# ActionSequence
## Overview
ActionSequence is **OVERDARE’s core direction system** that allows you to compose animation, effects, cameras, and more into a single action in an integrated timeline. Frequently used in-game effects and script execution timing can be **visually structured** within a timeline-based editing environment.
Within a single sequence, you can control the following elements together:
* Play hit effects in sync with attack animations
* Play sounds at specific timings
* Apply camera shake at the moment of impact
* Apply damage to targets within the attack range
* Trigger script events at specific frames
* Set movement restrictions or parry windows during attacks
ActionSequence provides an editing environment where these effects and script execution timings can be **precisely controlled over time**. This allows you to, for example, play an effect after a delay following an attack, or add camera direction afterward—**all without relying on scripts, but instead directly reviewing and editing them on the timeline**.
This approach enables you to build **action direction** intuitively and instantly verify the results, providing an **efficient production workflow**.
## Key Features
### Timeline-based visual editing
ActionSequence provides a **timeline-based editing environment** where animations, effects, sounds, and camera directions can be visually arranged and adjusted in chronological order.
This allows you to **edit direction timing intuitively without using scripts**.
### Support for various direction elements
ActionSequence supports not only animations, sounds, camera direction, and effects, but also **collision shapes for attack detection**, allowing both **direction and gameplay logic** to be composed within a single timeline.
### Integration with gameplay logic
ActionSequence provides **event tracks** and **trigger tracks**, enabling script logic to be executed at specific points on the timeline. This allows direction and gameplay logic to be naturally connected.
### Optimized for multiplayer environments
ActionSequence is designed to **operate reliably in networked environments**.
**Sequence execution begins on the server**, while the **actual direction is played on each client**. The server synchronizes the overall progression based on the sequence execution timing, and any **time differences between clients are automatically corrected**.
Additionally, to ensure gameplay consistency, **core logic such as attack collision detection is processed on the server**.
