hide/show objects dynamically in presentation mode

April 5, 2011 | 2:13 pm

hello,

using the different objects to design an interface using the presentation mode, I’m comfortable with fpic, playing with alpha & presentation_rect to hide, move etc.

Using jit.pwindow too, I can I play with it dynamically?
I don’t mean to load new movies etc.. I’m ok with that
I mean about making it … invisible?
I thought about sending into it the message (presentation_rect -20. -20. 10. 10.) in order to put it outside, BUT I’m afraid in standalone, it shows scrolling bars or something like that..

any tips? trick?

how about taking a panel with the same color as the background and put it over your pwindow? then all you need to do is play with bringtofront and sendtoback in thispatcher to either show or hide it.

you can set the object’s @presentation attribute to 1/0 to show/hide in presentation view:

MIB, I have special background, not solid color so I cannot use that; thanks.

Ben, didn’t even know that.
combining that + another presentation_rect message (because presentation 0 modify to patcher_rect) is FINE!

thanks to both of you :)

working on it, went further.
all seems to work very fine.

I chose another way to do that.
Using a lot of JS as a core of a lot of systems I designed, I’m using the method: this.patcher.message(); to address directly objects on the patcher.

Just wanted to put it here, in the case others find that on search engine.
Indeed, scripting Maxobj from JS works very fine.

Good one…
the only issue with the

toggle > presentation $1

is that the position and size of the object in the presentation mode aren’t recalled because it will basically be withdrawn and re-added to presentation. The simple use of the

toggle > attrui (hidden)

hides the object from the presentation without altering its properties within it.

haven’t pasted a max code before, hope this works:
