Replace Item Function Definition AFRLme

This script allows you to replace one item with another while keeping the items position in the inventory. This script is especially useful for when you are replacing a manipulated item such as an empty bucket that has just been filled with water. By default Visionaire Studio would add the new item to the end of the inventory.

Instructions

1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2. To use this function you have to include both the names of the item you want to replace, & the item that that you will be replacing it with; item names are case & character sensitive.

replaceItem("empty_bucket", "bucket_of_water")
