Pinky_Engine_v.1.0

High-level System: User Interface

• System to render a variety of widgets on screen
• UI Game Objects/Widgets:
  • Canvas:
    • surface that represents the game window. What is inside of it will be rendered to game
    • automatically created when any UI Game Object is created and there is no canvas on scene
  • Image: displays an image. Options to change its colour and the texture attached to it
  • Text: renders the desired text ("Hello World" by default). Option to change the font colour and size
  • Button: it is formed by two Games Objects:
    • Text: if the user desires to input a text
    • Button: holds the logic of the button with the following states: Normal, Focusd, Pressed, Selected and Release
      • Option to change the colours of each state
      • Option to change the colour of the texture
      • Option to change the texture
      • It can call custom functions (like the fade in the demo)
  • Input Box: allows player to input any text when selected :
    • Input box Game Object holds the logic and has the same states as button
    • Text Game Object to store the input text (and be able to move it around)
    • It has the option to put a character limit
  • Checkbox: composed of multiple Game Objects:
    • Checkbox as the parent of the rest holds the logic to disable the checkmark and execute a desired function
    • Text if user wants to put a label to the widget
    • Background behind the checkmark
    • Checkmark, changes when the Checkbox parent is changed
    • As with button, option to change the colours of the states and of the textures
• All of the UI Game Objects can be navigated through with tab (change the selected one)
• Logic of all the UI works only in play mode
• Buttons allow input from the keyboard (spacebar)
• There is a demo that shows the functionality of all the Widgets:
  • Main menu with a fullscreen background, with an imput box and a button to start, when pressed fades away
    to the next scene
  • Next scene has the town of the second assignment and a crosshair in the middle of the screen
  • Pressing F1 in this scene opens up a menu, with a checkbox to drag the window and to toggle Vsync

Pinky_Engine_v.0.2

Features

• Load and draw FBX files by dragging them to the engine from anywhere in the Hard Drive
• Load and apply DDS/PNG textures by dragging them to the engine from anywhere in the Hard Drive
• Game Object structure, one for each loaded mesh. Inspector shows the following:
  • Each GameObject can have 4 components: Transform, Mesh, Material and Camera
    • Transform component that allows to translate, rotate and scale Game Objects, both with the inspector and guizmos
    • Mesh component:
      • Allows to show vertex normals, face normals of the geometry, OBB, and global AABB
    • Material component allows to change the color (with a color picker) and a toggle to show the checkers
    • Camera component:
      • User can modify the near plane, far plane and FOV
      • Game camera checkbox to enable or disable if the component is the rendering game camera
      • Meshes can be discarded using Frustum Culling, checkbox to enable or disable
  • User can add mesh (choose a primitive shape), material and camera (can't add more than one of each for each Game Object, like in Unity Engine)
  • Mesh and material component can be deleted pressing the cross icon
  • Toggle to enable and disable Game Object, it will not render and will appear slightly turned off in the hierarchy
  • Clicking the name allows the user to change it (press enter to save it and esc to cancel)
  • GameObjects can be picked from the world using the mouse
• Resources and CFF
  • Models, meshes and textures are saved with our own format under Library folder
  • Scene can be serialized to a file that can be loaded
  • Upon start, all resources not managed inside Assets are generated in Library
  • Library folder regenerates from Assets + meta content
  • All resources use reference counting
• Hierarchy:
  • User can fold and unfold the children of a parent
  • Multiple selection of Game Objects
  • Delete Game objects from the engine deletes them from the hierarchy
  • Move Game Object to change its parent
  • Right click Game Object allows to create a child with a primitive shape or empty
• Console Window:
  • Show the geometry and texture loading process
  • Show the libraries initialization process
  • Special messages for errors and warnings (highlighted in red and yellow)
  • Button to clear the console.
  • Search option to look for messages
• Play time:
  • User can user can Start / Pause / Stop / Step the simulation and recover its original state
  • 2 timers show the real time since the engine started and the game time since the simulation started (play button)
• Cameras:
  • There are 2 windows: one with editor view and another withe the game view
  • Game view is captured with a Game Object and can be changed
  • Each one has its own framebuffer and the user can visualize both at the same time
