  I calculate a curve with 10000 points, for better precision. But only drawing the required number of them.

  "Repeat 10000 times" loop runs from loopindex 0 to 9999, and cubic() expression requires a number from 0 to 1. That's why loopindex/9999

  Not sure what you mean. My demo does exactly what you want:

  Change "Splash color" in project properties.

  R0J0hound will probably have the correct answer for you.

  My dumb idea is first to calculate the total curve length and segment length. Then run the loop again for the same curve, calculating distance from the starting point along the way. Once the distance exceeds segment length, draw a dot and reset the distance counter.

  You need to upload it to any file sharing service - Google Drive, Dropbox etc. Then generate a download link and post it here.

  To add to my previous comment - the reason why other character were tripping was probably some minor differences in their animations. If one frame is just 1px bigger or smaller, or the origin point is misplaced, this could cause such problems.

  When using animated sprites, make sure that origin points and collision polygons are identical in all frames. Or create a separate (invisible) sprite, with just one frame, which will act as a character base with Physics behavior, and pin your animated sprite to it.

  You should mention that you are using Construct 2, because the solution may be quite different from C3.

  For some reason you have rectangular collision mask for the bird, and circular for crates. Shouldn't it be the other way around?

  After I changed the collision masks, the bird slides fine for me. It bounces up a little bit sometimes, but its horizontal velocity remains constant.

  It's difficult to speculate what could be wrong without seeing the actual project. You can try helping the object to slide better by applying a small force to the front of it, directed upward.

  Also, enable "Show collision polygons" in layout properties, and check "Collision mask" property for physics objects.

  Have you tried enabling "Prevent rotation" in physics properties for that object?

  Creating another family is the easiest solution.

  You can make your code shorter:

  For each Objects2
  Objects2 Pick Own children Objects
   For each Objects 
   	Set variable children to (children=""?"":children & ",") & objects.object_id

  I assume I can use the same tilemap for multiple layouts

  Yes, you definitely can. Are you by any chance destroying and re-creating the tilemap object in events? This would explain why the tilemap doesn't show the edits from the second layout.

  If this is not the case, please post your project file.
