How to adjut this code to set it to a fix movement speed (spline/timeline)

Hello Clock,

back on this project I noticed that one piece of the track, the curve, is shorter than the straigt one (the spline, not the mesh - obviously, did not came into my mind before, sorry)
I assume that the speed difference while adding and adding tracks ingame comes from this.

So instead of having a set value of 100 I do the following:
Get spline length before updating the spline = Old Spline Length
Get spline length after updating the spline = New Spline Length
New Length minus Old Length = Added Spline Length.

So I still use your formula but instead of 100 I use the value added Spline Length.
In my head this should work for both the straight track part and the curve part. But it feels that the car speed is still not constant.

Any last idea? Do I need different calcs when adding a straight part and a curve?

Hi - sorry, best if you quote people, then they get a notification.

I tried to find a way to automate this for you, but there isn’t one. It’s because you’re using a timeline.

So - here’s my offer. I’ll show you how to do it with tick. If you use tick, once you’ve set it up, you wont have to every touch the speed after editing the spline.

Sound good?

Here we go. Change your BP that moves the cart to be like this:

And you make a function to calculate the spline distance like this:

( you’ll need to tick the pure box in the details ).

Two variables, speed and distance. You don’t need to touch distance, just make the speed variable visible in the viewport and you can tinker from there.

EDIT: Better version of the BP:
