Answer my "noob" questions please.

Hello guys, I am new to unity and in games generally. I want to ask how some things work.
1.How big can terrain be?
2.Will decreased field of view improve performance?
3.Is it possible to write scripts for unity in C++ instead of C# ? (I prefer JavaScript over C#, and C++ over JavaScript)

PS: Sorry if this is wrong place to ask, I am new here.

 

1. Biggest possible size?? Not sure..

2. It should.. the less visible stuff, the better the performance, also clipping planes - far , control how far camera can see in distance.

3. you can't use C++, but i highly encourage you to try C#, its just great and gets many things done right with clean code.

4. Try using google often, i used to be like you, and i found almost 80% of my personal questions answered before..

good luck

 

Thank you for your help, going to try something out
