Apologies for the newbie question. I just started working on Godot, and this happened to me twice. I was working on the tut "Your First Game" in the docs. I made it up to the point where I was working on the Main Node, and was about to start the HUD. I tested the game, as instructed, and I get a blank screen? I removed that project yesterday, and redid it today and got the same result. No Player, no Mobs. I am using the latest stable release of Godot. Here is the code for Main, as this one is most likely the issue.I wish I could tell you more, but I don't have a clue what I did. Any help, please? Thanks.
export (PackedScene) var Mob
# Called when the node enters the scene tree for the first time.
# Called every frame. 'delta' is the elapsed time since the previous frame.
score = 0
score += 1
$MobPath/MobSpawnLocation.offset = randi()
var mob = Mob.instance()
var direction = $MobPath/MobSpawnLocation.rotation + PI / 2
mob.position = $MobPath/MobSpawnLocation.position
direction += rand_range(- PI / 4, PI / 4)
mob.rotation = direction
mob.linear_velocity = Vector2(rand_range(mob.min_Speed, mob.max_speed), 0)
mob.linear_velocity = mob.linear_velocity.rotated(direction)
