Well I wanted to do 2 levels of sds actually....I only see one inside a given object when applied....I am still new to this...I have some experience with programming, but this seems foreign to me somehow...I don't know all the keywords and what they do(in laymens terms)????
Well, in your developer guide, in the ScriptObjects directory, you want the structIRiMeshModifiers.html
file. Load that.
I belive you are interested in the: ChangeSSLevel command:
---------------------
HRESULT IRiMeshModifiers::ChangeSSLevel ( [in] int iDiff )
Change subdivision surface level
Parameters:
bszSelection Specify node or '' for current selection.
Returns:
standard HRESULT processing can be applied to returned value
--------------------
so you can either specify the scene node (your object you want to subdivide), or just use two single quotes: '' in order to use the current selection.
Then, in your script, you do something like this: (currently untested, I'm doing this off the top of my head):
// for testing, first select your object to be SS'd
Name1_ = Node.Selection(); // per Dele example
// now the object you selected has a 2nd name: Name1_
// Now SS it!
level = 2; // this is the level of SS you want to set
MeshModifiers.ChangeSSLevel(level);
-------
Something along those lines; be sure to look at the tutorials from Dele, Stan, etc. here on the forums for sample code.

Here's what I would do:
//Select the object (in this example we select "cube")
Node.Select(Space.CurrentScene() + "/Cube")
// Apply 2 levels of SDS to selected mesh
ScriptObject.RunCmd("mesh modifiers package/add subdivision level", "Selection", "", "Strength", 2)
If you wanted to remove 2 SDS layers you could do it like this:
//Make sure the object is selected
Node.Select(Space.CurrentScene() + "/Cube")
//Change the 2 at the end to -2 to remove 2 layers
ScriptObject.RunCmd("mesh modifiers package/add subdivision level", "Selection", "", "Strength", -2) |

Okay, I have a question here dele. I cannot find any information in the documentation about the stuff you have in quotes, like "mesh modifiers package/add subdivision".
Also, I do not find information about RunCmd.
What is your approach to finding information about these commands and script items that you need?
Thanks,

Probably looking at other scripts, that is how I usually get around...but I've not so much time these days. |

The jScript Macro recorder is your friend. :)
I have my object selected and then record adding 2 levels of SDS. The first function is for any selected object. Next function adds one level of SDS twice.
Doing it this way you could apply SDS to any selected object.
Just another way FYI.
// Macro captured 08/14/07 16:12:40
function Execute(params)
{
sel = Node.Selection();
for (i = 0; i < Node.SelectionLength(sel); i++)
{Node.Select(Node.SelectionGetAt(sel, i)); ApplyMacro(Node.SelectionGetAt(sel, i))};
}
function ApplyMacro(selectedObj_)
{
ScriptObject.RunCmd("mesh modifiers package/add subdivision level",
"Selection", "", "Strength", 1)
ScriptObject.RunCmd("mesh modifiers package/add subdivision level",
"Selection", "", "Strength", 1)
} |

Yup, trueBlue has got it. :) I use the Jscript macro recorder very often to figure out how to access stuff. Sometimes it works, sometimes not. But a lot of what I've been able to figure out has been from that.
I do also dig around in other peoples scripts too. Especially the ones the devs make. But most of what I learn is from the Jscript macro. |

I will start to look into the macro recording... |

Hi Folks. I have assembled a very basic introductory tutorial to scripting and the LE. It takes you step by step through the script creation process. It is in powerpoint format, and I have included a free powerpoint viewer from Microsoft.
Please let me know what you think. I feel this will help others get their feet wet and build confidence in their LE and scripting skills.
Enjoy! If you like it more's coming!
Froo
WOW 58 VIEWS ALREADY ON THIS TUTORIAL!!!
See how much we all realize we need LE and Scripting Tutorials which are free?
Awesome... this upcoming "Script Hookup" Meeting on Tuesdays will be GREAT!!!!
Thanks a million for all this Frootee!

Besides using the jScript Macro Recorder as a helper in scripting, I also wanted to point out something else. The Buttons in the Library Browser have most of the icons that are in the toolbars. Insert a button into the Link Editor and look at the commands in the Command and RClickCommand. You will see the differences in the way the Macro records and the real tS7 commands. Most likely why you could not find it in the DG. Lets use the Add SS as an examlpe.
The jScript Macro Recorder records this with a selected object:
function Execute(params)
{
sel = Node.Selection();
for (i = 0; i < Node.SelectionLength(sel); i++)
{Node.Select(Node.SelectionGetAt(sel, i)); ApplyMacro(Node.SelectionGetAt(sel, i))};
}
function ApplyMacro(selectedObj_)
{
ScriptObject.RunCmd("mesh modifiers package/add subdivision level",
"Selection", "", "Strength", 1)
}
8182
And the command in it's button is this:
MeshModifiers.ChangeSSLevel(1)
Note: Sometimes you do not want to have anything selected before recording a jScript Macro for there is different ways to use this tool as well.
Experiment with both ways and see the difference. |

Hi trueblue. Nice! Thanks! I played around with the macro recorder just now and followed your instructions. I do see the difference.
Maybe we should plan to talk about the macro recorder at the next meeting?
Since it is such a very useful tool that may be underutilized? |

Just thought I'd revive this thread.
Prodigy, This One's For You! :banana::banana::banana:
At this past Tuesday's scriptor meeting Prodigy asked if there was a basic scripting tutorial.
This is actually more of an introduction to the Link Editor (LE) but it shows how to get setup for scripting.
BTW if you are interested in writing your own scripts to enhance your truespace experience we hold a scriptor meeting every Tuesday. I usually make an announcement on Mondays as a reminder.
Later!

Yes,
This should be made into a video course on how to integrate macro recordings into scripts that you want to perform certain functions and how to integrate them into the LE.
Limiting the user base in scripting to those with programming experience is a good thing, but tends to alienate the broader user base. |

hey james. Norm made a few scripting courses way back when; I am not sure if the macro recorder is included in the videos though. |

I think I have all the scripting courses, don't recall the macro recorder being covered in any depth. At least how to apply the results to any meaningful way. |

Just want to bump this thread for the new users and new forum members, in case you want to get into scripting and the Link Editor (LE) for truespace. :)
Enjoy!
