			{{g\|vecx}} and {{g\|vecy}} are two commonly-used GScript functions which help calculate positions based on a direction.

			vecx(dir) - returns the amount a player would move on the x axis if moving in direction ''dir''
			vecy(dir) - returns the amount a player would move on the y axis if moving in direction ''dir''

			The amount is based on a player speed of one tile per movement. You can multiply the returned value by your desired speed to find the appropriate movement delta for your situation.

			== Reference Table ==
			{\| border="1" cellpadding="3"
			! Direction
			! vecx(dir)
			! vecy(dir)
			\|-
			\| {{g\|0}} (up)
			\| {{g\|0}}
			\| {{g\|-1}}
			\|-
			\| {{g\|1}} (left)
			\| {{g\|-1}}
			\| {{g\|0}}
			\|-
			\| {{g\|2}} (down)
			\| {{g\|0}}
			\| {{g\|1}}
			\|-
			\| {{g\|3}} (right)
			\| {{g\|1}}
			\| {{g\|0}}
			\|}

			== Example (Staff Boots) ==
			//#CLIENTSIDE
			function onCreated() {
			this.speed = 1;
			}

			function onKeyPressed(code, key) {
			if (key == "b") {
			// toggle boots
			this.on = ! this.on;

			if (this.on) {
			this.trigger("timeout", null);
			}
			}
			}

			function onTimeOut() {
			if (! this.on) {
			return;
			}

			for (temp.key = 0; key < 4; key ++) {
			if (keydown(key)) { // is the key down?
			// move the player in the appropriate direction using vecx and vecy, multiplying
			// them by the current speed
			player.x += (vecx(key) * this.speed);
			player.y += (vecy(key) * this.speed);
			}
			}

			this.setTimer(0.05);
			}

			function onPlayerChats() {
			if (player.chat.starts("/speed ")) {
			this.speed = player.chat.substring(7).trim();
			}
			}
