Question
Hi all. I'm having an odd problem with my code: I cannot get the combatant to move in the x direction under a knockback effect.
I say x direction, because I tried adding a small amount to y, and it DID move in the y. I know eventually I”ll need to figure out the proper knockback math (right now its pretty simple) but I want to make sure the combatant can move in the x direction first.
combatant = character that can enter combat. in this case, the player and the enemies.
the knockback function itself is:
func knocked_back(antagonist):
self.can_move = false
if antagonist.global_position.x > self.global_position.x:
#we are to the left of them
#knockback further left.
velocity.x -= knocked_back_amount
#velocity.y += 5
elif antagonist.global_position.x < self.global_position.x:
#we are to teh right of them
#knockback further right
velocity.x += knocked_back_amount
# velocity.y += 5
await get_tree().create_timer(.2).timeout #magic number
self.can_move = true
and the whole combatant function is:
extends CharacterBody3D
var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")
@export var max_health = 100.0
@export var current_health = max_health
#weir dt hing whre when we export the max health to a different (lower?) number,
#it keeps using 100 for current health?

there are also two scripts that both inherit from the combatant script. unsure if those are relevant or not, they each have the exact same bug.
ty for anyone who can help, or that took the time to read t his
