Title: Dynamically hide part of a sprite.
Post by: SalmonPunch on December 01, 2014, 06:41:51 pm

I want certain pixels of the player's sprite to be hidden if those pixels overlap with something that is supposed to be "Above" him (IE, if he is standing behind a building, and half his body is behind the building, then that half is not drawn. Is there any way to do this efficiently with 2DToolkit?

I know there is Texture2D.SetPixel, but I have no idea how to use it in this context.

Thanks in advance.

You could achieve this with sorting layers and sorting order in the given layer. Or setting the different Z position for the building and the player. I think there something about this in the documentation in the sprite section.

I would prefer the technologically advanced solution since it will save me a lot more work in the long run, but I will investigate layers if I can't get this method to work.

so back to the original question, could I use SetPixel to achieve this?

You could but it would be slow and you will need to somehow find  exactly which pixels to "hidden". And I don't find the SetPixel method particularly nice nor the "technologically advanced solution".

Sorting layers is the preferable solution here, SetPixel is incredibly (unusably) slow.
