(the paragraphs are enumerated accordingly with the images)

1 - Hello there, I'm facing an issue where I can't get the reference of a node for the creation of a onready var. This node is of an animation tree.

2 - I need it for my update animation function that uses another var to work with the animation's blendspace.

3 - The character works with a state machine for multiple states, and so far, with the simple movement for left and right, it manages to get the input var just right from a virtual class, but I still can't get the anim tree node working.

4 - I already have a var for just that on the script for the main player node, but...

5 - When I try to use it in the script for the base state, I get this error:

6 - That is a code that I used for reference for mine's. When I worked with everything inside the main player script, it worked just fine. But I'm unable to integrate in the state machine.

#

can you show the scene tree for where your bottomBaseState script is?

#

cos from whatever node this script is running, there is no child of name "BottomAnimTree"

#

atleast that's what the error message says

#

The tree for the scene I'm testing the script

#

The scene for the player itself where the script is running.

#

The "base script" isn't running itself anywhere, but these nodes have their own scripts that extends from that script.

#

example

#

ok so "idle", "run", "jump" and "fall" extend that base script?
so that would be why the script cant find BottomAnimTree, because it's not a child of any of those

#

you might be wanting to get the parent, $../BottomAnimTree or something like that

#

#

since the script is starting from those 4 state nodes, you cant go directly to the player like that

#

the .. above means to go up by 1 layer

#

hmm wait, maybe it's just $.. then, sorry i forget exactly

#

it might just be easier to set the animtree inside the _ready() function of the bottomStateMachine script, and doesnt tightly couple the state nodes to the bottomStateMachine node

#

so youd loop through the children inside bottomStateMachine, then assign itself to each of the children's animtree variable

#

i guess try both ways and see which one works best for you

Alright, I'm still trying to get used to working with states and children so that will prob take some time for me to grasp. Thanks a lot for the help!

#

no worries

#

oh right, instead of $.., if you wanted to get the parent, there was get_parent() method
