So with the new overlay stuff, my mind drifts to weather effects...
You could always implement rain by putting an object over the turf, or by using image() and sending it to everyone, but both had pretty big drawbacks.
Now that overlays will be handled as part of the turf drawing, I assume the drawing speed will be much better than the effect from placing an object over the turf.
Oh wow, I was just about to get into a discussion of how to manage which overlay is intended for what, but a check of the release notes indicates that an overlay can be an object (it says object type, but I assume that means an object), which takes care of that.
SO...I see having two weather objects overlaying each turf. One is the "active effect", such as rain or snow falling, and the other could be (this might be tough to make look very good) an image representing the cumulative impact of the rain or snow, such as water puddles or piles of snow.
What should be handled through overlays and what through icon states will be interesting to find out.
Darkness overlays could also be played with...though it might look better to simply institute a "dark" icon state with appropriate shadows and stuff.
Any thoughts about this?
Ooh, one of us could do a Weather Library, filled with objects that can be used as overlays representing various weather states...!
