  • Concept
  • block_scope (variable)

Concept

• All executation start at o_block_start.
• When started, o_block_start run script block_execute_start

• On each block:

  • user_event(0) run once the block is called.
  • user_event(1) run every step the block is executing.
  • user_event(2) run once when the block finish executing.
  • block_execute_next called for next block.

block_scope (variable)

block_scope is an array contain blocks that has variable_map inside. block_scope is used to find variable value and target actor.

Note

block_scope iterate from last member to first, and break when found. Thus “local” variable will return before global var.
