You did it wrong fixed.[/QUOTE]
I know.. -.- it was just an example.

[QUOTE=Dave_Parker;23665484]print("Found ents: "..(#ents.FindByClass("classname") > 0))[/QUOTE]

[Cubar]

That's the other way, mine was a different way, he probably copied that from some where he is a skiddie, you obviously didn't know, allways are the same way there is no such thing as a ZOMG THATS A BETTER WAY THEN MINE OMFG OMFG OMFG.

[QUOTE=Dave_Parker;23666608]Can for loops even take an else operator?[/QUOTE]
No, they can't. Cubar does, once again, not know what he's talking about.

[EDITLINE]-[/EDITLINE]
Dave_Parker already posted the answer. Minor mistake in his print function (You can't concatenate a string with a boolean just like that), but he got the important part right:

print("Found ents: ", [HIGHLIGHT]#ents.FindByClass("classname") > 0[/HIGHLIGHT])

Oops lol, well i've fixed it now just a silly mistake dumbasses.

Great job in accomplishing nothing, your code still wouldn't work. If there are no entities with the "prop_physics" class on the map, the if-condition won't even be called.
Please stop trying to help until you've at least got the basics of lua.

[lua]
PrintTable(ents.FindByClass("prop_physics"))
[/lua]

if it prints nothing, it didn't find anything :)

Maybe you should learn to write grammatically correct sentences.
