Is delay allowed?

[Wubsie]

Your step 2 is exactly like mine. It does a delay after real event. Why do you think that yours is better?

Also, splitting key event into down and up looks to be self-deception. I cannot find a bluepost now but I am pretty sure that Blizzard doesn't agree with this split. One key press is one event, with both down and up. You are not banned just because, as Lax said, multiply sendings are allowed if done at same time.

The difference seems to me to be that the action is triggered without delay due to the input by the player. It does not execute the action automatically after the delay but rather stops the player from taking that action for a set time. Think of it like unbinding or disabling a key outside of the game for a set amount of time.
