panda3d.core.LineSegs

Scripting Issues

Hello,I’m trying to use LineSegs and can’t understand how to remove lines.

     lines = LineSegs()
     lines.moveTo(0,0,0)
     lines.drawTo(0,2,0)
     lines.setThickness(4)
     Node = lines.create()
     Np = NodePath(Node)
     Np.reparentTo(render)

Then I’m trying to do this:

     Np.removeNode()
     lines.reset()

In fact, the API has no idea about deleting rows. If you want to delete rows, you need to present them as separate nodes.

from direct.showbase.ShowBase import ShowBase
from panda3d.core import LineSegs, NodePath


class MyApp(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        
        lines = LineSegs()
        lines.moveTo(0,0,0)
        lines.drawTo(0,2,0)
        lines.setThickness(4)
        
        lines1 = LineSegs()
        lines1.moveTo(0,0,0)
        lines1.drawTo(0,0,2)
        lines1.setThickness(4)

        Node = lines.create()
        Node1 = lines1.create()
        
        Np = NodePath(Node)
        Np.reparentTo(render)

        Np1 = NodePath(Node1)
        Np1.reparentTo(render)
         
        #Np1.removeNode()

app = MyApp()
app.run()
