I have an object that must move along the spline at a constant speed, regardless of the position of the end point of the spline. Endpoint coordinates may vary during the process. As a test, I attach the last (or intermediate) spline point to the mouse cursor. How to realize a constant speed, regar…

That looks ok, gimme a little while, I’ll post something up…

( distance = 5, speed = 250 ) ( might be factoring the speed at the wrong point though, just checking… ) Naaa, it’s ok :slight_smile:

( ahh, you had ‘local’ on the spline distance… )

Yes. Local coords not being the same as world.

Understand. But but in this case the problem is not that.

I also tried moving the end of my spline while the ball was moving. Still works. Must be something else you have going on… :wink:

Try to make 3 spline points, and attach second point to you mouse cursor, then check it…

How do you mean ‘attach second point to mouse cursor’?

Motion with constant speed along a spline with a variable length in real time
