Computer Engineering (Programming Language: Swift)
- 1. Computer Engineering By Sethmi Kachchakaduge, Kevin Adams, Kimi Hirano
- 2. Overview ● Intro ● Project Description o Building the platform o Example Code o Flappy Fly Code ● Analysis o Challenges o What we learned
- 3. Intro to Computer Engineering ● Combines fields of electrical engineering and computer science to develop computer hardware and software ● More focus on digital systems ● Programming
- 4. Project Description ● Created “Flappy Fly” o Version of Flappy Bird o Swift ● Programmed code o Xcode ● SpriteBuilder o Built in parts o Location control
- 5. Building the platform ● Spritebuilder o Background o Ground o Obstacles o Hero o Nodes o Physics
- 7. Coding Basics ● Basic Comparators (==, >, <, >=, <=) ● Basic Operators (=, +=, -=, *=, /=, %=) ● Variables ● Logic o if and else o True and False
- 8. Example • Var flappyFly = 6 • flappyFly > 7 ‘false’ • flappyFly < 7 ‘true’ • If (flappyFly>4){ • ‘flappyFly+=1’ • } • Else { • “flappyFly does nothing” • }
- 9. Control Flow ● For loops ● For in loops ● While loops ● Do while loops
- 10. Flappy Fly Code ● Variable Ex o var_gameOver = false ● Function Ex ○ func spawnNewObstacle() { var prevObstaclePos = _firstObstaclePosition if _obstacles.count > 0 { prevObstaclePos = _obstacles.last!.position.x } ● For loop Ex o for ground in _grounds { // get the world position of the ground let groundWorldPosition = _physicsNode.convertToWorldSpace(ground.position // get the screen position of the ground let groundScreenPosition = self.convertToNodeSpace(groundWorldPosition) // if the left corner is one complete width off the screen, move it to the right
- 12. Final Game
- 13. Challenges ● Inserting code in proper location ● Understanding the code ● Correctly following building process
- 14. What we learned? ● Different syntax ● Order matters ● Patience ● Simplified code
