I have a Scene with 720 Frames where I want a vehicle to do a circle movement.

The Location controller looks like this.

`float $radius;`

float $radian;

$radius = 450.0;

$radian = 2*PI * frame/720.0; /* not reduced for clarity */

$position.y = 7.0;

$position.x = $radius * cos($radian);

$position.z = $radius * sin($radian);

When I run this scene the vehicle does the circle movement but stops about 10 degrees before closing the circle!

When I define an own variable $pi the vehicle moves the full circle.

Here is my modification.

`float $radius;`

float $radian;

float $pi;

$pi = 3.1415926;

$radius = 450.0;

$radian = 2*$pi * frame/720.0; /* not reduced for clarity */

$position.y = 7.0;

$position.x = $radius * cos($radian);

$position.z = $radius * sin($radian);
