convert boolean true or false into float in a float script controller?

[Anonymous]

Hello friends, here I am with noob questions again.

My need is simple: I want to switch controllers in a list on or off using a custom attribute with a boolean checkbox.

If I debug the float script, i can see that switch (my variable) evaluates to true or false.

So what I'm trying is:

if switch = true
then 1.0
else if switch = false
then 0.0
else switch

The script evaluates to 0.0 no matter what the switch is set to.

Why doesn't this work? Thanks in advance for your time.

= is for assignment, == is for tests. You need to use == in your example.
Also, you don't need to test for equality - "if switch then" is equivalent to "if switch == true then".

Your code, assuming you're using the Checked property, makes no sense as "switch" can only ever be true or false - you only need one test, but you're catering for 3 conditions (which would only be correct if you used Tristate instead of Checked, but then the tests would be incorrect as Tristate is an integer, not a boolean).

Thanks very much, Steve. I tried this:

if switch == false
then 0
else if switch == true
then 1

And  it's evaluating 0 or 1. I think the info about == being for tests made the difference.

Great forum. Thanks again!

You still only need one test:-

if switch then 1 else 0
-- or
if (switch == True) then 1 else 0

Or

if (not switch) then 0 else 1
-- or
if (switch == False) then 0 else 1

You don't need to test both conditions because failing one condition means the variable is, by definition, the other condition - booleans can only have 2 states.

Ah!

Ok thanks, Steve, putting that in the memory banks now. Much appreciated.
