add allowHomonymObjectName option for OBJModel.ModelSettings #9047
base: 1.19.x
Are you sure you want to change the base?
Conversation
rename only works on the `o` .obj command/keyword now when allowHomonymObjectName is true and rename happens just plus char '_' and a unique number id, so you can just get all homonym parts by call filter and use methods like startWith with the homonym part as parameter

This is a breaking change because any callers to the previous constructor (without the new parameter) will break.
Please add a new constructor to this record which calls the canonical constructor with an appropriate default value for the new parameter, mark that new constructor as deprecated for removal (@Deprecated(forRemoval = true, since = "1.19.2")
, and add a javadoc with a @deprecated
tag directing users to the canonical constructor (which has the new parameter).

Some error message cleanup, as well as using logger parameter substitution instead of manual string concatenation:

I wonder if we should begin this at 1 instead, so the names would be: object
, object_1
, object_2
.

This PR adds the ability for the OBJ Loder to load .obj file with the same part name
this PR follows #8624, but for Minecraft version 1.19.2 and a small difference.
I don't know how to change an existing GitHub PR's source/target branch, so I just open a new one
Why need this?
for modeling software such as BlockBench which allows homonym cube names. When its model is exported as a .obj model file. The name subsequent to the .obj format command/keyword
o
will duplicateDue to the current OBJ Loader implementation, the collection of the parts is a
Map<String, ModelGroup> parts
, so the latter will override the former. As a result, only the last part will remainImplementation
add an option bool for
OBJModel.Setting
calledallowHomonymObjectName
which is false by default.when reading from json file, its key is
allow_homonym_object_name
we now will check whether the same part name occurs before, if it is and the option is true, we re-name it by plusing a char
_
and a non-negative growth number after the original name until no-repeat occurs.In a similar way to another modeling software called Blender, it can correctly load .obj file with homonym object names
re-name only works on the
o
.obj command/keyword nowAddition
When finding any part name that occurs before, we use a bool to record this. When load end we print an error message that indicates this and prompts this option when the option is false as this is usually not expected behavior.
