Only has an effect on area triggers with the 'water' proxy type; setting it on any other proxy type has no effect.

Currently only 'lava' has special behavior: it occasionally destroys submerged shapes. Lava behavior requires

shapes to be included in the content list via [AreaTrigger](../Game-Script-Environment/Userdata/AreaTrigger.md): setIncludeShapesInContent.

**Parameters:**

| Name | Type | Description |
| --- | --- | --- |
| `areaTrigger` | [AreaTrigger](../Game-Script-Environment/Userdata/AreaTrigger.md) | The area trigger instance. |
| `waterType` | integer | The liquid type. (See [sm.areaTrigger.liquidType](../Game-Script-Environment/Static-Functions/sm.areaTrigger.md#liquidtype)) |
