After some further testing. It seems like a lot of the MV code was changed, so my configurations do not carry over.
Things like damage need to be implemented (like how it was in the MV demo):
"this.character(0)&&this.EID>0
this.character(0).hp-=this.BP[1];"
does not work in MZ. Probably because there doesn't seem to be an "action" command any more. example: "Action:["C[1,10]"],"
For now I will continue to use MV until the MZ demo is as feature complete as the MV version.
