Dynamic Objects

Eggman (Scrap Brain 2) is an object in Sonic the Hedgehog, appearing in the post-level cutscene in Scrap Brain Zone Act 2. He stands behind the light barrier which protects him from Sonic. Once Sonic approaches, he jumps onto a button which triggers the crumbling floor to fall apart beneath him, sending him to Scrap Brain Zone Act 3.

Code

File: _incObj/-- Eggman - Scrap Brain 2.asm

Changes from Sonic 1
  • Word-length obPriority pointer due to the new Priority Manager.
  • Word-length obRespawnAddr added due to the S3K Object Manager.
  • Removed from the Static Object Pointer List due to its dynamic nature.

Subtypes

This object has no subtypes, but obSubtype (along with the following OST byte) are used as a flag for triggering Eggman to jump onto the button (S1Fixed will change this to use scrap RAM). The ASCII value "SW" triggers the floor to crumble.
