hi there...
is there really no method to search for an object by name returning a list?
there could be multiple objects with the same name!do you have to traverse the complete tree for that???

Yes, just iterate over your objects and check for whatever you like to.
Non recursive hierarchy iteration is blazingly fast, so don't worry about performance. -

cant do that
if i want to search an object name in complex scene,
it is too slow to walk the complete hierarchyif you have to do this all the time it hogs the app
there really could be better methods to select objects!

Well, I don't see any scenario where this would be neccessary though.
May I ask what you try to achieve? -

In general mp5gosu is right, the only thing we have is SearchObject(), which can only return one object unfortunately.
I'd also like to second mp5gosu's question, so we could maybe add ideas.
If we added a new function, which search criteria should be covered besides names? Types? Existence of certain parameter types or names? Animated parameters? Existence of certain tags? Links to other entities?
Don't get me wrong. I don't want to turn down your request. If there's a need and some benefit, we will certainly consider the extension of the API. -

About SearchObject to making it more user friendly we can think about adding a function SearchObjects(who gonna return a list of object)
Then we can also imagine bunch of options:
- SearchObjectByType: Check if op match this type
- SearchObjectByTag: Check if op get this tag type
- SearchObjectByParameter: Check if op get a certain parameter ? Maybe add addition input for also checking value
- SearchObjectByParent :Check if op is a child of parent
- SearchObjectByCustom: Accept a lambda function wich return a bool if op must be selectect or not.
Then we can think about why maxon should take time for doing this kind of stuff that user can easily down with a correct understanding of the actual SDK?
- Firstly for new comer. I'ts way more user friendly to simply call SearchObjectByNames and get a list of a object than to build your own list with the need to make a recursive function
- Optimization, I get no proof about that, but I'm pretty sure most of developers actually doing stupid basic recursive search, while there are more complexes algorithms to optimize it like using multi-threading for exemple.

Well, I agree with gr4ph0s, in particular on that custom function that accepts lambdas (or even functors, if someone wants that pain)
But for "everyday"-use, a filtered list would come in handy.

I totally agree with you.
I didn't thinked about filter (I'm not a big boss about functional programming, but need to improve it !).
But should be really come handy even for other task than iterate, combined with the idea I came yesterday it come a very powerful toolset.We would able to write something like this
#Constant define inside c4d #FILTER_EGUAL_TO_VALUE = 0 #FILTER_GREATER_THAN_VALUE = 1 tags = SearchObjectsByTag(c4d.Tphong) tag_to_change_first_step = FilterByParameter(tags, c4d.PHONGTAG_PHONG_ANGLELIMIT, c4d.FILTER_EGUAL_TO_VALUE , True) tag_to_change_second_step = FilterByParameter(tag_to_change_first_step, c4d.PHONGTAG_PHONG_ANGLE, c4d.FILTER_GREATER_THAN_VALUE, 0) -

i think SearchObject() just disrespects the fact that there could be multiple objects with the same name.
so SearchObject s () returning a list would be a good idea.additional filter methods etc would nice but its kinda endless and can be done by python anyway

Thanks for all your input. Much appreciated!
I'll take the ideas and forward them to development.
