Question
EDIT: OKAY so SORRY TO ANYONE ALREADY readin this oops. But i DID figure out a WAY simpler way to do it: use an offset variable for the hit box, and add or subtract it from the x to get it to move with the rotation of the player.
the offset var was defined up top, and equals 2 in my case. gonna refine testing but now i know
ex:
if moving:
anim_tree.set("parameters/conditions/moving", true)
anim_tree.set("parameters/conditions/not_moving", false)
#rotate if we are not going the right way
if velocity.x > 0.1:
#move to right.
melee_attack_zone.global_rotation.y = 0.0
melee_attack_zone.position.x = hitbox_offset
model.rotation.y = 0.0
elif velocity.x < -0.1:
melee_attack_zone.global_rotation.y = PI
model.rotation.y = PI #we should ALSO rotate the rest of our character i imagine!!!!
melee_attack_zone.position.x = -hitbox_offset
I’m trying to create a platformer in 3D, which is probably not my best idea but its what I’m doing right now. I’ve got some code down that let the character move, and had a bunch of trouble when I tried to actually limit the characters rotation (as opposed to setting it directly).
When I set it directly it looked very jittery, and would go back and forth between left and right very fast. This also messed up the camera, so I had to do some code to decouple the camera from the player. I hope that’s not what the problem is, but I’ll share camera code too, just in case.
the part I THINK the bug is in is in this specific part,
func set_animations(delta):
#rotation
if moving:
anim_tree.set("parameters/conditions/moving", true)
anim_tree.set("parameters/conditions/not_moving", false)
#rotate if we are not going the right way
if velocity.x > 0.1:
#move to right.
#melee_attack_zone.rotation.y = 0.0
if self.global_rotation.y > 0:
#magic number alert
self.global_rotation.y -= 5 * delta
#tryin some thing new: we are goin to rotate quickly instead of just one flip
#if self.rotation.y != 0:
#current_y_rotation += -.1
#model.rotation.y = 0.0
elif velocity.x < -0.1:
if self.global_rotation.y < PI:
self.global_rotation.y += 5 * delta
#self.rotation = Vector3(0, PI, 0)#THIS doens't work, though the above one does :O
#weird
#if self.rotation.y != PI:
#current_y_rotation += .1
# melee_attack_zone.rotation.y = PI
# model.rotation.y = PI #we should ALSO rotate the rest of our character i imagine!!!!
self.rotation.y = clampf(global_rotation.y, 0, PI)
But the whole script is :

if body.current_team == teams.ENEMY:

#take into account other, non basic attacks later
#we need to make whoever entered this take damage, if they are an enemy
The camera script is :
extends Camera3D
class_name CustomCamera
#@export var zoom = 1.5
#var min_zoom = .5
#var max_zoom = 3.0
#var zoom_speed = 0.1
@export var TargetNode : Node3D = null
func _ready():
pass
func _process(_delta) -> void:
set_position(TargetNode.get_position())
position.z = 8.0
but i’m mostly using it atm to set the z position farther away from teh character.
this all started because I was just rotating the model originally, but couldn’t rotate my box that detects enemies (hit box? Forget the word, sorry. Its so the script knows if an enemy si in that box and can apply damage to the enemy )
I feelliek I’m VASTLY overcomplicating this , what i really want is to rotate taht box and the model can also rotate if it wants. But i’ve way overcomplicated the problem so I’m not sure what I’m doing wrong atm
thanks to anyone who took the time to read this and anyone who can help
