Wayan Sidney Sastrosatomo Just. Nice to meet you.

Just calm down.. ok if he did spam, he probably was not aware of your reaction... was some joke ok. let it be.

and besides im still figuring out what the poster said with "This behaviour leads into ugly if-else blocks with code duplication."

code duplication what he means? and how come it executes?
was it supposed to stop on the first condition if ent!=NULL and not check the rest ..or is something different.. im just not getting.

I never though about such situations...

at the moment you need:

if(ent != NULL)
{
if(is(ent, SHOW))
{ [...] }
}

and we want:

if(ent != NULL /*if here this is already wrong, and the && follows, just stop*/ && is(ent, SHOW))
{
[..]
}

It's called short-circuit evaluation:
http://en.wikipedia.org/wiki/Short-circuit_evaluation

oh right i though that could be done already OOLOL, my bad.
That could explain some script behaviours not doing okay, and i though was my fault.

I had the same prob some days ago, so I would appreciate this short-circuit evaluation thing.

I too am STILL waiting on the short-circuit evaluation to be implemented...

I grow tired of using work-arounds like
because there is some you just cant do...

Would like to have it too.
Always need an extra IF-block for checking if an entity is valid v.v(tooo many brackets)

I hope it's possible to change it anymore because I would really like to see "short-circuit evaluation", too.

Seconded.
