A representation of a bot's relative movement that can be used in recording and reconstructing firing angles. The bot's positions at the beginning and end of a period of time (e.g., as produced by a [[waves|wave]]) form a vector relative to the bot's initial heading. The resulting vector can be applied to future situations to project the enemy's movement and deduce a firing angle. The vector may be scaled by [[Bullet Travel Time]] to adapt it to different distances and bullet powers, similar to how [[GuessFactor|GuessFactors]] are scaled by [[Maximum Escape Angle]].

== Advantages ==

* The data recorded is not relative to the location of the firing bot, as a [[GuessFactor]] would be. This is important in [[melee]], where most enemy movements are not relative to a specific opponent.
* When predicting enemy movement, projections that lead out of bounds can be ignored or adjusted.
* Reconstructing firing angles is much faster than [[Play-It-Forward]] simulation, while offering similar advantages.

== See also ==

* [[Diamond]] uses displacement vectors in its gun.
