Member Function Documentation

void yage::Camera::move ( const glm::vec2 & direction )

Moves the camera using a two-dimensional displacement vector to describe the movement.

Parameters

direction Two-dimensional vector to describe the displacement of the camera.

void yage::Camera::update ( Shader & program )

Updates the camera matrix value in the shader program that is passed to it.

This must be a parameter P in the shader for this function to work.

Parameters

program Shader program to make changes to.

Todo:: Make this function more general to be able to be able to use any parametre in then shader as the camera matrix and not make it dependent on it being P.

void yage::Camera::zoom ( float factor )

Zooms the camera by an incremental amount.

Parameters

factor Factor by which the camera should zoom. This can also be a negative number for the camera to zoom out.
