<p>Hi,</p>
<p><br>
</p>
<p>When using environments like class rooms in worlds and creating user interactive programs, what is the best way to prevent a user driving a character or camera through a wall. Is there collision control? Thanks for suggestions and if you can attach files
that would be great.</p>

<p>Thanks!</p>
