Question
hi, so I am making an fps game. then i started on the kill part, but now it is giving me an error for invalid get index 'receive_damage' (on base: 'staticbody3d'). , eventhough I am using an playerbody3d. can someone help me.
Here is the code:

var speed
var CROUCH_SPEED = 3

const JUMP_VELOCITY = 5.5
const sensitvity = 0.01
const SPEED_SPRINT = 10.0
var default_height = 1.5
var crouch_height = 0.3
const bob_freq = 2.3
const bob_amp = 0.08
var t_bob = 0.0
var health = 200
