# void EnvWriteString(Building, str, str)

[Family: Global](/en/CKS/familias/global/)

## Exact signature

```text
void EnvWriteString(Building, str, str)
```

## Description

Requests a string write under an environment key scoped to the specified building and its settlement. Arguments are the building, the key and the string.

## Usage notes

If the building cannot be resolved, this overload skips the write. The key path includes the game environment, settlement and building. Available dynamic verification covers one specific call; it establishes neither cross-game persistence nor duplicate-key rules. Those storage properties remain unresolved.

## Parameters and return type

**Return type:** `void`

| Position | Type |
| --- | --- |
| 1 | `Building` |
| 2 | `str` |
| 3 | `str` |
