Its me again, with more random ideas.
I have a few suggestions that can make collision a lot better and simpler to use:
1- A "Negative" collision. In other words, the area you select is the only part of the sprite NOT affected by collision. This will make room collision a lot better and easier to do.
2- A multiple box collision option. Instead of using polygons, you can just click and drag to make a rectangle, and you can make more than one of them. This would be really useful for single sprite maps (or even just standard rooms) as well as many other things.
3- This has probably been asked before, but is there any way to implement a feature that will allow you to control things from one layout from another? Such as generating sprites on layout 2 while on layout 1.
Thats all!
For now at least :)
