Hi guys,
Im trying to get COGX and COGY values from RR into my C# but i wasnt able to make it work. Im using;
string COGX, COGY;
COGX = rr.getVariable("COGX");
COGY = rr.getVariable("COGY");
COGXtextBox.Text += COGX + Environment.NewLine;
line to get the values but nothing happens. I actually look for the method and everything seems to be fine. Please help me, thank you.
BTW, i checked API page and RR_API classes but still nothing for me :))

Berk,
You probably need to include more context. You are only showing a couple lines and not saying what the actual problem is.
Are you getting any results in COGX and COGY?
Are you not able to communicate with RR?
Are the results just not showing correctly but you can see them in debug mode? The += part of the code you show is a little suspect ... if it is just a text value box a straight = should do the trick.

Thanks for your reply Steven. The problem is that eventhougt i connect API server, it seems like not turning values. I dont get any values in both variables. When the code comes to the line
COGX = rr.getVariable("COGX"); it just crashes and thats it.
Im using multiple line textbox thats why i used +=.
Thx

Berk,
What module is generating the variables? If it is the Center of Gravity module then the variables have an underscore in them. I.e. COG_X and COG_Y
Where is the crash happening? Which line number and what are the contents of the line?

private void veriOku()
{
RR_API rr = new RR_API();
if (rr.connect("localhost"))
{
//List<string> koordinat = new List<string>();
string COGX, COGY;
COGX = rr.getVariable("COG_X");
COGY = rr.getVariable("COG_Y");
MessageBox.Show(COGX);
//COGXtextBox.Text += COGX + Environment.NewLine;
}
}
Thats the part, i try to read variables. And yes, COG values are generated by Center of Gravity.

Here is some code from an old program of mine that tracks a color.
private void buttonTrack_Click(object sender, EventArgs e)
{
int cogx,cogy,centerx,centery;
int offset = 0;
// int dir=0;
int pan = 0;
// int tilt = 0;
Dimension d = rr.getDimension();
centerx = d.width / 2;// int.Parse(d.width) / 2;
centery = d.height / 2;// int.Parse(d.height) / 2;
if (d != null)
{
Console.WriteLine("center = " + centerx + " ," + centery);
}
sp.Open();
while (true)
{
cogx = int.Parse(rr.getVariable("COG_X"));
Console.WriteLine("X={0}", cogx);
cogy = int.Parse(rr.getVariable("COG_Y"));
Console.WriteLine("Y={0}", cogy);
offset = Math.Abs(centerx - cogx);
if(offset>10)
if (centerx < cogx)
pan --;// offset;
else
pan++;// offset;
Console.WriteLine("Offset={0} new pan value is {1}", offset,pan);
sp.Write("servo 1:" + pan + "\r");
System.Threading.Thread.Sleep(50);
}
sp.Close();
}

Thx Ringo. By your help, i was somehow able to make it work. Now i want to apply Gaussian blur and RGB_Filter and Center of Gravity. But i dont have clue how to set these modules values. For example, the window size of Gaussian blur or the values of RGB_filter as min_hue and hue_hysteresis... Can you suggest me a page or something like that so i can have list of request messages to set them. Thank you :)

Berk,
Easiest way to do this is to use variables in the appropriate fields using something like
[variable_name]
and then use the SetVariable api to change those values.
Alternatively, you can use the module in RR, save the pipeline in a RR config file (.robo) and then see what numbers correlate to what values. I.e. if you enter in 33 for the window size you should see which XML field that is in the saved .robo file by loading it back into a text editor. The .robo files are simple XML text.
STeven.
