Easily add trims to your armor, using a simple GUI.

This script requires Skript (obviously), SkBee, and skript-gui.

To add an armor trim to armor:

• Hold the item and do /trim. A GUI will be displayed with all the available trim patterns. Once you pick one of these, you'll be prompted for which material you want to use.
• If the shouldUseResources option is enabled, you'll have to have the relevent smithing template, as well as the material, in your inventory for the armor trim to be applied. If disabled, the trim will apply no matter what.

It should be noted that if the armor trim you're trying to apply to your armor is already applied, you will receive an error message if the shouldUseResources option is enabled, so as not to consume resources superfluously.

Unfortunately, Minecraft only uses 1 item texture for all different trim patterns. So despite what it may look like in the GUI, each slot is a unique pattern. You'll only be able to see the pattern when you wear the armor!
