Not quite, using and is also correct.
Eh...
Yes, I know that...
I'm just so used to use &&, !, || etc., so I can't type with any other way anymore
Even in normal text I sometimes find myself using && instead of
and ;D
OK it returns an error when I put "obj1 && obj2 && obj3" in the condition field of the end trigger - "Error &&:Type expected object, Bool"
What the hell??!!
That's impossible ;D
Altough, I hope you're not using any of those "" quotes in there, other than that this sounds very weird...
EDIT:
Just a thought, do you have some vehicles/men/etc named as obj1, obj2 and/or obj3??
If so, that causes the problem...
