new WayDeterminer(transparencyColoropt, canvasObject, arrayOfCanvasObjectsopt)
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
transparencyColor |
Number |
<optional> |
0 | The pixel color value denoting clear, default is 0. |
canvasObject |
CanvasObject | the CanvasObject to use during wayIsClear calls. |
||
arrayOfCanvasObjects |
Array |
<optional> |
optional array of CanvasObjects to use during multipleWaysClear and multipleWaysClearAndRegister |
Members
(static) bitmapData :CanvasObject
The CanvasObject to use during wayIsClear calls. Whatever CanvasObject is set during construction overrules this value, but this value is not a reference to what was set during construction.
(static) transColor :Number
The pixel color value denoting clear pixels, default is 0.
- Number
_bmdRef
Set during construction to the CanvasObject you pass.
_lastBitmapHit
Set during multipleWaysClearAndRegister
constructor
multipleBitmapDatas
Set during construction.
Methods
multipleWaysClear(x, y, bitmapDatas) → {Boolean}
Returns true if the pixel color value in each CanvasObject in the bitmapDatas Array matchs WayDeterminer.transColor or 0.
| Name | Type | Description |
|---|---|---|
x |
Number | The x location to check |
y |
Number | The y location to check |
bitmapDatas |
Array | Array of CanvasObjects to check, if not set the multipleBitmapDatas property will be used. |
- Type
- Boolean
multipleWaysClearAndRegister(x, y, bitmapDatas) → {Boolean}
Checks the x y position on each CanvasObject in the bitmapDatas Array. Returns true if the pixel color value in each CanvasObject matches WayDeterminer.transColor at the given x y location. If the way is not clear this method sets _lastBitmapHit to the CanvasObject that was not clear at the location.
| Name | Type | Description |

x |
Number | The x location to check |
y |
Number | The y location to check |
bitmapDatas |
Array | Array of CanvasObjects, if not set the multipleBitmapDatas property will be used. |

- Boolean
wayIsClear(x, y) → {Boolean}
Returns true if the pixel color value in _bmdRef or WayDeterminer.bitmapData at the x y location given matches WayDeterminer.transColor or 0.
| Name | Type | Description |
|---|---|---|
x |
Number | The x location to check |
y |
Number | The y location to check |
