I'm sure this is quite an easy one for all you trueSpace scripters out there but I'm not very knowledgable when it comes to trueSpaces non-modeling features so I was wondering two things:

1, how do I link an object to another objects transformation so it sticks and moves along with that object without rotation?

2, how do I link one object to adopt only the rotation of another object? but leaving its position unchanged?

If I could, I'd create some sort of object-linking tool where I could set an objects x,y,z position and x,y,z rotation all separately by simply selecting the object I want to link to from a drop-down list of all the objects in the scene.

Kind of like:

Rotation:
[x] = [object_02<]
[y] = [none]
[z] = [none]

Position:
[x] = [object_01<]
[y] = [object_01<]
[z] = [object_01<]

Perhaps something along these lines is already in the program. I just don't know about it.

You can have a look at these old scripts:

Wow, from the pictures on your website that looks pretty much exactly like what I was looking for! I'll give it a try! Thanks!

Loving the script so far! Is it possible to add the script to a button? and maybe have piece of text in the properties of a constrained object that tells you which objects it is constained to?

I'm sure all sorts of improvements are possible, but it would be extremely low priority on my todo list. The last change was way back in 2008.

If Clinton does not mind, I'll try to incorporate them into the Unofficial Update!
Because those are some very awesome tools!

Don't be silly, of course I don't mind.

Would be awesome to see this further developed, maybe with a point-object rotation in direction of linked object kind of function!

I was trying to use the script for animating this turret:

Maybe this thread will help. Lots of Link Editor help with objects.

Oh yeah! I remember that! Although I can't find any links in this thread with how he actually got all that to work. He said it was simple... everything is simple once you know and understand it. haha

I miss Prodigy.

Here is what I have come up with so far.
No code changes.

: Capture.PNG (6.36 KiB) Viewed 3593 times

Added:
Short names to the UI.
Floating panel

Dabbled at removing the pWeight con(s) with the UnDoIt with no luck.
Seems that the pWeight(s) can be created endlessly.

Don't forget, one object can have several constraints assigned to it, so it can have more than one weight.

I have it on my Desktop.

You do not mention anything about the preStore and buttons.
I assume the video was created before the above addition.

Sadly, I had to remove your Constraints script from the Unofficial Updates.
This could be a very valuable tool for trueSpace!
Maybe I am not using it correctly.

Currently there is several errors with your current unmodified scripts.

The theNode script called from the Sendit object seems be missing:

Code: Select all

Activity.Run(Space.CurrentScene() + theNode);

pWeights do not seem to work and are not flagged IE: What is? (pWeight, 1) (pWeight, 2) and What do they do?

Cleanup (unDoIt) does not work and there is errors

Constraints

Wish List
Auto Popup Floating panel

User Interface
Buttons to select the Controller and Controlled objects and works with Add and Remove.

Constraint panel has the UI exported to the Controlled parent

Controller (constrainor) and Controlled (constrainee) attributes exported to the Constraint panel

pWeights exported to the Constraint panel (Not to the parent panel),
with the chected flags IE: XR, YR, ZR

General Constraint script with some fixes.
changes from the 2008 version on my website are
fix - extra matrix connection was being made for each controlling object
removed the exports for the weight connectors and instead exported the entire constraint node. this makes all the values visible in the side panel and connectors don't need to be removed when the constraints are removed
fix - zero value for weight now has no influence when only one controller is applied

Still has the same limitation as the original. It uses command scripts which are not compatible with rendered animations without first baking the animation down to keyframes. I plan to make a version that does work with animation by using object scripts instead. Object scripts are more limiting in that the controllers and the controlled will have to be at scene level, not in a group and the number of possible controllers will have to be a hard coded value instead of unlimited.

Yay! Thanks!
One thing that I noticed when using this, the Constraint inside your General Constraint script can be deleted and then causes an error.
unDoIt
Add

Code: Select all

var constraint = System.ThisOwner() + "/Constraint"
	if(Node.FirstSelected() == constraint)
		return;
var Constraint = System.ThisOwner()
	if(Node.FirstSelected() == Constraint)
		return;

This version will render without the need to bake keyframes of the constrained object. It only works with scene level items. It does not work inside a group.
