Thread Split: Some posts in this thread have been moved here

Hi Brian,
I used the bounding box in my original trials but wanted to use the intersect node to give a more accurate layout (allowing for nesting within the bounding box). My problem is to find away of using the output of intersect node as a true or false or 0 or 1 so I can then trigger the movement.
I looked at the JS code of the intersect node to see if the output could be changed to give a 0 or 1 and then create a new node but my limited JS knowledge is a problem hence my post.
Cheers
Barry

Instead of factory.commit(), putting the intersecting lines/curves/points in the geometry database,
objList = factory.calculate() would put the curves & points in an objectlist, which could be counted/ checked for length.
I'll defer to the professional programmers, due to my very limited knowledge, and limited time :-)

Hi Barry, it looks like you'd need to do 2 things - you'd need to change the output type of the node which is defined by this line in objIntersect():

this.addOutput("Out","objectlist");

It sounds like you want it to output a boolean value, it looks like you can put in "boolean" for that, so change that to:

this.addOutput("Out","boolean");


Then to actually make the boolean value you will need to change the onExecute function for objIntersect, the last line currently looks like this:

this.setOutputData(0, output);

To change that to a boolean value instead of outputting the object list try this:

this.setOutputData(0, output.length > 0);

So that should then output true if anything was generated from the intersection or false if nothing was generated.

Does that maybe do what you need?

Hi Michael,
yes that’s what I need to achieve a node that indicates a collision.
Thanks a lot.
Barry

Hi Michael,
I modified Max's node as your suggestions but cannot find anyway to connect it to the maths node.
Is the output a numeric number ?
Thanks
Barry

---

Hi Barry, the output for that case is a boolean value, not a number value. But if you want a number to be output instead, try switching the output type to:

this.addOutput("Out","number");

Then in onExecute, try this:

this.setOutputData(0, output.length == 0 ? 0 : 1);

The "output.length == 0 ? 0 : 1" part is a compact way of saying: "if output length is 0 output 0 else output 1".

Hi Michael,
changed code as your reply only thing had to change was "number" to "numarray".
works just as I needed so again many thanks for sorting it for me.
Cheers
Barry

Hi Michael,
I was a little premature thinking by altering the this.addOutput(“Out”,”number”);
to this.addOutput(“Out”,”numarray”); worked, it only allowed connection to maths node but the maths node does not recognise the input. So back to square one.
Any more ideas gratefully received.

Animate going easy..



Just take the 3 axes from the 3dm file -> place it over the axes points of your favourit piston > name the parts like in the 3dm file -> open nodeeditor with the nod file -> press play and enjoy...

runs fine on nodeeditor @'y'@ 0.99 without any special extensions....

Hi Barry, well I'd guess numarray would need an array of numbers to be returned instead of just a single individual number.

In Javascript you can make an array by using [], like [ 'a', 'b', 'c' ] . So try changing the onExecute part to this:

this.setOutputData(0, output.length == 0 ? [0] : [1]);

...easy to use your tricky Nodeling ...but maybe not so easy to create it from zero! ! ;)

There is a (minor) difference in the behavior of the concat2 node in MoI4beta.
It is a failure to release the mouse attachment to the node, under certain circumstances.

By clicking RMB on top of the concat2 node, one of three input configurations may be selected,
called Numbers, (numarray), Points, (pointarray), or Objects.
This should be done before attempting to wire the input with the wrong type.
In MoI4beta, "Dragging" a gold wire for Objects to the wrong input, Numbers or Points, and then pushing RMB and selecting Objects,
results in the proper input being changed to, and the wire attaches, but the mouse is then locked onto the node box.
The only way I've found to release the lock is to press ESC, and reload the file.

This does not happen in MoI3. Clicking the RMB releases the attempt to wrongly attach the wire.

Hi Michael,
that’s seem’s to be the answer.
Many thanks.

<< ...easy to use your tricky Nodeling ...but maybe not so easy to create it from zero! ! ;)

EASY!

1. reinvent the cosinus
2. discover javascript
3. enjoy nodeling
4. keep nodeling

There is still a more EASY version:

>>2: Discover Javascript
Step 2 is maybe the pitfall hurdle obstacle stumbling block! :)

PS Nodes used are all native nodes renamed ?
As I have yet translated all native nodes in French that will be cool if you have a version with only native ones! :)
For example I don't see "CrankL" in my native list!



I follow this guy every day, day after day, but only for the pleasure of the show! ;)

Uuuuups..

With the Animator 10 in French native

---

Animator 11 works very fine!
As you can see i must translate all! :)
Here just translated the "-Limit"!
Look "- Limite" and "+ Limit"

in fact i was too speedy I must translate in French like this "Limite -" :)



Can we have a look of the code of the macro is ?

So a very big metaphysic problem for me : must i translated all nodes or only nodes that please to me! :D

---

<<<(and i put Speed 2 : because we have only one life (not like cats who have nine! :D

var LengthOfLive=moi.GetDistance(birth,death)/speed;
if(speed<=Math.PI/2){break;}else{return;}


PS translating the nodenames makes only sense for the nodelist... if you have a LOT of nodes you have to give them relating names......

---

So the French version :)
But no exactly complete because you hid some nodes that i discovered in moving some ones !!! ;)

<< PS translating the nodenames makes only sense for the nodelist

Sure and for the Anglophobic user who has the illusion to understand a little bit of what's happening on the screen! :) :) :)

PS Thx for the Macro : indeed 2 lines can animated the world! :)

So 2 missing! (will be complete on my site! :) http://moiscript.weebly.com/elephant-systegraveme-nodal.html
