[[:Multiple_return_values|This function returns multiple values.]]

===== Description =====
Returns the 2D vector rotated by angle.

===== Examples =====
<code>
RotateVector(x, y, angle);
int newX = r1;
int newY = r2;
</code>

Rotate a point around the origin
<code>
RotateVector(x - originX, y - originY, angle);
int newX = r1 + originX;
int newY = r2 + originY;
</code>

<note tip>Use [[RotatePoint]] instead of the example code above.</note>
