HI,

I have a problem I've dealt with in max, using an "if" object. I always assumed there was one in Pd, but I can't find one.

I'm trying to resolve this with regular vanilla type objects, but the solution is escaping me.

I have 5 number boxes, each one is sending mostly 0. When a non-zero number comes from one of the number boxes I want that to be output, and all the zeros be ignored.

In Max, in my "if" object I have this:

[if ($i1 == 0) && ($i2 == 0) && ($i3 == 0) && ($i4 == 0) && ($i5 == 0) then zero else out2 $i1 $i2 $i3 $i4 $i5]

The object has 5 inlets and two outlets, one for zeros and one for all the other values.

I guess I could do this with a [sel 0] object and take the right outlet, to filter out all the zeros. But just curious if there is a more elegant way someone can think of.

Thanks, nick

@nicnut [sel 0] is very elegant and simple.
Otherwise you would use a far too complicated [expr] to do the same as you had done in Max.

@whale-av thanks David. I guess it's called expr, that's what I was looking for, I ended up using several [change] objects and [sel 0]. It seems to work fine. But just wondering if there was an "if" object, but I think that's what expr is.

@nicnut Yes. [expr] gives you if statements, and they can be nested.
Each separate statement within [expr] gives you an outlet.
I don't think you need [change] as every incoming message will be separately banged through..... and so just [sel 0] being fed from all your number boxes will do the same as the Max "if".
David.
