		</method>
		<method name="angle_to">
			<return type="float" />
			<argument index="0" name="to" type="Vector3" />
			<description>

		</method>
		<method name="bounce">
			<return type="Vector3" />
			<argument index="0" name="n" type="Vector3" />
			<description>

		</method>
		<method name="cross">
			<return type="Vector3" />
			<argument index="0" name="b" type="Vector3" />
			<description>
				Returns the cross product of this vector and [code]b[/code].
				This returns a vector perpendicular to both this and [code]b[/code], which would be the normal vector of the plane defined by the two vectors. As there are two such vectors, in opposite directions, this method returns the vector defined by a right-handed coordinate system. If the two vectors are parallel this returns an empty vector, making it useful for testing if two vectors are parallel.

		</method>
		<method name="cubic_interpolate">
			<return type="Vector3" />
			<argument index="0" name="b" type="Vector3" />

			<argument index="3" name="weight" type="float" />
			<description>
				Performs a cubic interpolation between this vector and [code]b[/code] using [code]pre_a[/code] and [code]post_b[/code] as handles, and returns the result at position [code]weight[/code]. [code]weight[/code] is on the range of 0.0 to 1.0, representing the amount of interpolation.

			<argument index="0" name="b" type="Vector3" />
			<description>

				Returns the dot product of this vector and [code]b[/code]. This can be used to compare the angle between two vectors. For example, this can be used to determine whether an enemy is facing the player.
				The dot product will be [code]0[/code] for a straight angle (90 degrees), greater than 0 for angles narrower than 90 degrees and lower than 0 for angles wider than 90 degrees.
				When using unit (normalized) vectors, the result will always be between [code]-1.0[/code] (180 degree angle) when the vectors are facing opposite directions, and [code]1.0[/code] (0 degree angle) when the vectors are aligned.
