## Signature

```c
ScrHandle START_EXPENSIVE_SYNCHRONOUS_SHAPE_TEST_LOS_PROBE(float x1, float y1, float z1, float x2, float y2, float z2, int flags, Entity entityToIgnore, int p8);
```

## Parameters

- `x1` (`float`)
- `y1` (`float`)
- `z1` (`float`)
- `x2` (`float`)
- `y2` (`float`)
- `z2` (`float`)
- `flags` (`int`)
- `entityToIgnore` (`Entity`)
- `p8` (`int`)

## Returns

`ScrHandle`

## Description

Does the same as 0x7EE9F5D83DD4F90E, except blocking until the shape test completes.

## Usage

### Lua

```lua
local retval = StartExpensiveSynchronousShapeTestLosProbe(x1, y1, z1, x2, y2, z2, flags, entityToIgnore, p8)

-- always available, by hash
local retval = Citizen.InvokeNative(0x377906D8A31E5586, x1, y1, z1, x2, y2, z2, flags, entityToIgnore, p8, Citizen.ResultAsInteger())
```

### JavaScript

```js
const retval = StartExpensiveSynchronousShapeTestLosProbe(x1, y1, z1, x2, y2, z2, flags, entityToIgnore, p8);

// by hash
const retval = Citizen.invokeNative('0x377906D8A31E5586', x1 + 0.0000001, y1 + 0.0000001, z1 + 0.0000001, x2 + 0.0000001, y2 + 0.0000001, z2 + 0.0000001, flags, entityToIgnore, p8, Citizen.returnResultAnyway(), Citizen.resultAsInteger());
```

### C#

```csharp
int retval = Function.Call<int>((Hash)0x377906D8A31E5586, x1, y1, z1, x2, y2, z2, flags, entityToIgnore, p8);
```

- 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.
