How to color network node

Hi,
I want to distiguish two networks by coloring the network nodes...
Any Ideas how to do this in a simple way?

Nico,

The color is pretty fixed in the code. If you have a very dark background (black for instance) the node gets white otherwise it is always black. Maybe the easiest is to do your own thing on the ondraw. In the code Flexsim just draws a point:
glBegin(GL_POINTS);
glVertex3f(0,0,0);
glEnd();

only it compensates for the zooming so that it always looks the same size and it uses the glPointSize to do that.

Hi Steven,
the problem is that if you put your own drawcode to the NN, it loses the functionality to draw connections between the nodes and you can not switch the showmode of the network. It would be nice if there would be something like a color attribute to change and the rest of the NN-functionality would stay the same...

So changeing the color of the NN is not really working, but I can draw something on top of the connections which is also pretty..

In the Ondrawcode of the NN I put the following :



/**colored column*/
treenode current = ownerobject(c);
treenode view = parnode(1);

// If this function returns a true, the default draw code of the object will not be executed.
if(getvarnum(current,"showmode")!=0)
{
double d_width;
treenode t_obj;
double d_length;
double d_winkel;

drawtomodelscale(current);

for(int x=1;x<=nrop(current);x++)
{
t_obj=outobject(current,x);
d_width=0.1;

double d_tc_x = vectorprojectx(model(), xloc(current),yloc(current),zloc(current), current);
double d_tc_y = vectorprojecty(model(), xloc(current),yloc(current),zloc(current), current);
double d_ta_x = vectorprojectx(model(), xloc(t_obj),yloc(t_obj),zloc(t_obj), current);
double d_ta_y = vectorprojecty(model(), xloc(t_obj),yloc(t_obj),zloc(t_obj), current);

d_length = sqrt(d_ta_x*d_ta_x+d_ta_y*d_ta_y);

d_winkel= radianstodegrees(acos(d_ta_y/sqrt((d_ta_x*d_ta_x)+(d_ta_y*d_ta_y))));

if(d_ta_x<0)
{
d_winkel=-d_winkel;
}

drawcolumn(d_tc_x,d_tc_y,0,6,d_width,d_width,d_len gth,270,d_winkel,0,0,255,0);
}
}

Color and width can be changed in the drawcolum command

It should be okay. Try this:

treenode current = ownerobject(c);
treenode view = parnode(1);
drawtomodelscale(current);
drawsphere(0,0,0,.1,200,100,0);
drawtoobjectscale(current);
return 0;

Nico,

This was more or less what I meant, just be sure to return 0; ! and not a 1 because if you return a 0 the standard code is still executed. So just draw the point over the existing point and return a 0.

Just noticed that Jason beats me!
