## Usage

### Lua

```lua
local retval = GetEasingCurveValue(t, b, d, easingCurveType)

-- always available, by hash
local retval = Citizen.InvokeNative(0xEF50E344A8F93784, t, b, d, easingCurveType, Citizen.ResultAsFloat())
```

### JavaScript

```js
const retval = GetEasingCurveValue(t, b, d, easingCurveType);

// by hash
const retval = Citizen.invokeNative('0xEF50E344A8F93784', t + 0.0000001, b + 0.0000001, d + 0.0000001, easingCurveType, Citizen.returnResultAnyway(), Citizen.resultAsFloat());
```

### C#

```csharp
float retval = Function.Call<float>((Hash)0xEF50E344A8F93784, t, b, d, easingCurveType);
```

- Float parameters: Lua integers (`10`, or whole numbers decoded from NUI/JSON) are sent as ints and read as garbage. Write `10.0` or `value + 0.0`. The generated JS wrappers add `0.0000001` to non-zero floats for the same reason.
- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
