i use this method to draw a line through some points:
public void connectBoxes(ColorRGBA colorUsed, String author) {
MaterialState ms = DisplaySystem.getDisplaySystem().getRenderer().createMaterialState();
ms.setColorMaterial(MaterialState.CM_AMBIENT_AND_DIFFUSE);
int length = boxes.size();
Vector3f[] vertex = new Vector3f[length];
ColorRGBA[] color = new ColorRGBA[length];
Vector3f center = new Vector3f();
/**
* only use boxes which are of a specific author
*/
System.out.println("Checking for: " + author);
for (int i = 0; i < boxes.size(); i++) {
if (authors.elementAt(i).equals(author) == true) {
boxes2draw.add(boxes.elementAt(i));
}
}
for (int j = 0; j < boxes2draw.size(); j++) {
center = boxes2draw.elementAt(j).getCenter();
vertex[j] = new Vector3f(center.x, center.y + boxes2draw.elementAt(j).yExtent, center.z);
System.out.println(vertex[j]);
color[j] = ColorRGBA.white;
}
Line connectingLine = new Line("Connecting Line", vertex, null, color, null);
connectingLine.setMode(Line.LOOP);
connectingLine.setLineWidth(LINE_WIDTH);
connectingLine.setDefaultColor(ColorRGBA.white);
lineNode.attachChild(connectingLine);
lineNode.setRenderState(ms);
lineNode.updateRenderState();
nodes.add(lineNode);
}
event if the point (0,0,0) is not in the vertex list ( i checked it throug the system.out.println), the line always goes trhough the origin (0,0,0). does anybody know, how i can prevent that?
i tried to set the connecting mode to connected or loop but it doesn't matter.
thx 4 u help!
