Detailed Description

A class used to load and use shaders.

This class is used to load and use shaders in the game engine. The shader takes two files, one for the vertex shader and one for the fragment shader, and compiles them into a GPU program to be used by the game engine to render models. If no shader scripts are provided, it will use the default shader. A fragment shader will be required first.

Example

Engine::Graphics::Shader shader;
 
class TestObject : public Engine::Node {
  void Draw() override {
    Engine::Game::getInstance().GetRenderer().UseShader(shader);
    Engine::Game::getInstance().GetRenderer().DrawMesh(&mesh);
  }
};

Constructor & Destructor Documentation

Shader() [1/3]

Engine::Graphics::Shader::Shader

(

)

Default constructor.

uses the default shader files

Shader() [2/3]

Engine::Graphics::Shader::Shader

(

const char *

frag

)

Constructor with default vertex shader.

Shader program that uses the default vertex shader. Takes in a shader file for the fragment shader

Parameters

frag	the path to the fragment shader

Shader() [3/3]

Engine::Graphics::Shader::Shader	(	const char *	frag,
		const char *	vert
	)

Main constructor for a shader.

Take in a fragment and vertex shader file to construct a shader.

Parameters

frag	the path to the fragment shader
vert	the path to the vertex shader

Member Function Documentation

GetShaderProgram()

unsigned int Engine::Graphics::Shader::GetShaderProgram

(

)

Gets the shader program.

Returns the shader program that was loaded into the GPU. If the shader is not compiled, it will compile the shaderand and then return the shader program.

Returns

the shader program
