# Sequential Update System

Sequential update system is responsible for updating active entities sequentially.

# updateSequential Callback

System loops through all active entities sequentially based on their updateSequential callback order. For each entity updateSequential callback is executed.

# Remarks

Due to the sequential nature of sequential update system, it is recommended to reduce workload in updateSequential callback to increase performance. For example, move as much logic to updateParallel as possible, and only use updateSequential callback if there are needs to write to shared blocks.
