[Closed] Hide & Unhide objects dynamically

I find a way, thanks for reading me anyway :).

If you’re interested, here’s how I did that :

Actually my script create a visibility track on each objects who have to switch, just as a “container” for a script controller, with the expression :

ik_fk is the object with the custom attribute “ik_fk”, a float ,min = 0 for ik mode,max = 1 for fk.
Self is the object you want to see hiding and showing at the right time.

[/left]
[left]dependsOn ik_fk [/left]
[left]if ik_fk.baseObject.Custom_Attributes[#ik_fk].value == 0 and Self.isHidden == false then[/left]
[left]([/left]
[left]Self.isHidden = true[/left]
[left])[/left]
[left]if ik_fk.baseObject.Custom_Attributes[#ik_fk].value > 0 and Self.isHidden == true then[/left]
[left]([/left]
[left]Self.isHidden = false[/left]
[left])[/left]
[left]0 [/left]
[left]

[/left]
(this example is for a FK Controller, hiding when the custom attribute “ik_fk” = 0)

note : Obviously you can put this expression on any controller, I choose the visibility track just in order have things logically arranged. In all cases don’t forget to return a value compatible with the controller (0 as float in the last line of the expression).

I Just hope it can be helpfull for somebody someday

I spoke too fast… 🙁

The expression seems to work properly but the scene don’t redraw immediately so the controllers can appear with 1-2 sec delay. Sometimes it won’t even redraw until I move the time slider.

I tried adding a “redrawViewsfont=Courier New” method but it didn’t change anything.[/font]

I someone have an idea or two…

What types of variables did you create for ik_fk and Self?

And what max version are you using? The DependsOn command is obsolete since max 8, and its use should in fact be avoided.

Thanks for the answer martijn

I’m working with Max 8 and 9 (all my scripts have to be compatible with both versions), and ik_fk and Self are nodes variables

[left]For the obsolete thing, I have read that too, but I can’t get the behaviour I want if I don’t specify on which nodes to listen to. Is it ok if I just remove it ? (easy way )[/left]

[left]The code for this particular float script, precising the attribute to listen too :[/left]

 [left]dependsOn ik_fk[b].baseObject.Custom_Attributes[#ik_fk][/b]

 
 
 
 
[left]if ik_fk.baseObject.Custom_Attributes[#ik_fk].value == 0 and Self.isHidden == false then[/left]
 
[left]([/left]
 
[left]Self.isHidden = true[/left]
 
[left])[/left]
 
[left]if ik_fk.baseObject.Custom_Attributes[#ik_fk].value > 0 and Self.isHidden == true then[/left]
 
[left]([/left]
 
[left]Self.isHidden = false[/left]
 
[left])[/left]
 
[left]0 [/left]

Could the use of “DependsOn” pose stability problems or something ?

Not really.
When you use dependsOn, Max 8 and 9 add a new parameter track to the controller’s paramblock to define the dependency. Normally, you would create a variable and stuff the node or controller you want to depend on into it. So in a way, using dependsOn does the same, but in a more “dirty” way.

Ok, so the use of DependsOn is just useless in this particular case and on these Max versions…
I will delete them right know and add the appropriate variables…I love when solutions are so easy

Thanks a lot Martijn and Bobo for your advices,

Cheers
