[@FeralGinger]

THE single clearest video on state machines so far - thank you.

[@just_a_zombie6718]

REAL! i read the code and boom i learned how to make StateMachine. there should be a tutorial on the video title on his every finite statemachine video for more views

[@Peter-wl5xm]

Thank you so much for your tutorials. The parenthesis giving detail to what each block of code did really helped me. Thanks again.

[@8_bit_gamer278]

Thank you for giving these tutorials. You are really a big help right now. Thank you

[@Soroosh.S83]

Your music choice for background is awesome

[@MilkyGees]

omg this is super helpful, I am working on enemies for my game and I wanted to make a simple state machine. Thank you!

[@user-tc5yk4zd5k]

Thank you very much!very helpful!

[@lofinotion]

for a beginner like me, it's so helpful, thank you so much

[@wolfHKS]

oh wow new video , it good . Thank you !

[@weregoat529]

Great tutorial, a lot of the code has come in handy for me outside of FSM too :)

[@handemonizer6547]

This actually work for me. I type every script without copying the codes and it is actually working. I am really glad.

[@truonghai9999]

thank you

[@CurtisParhamFreeSkills]

Thank you for your video. I'm trying to follow along. Any idea why my RayCast2D would be point above my player. Then when I get close it points away from the character? I'm new to Godot and game development in general, but not new to programming....but I obviously am doing something wrong

[@CurtisParhamFreeSkills]

I figured out something that worked I had to do this direction = (player.position - position).normalized() instead of direction = (player.position - global_position).normalized() not sure why it didn't work while following your code example.

[@FeralGinger]

I tried added a func kill to this and my enemy kept following me around in the dash state (was pretty funny). I then tried to make a deathstate to change to but can't quite figure it out, what do you recommend would be the best method?

[@BrunoFernandes_84]

hi, can u give a little help, after i follow the tutorial i set the boss to disapear on death, but it has a bit of delay because if i kill the boss in the moment he's dashing it plays the death animation and disapear in the middle of the dash. any ideas on how to fix it?=

[@moonnight9474]

😍😍😍😍😍😍😍😍😍

[@floraphonic]

great video. let me know if you need any sound effects. would love to collaborate

[@16bitdev]

Sure! Join my discord, I will message you when I make a game in the future. Invite link is in the description.

[@hanzelibardo2242]

thanks for this tutorial, can you make a tutorial for switching weapons including their, sprite, damage and attack speed?

[@hanzelibardo2242]

Im all good with my request 😅, I'll just follow your tuts on bullet hell, thanks man, more power to you

[@Peter-wl5xm]

Hello! Was there a method for increasing the size of your bee without changing the scale? Mine is really really small. Thank you!

[@16bitdev]

go to project settings> window> set viewport size to 320x180, turn on advanced settings> set override to 1280x720, scroll down set stretch mode to canvas_items

[@giancarloapango]

Hello, i have a question, Is there a way i can reuse the state machine, for example one enemy has. Attack, idle states AND another one has other states but the both use the same state machine code but of course other states codes?

[@16bitdev]

yes make a base enemy with attack and follow, then make an inherited scene with this and add more state in the inherited scene, with this you can make multiple variations of enemy

[@dingusbrule5756]

[@bradexoff7584]

I don't know how to make the State node connect with the StateMachineNode '-'

[@16bitdev]

add a node 2d to StateMachineNode, add a script to it, but make sure its inheriting the state by selecting state.gd from the drop down menu

[@machkiboaiak1998]

I think add two more states to the boss, perhaps spawning 2 minions and a special ability of some kind.

[@16bitdev]

That sounds cool! I will try to do it.

[@GothicRK]

In 8:48, why is it necessary to put owner.set_physics_process(true) AFTER already putting super.enter()?

[@16bitdev]

we are dealing with 2 physics process, one that controls transition in the state which is super.enter(), second is the owner's physics process that controls move_and_slide(), so we need both of them

[@GothicRK]

@@16bitdev oooooh I see now! Thank you so much for the explanation!

[@greenstarsproductions5968]

Uh. When im doing var current_state: State. It says “could not find type “State” in the current scope”

[@16bitdev]

you have to make a class State first, or else it won't find it, make sure you have written "class_name State" in your state script, this will solve the issue

[@greenstarsproductions5968]

@@16bitdev I did

[@memumemu7539]

[@mamuszgaming2509]

I'm at 4:46 and when i started the testscene it crashed and said "invalid operands'Object' and 'Vector2' in operator '-'."

[@16bitdev]

Give me the script name and the line number where its throwing the error

[@16bitdev]

this error happens when you subtract object with vector2, they are 2 different types, I am guessing you did (player - global_position) in the boss script, instead of (player.position - global_position)

[@teammerdoss6234]

I can't use "find_child". Is it because I used Godot3 😢

[@16bitdev]

i think in godot 3 its find_node
