Hi, All.
The anim editor does not recognize Color as a variable though it is supposed to animatable (Error: Line1: Unknown Symbol 'Color').
Has anyone tried that? Is this a bug or it's just me? Thank you.

which op ?

Yellow Sprites op.

it looks like a problem between the color type and the name (type color exist in script)

Yes. That's the problem. Anything can be done about it?

no problems in there, define splines to animate

thanks for the hint, but how do I bind a spline to the variable (*Color) that can't be recognized as such?

I think there is really a bug with sprites color, with conflit name/type. I've renamed Color param to Colora for testing
And script now working. However it's not very intuitive to anim color with spline :p

Great! Well done. It works! Several off-top remarks though:
1. Do you think this change will not conflict with older wz4 files?
2. Will you post a pull request for this change?
3. What is [0..3]? Some sort of interval for the spline (or its point count?) I guess... If I set it to smth 0..2 or 0..4 it doesn't work...
4. No big deal, but Calora seems a bit less obvious than Colors. Can you call this variable just "Colors"?

I noticed that Color type conflicts in any op that uses Color as a variable.
Same goes for animated tetures. Take a look at the example. Maybe the type itself should be renamed?

But what about compatibility then?...

OK, guys! I have found the answer!!!
Use 'color_' variable to animate colors!
Many thanks for your help!!! Closing the issue.

could you share an example please
thks

With pleasure.
