I have a skeletal dragon mesh playing an animation in which I am trying to get to fly around. Using a spline, I laid out a path for it to follow before ending over some mountains. However, when testing, the dragon stays in the same location (XYZ) and spins at like 1000 RPM. I have a screenshot of the BP and the Timeline. I noticed when setting the ‘Distance along spline’ nodes to Local instead of World, the dragon doesn’t rotate, however it stays at the 0,0,0 location on the level. Any help would be great! Thank you.

You forgot to put up the BP.

But my favorite theory is you’re using some sort of add location or add rotation node on a timeline?

You have to use the ‘set’ versions with a timeline.

Thank you for reaching out! I rushed the question out as I was in a hurry. I put up both the BP and timeline, so hopefully that helps find the exact issue. I’m getting the values of the spline paired with the timeline and using 'Make Transform", sending those values to ‘Set World Transform’. It’s making sense to me logically, but I’m getting a dragon helicopter in hyperspace.

I think you must have something else going on.

I’ve got EXACTLY the same code here, with a skelatal mesh, and it just follows the spline…

Ok, I give up.

I have exactly the same code, and it works.

Couple of Qs:

  1. Is the dragon just a static mesh?

  2. Was the spline created in the BP with ‘add component…’ → spline?

  3. Can you try it with a plain static mesh ( like a cube )?

  1. So the dragon is a Skeletal mesh playing a looping animation. The whole plan was to have it just fly in, fly around, and fly away.
  2. The spline was created in the BP with add component
  3. I tried it with a static mesh cube while waiting for your response and while it doesn’t spin out of control, it flies away and keeps looping back around above the level going higher and higher until the timeline ends.

Have you tried it by simplifying the spline? Maybe the spline is the problem…

The only way I can get it to do anything crazy is the use the mesh to parent the spline.

Ah. That was it. Can’t believe I overlooked that. Sorry for not putting that in the picture. I thought for sure I botched the code somewhere. Thank you for the help! I appreciate it!
