en that name). For example, in my grammar:
F = FXX = %(50:F[-X][+X]; 30:F[-X][X][+X]; 20:F[X])Axiom => F0 - F1 - FX2 - FF[-X][+X] with some seed, or FF[-X][X][+X] with other seed, or FF[X] with other.
And context-sensitive means, for example in my grammar, the rule:X = >(-F:+FX; +F:F[-F[-X][+FX]]) if the previous symbols (in the string of L-System, on the left when a X is read) is a -F, then X will be +FX, but if the symbol is +F, then X will be F[-F[-X][+FX]].
Or:
X = G(2: +++F; 3:++F; 4:+F) means that in the second generation X will be +++F, in the fourth will be +F.
Or:
X = IF(BL = 3: +F, -F) It means that if the branch level (BL) of X is 3, will be +F, otherwise -F.
And parametric is something like:
F = F(ValueA:x+0.5; ValueB: 6*BL), F have two metadata (ValueA and ValueB), and when "x" is read, is replaced by the value of that attribute of his predecessor, ie, will be the ancestor valueA+0.5. And BL is the branch level of X, which means that if X have a Path like {0,0,1} or {0,3,0} (three indices), ValueB will be 12, for that X in that generation/iteration.

esn't do just that. I have 3 inputs which contain curves, one of the inputs usually has <null> items in it, so I am trying to filter out those nulls. The 3 inputs have different amounts of curves in them, normally one of the inputs is grafted as well.
So one would assume it just gets rid of the nulls and thats it. Well it doesn't. In my case it simply takes the curve from the first input (1 curve) and copies it 20 times (the second input contains 20 curves). The nulls are gone, but so are 19 other curves!? Maybe I don't understand the component properly, but its not doing what I am expecting.
Using a Merge component works as expected.
I am aware of checking for Null Items and using Dispatch, but I thought Combine Data is exactly for that purpose!?
Flattening the inputs makes no difference.

e length from center point to each vertex related to time, and make them roll on ground under gravity.
I have created the model with 1 center point and 12 vertex points using GH, however when I convert particles for Kangaroo and apply gravity, I faced several problems and have several questions related to that.
Problems are:
1. 13 particles does not keep the shape of icosahedron and just fall flat on the floor.
2. I have managed to keep the shape using multiple "Tetrahedral Element" component, however this component determines its shape by its starting point so I do not get to control the length from center point to vertex later.
Questions are:
1. Is there any way that I can restrain the relative coordinate of vertex particle from central particle using its angle and distance?
2. Is there any way that I can control the parameter for distance relative to time?
3. Is there any other component I can use or any advise you can give me about how my simulation can be achieved?
Regards.

al read” component in grasshopper.
But somehow it seems that the command line “TempSensor.requestTemperatures();” makes the firefly firmata somehow unstable. I have also connected 5 servo motor which move strangely irregular/wrong when the command line above is in the program. So, when I for example only control the "Digital Pin 12" in grasshopper it mainly moves the servo on Pin 11 (!) but also a bit time delayed the servo on Pin 12.
Do you have any ideas? It has to be something inside the “#include <DallasTemperature.h>” (Libary for the temperature sensor) which doesnt go together with the firefly firmata und gets something wrong in the "void WriteToPin" firmata command
Or do you may have any working codes for implementing a temperature sensor? Its doenst have to be the one i have, I could get another one.
here you can see the code: http://txt.do/drqao (a simplified version of the latest firmata including my TempSensor lines marked with "//...//TEST")
Thanks! Julian…
r day, at 10 12 and 15, also summer and winter holidays should be considered. To set up this occupancy file, the component was plugged in shown in the screenshot. However, the generated csv file doesn't give me what I expected, occupancy written as 0 in days from January to June.
Could someone tell me a way to solve it?
I could generate two csv files by plugging in only one analysis period each time and manually sew them in excel, but I am sure there is better than that.
Thank you!

est of the year so I'm trying to understand new things...
I downloaded Boids by Jan Pernecky and tried to do something like the flocking 2d pattern of this amazing video video (2:41) but i'm not very happy with it. You can see the first result on this image.Image of the code
For now, I have 3 groups of 3 circles with 12 points on each: blue circles (points) are used for the "Adhere" flock location and the red ones for the "Repulse" flock location.
After, I cut the whole thing with the wire-frame of the bounding box of the emitter of the points and their mirror according to the center axis of the central circle. (red rectangle on image).
First, how can i contain the curves into a region ?(without the bounce component because it's very slow...)
I think to have a result like the one in the video, i need many other forces ? I didn't understand the "finesse" of the flocking concept...
Is there a way to trim vectors but not just by speed but by angle or to replace them ?
I tried to put more forces like the "align" but results are bad for now: curves are too flat or not aligned at all.
The * parameter is also hard to manipulate (for nuts like me hehe): for example, my repulse forces are kind of not existing or too strong... ?
How can i use the stick geometry component with other behaviours on the same time ?
It will be very nice if someone can give some advises or share some codes to help me... first time I use agents in grasshopper...
Thanks in advance.
Peace.
Sorry for my frenchy English.
