I understood!
I will try to make a patch to help you with this. It seems a thing that I will also need for my project!
About the overlapping, what my plugin does is give an extra value for the z index. By default, RPG Maker decides that index with the character priority. So just for example:
- Below Characters → Index = 0
- Same as Characters → Index = 1
- Above Characters → Index = 2
My plugin adds an extra z index value, that by default, is 0. So you can change that to increase or decrease a character index:
- Below Characters → Index + extraZindex
- Same as Characters → Index + extraZindex
- Above Characters → Index + extraZindex
If you have an event set as Same as Characters, with the extra z index as -2, the real index will be -1. So they will appear below a character that has the priority Below Characters.
Is that your doubt?
