layer number ?

Coding Python Support

how do you specified to move an object to a specific layer

do you have to specify all the layers like

[FONT=ArialMT][SIZE=2]layer=[True]+[False]*31

or is there another shorter way to say like moe it to layer 2?

Thanks
[/SIZE][/FONT]

wouldnt it be easy to just write a small function ? something like:


def layer_move(obj, target):
    [layer = False for layer in obj.layers]  #remove object from all layers
    obj.layers[target] = True #set the layer
3

i think i found it but not tested yet

layers = 32*[False]
layers[0] = True

so just change layer number and uit should be come true i guess

sorry did not mention i’m using a primitive plane and cube

there must be an easier way to spec the layer where we want it to be
instead of all the layers except one!

but could also be applied to object in general

but there is a bpy.ops command to move and object to first or may be the active layer in viewport layer

bpy.ops.object.add_named( linked=False, name=“lamptypic1”

Thanks

thats not working either because the object has to be on at least one layer.
it should be:


bpy.context.object = (i-1)*[False]+[True]+(20-i)*[False]
5

The last UV is added on first layer = 1

so the method is working

but your might also be another way to spec it

There is also a specific object command to change layer and even one to move to another layer
but not really used theses before !

THanks and happy 2.5
