You'd use the locate() proc.

var/obj/someobj/exists = locate() in view(src)
if(exists)
src << "/obj/someobj exists within your view!"
else
src << "/obj/someobj doesn't exist within your view!"
thank you mann! but i got this error :
Naruto.dm:141:error: src: undefined var
Naruto.dm:141:error: =: expected a constant expression
Naruto.dmb - 2 errors, 0 warnings

or this

Naruto.dm:133:error: exist: invalid proc definition
Naruto.dmb - 1 error, 0 warnings

or

Naruto.dm:76:error: exists: undefined var
Naruto.dm:135:warning: exists: variable defined but not used
Naruto.dmb - 1 error, 1 warning

That was purely an example, it was meant to be learned from and not pasted into your code. If you don't have the grasp of the language required to figure out what you need to do with that I recommend you stop using some source you downloaded off the internet (a terrible place to learn), and check out the DM Guide and DM Reference to begin learning the language the proper way. Then after you get that down, you can start checking out the resources to get more involved.
