[SOLVED]ConditionSwitch "else" and "None" are posible?

[johandark]

Let´s imagine I have this code:

Code: Select all

$ blue = True
$ red = True

transform positionA():
    xpos 0.5 ypos 0.5
    linear 2.0 xpos 0.0 ypos 0.0
    
transform positionB():
    xpos -0.5 ypos -0.5
    linear 2.0 xpos 0.0 ypos 0.0
     
    contains: #d_legr Only visible if there´s blue.
        ConditionSwitch(points_high and blue, At("ball 02", positionA), #If it´s $ blue == True.
                                    points_med and blue, At("ball 01", positionA), 
                                    points_low and blue, At("ball 00", positionA),
                                    
                                    ## If there´s anything else is Invisible or None
                                    else, (None))

There are 3 different Balls "Ball 00", "Ball 01" and 2 "Ball 02". There are 2 positions "PositionA" and "PositionB", but in this case, I just care about the first position.

The thing is, in this "contain" I would like that whatever is not "$ blue ==True" Becomes invisible or inexistent, so "None".

So... Is there a way to say with ConditionSwitch...?

Code: Select all

else:

    None

Thanks!

"True", Null(). This code means if condition reached here, it shows Null displayable.
Though I don't think conditionswitch in ATL works, because ATL only evaluates values when it's showing or replacing.

Ok... The thing is this works PERFECTLY.

I understand Null() Completely.

But I would appreciate a little more explanation about "True"...

I used this before:

Code: Select all

not blue, Transform("aftermorning04_bg_fittingroom_mast_dass_14_d_legr_wet 02", alpha=0.0))

But obviously Null() is better because it doesn´t load the image and it goes faster.

But "True"? Why does it work? What if There´s a mix of True Conditionals and False Conditionals? It would still work as "else"?..

I don´t get it.. :S

Sorry for my ignorance...

In ConditionSwitch, when no any other conditions are match, it will end up display True condition. Yes, it is equivalence to "else" in this case, if you want to see it that way. No particular reason to think too hard about it. It just made to work like this.

Code: Select all

        ConditionSwitch(
            "points_high and blue", At("ball 02", positionA), #If it´s $ blue == True.
            "points_med and blue", At("ball 01", positionA), 
            "points_low and blue", At("ball 00", positionA),
            "True", Null()
        )

when no any other conditions are match, it will end up display True condition

The main reason, is that if no condition matched, then ConditionSwitch throws an error. So you need at least one condition which is always true. 'True' is always true, so it is often used in this case.

I´ll try to take a look on this web, it looks really interesting! Thanks.
