I found this script

And I run into a problem every time I try to call the script that I need to add an Esper into the player's Esper inventory. NOTE: I try this when I try to enter one esper at a time.

The problem reads "Argument Error occurred while running script. wrong number of arguments (0 for 1)"

I looked all over forums and even read the one I provided. Although I can't seem to find whats wrong. I tried fixing the script but I know vary little about ruby so I need some help. Thanks!

How are you calling the script.

I call the script using "$game_party.gain_esper (ESPER::CACTUAR)" using the Esper Cactuar, but for some reason it cannot call just one.

Make sure your script is not something like



Only the periods can be separated on different lines, so



would be a valid call that passes one argument, whereas the first one passed none.

But ya, I would change the gain_esper function to accept a number that represents a particular esper in an array (ie: 1 is Cactuar, 2 is Bomb, etc).
I would probably even try to look for a way to make it so you just have to write "gain_esper(...)" rather than having to write "$game_party.gain_esper"

Though I'm not sure which looks better. Given the script box constraints, I would naturally go for the simplest function calls.

So I tried what you did here

And it now gives me this...
"Name Error occurred while running script. Uninitialized constant Interpreter::ESPER"
I don't actually know what the problem is here, but thanks for the help!

Oh, it's ESPERS with the s at the end.

Dude! Thank you so much that solved the problem. THANK YOU!
