I'm trying to animate a series of tiles arranged on a grid that would flip over and show the bottom side. I want them to rotate in sequence but I can't get that to work. No matter what I do, the tiles flip over all at the same time or in chunks of 4 or more.

I'm trying to animate the tiles based on the position of a cube. What can I do to get the tiles to flip over sequentially from one of the corners of the grid towards the opposite corner while staying flipped? Please help!

Here is the geometry nodes setup: enter image description here

And here is the output:

You're using the Y component of the position of a point that is the nearest for each instance.

But this Y position is the position of a vertex of the moving cube. So this is the same for all instances that are in a relative given position from the cube. 4 vertices in the cube share the same Y position and 4 other one have another Y value (in total 2 Y values).

We don't know why you're using Y only here.

Maybe you can use the distance instead or a combination of Y with the distance.

If you want the cubes stay flipped, you need to use a simulation zone, as if not, the cube instance states won't be kept (as recalculated as a simple modifier all the time).

enter image description here

The following setup:

Multiply delta time (the time between two frames) by some speed factor.

Test the proximity (and map range it to some values: optional).

Cumulate a previous rotation (named attribute) with the new value (angle by speed).

Cap it to pi.

Store the result.

And as output, rotate the instances.

(File is 4.0, but the setting above should work in 3.6)

  • $\begingroup$ Thanks for your help! I don't have a reason for using only the Y value, I'll use the X value as well. I did try using distance but then the tiles wouldn't stay flipped, they would flip back once the red cube crossed their position. $\endgroup$

  • $\begingroup$ You mean they should stay flipped once flipped, or the opposite (come back to their original position)? If they should stay flipped, a "simulation zone" may be used for that. $\endgroup$

  • $\begingroup$ Your suggestion works and the tiles flip and stay flipped. Thank you! I am struggling though to animate the tiles smoothly, they are not flipping when expected so I'll keep working on that. $\endgroup$
