Game Engine Screenshot

ScreenShot

Systems

Hierarchy

The hierarchy contains all game objects in the scene with its corresponding parents and children. The scene is already named and a main camera is automatically created, when game objects are created or dragged, it will be placed as a child of the existing scene as it will show on the game engine scene. All game objects can be editted, if a game object with childs is editted, its childs will perfom the same way.

Hierarchy

Inspector

In the inspector at the right of the screen there will be information about the game object selected in the hierarchy. All game objects will contain its name and a component transform to be able to move its position, rotation and scale. If a game object is has a mesh, it will show a component mesh with information about the file which it corresponds to (his path). If the game object contains a material, it will show a component material with infomation about it (its path and size) and some options to edit it.

Inspector

If the game object corresponds to a camera, the component camera will appear and the main view of the camera can be editted.

Camera

Optimization

Quadtree: With Static Game Object check box. Camera Culling: hide Game Objects that are not in Main Camera.

Mouse Pickying

With the mouse we can select and put the focus to Game Object on the scene as well as in the hierarchy.

Engine State

On the top of the screen there is an engine state controller with its commands “Start/Pause/Stop” that will show the scene from the main camera perspective when played.

State

Bounding Box

We use AABB to encapsulate meshes and discarded using frustum culling in editor mode and mouse picking enabled to select game object on scene.

Shaders Pipeline

Shaders Pipeline is implemented in the code, when a game object is selected, open the material component in the inspector and click the checkbox of the default shader to apply it. This is still not working exactly how it is suposed to be.

Configuration

There is a configuration window where the user will be able to see the application information including the fps is running at, main information about the input and harware and will be able to edit the window characteristics of the application.

Configuration

Console

A console window will be appear in the bottom of the screen indicating the user what the app is doing and showing error information if needed.

Console

Controls

WASD: Camera Movement
Right Click: Rotate Camera
Shift: Duplicate Speed Movement
Mouse Wheel: Zoom in and out
F: Focus Camera to Gameobject
Alt+Left Click: Rotate around Gameobject
Drag&Drop: Drag any model or texture to apply to scene
