Sensor
======
A Sensor is used to detect collisions with bricks. Due to performance optimizations, passable bricks (or bricks that are too far off camera) can't be sensed.
*Example*
```cs
using SurgeEngine.Actor;
using SurgeEngine.Collisions.Sensor;
object "SensorToy" is "entity"
{
actor = Actor("SensorToy");
sensor = Sensor(0, -25, 1, 50); // a vertical sensor
state "main"
{
if(sensor.status != null)
Console.print("Got a brick of type " + sensor.status);
}
fun constructor()
{
sensor.visible = true;
}
}
```
Factory
-------
#### Sensor
`Collisions.Sensor(x, y, width, height)`
Spawns a new Sensor with the specified dimensions and having its top-left corner located at position (*x*, *y*) relative to the parent object. A Sensor is either a vertical or a horizontal bar that is 1-pixel thin. Both *width* and *height* must be positive integers, and at least one of them must be equal to 1.
*Arguments*
* `x`: number. The x-position of the top-left corner of the sensor, relative to the parent object.
* `y`: number. The y-position of the top-left corner of the sensor, relative to the parent object.
* `width`: number. The width of the sensor, in pixels. Must be a positive integer.
* `height`: number. The height of the sensor, in pixels. Must be a positive integer.
*Returns*
A Sensor with the specified parameters.
Properties
----------
#### status
`status`: string | `null`, read-only.
The type of the brick colliding with the sensor (either *"solid"* or *"cloud"*). If the sensor isn't colliding with a brick, or if it's disabled, its status will be `null`.
#### visible
`visible`: boolean.
Should the sensor be rendered? Useful for debugging. Defaults to `false`.
#### enabled
`enabled`: boolean.
Indicates whether the sensor is enabled or not. Defaults to `true`.
#### layer
`layer`: string.
The layer of this sensor. This property assumes one of the following values: `"default"`, `"green"` or `"yellow"`. If it's set to `"default"`, then all non-passable bricks and [brick-like objects](/engine/brick) are sensed. If it's set to `"green"`, then all non-passable bricks and brick-like objects are sensed, except the ones in the yellow layer. Conversely, if it's set to `"yellow"`, then all non-passable bricks and brick-like objects are sensed, except the ones in the green layer.
*Available since:* Open Surge 0.6.1
