Real camera Smooth Follow

Camera & Cinematics Camera
1

Hello there !

i have a problem with my smooth-following camera:

i play a crate that is in third person
a camera is following it with the script Smooth Follow
Crate can rotate using mouse

but here is my problem : how can i make that the camera cant go behind walls ? it doesn’t work with collider :roll:

Look this Topic about Wow Camera,
http://forum.unity3d.com/viewtopic.php?t=18073

the result that I liked most was:
WowCamera.cs

but I have a problem in it.
Can somebody help me in my error?

the js and cs script doesn’t work very good :stuck_out_tongue:

I like the way the trees straighten when you get near them. its like they’re slouching and then stand at attention when they notice you approaching. :shock:

5

I dont understand.
you say that i dont can use Javascript and C# in the same Project ?

This is the Movimet Default of Tree in Unity. :stuck_out_tongue:

6

Of course, you didn’t know that ? :slight_smile:

7

o.O
i didnt know :shock:
humm, then the cause of my error is this.

i will try convert all my scripts to C# and test.

thanks friend.

please, if you have one camera Script same Wow, Perfect World, and if can share, i want ^^

8

lol, he was kidding (see the smiley face?) You can absolutely use Javascript and C# in the same project, no problem.

:?
i am confuse now.

anyway i am studying the new tutorial released in unitytutorials.com:
EVAC-CITY Tutorial
is amazing, i am learning very much ^^
http://www.unitytutorials.com/document/298/how-to-make-a-game-similar-to-evac-city-in-unity3d

but i somebody have any Camera same wow, perfect world, please share to we ^^

No !!! You can use c# and java script togetheer. Obviously…

not as well really, since one has to be compiled before the other if using get component. but thats easy to do if you put the first in the standard asset folder
