Isometric City Builder Game

Unity Engine
1

Hello everyone!

I´m working on a city building project.
It´s a web browser game on City Ville style, so the view is isometric and the graphics 2d to save on size.
I´m using Sprite Manager 2 to create the sprites but don´t know how to set then on the terrain.

I use a ortho camera rotate on 30 45 0 to have the Iso look, but jus´t can´t get the sprite to stay on the right position, it´s just float above or below the terrain.

Other problem is how to work with the colision detect. I bought the RTS PRO PACK, wich gave me a nice idea of how to build a grid to locate the objects on the terrain, and to build then. But can I use it on 2d?

The problem is, how should the terrain be design and positioned relative to the 2d objects, and how I split it in tiles/grids to know where the objects/mouse are??

Quite a big post… I have search around, but not find clear answers… hope you guys can help me! I´m brazilian, so sorry about my english.

Many thanks, and kind regards.

I was thinking, maybe we can do a Cube and assign textures to it, something like Simcity 4??

I found out that using 3d it´s way easier, but the problem is that I can´t make a object that has a good file size, everything is at least 80kb (after I made a prefab).
I think that for a browser game the buildings should have 10kb at top??? So 2d it is… still the same problems though.
I create hundreds of game objects for the tiles, on mouse over they lit up, and I can replace then but the building when I click. Snap to grid to move objects… and prefabs with the 2d objects attach to tiles.
What do you guys think, any ideas?

It would be easier to make smaller file sizes with 3D graphics. For simple cube-like buildings, the mesh is little more than a few bytes, plus you could tile the texture easily, so you could have smaller texture sizes.
