Blue Tengu’s Live Game Development Show – Season 2, Episode 11

Blue Tengu - Tricky Decisions
In this episode, we return to the enemy AI to revise how we do our clustering behavior, coming up with a much simpler and less processor intensive way of grouping the enemies that fly at the player.

To avoid the processor-heavy calculation of each enemy x each enemy (n^n complexity), we instead relegate control to a central AI controller, lowering the complexity (x*n complexity) and making the grouped enemies more manageable. All of the spawning was moved to the central controller, and it controls the child enemy movements.

Tasks Worked on This Episode:

  • Create a Central AI Controller
  • The AI Controller Spawns Children Enemies
  • The AI Controller Dictates Child Enemy Movements


We also revised our Twitch tip jar so that any donations get announced during the stream.
