Question
I want when player moves the crouser the animation state changes (im using animation tree) based on the crusor placement. here is the code:
@onready var state_machin = animationtree["parameters/playback"]
enum {IDLE, RUN, GUN}
var state=IDLE
var blend_pos:Vector2=Vector2.ZERO
var blend_pos_path=[
"parameters/idle/idle_bs2d/blend_position",
"parameters/run/run_bs2d/blend_position" ,
"parameters/gun/gun_bs2d/blend_position"
]
var anime_state_key=[
"idle",
"run",
"gun"
]
func move(delta):
var input_vector
if aim==true:
state=GUN
if Input.is_action_just_pressed("aim") and gun and on_stairs==false:
aim=true
state=IDLE
velocity=Vector2.ZERO
if Input.is_action_just_released("aim"):
state=IDLE
aim=false
if Input.is_mouse_button_pressed(MOUSE_BUTTON_LEFT) and aim==true and canShoot:
var dir= get_global_mouse_position()-position
shoot.emit(position,dir)
canShoot=false
$Timer.start()
func _physics_process(delta):
move(delta)
animate()
func animate()->void:
state_machin.travel(anime_state_key[state])
animationtree.set(blend_pos_path[state],blend_pos)
Just use the _input()-method:
func _input(event: InputEvent) -> void:
if event is InputEventMouseMotion:
var angle: float = rad_to_deg(global_position.angle_to_point(event.global_position))
# change position in animationtree
ok but how should i change? I dont know what codes use for it, based on the animation tree… based on the codes where should i put this… mate im a noob
This method needs to be in the player-script. Do you have a blend-space2d in the animation-tree?
My problem is i dont know how to change the animation stats via code
and the codes are up there if you need checking
To set the value you would need to run something like this:
animationTree.set("parameters/gun_bs2d/blend_position", input_vector)
and together with the mouse-movement it would look like this (havent tested it, might be wrong):
func _input(event: InputEvent) -> void:
if event is InputEventMouseMotion:
var direction_vector: Vector2 = (event.global_position - global_position).normalized()
animationTree.set("parameters/gun_bs2d/blend_position", direction_vector)
its not working, it doesnt crash or anything, just there is nothing happening
Your path has to be this. You also need a reference to your animationtree:
@onready var animationTree: AnimationTree = $AnimationTree
func _input(event: InputEvent) -> void:
if event is InputEventMouseMotion:
var direction_vector: Vector2 = (event.global_position - global_position).normalized()
animationTree.set(blen_pos_path[state], direction_vector)
You never change the state from “IDLE” to anything else. You have to set the “state”-variable according to current state
No the state changes, he gets the gun, but he doesnt rotate with cursor:
func move(delta):
var input_vector
if aim==true:
state=GUN
I forgot to put it in the codes up there mb
change the input-method to this
func _input(event: InputEvent) -> void:
if event is InputEventMouseMotion:
blend_pos: Vector2 = (event.global_position - global_position).normalized()
it gives me an error"expected end of statement after expression, found “:” instead"
sorry remove the “: Vector2”
may I ask your name? I want to credit you in the credits… this problem has taken so much time and this is my way to say thank you
This is not neccessary 
. If you insist just put HerrSpaten
