# ApplySkillShortcut Anti-spam

## What it is
`CECHostPlayer.ApplySkillShortcut(...)` has a small client-side anti-spam gate to prevent input floods (touch/mouse spam, key repeat, UI double-fire) from generating excessive trace/cast work.

This is **not** a replacement for server cooldowns or validation. It’s client-side hygiene to keep the client stable and reduce redundant requests.

## How it works
The gate is implemented inside `Assets/Scripts/CECHostPlayer.Skill.cs`:

- **Global minimum interval (ANY)**: blocks ultra-high-frequency bursts across *all* skills.
- **Per-skill minimum interval (PER_SKILL)**: blocks rapidly pressing the *same* skill repeatedly.
- **Charge exception**: if the player is charging a skill and presses the **same** skill again to release immediately, that press is **allowed** (so charging remains responsive).

The timing source is `Time.unscaledTime` so the throttle stays consistent even if `Time.timeScale` changes.

## Tunables
In `CECHostPlayer.Skill.cs`:

- `APPLY_SKILL_SHORTCUT_MIN_INTERVAL_ANY` (default `0.05s`)
- `APPLY_SKILL_SHORTCUT_MIN_INTERVAL_PER_SKILL` (default `0.12s`)

If you need to tweak feel:

- Lower **ANY** carefully; it protects against accidental double-fire from UI/input systems.
- Lower **PER_SKILL** if skills feel “eaten” during fast tapping, but keep it high enough to block spam.

## Why the charge exception exists
Chargeable skills commonly use a second press to “cast now”. Blocking that second press makes charging feel broken, so the anti-spam explicitly does not block it.
