# Run an Effect

> Run a named effect manually with yourself as the caster.

Runs a [named effect](named-effects) manually, with **you as the caster**. It's the manual-testing counterpart of a mob's `run`: write an effect, fire it on yourself, see it instantly without setting up a mob.

## Usage

```text theme={null}
/nme effect start <effect>
```

**Alias:** `/nme e start <effect>` **Permission:** `nmentities.effect` **Player-only:** yes

## Arguments

| Argument | Required | Description                                                                                                                                      |
| :------- | :------- | :----------------------------------------------------------------------------------------------------------------------------------------------- |
| `effect` | ✅        | A loaded effect id from the `Effects/` folder. Autocompletes to every loaded global effect. Mob-local effects need their mob and are not listed. |

## How the effect resolves

The effect runs as if you were the mob:

* `@self` (the default targeter) is **you**.
* Radius targeters (`@playersRadius[N]`, ...) resolve around **your location**.
* `@target` resolves to **nothing**, since there's no trigger entity, so those lines do nothing.
* `<caster.name>` is your name, and caster-scope [variables](variables) live on you.

## Examples

```text theme={null}
/nme effect start greeting
/nme e start shockwave
```

## Notes

* **The effect really runs on you.** `damage @self`, `suicide`, or a `forever` repeat all apply to your player. Test destructive effects with care.
