# Projectile

## 导入类

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.
```zenscript
import crafttweaker.api.entity.type.projectile.Projectile;
```


## Extending Entity

Projectile extends [Entity](/vanilla/api/entity/Entity). That means all methods available in [Entity](/vanilla/api/entity/Entity) are also available in Projectile

## 使用方式

:::group{name=getEffectSource}

Return Type: [Entity](/vanilla/api/entity/Entity)

```zenscript
// Projectile.getEffectSource() as Entity

myProjectile.getEffectSource();
```

:::

:::group{name=getOwner}

Return Type: [Entity](/vanilla/api/entity/Entity)?

```zenscript
// Projectile.getOwner() as Entity?

myProjectile.getOwner();
```

:::

:::group{name=setOwner}

```zenscript
Projectile.setOwner(entity as Entity?)
```
