PI is wrong?
« on: October 11, 2008, 03:59:49 am »

I have a Scene with 720 Frames where I want a vehicle to do a circle movement.
The Location controller looks like this.
Code: [Select]
`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.
Code: [Select]
`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);`

What version of Anim8or are you using? The PI value should should be correct in v0.97d.

Sorry, I had an old version (0.95c).
With the newest version it's OK.
Thank you!
