Tilemap layer opacity

[biggo]

Hi there!

Is it possible to control the opacity of a layer in a tilemap? At certain parts in my game, I need to make a wall invisible - thus having it "fade away".

Can this be accomplished somehow?

Not directly, but if you use a different sprite collection / set of sprites per layer, you can override the the material to use use one with a tint parameter which you can tint to fade an entire layer.

I'm not sure what you mean by overriding the material? Could you elaborate a bit?

Also, how can I use a different sprite collection per layer? I don't understand how that can be accomplished?

I don't know how you've got your sprites set up. If each layer has unique sprites, then you can override materials for those sprites (http://2dtoolkit.com/docs/latest/tutorial/multiple_materials_in_a_sprite_collection.html) and then change the opacity on the material. You will obviously need a material that does that, the default tk2dsprite material doesn't do it but one of the Unity transparent unlit ones will.

Awesome! That works perfectly - thanks a lot!
