Poly Letter Kerning

Hello,
I'm trying to write a script for to align letters according to their bounding box xsize.
(Like in arrange command but depending on previous objects xsize)
For example each polygonal letters A,B,C have different xsizes. I want something like polygonal kerning:)
Problem:

How it should look like (more or less) :
https://www.dropbox.com/s/pdjt4cp3f2t5vl5/alphabet1.jpg?dl=0

And my testing scene :
https://www.dropbox.com/s/lb34jrvh30q8691/scene_for_testing_script.c4d?dl=0

My code is :
(Note: All objects are centered to object axis, zero PSR and they are under a null as shown in the image above.)
I tried to assign objects into an array. But I stock around positioning them.
Please show me an example or check my script and note that I'm a beginner.
(P.S. I should solve that issue with Python Script because it will be another part of my main script...)
Thanks a lot.

import c4d
from c4d import Vector

def find_objects(op, objectarray) :
      
    objectarray.append(op)
    for child in op.GetChildren() :
        find_objects(child, objectarray)
 
def getsize(op,size) :
    
    size = op.GetRad()*2
    position = op.GetMp() + op.GetAbsPos()
    xsize = int(size.x)
    xsizearray.append((xsize))

def main() :
    
    global xsizearray
    
    objects = []
    size = []
    xsizearray = []
    position = []
    xpos = []
    for obj in doc.GetObjects() :
        find_objects(obj, objects)
    
    count = len(objects)
    
    for i in xrange (count) :
        getsize(objects _,size)
        
        print xsizearray _
        objects _.SetRelPos(c4d.Vector(xsizearray _,0,0))
        c4d.EventAdd()
    
main()

Hello,

I guess you would have to check if two letters collide and move them around until they don't collide anymore. In C++ there is the GeColliderEngine available that might be used. Currently this engine is not avialable in Python, so you have to develop an own solution.

Best wishes,

Hello,
Thank you for an answer,
What I need is something basic actually, those letters are polygons I'm calling them from specific library and merge them into a scene. Basically following letters should be located next to previous letter depending on its bounding box xsize.

I tried something, but it's moving all letters ( Sorry I'm a beginner:) )
Any advice please?

import c4d

def find_objects(op, objectarray) :
      
    objectarray.append(op)
    for child in op.GetChildren() :
        find_objects(child, objectarray)
 
def getsize(op,size) :
    global xsize
    size = op.GetRad()*2
    position = op.GetMp() + op.GetAbsPos()
    xsize = int(size.x*2)
    xsizearray.append((xsize))
    
def move(op,sizex) : 
    pos = c4d.Vector(sizex,0, 0)
    op.SetRelPos(pos)
    
    
def main() :
    
    global xsizearray 
    objects = []
    size = []
    xsizearray = []
    for obj in doc.GetObjects() :
        find_objects(obj, objects)
    
    count = len(objects)
    
    for i in xrange (count) :
        getsize(objects _,size)
        move(objects _,xsizearray _)
    print ("Count of Objects " + str(count) )
    print ("Objects' X Size Valuess " + str(xsizearray) )
    
    c4d.EventAdd()
    
main()

Hello,

it seems that when you call "getsize" and "move" you hand over all objects and not a single object.

I got you a working example at c4dcafe, as a reply to your post there, grasycho.
