geom.node.start.edge
Syntax
- e = geom.node.start.edge(n)
Get the first edge connected to a node. This can be used to iterate through all edges attached to a node with the
geom.node.start.index
,geom.edge.next.edge
andgeom.edge.next.index
functions.Returns: e - edge pointer Arguments: n - node pointer
Usage Example
The following example illustrates how geom.node.start.edge
can be used to iterate through all edges attached to a node, counting the number of edges.
global test21 = geom.edge.node.pos(pnt,2)
global test22 = geom.edge.pos(pnt)
; Test node to edge loop
global test23 = 0
local node_pnt = geom.node.find(setpnt,1)
local edge_pnt = geom.node.start.edge(node_pnt)
local node_ind = geom.node.start.index(node_pnt)
io.out(edge_pnt)
io.out(node_ind)
loop while edge_pnt # null
