Information in exchange for money

[pedro ique]

Need to create an event that npc covers a value to give an information. How can you do this?
Example: a npc says that if it receives 200,000 it will say where a legendary pokemon or an item is found.

Use the "change gold" event command. Don't forget to use the "show choices" if you don't want the player to be robbed.

Also, this is basic RMXP. Use AND abuse more of event commands. You can make pretty much everything with just that.

Don't forget that you'll have to check for the player's money as well, so you can make sure it doesn't go negative (if even possible), but more importantly that he says something different when you don't have enough money.

Can you put pictures of how to do this event?
