Thanks for the reply guys!
@shinkan Yes i requested a shader like that to Gigatron that did this one:
(That i guess does the same as yours. )
The problem was that on sprite animations on export(due spritesheeting) , the shadow overlaping with other objects and the shadow rotation on sprite rotation changes.
But as you pointed, adding the DropShadow to the layer works perfect! even with animations on expored!(no mater spritesheeting anymore) and the shadow is always on that Offset, no matters the sprite rotation .
@Magistross Thanks for the updated .capx maybe in some cases i will hade to do in this way to have more control over the shadow. BTW, you again add an event to each sprite that needs shadow, that is like give shadow for each srite one by one. If i have 50 enemies i will have to make 50 events... the idea was make general, so simply add the sprite on the Shadow family and this one gets shadows automatically, without add into events.
@SoldjahBoy Yep! i know, but you have to use containers, add for each sprite a container with a shadow,etc... i was looking a more automatic process. Now time to test better all this but seems is working that i need.
