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);
