The Seed Engine

The Seed Engine is unfinished, we are working on this during the assigment of Game Engine Development for the CITM degree in Video Game Design and Development.

The Seed Engine is a game engine developed in C++ using the external libraries:

  - SDL2

  - OpenGL

  - ImGui

  - GLEW

  - DevIL

  - MathGeoLib

  - GLMath

Guide to execute

  • Download the Engine
  • Unpack .zip
  • Execute .exe

Camera Controls

  • Default Mode:

    • Mouse wheel scroll = Zoom in and out.
    • Mouse wheel click = move around.
    • 'F' = focus camera to selected object.

  • Fly Mode (mouse right click pressed):

    • Mouse movement = look around
    • 'W' = move forward
    • 'S' = move back
    • 'A' = move left
    • 'D' = move right
    • 'Q' = move up
    • 'E' = move down
    • 'LShift' = increase movement speed

  • Focused Mode ('Alt' + mouse left click pressed):

    • Mouse movement = orbit selected object

Windows

  • Windows can be docked around the screen, or keep them floating.

* Main Menu

In this part you can find multiple dropdowns:

  • File: you find a button to open a popUp about de engine, a button with the link to GitHub, and a button to close the engine.
  • Basic Shapes: a list of basic game object shaps to creat.
  • Windows: you can open/close the other windows, and change the therme of the window to "light", "dark", "soft dark" and you can "personalise"
  • Render: a button to render the meshes in wireframe

* Inspector

It shows the components of the selected object, where you can change the name or disable it.

  • Transform
  • Mesh
  • Texture

* Hierarchy

  • Show the list of the objects in the scene and their parents/children.
  • Right click on any object to show menu.
  • 'Delete' / 'Supr' to delete selected game object.

* Console

Don't be afraid to resize the console, the buttons risize with it.

  • Print 3 typs of LOG (Warning, System, Missage), you can filter the different typs of LOG's with they own button (you can see how many are they next to de button).
  • Collapse button: stacks identic logs.
  • Clear button: clear all stored LOGS of the console.
  • If you whant, can show the document and line of that debug.

* Configuration

Headers with options over basic engine functionalities.

  • FPS: Show and limitate FPS, information about frame calculation time.
  • Window: Toggle Fullscreen, resize (or not) the windows, borderless mode, Window information.
  • Visual: Let you activate some additional widgets of the windows: VSync, brightness, lights, dephts test, face culling, color material, textures.
  • Hardware: Shows information about the hardware your PC is using.

* Scene

  • Draw the render of the scene in this windows

How the game engine works

  • Game Objects:

    • Everything in the scene is stored in game objects, they have variable components to add to them, in order to be fully personalisable.
    • Game objects can be selected from the hierarchy window, this also makes the inspector appear.
    • Game objects have parents and childs, which makes them interactuate in different ways.
    • In the inspector, all of the selected game object components can be modified.
    • Disabling game objects in inspector prevents rendering itself plus all of its childs.

  • Components:

    • Transform: stores the information of the local position, rotation and scale. Global position is calculed by their parent transform.
    • Mesh: stores the mesh that is rendering every frame.
    • Texture: stores the texture rendering on the mesh, can be changed to print no texture, or to print default checkers texture.

  • Drag and drop:

    • Any FBX can be dropped on the scene. A game object will be created with child objects that store their meshes, if the FBX has a texture, and is loaded in Assets folder, it will be loaded automatically.
    • Any PNG and DDS image can be dropped on the scene. This will be loaded as the selected game object texture (creating a Texture Component if there isn't one yet).
