AdrX003 I am afraid the information present in this thread is quite out of date due to the simple fact it has been nearly a year since OP created this topic.
Since this mods release it is now possible to use the GSC function replacefunc() in order to replace any GSC function, save a few, with your own function. Therefore, you can make use of the custom named script functionality also present to never need to override a stock script wholesale.
I am locking this topic due to two reasons:
A. The way this mod achieves the objective is obsolete.
B. OP has not participated in any discussions in this topic in nearly a year.
I will recreate the same functionality using the new scripting technology and of course give OP credit and link his original topic.
Furthermore, I will try to dedicate some time this weekend to creating a proper guide on the proper utilization of the new scripting features for T6.
If you have any further questions I recommend contacting me via Discord: JezuzLizard#7864 I will take notes of any discussions for my upcoming guide on what new and skilled modders most want to know.
If you cannot contact me via Discord please create a new topic in the modding discussion sub forum and tag me.
