This new block would allow redstone-users to decide when something is activated if unwanted power goes into it. For example, if an observer sends out a redstone signal when it detects a detector rail activating, and sends another one when it detects it deactivating, but you only want it to send out a signal when it deactivates, you use an absorber. Here's how it works:
When you right-click it, you decide how many times it wants to absorb a signal. By default it is 2 and can reach a maximum of 15. Let's say our absorber is on the default setting. When it recieves a redstone input, rather than transmitting said input, it will absorb that input. If it's set to 2 absorptions, when it recieves a second redstone input, it will then transmit the signal.
Now let's say it's set to six. If it recieves a redstone input, it will absorb it and do nothing else. If it recieves another input, it will still absorb it and nothing else. Only when it has recieved six individual inputs will it finally send a redstone output.
How could it be used? Well, say you want a dispenser to dispense water when a wheat crop reaches its oldest stage. Since wheat has 7 stages, an observer will detect every single stage, dispensing water each time. But, if we use an absorber, it can absorb each redstone input until the 7th one. By this time, we know the wheat has reached its maximum growth stage and the absorber releases an output, dispensing water on the wheat.
