-'''Mirror Movement''' is a form of [[One on One|1v1]] movement that tries to copy the movement of the enemy.  Though it can be effective against opponents with strong movement, it is utterly useless against opponents with weak movement or [[oldwiki:AntiMirrorGun|antimirror targeting]].
+'''Mirror Movement''' is a form of [[1v1]] movement that tries to imitate the movement of the enemy. Though it can be effective against opponents with strong movement, it is utterly useless against opponents with weak movement or [[oldwiki:AntiMirrorSystem|anti-mirror targeting]].
-There are several styles of mirror movement, ranging from very simple perpendicular mirror movement to the more complex coordinate mirror movement.
+Implementing mirror movement requires [[One on One Radar|a decent radar lock]].

+The current state-of-art mirror is '''[[PolishedRuby]]'''.
-=== Perpendicular Mirror Movement ===
+== Coordinate Mirror Movement ==
-This is among the simplest and smallest of all movements, though it isn't very effective.
+This style of mirror movement tries to move to a point "opposite" the opponent. It requires a [[GoTo]] method, such as this one:
-This will turn perpendicular to the enemy and move at roughly the same velocity.
-<syntaxhighlight>
+<syntaxhighlight lang="java">
-//Put this code in the onScannedRobot area of your robot.
+private void goTo(double x, double y) {
-setTurnRightRadians(Math.cos(e.getBearingRadians()));
+    /* Transform our coordinates into a vector */
-setAhead(4 * e.getVelocity());
+    x -= getX();
 </syntaxhighlight>
-=== Angular Mirror Movement ===
+The enemy coordinates must then be transformed, before being passed to the <tt>goTo()</tt> function. The transformation depends on the type of mirroring:
-This just tries to move in the same direction and at the same speed as the enemy.
-<syntaxhighlight>
+; Vertical line-reflection
-//Put this code in the onScannedRobot area of your robot.
+: <syntaxhighlight lang="java">goTo(getBattleFieldWidth() - enemyX, enemyY);</syntaxhighlight>
-setTurnRightRadians(Utils.normalRelativeAngle(e.getHeadingRadians() - getHeadingRadians()));
-setAhead(e.getVelocity() * 1000);
+; Horizontal line-reflection
-setMaxVelocity(Math.abs(e.getVelocity()));
+: <syntaxhighlight lang="java">goTo(enemyX, getBattleFieldHeight() - enemyY);</syntaxhighlight>
 </syntaxhighlight>
-=== Coordinate Mirror Movement ===
+== Perpendicular Mirror Movement ==
-This style tries to move symmetrically to a point on the battlefield, usually the center. For example, if the enemy were retreating from the center, then so would the mirror bot(as opposed to angular mirror movement, which would advance toward the enemy).
+This type of movement will circle the enemy, by turning perpendicular to it and moving at roughly the same velocity.
-The following code is from mn.micro.perceptual.Mimic 1.0.0.
+<syntaxhighlight lang="java">
-<syntaxhighlight>
+public void onScannedRobot(ScannedRobotEvent e) {
-//Put this code in the onScannedRobot area of your robot.
+    setTurnRightRadians(Math.cos(e.getBearingRadians()));
-final double headOnBearing = event.getBearingRadians() + getHeadingRadians();
+    setAhead(4 * e.getVelocity());
