When calling methods on nodes in the scene you need to put $ in front of their names. Otherwise Godot thinks you're referring to node's classes instead of actual nodes. It's a good idea to change the default name of a node upon its creation to avoid confusion.
So instead of:

Animateion.play("slide")
Partcles.emitting = true

It should be:

$AnimationPlayer.play("slide")
$Particles.emitting = true

melapelas2048 The node name (from your first screenshot) is AnimationPlayer, not Animation. So you should've put $AnimationPlayer there.

That error message means that $Animation is null, i.e. it's not a valid node reference. The scene tree on the left doesn't show the Player or Animation nodes, so it's not clear why that's happening.

If you add this before the line that's causing the error, it will output the current node's children:
print_tree()
