Thank you for your help...
my Implementation is as follow.
I used Polygon with numpy support to test if moving Polygons and
BoundingBox Polygons overlaps.
My question is:
I get an event on every mouse over of an polygon but i like to have
an event only if mousedown or realy objekt moving.
1. How can i get an event if real objects are moving ?
(onDrag on Drop)
Another question is:
2.How can i Flip y axis in floatcanvas2 like ProjectionFun in FC1?

-----Code--------------
import Polygon
class MoveNodeWithCollisionDetection(fc.guiMode.GUIModeMoveObjects):
def __init__(self, nonSelectableNodes = []):
self.nonSelectableNodes = nonSelectableNodes
self.look1=fc.SolidColourLook( line_colour = 'green',
fill_colour = 'red' )
self.look2=fc.SolidColourLook( line_colour = 'red', fill_colour
= 'green' )
def on_move(self, event):
''' filters all static objects and moves the non-static ones '''
if event.node.model ==None:
return
movepoly=None
try:
#print type(event.node.model.points),
points= event.node.model.points
matrix=event.node.worldTransform.matrix
trpoints=numpy.dot( numpy.column_stack( (points,
numpy.ones(len(points))) ), numpy.transpose( matrix ) )[ ..., :-1 ]
#print "matrix:\n",matrix
#print "Transformed points:\n",trpoints
movepoly=Polygon.Polygon(trpoints)
#print movepoly.center()
except Exception, e:
pass
#print e
query = fc.nodes.spatialQuery.QueryWithPrimitive( primitive =
event.node.boundingBox,exact = False )
#for elem in query.primitive:
# elem.look=self.look2
intersectingNodes = self.canvas.performSpatialQuery( query,
order = False )
print "count bounding objects:",len(intersectingNodes)
if movepoly:
for elem in intersectingNodes:
try:
points= elem.model.points
matrix= elem.worldTransform.matrix
trpoints=numpy.dot( numpy.column_stack( (points,
numpy.ones(len(points))) ), numpy.transpose( matrix ) )[ ..., :-1 ]
testpoly=Polygon.Polygon(trpoints)
if testpoly.overlaps(movepoly):
elem.look=self.look1
print "collision" #stop moving
else:
fc.guiMode.GUIModeMoveObjects.on_move( self,
event ) # move if nothing overlaps
elem.look=self.look2
except Exception, e:
pass
#print e
print elem
