Blender Script - How would you copy all modifier settings like Collisions from an active object to other selected objects?

Question

So the issue im trying to solve is how would you copy all modifier settings or attributes (like Collisions) from an active object to other selected objects? I have many objects I need to copy settings across all of them.

I have already tried "Copy from Active", but that just copies ridge body settings. I tried to use the "Copy Attributes", but that just copies the modifier and not the settings. Is there a way to write a script that will do that? The ultimate way would be to link it to a button in the UI.

I have little knowledge of python. I was able to write a script to make a button make a simple operator..so I get the basic idea, but i don't know how to write an operator to do what i would like.

Any answers would be appreciated.

Copy collision settings

use dir(x) to get list of attribute

import bpy

def try_set_attr(ob_from, ob_to, attr):
    try:
        setattr(ob_to, attr, getattr(ob_from, attr))
    except:
        pass

def copy_collision():
    active_obj      = bpy.context.object
    selected_objs   = bpy.context.selected_objects

    for md_act in active_obj.modifiers:
        if md_act.type == 'COLLISION':
            for obj in selected_objs:
                if obj == active_obj:   continue
                if obj.type != "MESH":  continue
                coll_md = None
                for md in obj.modifiers:
                    if md.type == 'COLLISION':
                        coll_md = md
                        break
                
                if coll_md is None:
                    coll_md = obj.modifiers.new(type='COLLISION', name='Collision')

                for attr in dir(coll_md):
                    try_set_attr(md_act, coll_md, attr)

                setting_from    = md_act.settings
                setting_to      = coll_md.settings
                
                for attr in dir(setting_to):
                    try_set_attr(setting_from, setting_to, attr)
            break

copy_collision()
