Overview
Daniel redesigned visual assets and mechanics for a Space Invaders tutorial project in Xcode, replacing placeholder blocks with downloaded pixel art for the ship, projectile, and background.
Baseline controls, directional movement, and single-bullet limits were tested and adjusted, including fine-tuning the projectile spawn location and speed.
Daniel worked through Interface Builder layering and button relinking issues while acknowledging tutorial creator Matt Healy Apps and having started with Xcode roughly a week prior.
Themes
Visual asset replacement and pixel art selection in Xcode.
Tuning projectile spawn coordinates and movement speed variables.
Interface Builder layering and storyboard button configuration.
Tutorial attribution and background experience in Xcode.
Developments
Daniel reviewed the baseline Space Invaders code and tested ship movement and shooting controls in a game build.
Daniel imported a spaceship PNG to replace the original red block asset.
Daniel tested a laser image before selecting a fireball PNG for the projectile.
Daniel adjusted the projectile y-coordinate from 650 to 590 before settling on 620 to align with the ship front.
Daniel updated the projectile movement variable from 7 to 25 and settled on 18.
Daniel inserted a space background image and relinked storyboard UI buttons after deleting and re-pasting interface elements.
Uncertainties & gaps
The legality of saving and using images found directly via search engines remained uncertain.
The standard procedure in Xcode to send a background image behind other storyboard elements was uncertain.
