If you're holding the block with your cursor, right clicking on an empty spot will place one single unit. If the block is in an inventory slot, right clicking on it will make you pick up half of it.
right click the stack and add it will give you half if you want to split it more then right click it more the once.
If you mean split the stack in half i think it is right click? last time i checked it was.
No, THINK OF it THIS WAY you can't stack shields to 64 in real life so you can't in Minecraft ETHIER.
To take all items from a stack at once, you hover over the item and hold shift and left click at the same time, this will move the entire stack in one movement.
A standard stack in Minecraft is 64. However, certain items, including ender pearls and snowballs can only be stacked to 16.
Right clicking on a stack of any block or item with no block or item in your hand will split that stack in half with the stack in your hand having extra if the original stack had an uneven number of items. Right clicking with a stack will place one of the items in the inventory slot highlighted at the time.
Click on the stack to pick the whole stack up, then right click on an empty inventory slot to deposit a single unit of the stack.
You need to take the stack and right click, which will only take one block from the stack to where you are pointing at.
You can't. Currently, beds are unstackable.
To get a full stack you would hold shift and then click the arrows.
Nothing...
If the stack is empty assume the stack pointer has a value of P. when you push something on the stack you increment P. when you pull something from stack you decrement P.
