Construct Method

Initialize the GameEngine with screen and window settings. Configuration with numerical values for the screen size and pixel width, and boolean values for fullscreen, vsync, and dirty pixel.

Parameters:

  • screenWidth: Width of the screen.
  • screenHeight: Height of the screen.
  • pixelWidth: Pixel width on the screen.
  • pixelHeight: Pixel height on the screen.
  • fullScreen: Full-screen mode.
  • vsync: Vertical synchronization.
  • dirtyPixel: Dirty pixel rendering.

Example:

GameEngine::Construct(800, 600, 1, 1, false, false, false);

This code initializes the GameEngine with a screen size of 800x600 and x and y pixel width by 1. The rest of the parameters are disabled.

DrawString Function

Parameters:

  • x: X-position to start.
  • y: Y-position to start.
  • s: String to be drawn.
