Ramp colour change of object

use the animation puzzle with the set color puzzle

you can use numbers puzzles to change the R G B values..

also, back in blender, you can plug a value node into the “fac” input of a mix rgb or mix shader node, name it it’s NAME field (right panel in node editor).
then you can use that NAME in animation puzzles using “updated value puzzle” (very important puzzle) IN whatever’s animating.

here’s the user manual for animating materials etc…

then under that, next step up, procedural animation

if you want to activate those animations on input…
then.. put those animation puzzles in a procedure puzzle (use these for everything they are “functions”, the “blocks” javascript scripts are made of mostly.

… then put procedure link (right click procedure to get it) in the “then” (empty space inside of) “if logic puzzles”

or when clicked puzzles..

or you can put those animations just inside the if/ then logic puzzle. (better in procedure for control and future use/re-use)

(lol k done editing my mistakes a million times)
ENJOY!

you should convert the current X coordinate of your cube to the mix factor, using some simple math

glad you worked it out!
