Corona Geek #160 – Homing Turret Vector Math Breakdown – Using Gravity In Games – Part 6
On today’s Corona Geek Hangout we continued our game development discussion by looking at an isolated homing turret code example. Ed Maurina walked us through how to create a continuous moving target, which our turret then tracked across the screen. We also saw how to turn regular “dumb” missiles into homing missile that followed the target after the projectiles were launched from the turret.
Watch the previous Hangout for more details on how the game works.
- part 1 – game mechanics and how gravity works
- part 2 – player jumping and keyboard inputs
- part 3 – creating level using platforms, spikes, coins, and monsters
- part 4 – building game objects and restarting levels
- part 5 – adding turrets
The game’s source code is available. If you haven’t already, download the updated project.
Also, join us next week when we talk with Dean Murphy, developer of Crystal, the #1 ad blocker for iOS 9. Dean will share his journey from developing with Corona SDK for cross platform development to focusing exclusively on iOS development.
