The OTLineElement

The  OTLineElement is an orthello element that lets you create all kinds  of lines using orthello sprites. A line can have one or more unerlying sprites that will be stretched between a start and end point. Using a OTFilledSprite with a scrolling value you could even create a scrollable line, as seen in the demo.

In the editor the pivot point of the line is always on line.start and you will have to set line.width and line.height to adjust the line. the underlying sprites will be automaticly adjusted.

When changing the line by code, the regular approach would be to use line.start and line.end to set the start en end point.

!IMPORTANT To be functional, the OTLineElement needs to have a localscale of (1,1,1). If you would like to alter the appearence of the line, use the sprite childs within the line element.

!IMPORTANT Also ... the OTLineElement must be located in your scene's root or in a parent located at 0,0,0 and has a 1,1,1 world scale ( so towards the root of your scene ).
