Python: create bezier curve

[cmcpasserby]

im trying to create a 2 point bezier curve from the cmds commands in python bit hit a little snag.
i first got hte command by placeing a curve and looking at the script editor histry whihc showed me hte mel command

curve -d 3 -p -144 0 0 -p -144 0 0 -p 64 0 0 -p 64 0 0 -k 0 -k 0 -k 0 -k 1 -k 1 -k 1 ;

than made that into it's python equlivnet.

import maya.cmds as cmds
cmds.curve( d=3, p=[(-144, 0, 0), (-144, 0, 0), (64, 0, 0), (64, 0, 0)], k=(0, 0, 0, 1, 1, 1) )

but once i run that python code it creats just a basic curve.

does anyone know why this is happening?

Definitely some wonkyness with the bezier curves, probably by design -- they're a subset of the NURBS system in Maya.

Try this:

import maya.cmds as cmds
cmds.curve( d=3, p=[(-144, 0, 0), (-134, 0, 0), (54, 0, 0), (64, 0, 0)], k=(0, 0, 0, 1, 1, 1) )
cmds.nurbsCurveToBezier( )

Your tangent handles were stacked, I moved them off 10 units and converted the curve to bezier. Works on my end.

Apologies for not posting in a code box, didn't work with my browser.

thanks mate, exactly what i was looking for.

kinda odd it dosnt show that step the the scrip editor output when youy call the command from the UI.

also your a polycounter right? name and avatar look familiar.

Glad that helps. I haven't dug into bezier in Maya but I suspect they're just standard NURBS curves with some special visual controls.

I am on polycount from time to time. Great game dev forum!

ya was wanting one since the bezier olny requires 2 control points, and the script im building builds the curve between 2 objects, so was useing it for simplicity.
