MetalCity

MetalCity is night city scape full procedurally generated, for Swift Playgrounds. Its fully written in Swift (5.5) and uses Metal for the rendering engine.

It features:

  • Procedurally generated road and building plots
  • 4 different styles of buildings (simple, tower, blocky and modern)
  • Procedurally generated textures
  • Traffic
  • Static and Autocam modes
  • Fireworks

Its heavily based off Shamus Young’s PixelCity – http://www.shamusyoung.com/twentysidedtale/?p=2940

The fireworks are based on Karl Pickett’s Fireworks Graphics Demo (https://github.com/kjpgit/fireworks) – updated for Swift 4.2 and changes in Metal.

This was written as a way for me to get more familiar with Metal and as its my second Metal app, I’m sure that there are many things I’m doing wrong (feedback and comments welcomed!).

Controls

Tap on screen to toggle the control menu
From here you can:

  • Toggle the autocam on/off
  • Change to the next autocam mode (if autocam is running)
  • Regenerate the city
  • Regenerate the textures (usually also requires regenerating the city afterwards)

If Autocam is running, the camera switches between different camera angles.

If Autocam is off then you can manually move the camera using:

  • 1 finger:

    • drag up and down will rotate camera up and down
    • drag left and right will rotate camera left and right

  • 2 fingers:

    • Drag up and down will move camera forward and backward
    • Drag left and right will rotate camera left and right

  • 3 fingers:

    • Drag up and down will move camera up and down
    • Drag left and right will strafe camera left and right
