How to use convert time_info into python to add animation? about animation_nodes HOT 6 CLOSED

The Time Info node just returns the value of self.nodeTree.scene.frame_current_final, so you can use that. Or are you talking about something different?

nodeTree.scene.frame_current_final

Hi Omar:
According to your previous posts, I changed cython coding to generate below:
myfalloff = my_wiggle_falloff.WiggleFalloffNode.execute(my_wiggle_falloff.WiggleFalloffNode, 0, 100.0, 1.0, 0.5, 0.5, 2, 0.3)
myoffset = (0, 0, 1)
myoffsetvectornodecls = my_offset_vector.OffsetVectorNode()
myvectors = myoffsetvectornodecls.execute_List(vertexLocations, myfalloff, myoffset)

I just have no idea how to link self.nodeTree.scene.frame_current_final with evolution in myfalloff.
I tried to add animation but failed:
for i in range(50):
context.scene.frame_set(i)
frame = scene.frame_current_final
outmesh = bpy.data.meshes.new(name="Target")
myobj = bpy.data.objects.new("Target", outmesh)
bpy.context.collection.objects.link(myobj)
..get meshData and setMesh(outmesh, meshData, myobj)
And then in the loop, I generated 50 Target objects, but no animation.

Thank you for the help!

evolution is the third argument to the WiggleFalloffNode.execute function, so passing the frame number instead of 100 in your example should be what you need. Though this seems rather hacky, that is, to execute the nodes manually, so not sure if it is worth doing it that way.

context.scene.frame_set(i)
frame = scene.frame_current_final

Thanks Omar for the reply. No real use indeed just for testing Cython.

for i in range(50):
        scene.frame_set(i)
        frame = scene.frame_current_final
        myfalloff = my_wiggle_falloff.WiggleFalloffNode.execute(my_wiggle_falloff.WiggleFalloffNode, 0, i, 1.0, 0.5, 0.5, 2, 0.3)
        myoffset = (0, 0, 1)
        myoffsetvectornodecls = my_offset_vector.OffsetVectorNode()
        myvectors = myoffsetvectornodecls.execute_List(vertexLocations, myfalloff, myoffset)
        
        try:
            meshData = Mesh(myvectors, edgeIndices, polygonIndices, skipValidation = skipValidation)
            if len(materialIndices) == len(polygonIndices) and materialIndices.getMinValue() >= 0:
                meshData.insertBuiltInAttribute(Attribute("Material Indices", AttributeType.MATERIAL_INDEX, AttributeDomain.FACE, AttributeDataType.INT, materialIndices))
            else:
                print("Invalid material indices.")
            
        except Exception as e:
            print(str(e))
        
        print(meshData)
        outmesh = bpy.data.meshes.new(name="Target")
        myobj = bpy.data.objects.new("Target", outmesh)
        bpy.context.collection.objects.link(myobj)
       
        meshDataType = "MESH_DATA"
        if meshDataType == "MESH_DATA":
            setMesh(outmesh, meshData, myobj)
        elif meshDataType == "BMESH":
            setBMesh(outmesh, bm)
        elif meshDataType == "VERTICES":
            setVertices(outmesh, meshData.vertices)

But I failed to generate animation but got 50 Target Objects instead.
In mesh_object_output.py.py, I noticed that animation is built by below, but no idea how to proceed?

if not isAnimated(mesh):
mesh['an_helper_property'] = 0
mesh.keyframe_insert(data_path = '["an_helper_property"]')

To clarify, do you actually want an animated mesh? In that case, this will not work, and the creation of multiple meshes is expected. Animation Nodes is able to animate meshes because it executes on frame changes and adjusts the mesh directly instead of creating a new one.

Got it! Thanks!
