Main costume npc

[is94ns13]

If you guys can help me out that be perfect!

I got lots of costume npcs, is there a way to make simple script that will generate special points per every zeny spend on costume npcs. And i wanna be able to see how much points i saved up and have option to trade those points for items like apple = 10 points

For example

I want it to generate 1% of total zeny spend

1000zeny = 10 points

1000*1%=10

Then option to see how much points i saved up

Then option to trade points for items

I hope my discriptionon was good enogh
