This works perfectly! Thank you!
I'll go ahead and buy this full plugin since that's exactly what I need~
I did figure out a simple way to code it which I'll put below in case anyone ends up just needing this specific thing, easier than I thought. I prefer your way better :)
Game_BattlerBase.prototype.maxtp = 100;
Game_BattlerBase.prototype.maxTp = function(){
return this.maxtp;
}
and from there just change maxtp with script as needed, no need to make any other changes to maxTp function.
