Drag and drop with rotated sprites

Recommended Posts

Hi,

 

I'm relatively new to Pixi.

 

I have a problem similar to the one mentioned in this post:

http://www.html5gamedevs.com/topic/5766-bunny-drag-example-with-correct-mouse-offset/?hl=%2Bdrag+%2Bpixi

 

I used the code from the post and it worked seamlessly. However, when i began rotating the Sprites the offset became wrong, and the sprite jumps to another location when i begin dragging it. Do i have to use some trigonometric function to reverse the rotation? How can I do this?

 

Here is a version with rotation:

Here without rotation:

Thanks in advance!

 

Felix

I think this is because you are using the value returned by calling the 'getLocalPosition' method of the interaction data. If you just use the iData.global property instead that gives you the position of the interaction relative to the stage, thereby ignoring any rotation transforms applied to the sprite itself.
