2D Platformer Attacks and Enemy Setup ~ Godot 4 Tutorial

[@Psydefex]

cant express enough how grateful i am for you taking the time to make these tutorials brother. i have 0 programming knowledge and was able to get enough from these to mess around and make some cool shit.

[@OHMSdev]

took me about 2 weeks to finish this course in my free time. Im grateful for the work you've put into this. I hope to see more done on your channel with godot4!

[@kuangmengg]

I love how thie video begins by explaining what are we going to expect follows by some of the basic mechanics instead of many tutorials straight jump into the editor and coding to leave the viewers wonder if those tutorials are what they need. As a complete godot beginning, it definitely give me a good guide

[@NicholasKJ]

This course is incredible! So well structured and clearly explained. For damaging the enemy, instead of creating the Damageable class and looping through all of the body's children to find if the body has that class, I like to use `body.has_method("take_damage")` and implement a method take_damage(damage : float) in any character I want to be 'damageable'. Much more performant than looping through the children of every body you collide with. Thanks for the course! :)

[@khzzzzzzzz]

Please keep uploading this longs videos! I'll watch in detail!

[@CosimoDavideViggiano]

What I love about your tutorials is the fact that you show how to resolve my same issues (chain attack, multiple sprite sheet for animations, sprite offset, state machine etc). I really appreciate it. Other tutorials are somehow done ad hoc with their assets, your is most realistic ever. Thank you.

[@davidank07]

FYI if you ever have to change the name of a variable, if you highlight it and hit ctrl R (cmd R on Mac I guess) it'll give you a prompt to set the new variable name and replace all so you don't have to go searching for it.

[@gamma3501]

thx I thought it wasn't cause they forgot to add it on right-click menu

[@richardsymes8473]

with reference to the flipping of the sword collision shape, a much simpler solution is to add this code to the update_facing_direction function func update_facing_direction(): if direction.x > 0: sprite.flip_h = false if sign( collision_shape_2d.position.x) == -1: collision_shape_2d.position.x *= -1 elif direction.x < 0: sprite.flip_h = true if sign( collision_shape_2d.position.x) == 1: collision_shape_2d.position.x *= -1

[@Ceseleone]

hmm why not just change X position in the same code when you flip the player sprite?

[@raoinshishiza152]

[@pascalcasier959]

Thank you so much for continuing this tutorials

[@WeirdGoat]

Great work! Really recommend you to make a HitBox & HurtBox scene, so that you could use them in almost everyone of your game with just a little modification

[@Jestertdye]

These tutorials are so great! All other ones that I try and watch are in a previous version of Godot. You’re awesome!!!

[@corecore1572]

Exactly! The software is updating so fast that previous tutorials are almost useless now. They follow the same principles, but to a beginner it's quite confusing.

[@lenonkitchens7727]

If you go through the trouble to set up a state machine, each state should handle playing it's own animation in it's on_enter() function. That way you only have to set up the next state, and never have to remember to call travel() to change the animation as well.

[@malcolmcolindixon]

Don't get me wrong I've learned lots from this video and the previous one BUT I really feel liked you messed up use of the state machine, like playing animations for the next state when these obviously should have been in the on_enter for the next state. Jump logic in the Ground state where there should be a Jump state IMO. Just like you did the state_input and state_process I added an on_animation_finished too, which was useful in the Attack state and Dead state which helped to simplify the code. Adding a previous state parameter to the on_enter method was really useful too for the Attack, InAir and Hit states.

[@PopMusicKiller]

I agree. This stopped making sense when I found myself switching between scripts every few seconds to troubleshoot implementing a climb state.

[@acidjuice]

These videos are honestly so helpful for learning about godot!!!

[@noiJadisCailleach]

55:20 Except, we don't get the death animation. The snail turns immortal instead. Update: If you have the same problem, it was a node naming and calling discrepancy. I straightened that out and it worked. I had 2 other typo related problems that gave me errors after this timestamp. Fixing all of those got me to the end of the vid, following along. I followed along with Godot ver. 4.0.2. Best of luck to everyone else!

[@lew-tn8yd]

Hi Noi :) I´m having this same issue, which node is causing you problems?

[@vasiliykorn4485]

I have had the same issue. First of all don't forget to assign right Nodes in right places and yeah ... be careful with variables naming. I did mistake in signal name (made it like function for another node) it's caused a lot of problems) Get luck!)

[@adrianpassarelli4511]

didi you solve it? mine only works on the first hit of the first mob, then no more knockback again

[@ajcar110ify]

Great idea with how you handle translating the position of the hitboxes. i had been using one for each side and activating or deactivating them depending on the direction the character was facing. this is much better.

[@WalkerRileyMC]

The method I used was to add an @onready variable to the sword collision shape right in the player script, then under the existing update_facing_direction method I manually repositioned the collider using collision.position = Vector2 (x,y) for right and (-x,y) for left, with y not changing its value. I'm sure that'll bite me eventually, but it seems to work fine and doesn't require additional scripts and signals. I guess if I ever wanted to adjust the collider i'd have to manually update it....hrm..

[@HansChristian-bj2pt]

Awsome tutorial, an option for the change of combo attack animations is to use the animator. This can be good if your attack animations have a recovery animation included that you ither want to skip or make it so you cant combo when the recovery starts. Ofc some change to the code is also needed if you go this route, if anyone wants to try it you have to split the functionality in the animation_finished function and create another function, mine was named Combo and also a bool that is Exported so the Animator can set the bool, this is used instead of a timer so you can get rid of that one. Then the Animation Finised function only handles the Next_State if the animation have finished and only returns to the return state. The Combo function is activated when you press the attack button while the canCombo bool is true (that gets set in the animation keyframes) and it checks for what node is currently active. As an example it attack_1 is active the attack function would call playback.Start(attack_2).

[@hbora8339]

Hey mate, these tutorials are fantastic. I've been following you all the way and i've learned a ton, so massive thank you. The pace is difficult to keep up with though! I know you've got a lot to get through, but spare some thought for me in the next one xD

[@alexandern9353]

I'd expect all the state machine stuff to actually help write correct animation transition code. But in the end it's just a mess of configuration properties, inherited properties, string properties, "playback" of arbitrary strings, etc. No actual constraints. And why is there an on_enter() defined at all? "State machine" more like rube goldberg machine.

[@strathallanguy]

I enjoyed the speedy snail bug 😁

[@AzoTheRed]

These videos have been awesome, but I have one thing to mention. I have decided to put the animation call into the on_enter() function. To me, it feels like it makes more sense that way. I don't know if that is going to cause me issues in the future, but we will see.

[@Coruja182]

[@Ceseleone]

how can I add the attack while jumping? only attacking on the ground cancels the option of any flying enemies

[@tenorsrfun]

Great tutorials, been following along to learn Godot. Is there a reusable way to do the animations? It seems tedious to have to add the texture, hframe, and frame every time on the animation player per animation. Is there way save that shape and reuse it for additional animations? Essentially for each animation to extend some class I create that has those 3 properties?

[@raoinshishiza152]

what happened to the hitstate code at 50:55? it went from exporting a var to connect the state machine to not having one?

[@noiJadisCailleach]

At this part of the vid, this is actually the third time this has happened. Don't bother waiting for replies. I feel that he's actually posting these vids mostly for himself, so he could review it later when he's forgot something. And we, the audience, are just bystanders who happen to see his shit.

[@itsthefortniteguy]

I have a problem, the snail doesnt play the walk or dead animation, i already checked if the code was the same as the video Edit: It also continues moving after being hit Edit 2: It has no knockback

[@QuestKnightTV]

Can we get a follow-up tutorial on how to improve the enemy? Change direction instead of falling off platforms and attack player?

[@michaelwaldsmith495]

Following along with the downloadable project file. Whenever I open the animation player and hover my mouse over the "frame" track, it instantly changes all the frames to the "Idle" animation. This might be a bug from updating the project from Godot 4 to 4.3. Any suggestions to fix? I'm trying to replace the sprite animations with my own sprites.

[@RafaMartinelli]

Brilliant, I followed all the tutorials and after troubleshooting a couple hiccups I was able to complete it. I only had 1 small issue with enemy knockback: the original enemy gets standard knockback but the duplicates get a very tiny knockback. Any ideas on what might be causing this issue? 🤔

[@carkelvisar4821]

On 9:33, why did you change names from attack_animation to attack_node? Is there some convenction that I missed?

[@Ears1020]

I am at a complete loss. I have been through the code several times and for some reason, my character gets stuck in the "attack" state (~16:10). In the video his animation is stuck, but the State shows that it has returned to the "ground" state, but I am stuck in the actual "attack" state (based on the debug label) and I can not find where I made an error or what I missed. Everything looks identical to his code but it is not working.

[@jonathanbernardi4306]

Amazing journey this series, lot of knowledge and the logic behind the commands, this been priceless. For the sprites not having the same position, I fixed mine by adding a keyframe to position and adjusting each animation accordingly, not sure if that´s a correct way, however been working good so far.

[@HamsterAccent]

01:16:24 Has anyone else had luck being able to implement character damage like he suggested? I added a damageable to the player, added the hit and dead states to the player's state machine, added the death animation, and added a hitbox to the snails (using code that's basically copied from the sword while adding a bit that only hits the player), but I haven't gotten it to work yet. I feel like I should just be able to copy the nodes and add all the necessary things, but that doesn't appear to be the case. Anyone able to help? Please and thank you! EDIT: Nevermind, I realized that I hadn't connected the hitbox to the body entered signal. It works now!

[@AxZelAnimations30]

This is similarly what I used to do in Unity. Except some of the scripts that needed Timer are basically done in the AnimationPlayer itself. I guess Timer is alot more useful when you're in a game where Damage Per Seconds are important. But I have not seen anyone do a Root Motion in 2D. I know it can be done without actually using Root Motion feature, just the AnimationPlayer and a Node as the Root Motion, but I'm still planning on how it should be done.

[@horohoro1836]

Thanks for the tutorial :DD

[@articrus9418]

Have I been the only struggling with 1:00:27 ? I put the check_if_can_move method in but it doesn’t seem to work in stopping the snail when it gets hurt. Nor does it seem to ever register as false when it gets hit, despite the hit state saying it should Edit: Nevermind lol. Just had to re-position one line and it worked perfectly

[@PebroGon]

Hey, I applied the "damage indicator" from this tutorial on the enemy in my game, but when it gets hit , the damage gets indicated in one spot on the tile of my game, not on the enemy itself. How to fix it please?

[@APRI_Music]

Hey, when I attack the snail after adding the collision for the right side, the knockback on the snail only moves left after being hit?

[@HQ_Default]

Since the "damageable" node is only there to provide confirmation of a "hit" function, is there any reason to specifically use a node instead of creating a generalized parent enemy script that the snail would inherit?

I have attack1 and attack2 animations with 4 frames too, timer in 0'3s. But it's impossible to chain the double attack for me. It's something related with my attack button speed press?

[@SosumiInc]

1:01:00 I had to remove the type on "var direction" in order to make it not complain about "Invalid operands Vector2 and bool for 'and' operator". Godot 4.0.2 in Linux For some reason, it didn't want to check whether or not 'direction' was nonzero. I'm sure I did something wrong, as on_enter() isn't working in any class, either. Another (waaaaay simpler, IMO) way of handling the sword collision flipping left/right is to modify the player's "update_facing_direction()" script to have "$Sword.scale = Vector2(-1,1)" when facing left, and Vector2(1,1) when facing right (naturally, make an @onready for $Sword and change accordingly).

Where an what is the playback var? i dont see it anywhere.

[@ReversedShadows]

So when my enemy damage numbers pop-up, they aren't originating from the snail's y-coordinate location. Instead they're appearing well above it, like barely in the top of the screen. It does appear above the snail regardless of its x-coordinate (as it moves to the left). I would assume the issue would likely be within the health_changed_manager here: func on_signal_health_changed(node : Node, amount_changed : int): var label_instance : Label = health_changed_label.instantiate() node.add_child(label_instance) label_instance.text = str(amount_changed) Since that's calling back to the "Snail", right? But I can't see any reason why it isn't functioning the same way since there isn't any y values in that script nor any available/changed in the inspector.

[@matthewmatteomatheus6483]

Reset all the anchor points in the inspector. Go into HealthChangedLabel, click on the label, in the inspector tab, open the Layout panel and reset all Anchor Points and Offsets.

[@neilwalker4277]

Superb series. Couple of things and one coding suggestion, maybe you've done them in later videos... You can drag nodes into editor to create unready vars. Gdscript has ternary statement. Gdscript has an idle/frame skip function, to save on that timer waiting a frame. Using get_parent() is a bad thing generally, it adds tight coupling and stops you testing in isolation. Also, if nodes change position, code fails. For your Damagable maybe look at HeartBeast hit/hurt box video. One last thing on Damageable, you fix/set damage value in the node, would be better for hitter node to send damage amount or a damage scale factor, e.g. Sword, gun, etc

[@raoinshishiza152]
