float2::AimedAngle
Syntax
float float2::AimedAngle() const; [5 lines of code]Returns the aimed angle direction of this vector, in radians.
The aimed angle of a 2D vector corresponds to the theta part (or azimuth) of the polar coordinate representation of this vector. Essentially, describes the direction this vector is pointing at. A vector pointing towards +X returns 0, vector pointing towards +Y returns pi/2, vector pointing towards -X returns pi, and a vector pointing towards -Y returns -pi/2 (equal to 3pi/2).
Note
This vector does not need to be normalized for this function to work, but it DOES need to be non-zero (unlike the function ToPolarCoordinates).
Return Value
The aimed angle in the range ]-pi/2, pi/2].
