Blox Game Engine:Tutorials:Basics

Introduction

This tutorial will explain the basics of the Blox Game Engine such as Sprites, Textures, Fonts, Sounds, Colors and Scenes. I am assuming that you have the latest version of the Blox Game Engine.

Scenes

Everything that you want rendered to the screen must be in a graphics scene. This allows for batching the entire scene at once to the video card, for much much faster rendering speed. There are currently 6 methods in the video driver class that are associated with scenes. They are:

ClearScene(BGECOLOR color);
BeginScene();
EndScene();
PresentScene();
StartScene();
StopScene();

I will explain each one.

ClearScene(BGECOLOR color);

This clears the backbuffer to a specific color, clearing any data(images, drawings, fonts) that is currently on it. This is should be called every frame.

BeginScene();

This begins a scene. All of your rendering should be inbetween the BeginScene() and the EndScene() methods.

EndScene();

This stops a scene. All of your rendering should be in-between the BeginScene() and the EndScene() methods. After this method is called, you most likely will want to call PresentScene().
