Trying to understand Unity Units

Yoo hoo,

I have programmed some small games in C++ and Java and have been trying to start with unity a few times the last few years, but haven't come over the threshold to use it for anything. One of the problems i have is that unity goes by units instead of pixels. Is there anyone out there that could give me a good run down about how to relate to them when making my games? Is the normal way to use one unit per tile in a tile based game?

 

Unity by default is 100 pixels per unit, but I never think of things in pixels (maybe that's just me).
Primitive shapes by default are created 1x1 units so that's a decent tile size...?
Hope this helps.

 

Yeah, what Mike said. You can define units however you like; one unit per tile is a very sensible way.

If you're new to Unity and making a tile-based game, you should consider browsing the Asset Store for tile map systems. They will take care of a lot of the boilerplate code for you, and get you up and running much faster.

 

I tend to use something like 128 or 256 for tile games. That way you have POT textures everywhere, which Unity likes.

But generally use whatever makes sense for you art and gameplay.

 

Just wondering, why does Unity like power of two textures?

 

They are easier to compress. Its not a huge deal, but it does help with game size on a big project.
