# roblox animation and vfx

## When to Load

Load when implementing character animation, particle or beam effects, tweens, camera feedback, or visual cleanup.

## Quick Reference

- Load tracks through an `Animator` on a `Humanoid` or `AnimationController`; set `AnimationTrack.Priority` deliberately.

- Use `GetMarkerReachedSignal()` for named gameplay or presentation cues, then disconnect or replace the listener when the track ends.

- A burst `ParticleEmitter` usually has `Rate = 0` and uses `:Emit(count)` with a bounded lifetime; use pooling for frequent effects.

- Beams and trails need two attachments with a stable world-space relationship and a cleanup owner.

- Tween a bounded set of properties with `TweenService:Create`; cancel or destroy temporary effects when their owner ends, and use `Debris:AddItem` for simple lifetimes.

- In Server Authority projects, keep synchronized animation logic in `RunService:BindToSimulation()` (requires `Workspace.UseFixedSimulation` enabled in Studio), query current tracks instead of caching handles across rollback, and make predicted effects reversible.

- - Use effect-density triage to choose specimens, then profile particles, lights, post-processing, and camera work on target devices.

+ - Profile particle counts, lights, post-processing, and per-frame camera work on the target device class.
