Custom Item-Dragging System

Name	Type	By
Custom Item-Dragging System	Definition	Christopher A. Summer

This script is an alternative for the default item-dragging in Visionaire Studio. It allows the item cursor to react to object hotspots in various ways.

Instructions

1. Add the main script to the Visionaire Studio Script editor & set the script as a definition script.
2. Disable the default item-dragging by unchecking Allow dragging of items from inventory in the game properties and/or unchecking Items can be dragged with this command for all command buttons.
3. Choose "Combined command" as the command type for the command button you wish to drag items with.
4. In your actions for combining an item with an object/character/item do not use the execution type "Item dropped" but instead choose "Executed command" and select the item (combined command).

Main Script

-- SET GENERAL SCALE AND SCALE-WOBBLE WHEN ACTIVE:
local ItemScale
local ItemScaleGeneral   = 0.75
local ItemScaleFactor    = 0.025  -- 0.0 to deactivate scale-wobble
local ItemScaleSpeed     = 0.0125 -- 0.0 to deactivate scale-wobble
-- SET ROTATION-WOBBLE WHEN ACTIVE:
local ItemRot
local ItemRotationFactor = 0.2    -- 0.0 to deactivate rotation-wobble
local ItemRotationSpeed  = 0.5    -- 0.0 to deactivate rotation-wobble
-- SET ALPHA WHEN INACTIVE AND ACTIVE:

-- SET COLOR WHEN INACTIVE AND ACTIVE:
