Prototick

A prototick is a one-tick delay in attracting an orb that arises in certain situations. When a prototick occurs, the player faces the orb but does not attract it. There are two distinct types of prototick: tap-prototick and movement-prototick. The distinction between these two types of prototick is slightly technical but proves to be decisively important in advanced techniques such as pseudorepel.

Tap-prototick
The tap-prototick occurs after an orb is tapped and the player clicks again on an orb immediately the tick after, whether it be the same orb or a different one.

Movement-prototick
The movement-prototick occurs when the player clicks on a orb immediately after having moved, without premovement.

Distinction between the two prototicks
In tap-prototick, the player can cancel the attraction of the prototicked orb. However, in movement-prototick, the player cannot cancel the action. In fact, what happens in movement-prototick is that the game forces the attraction to occur no matter what the circumstances are in the next tick, even if the orb becomes out of reach. This forcing gives birth to a class of advanced techniques called forced attract, with pseudorepel being one of them.
