I know I'm missing something obvious, but how do I link up a button on a brick to run code when pressed?

button on a brick..you want to make a button control work..the properties tab of the button control panel has a place to write scripts..you get the panel when you right click on the actual button when the node is in edit mode..
you can run a boolean with the button to access some code only when its pressed too.[written as script in the properties panel] ;) |

Thanks stan. The boolean button is what I used for my morpher script. I didn't have any problems with that since I could link it to a variable like you mentioned.
Where I'm not following is what script do I type in the properties tab to make it run a function from inside that script brick. |

Jack I meant running a boolean in a regular button so it doesnt stay on.
the script you run is up to you and what you want it to do..as long as the button will handle it.
I use a boolean script in the button to switch on some line of code in the main script.... opens more possibilities....the boolean musr be an attribute in the main script..then switched off in the code controlled by the boolean |

in this project of mine you will find both types of use of the button control..http://forums1.caligari.com/truespace/showthread.php?t=3784 .. |

Lets say I have a function:
function test ()
{
System.Alert("Button pressed.");
}
How do I call that from here:
8174
The script box here seems to use a completely different syntax and scope than the script brick itself. :(

Yup that did execute. Ok so what I need to figure out then is the scope.
i.e. how to reference a function inside the brick from there.

For a button I use this:
Activity.Run('%THIS_NAME%/MyScript')
%THIS_NAME% <- Using this in above is safer in case you rename your panel later where your MyScript resides.
It is suggested that you add a boolean to a Toggle Buttons. |

its not like c++.. that's why I use a boolean called in the button to access code bracketed in a boolean... the bool is from the main attribute list, setup in the main code...you can't access a bool attribute directly with a button control..
trueblue.thats a toggle control..they work differently..they stay on.. |

Thanks trueBlue. You're closest to what I'm looking for. I don't need a boolean. I just want it to run a function from inside the brick when clicked.
I tried:
Activity.Run('%THIS_NAME%/test')
it doesn't give me an error but nothing happens either. :(
We're close to the solution on this one. It's gotta be something obvious.....

I dunno works here, Here is an example. Have the Stack/Desktop open when you select any of these buttons.
Edit: Oooops sorry stan I was writing while you were posting. |

Ok. It looks like the Run.Activity() calls the "execute" function within an object.
For example:
function Execute(params)
{
Node.Value("/Preferences/Desktop", "BridgeSync") = "On"
}
Oh I get it. Activity.Run() only works on command scripts -- not script objects.
Ok. So we're back to the same question of how to scope to get access to functions inside a brick. I think this one is going to have to wait for one of the devs. :( I'll hunt though the developer docs and see if maybe something jumps out at me in the mean time.
I know there are other ways to achieve the code execution, but this is something that should be doable and it's been bothering me for well over a year now... |

Hmm.... I wonder if it's intentional that script objects cannot have their member functions called, since they are "static" objects and meant to process input/output through the linked values.
In which case the correct solution would be to use a separate command script to implement the button press and read the values off the script object, or to re-implement the whole object as a command script...

Developers tell me you can try this (it works here btw):
Program the button with the function then call it like so:
function aaa()
{
System.Alert("button function call");
}
aaa();
The scripting for buttons is sort of isolated from script object code, so no way to simply call a member function from a button. Using this method, you can script the function in button proper and call it from there. |

Thanks Norm, but that won't allow me to access values stored in the script object. :(
So it looks objects with buttons need to be command scripts or have command scripts nested in them. Then use the Activity.Run() function like trueBlue posted.
Also Functions Sets would be useful here as well. Good thing I found this out before I got too far along, since the Exporter brick is obviously going to have to be a command script instead.

Jack thats why I said use a boolean in the button script with the activuty.run(which I forgot to mention) ..your other code must be setup to allow this ..if you don't want all the script to operate you will have to setup more booleans to isolate the main code..put a bool in the start button and use that bool in the main script to isolate it..its not a true function but you should be able to access one that way.. |

Please forgive me if this is considered off topic, it seems appropriate here to me though.
I have need for the ability to have a 3d object with several buttons on it activate a different script in relation to the function of a second 3d object in a scene.
In this case a Stargate (teleporter or server port actuator) is the second 3d object in the scene. The first 3d object with several 3d buttons on it would be the device determining which scripts were to apply to the second model after a button on the first model is left clicked. After left clicking one of those buttons, the avatar would approach the stargate model and a proximity sensor would then apply the previously selected script.
I am thinking that perhaps an array within a script pertaining to the 1st object, and containing the variable scripts of each button could then be linked as input to the proximity activator.
Is there an easy way to do this or a better approach I am not considering?
Thanks,
- Mark / 3dvisuals dude |

Hi 3D, wouldn't it be easier to have an object that contains the button states then have your teleport script select based on the button states?

Yeah, I'm working on something similar 3dvd. I'm making a teleportation machine with selectable destinations for the immersive environment comp.
The way I'm thinking of doing it is to have a script that sends different coordinates into the "Teleporter" script depending upon which button is pressed. Right now there is a script inside the teleportation trigger called "Teleport". That script collects the Avatar location/rotation or the user defined location/rotation and sends it into the "Teleporter" script. So I'm going to alter that script.
I'm going to make it so that it will collect 5 or 10 locations. Then it will have a number input. Inside will be an if/else statement or switch case, that will tell it which coordinates to output based on the input number. Then the 3d buttons will set that input number prior to activating the script. So if the user presses the first button, it will set the input to 1 and activate the script, which will in turn send the first coordinates to the "Teleporter" script. If the user presses the second button, it will set the input to 2 and activate the script, which will then send out the second coordinates to the "Teleporter" script. So on and so forth.
I have to make this script for my own project so I can send it along to you when I finish it if you want so you can hook it up for your stargate. |

Between Vladimir's FnSet examples and using Activity.Run() to access nested command scripts, I think I should be all set on this one. Thanks for the help guys, this has been something that I've been really stuck on for a while so it's definitely good to finally have it solved. :)

Yes! That would definitely be easier! Thanks!
I had a feeling there was something obvious that was hiding from me as I thought about all this, and that's gotta be it! LOL
I think it was Edgar Allen Poe, if I'm not mistaken, that said the best place to hide a thing is in plain sight! ("Murders in the Rue Morgue," I think;))
Thanks Jack, that saved me a bunch of time!:)

Wow! Sounds like we were almost headed in the same direction on that one!
What you are describing here sounds much better and more elaborate than my idea for sure though!
Sorry if I ruined a surprise competition entry for you by my question here, I had no idea what you were up to! This sounds like it will be very useful for sure.
In reading your description above it sounds really great. If there's a possibility, it might also be way nice to have an input node for a bitmap image pertaining to each of the many destinations so folks could create screencaptures (using external editors) of the viewpoint from the eyecam at a given destination and then add them to a button icon pertaining to that destination, so folks could see at a glance which button to click. Maybe that would be good for a future version. What you described above sounds useful for many other things too!

Well, as it turns out I'm really glad you started this thread too! These samples from Vladimir and the many great suggestions in thread will no doubt be very useful reference sources for others in time too.
Sorry if I kind of dragged it all off topic a bit though, but glad it all turned out to solve the issues you were having, as it sure did with mine.

No no, there are no ruined surprises. I do have a few up my sleeve though. Hopefully I can get it done in time. :) Yeah, it looks like we have pretty much the same idea in mind. I'm actually going to have a bitmap displaying the chosen teleportation area too.
I've attached a teleportation trigger that lets you capture up to 5 locations. Then in the script for your buttons you would write the following:
Node.Value(Space.CurrentScene() + "/Teleportation Trigger Select/Coord Pick", "Number") = 1;
Activity.Run(Space.CurrentScene() + "/Teleportation Trigger Select/Coord Pick");
The first line sets the "Coord Pick" script input to the desired number and the second line activates the script to update the coordinates. So on your first button, you would want to enter 1 at the end of the first line so the avatar gets teleported to the first coordinate. On your second button enter 2 at the end of the first line, etc., etc.
This is path dependent so if you change the name of the teleporter, make sure you change the name in the script for your buttons too.

Space.CurrentScene()
I have been scouring the known world for this over past few days.
That is exactly the way to make some scripts a little less path dependent :):banana: |

This is GREAT!!! Thanks Délé!!! You just created a tool here we're all going to have a blast with very soon!!! Just wait 'till you see what I'll be presenting early next Tuesday night and how that will all work with this, you're gonna love it!:D
I have a surprise I've created for everyone which if I have it ready (and I should;) ) I'll be rolling out at Tuesday night's meeting too, and this one will be something we will all love to use too, even Roman!:D
You're making enormous strides here for all of us with all these fantastic new immersive scene development tools of yours lately! I hope you're enjoying that as much as I am 'cause I'm lovin' every minute of it!!! Great stuff!
Thanks!

This will help us all with quick fixes on a bunch of path related mods to make older scripts functional too aside from being a great new default for all our new scripts! Excellent work!
