Camera

All camera types basically do a bit of logic and then come up with a position and a rotation. Then they pass them over to the Render system to and use them to set the View and pass them to the Audio system to set the listener.

Programming in C++

First Person Camera

#include <extensions/camera/firstperson.h>
API documentation page.

Here's how to do a first person camera.


	// here will be our camera

	Ext::Camera::FirstPersonCamera* camera = nullptr;

	

	// this will be our player

	Entity* player = Entity::Find("player");

	

	// let's make a new camera

	camera = new Ext::Camera::FirstPersonCamera;

	

	// this attaches the camera to the player

	camera->SetFollowing(player);

	

	// this will allow rotation of the camera

	// by moving the mouse cursor

	camera->SetMouselook(true);

	

	// this will rotate the player with the

	// camera. useful if player has a visible

	// 3D model

	camera->SetRotateFollowing(true);

	

	// this will position the camera half a meter

	// above the player entity's middle point

	camera->SetFollowingOffset({0.0f, 0.5f, 0.0f});

	

	// this turns on the camera

	camera->SetActive();

There are other camera types, but they are sort of unfinished.
