Mouse Tweaks replaces the standard RMB dragging mechanic, adds two new LMB dragging mechanics and an ability to quickly move items with the scroll wheel.
Very similar to the standard RMB dragging mechanic, with one difference: if you drag over a slot multiple times, an item will be put there multiple times. Replaces the standard mechanic if enabled.
Hold your right mouse button:
Drag your mouse around the crafting grid:
You can drag your mouse on top of existing items:
LMB Tweak (with item)
Lets you quickly pick up or move items of the same type.
Hold your left mouse button to pick up an item:
Drag your mouse across the inventory. Items of the same type will be picked up:
Hold shift and drag. Items of the same type will get “shift-clicked”:
LMB Tweak (without item)
Quickly move items into another inventory.
Hold shift, then hold your left mouse button:
Drag your mouse across the inventory. Items will get “shift-clicked”:
Scroll to quickly move items between inventories. When you scroll down on an item stack, its items will be moved one by one. When you scroll up, items will be moved into it from another inventory.
Configuration setting: WheelTweak=1
Configuration setting: WheelSearchOrder=1
When you scroll up, the mod will search for items from last to first (when this is set to 1) or from first to last (when this is set to 0).
Configuration setting: WheelScrollDirection=0
Set this to 1 to invert the default scroll actions. So, when set to 1, scrolling down will pull the items and scrolling up will push the items.
Set this to 2 to enable the inventory position aware scrolling. Scrolling up will push the items into the other inventory if it’s above the selected slot, or pull items from the other inventory if it’s below the selected slot. Vice versa for scrolling down.
Configuration setting: OnTickMethodOrder=Forge, LiteLoader
Mouse Tweaks can use multiple APIs for an OnTick method that it requires. You can use this setting to control the API it prefers. This shouldn’t really matter at all. If a method isn’t supported (for example, you don’t have the API installed) the mod will proceed to check the next ones.
Configuration setting: ScrollHandling=0
Toggles between “smooth scrolling, minor issues” (0) and “non-smooth scrolling, no issues” (1). When set to smooth scrolling, minor issues may be experienced such as scrolling “through” JEI or other mods. When set to non-smooth scrolling, those issues will not happen, but the scrolling will be a little non-smooth. Non-smooth scrolling works only with the Forge OnTick method.
This option is set to smooth scrolling by default because the aforementioned issues require rather specific conditions to trigger and aren’t very impactful, while scrolling items is something you do all the time and want the experience to be as good as possible.
