## Description

Three actions that let a browser-source overlay talk to Streamer.bot: one that  
sends a line to chat, and two that book viewer points and read balances.

The point actions are silent and work alongside **Currency Core** : they write  
the same persisted user variable (`points`), so your existing point commands  
keep working exactly as before, with their usual chat lines.

I built them because Currency Core posts a chat line after every booking. That  
is fine for a single reward, but an overlay that sells 32 bingo cards writes 32  
lines, and deductions read as “adds -100 points”.

| Action | What it does | Arguments |
| --- | --- | --- |
| `Overlay Add Points` | books an amount (sign included) and confirms it | `input0` = amount, `input1` = login, `requestId` = your id |
| `Overlay Get Points` | reads a balance and broadcasts it back | `input1` = login, `requestId` = your id |
| `OverlayChat` | sends a supplied line to chat | `text` |

### Why the answer comes over the broadcast

Streamer.bot’s DoAction reply only confirms that the action was started, never  
what it wrote. So both point actions answer over the WebSocket broadcast with  
the `requestId` you sent:

- `Overlay Get Points` answers `{"requestId":"…","points":1200}`.
- `Overlay Add Points` answers `{"requestId":"…","booked":true,"points":1100,"reason":"ok"}`.  
That answer is the point: an overlay can charge an entry fee only once the  
booking is confirmed.

`Overlay Add Points` also **refuses** a deduction the viewer cannot cover  
(`"booked":false,"reason":"insufficient"`) instead of writing a negative  
balance. Nobody ends up at -49800 points after betting more than they had.

## Installation

In Streamer.bot click the `Import` button in the top menu. Drag the **.sb** file  
into the `Import String` field.

The three actions land in a group called `Overlay`, next to whatever you already  
have. Nothing else to configure.

You also need the WebSocket server running (`Servers/Clients` → `WebSocket Server`),  
which is the same server any browser-source overlay talks to.

If you already have an action named `OverlayChat` from setting this up by hand,  
delete it before importing. Otherwise two actions share a name, and DoAction  
addresses actions by name.

### Updating

To move to a newer version of this package, delete the `Overlay` group first,  
then import. Importing over an existing action keeps the inline C# code that is  
already there, so the actions would still be named right and still behave like  
the old version.

## Configuration

Point your overlay at the action names. In our overlays that is four lines in  
`config.js`:

```js
outputSource: 'streamerbot',
streamerbotChatAction: 'OverlayChat',
streamerbotPointsAction: 'Overlay Add Points',
streamerbotBalanceAction: 'Overlay Get Points',

```

Any overlay that can call DoAction and listen to the broadcast works the same  
way. Here is one of ours paying out in OBS:

## Commands

None. All three actions are meant to be called by an overlay through DoAction,  
not typed in chat. Your Currency Core commands stay as they are.
