Hi, I'm trying to draw a line by using ImmediateGeometry. I found that if I draw the line after queue_free() the previous ImmediateGeometry node and regenerate a new one. The positions that the previous line had is still counted in. I'm sure I put the clear() function before beginning to draw. How to clear previous data when drawing a new line?

var spam = null

var ball: Spatial = null
var geo: ImmediateGeometry

ball = get_node(ball_node)
create_geo()
func draw_mesh(geob: ImmediateGeometry, vextex_pos: PoolVector3Array):
geob.clear()
geob.begin(Mesh.PRIMITIVE_LINE_STRIP)
for i in vextex_pos:
geob.add_vertex(i)
geob.end()
func create_geo():
geo = ImmediateGeometry.new()
add_child(geo)
