python for loop with a mel function included

[mia...@hotmail.de]

hello
i want to do a planar mapping of four objects like this:

import maya.mel as mm
for i in range(12,15):
mm.eval("polyProjection -ch 1 -type Planar -ibd on -kir -md z pCube%s.f[4:6] pCube%s.f[8];" % i)

sadly this wont go...does anyone know how to do this ? I would be very thankful:)

I'm pretty sure the error you are seeing from this is that there are not enough format arguments for the string? It is because in your string you use %s two times but only provide one format argument. It would work if you modified it to:

mm.eval("polyProjection -ch 1 -type Planar -ibd on -kir  -md z  pCube%s.f[4:6] pCube%s.f[8];" % (i,i))

​

Also, you said you wanted to affect 4 objects, but if you do range(1,4), that will only produce [1,2,3]

I think you could also express this through the python commands module with:

import maya.cmds as cmds 

for i in xrange(1,5):
    obj = "pCube%d" % i
    objs = ["%s.f[4:6]" % obj, "%s.f[8]" % obj]
    cmds.polyProjection(objs, ch=True, type="Planar", ibd=True, kir=True, md="z")
