[Solved] Help with "Select Key Item" script call

CheerfulGoth · 2018-09-13T05:15:34+0900

Hello! I am fighting with a small, maddening issue. I am using the "Select Key Item" script call ($gameMessage.setItemChoice(var, n)) in a common event. And it works well! My issue: the event runs the second script before I have selected an item in my window, and therefore throws me a "hey, this is undefined" error. I can't figure out how to make RPG Maker wait before running the rest of my code. I believe this is happening because when you use the command instead of the script call, Game_Interpreter sets a wait mode, while my code doesn't: I can't, however, find a function to manually set the wait mode myself. Any advice? Even hackey solutions are welcome. I just want this to work. Do you really need to use the script call instead of an event command? Yes! I made a custom category that shows me only certain items based on a variable. Can't really do this in any other way :V Attachments upload_2018-9-12_22-5-12.png 31 KB · Views: 14

Yes!

You've pretty much answered your own question - When you execute code from the Script Event Command, the value of "this" is actually the instance of the Game_Interpreter that is interpreting the event commands. So in the same script command as $gameMessage.setItemChoice you can execute:
Code:
this.setWaitMode('message');

Oh! I am still a n00b scripter and had no idea about this.
Works beautifully, thanks a lot!
