Methods
read(tile) → {number}
A function to read the value of the light sensor. It will use the read
function from the AnalogLightSensor and compare the value to the
thresholds.
Parameters:
| Name | Type | Description |
|---|---|---|
tile |
World.Tile | The tile to read |

Returns:
- 0 (black) or 1 (white).
- Type
- number
setThresholdDown(threshDown)
A function to set the down threshold. This will constrain the value to
between 0 and 1. If the threshold is higher than the up threshold then
they will be switched.
Parameters:
| Name | Type | Description |
|---|---|---|
threshDown |
number | New threshold. |
- Source:
setThresholdUp(threshUp)
A function to set the up threshold. This will constrain the value to
between 0 and 1. If the threshold is lower than the down threshold then
they will be switched.
Parameters:
| Name | Type | Description |
|---|---|---|
threshUp |
number | New threshold. |
- Source:
swapThresholds()
A function to swap the thresholds if threshDown is larger than threshUp;
