I'm not sure you can edit a keyframed color in an animation as part of the AnimationPlayer in Godot, at least not easily. What I would recommend is using a Tween node and having it triggered by the animation using a call method track, or even better have a function in your script that is triggered by the animation using a call method track and have that function tell the Tween to change colors. Something like this:
func start_tween_exported_color():
# you will need to add a Tween node as a child of "Button"
var tween = get_node("Tween")
# stop the tween so we can set new properties
tween.stop_all()
# Set the color (I'm assuming you are applying the color to the modulate)
tween.interpolate_property(self, "modulate",
Color.white, hoverColor, 1.0, Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
# tell the tween to start
tween.start()
Then you just need to add a call method track in the AnimationPlayer and have it call start_tween_exported_color on the first frame of the animation.
Also, in the future please refrain from making duplicate posts. Instead, just bump the original post stating you are still having the problem or something similar, as duplicate posting is against forum rules. Thanks!
