I'm starting experimenting with Command & Conquer Red Alert 2 -type isometric game with Unity for mobile devices and started to think if 2DToolkit would be helpful in creating that desired outcome. Isometric games have been discussed here before but some questions still baffle my mind. Actually my questions can be seen in this screen shot:
1. Does 2DToolkit support movement on Z-axis (if tile map ground is laid in X - Y), or in this context would it be possible to create flying units? I think having an own layer is the key, but I'm also thinking of those shadows, that they would still be cast on the right tile (f.ex. where the bombs would be dropped)?
2. Buildings and trees that units can go behind to and in front of, but which also have collision detection? Does 2DToolkit determine automatically which sprite is drawn in front of another (in case of vehicle being behind a tree and in front of it) or does this involve some kind of layer witchcraft? Also, would the collision detection be done in so that box/sphere collider would be created for each object?
3. Height variations. Is it possible to create varying heights in tile map and have some tiles to act as slopes which units can pass, or cliffs which work as barriers?
