIsShader()
• [x] Deconstructor should call glDeleteShader(GLuint shader) if glIsShader()==GL_TRUE

If we can think of other requirements, we'll comment them down below.

• [x] Shader will store GLenum for ShaderType
• [x] GLenum getType() to get shader's type.

[Zomon333]

Shader must have function:

• [x] string loadShader(char* file)
  • [x] Must open file and return contents as string
  • [x] May be static such that we can call Shader::loadShader(); May not be static and set this->code=loadShader();

[Zomon333]

Shader must have a new constructor:

• [x] Shader(GLenum type); //does not initialize code, for use with loadShader();
