2D Enemy AI: Game Builder Garage Tutorial

[@fallout187]

I liked how you cleaned up the sprite cycles. Everything feels very organized and customizable. Thanks for taking the time to make these videos.

Yall are getting some good views now. Im glad! Yall have been working hard

Thank you Boi! I’m very glad too, we’re really enjoying our small growing community here on the channel!

[@cashmoney3882]

Very underrated channel. Really informative and entertaining! Good job dude!

Thank you! I really appreciate your support! I’m glad you’re enjoying our content!

How do I make the background also 2d without there being a shadow from the sprites?

[@CryOverdage]

you can put the 3d objects below the ground and use the top for the sprites. or you choose on which side of the object the sprite should be visible. you can do that in the texture nodon on the top left.

[@doctorjeffury8722]

Go to the world nodon and change the sun to be under the world

[@L1N3R1D3R]

You can optimize the walk cycle programming with Marker and Bull's-Eye Nodon instead of the Digitize, Constant, Comparison, and AND Nodon. This is especially efficient if your walk cycle is more than two sprites.

[@AllDaBois]

I’m really glad you brought this up. Yes I do plan on making some new videos on integrating the marker nodons instead of the digitizer system. The recent discoveries people have been making with them is definitely going to help clean up peoples code. I’m glad loup&snoop took the time to make his marker tutorial the other day

[@alexgamer1287]

4:53 for my remind

[@eelmail2077]

What about an enemy that walks all the way around a platform like the crawlers in Super Metroid?

[@theflameviper2154]

Or like buzzy beetles and spinies

[@aliyahwilliams3179]

I guess you're still working on that kart fighter like roster. Like I was talking about actual fighting characters like the can actually hurt you using their moves. I will be waiting and I hope it will be good!

[@EthanBus]

Yeah same I am making a mortal kombat remake

[@AllDaBois]

Yes I am, as of now my next video will more then likely be on setting up a character select screen. But I plan to continue setting up fighting game style mechanics. I’ve got a general program made up for it. Hoping to get things finalized once I get some more time.

[@fawfulthegreat64]

How do you make the turning speed slower, Paper Mario esque instead of instant? Also, how do I make the hitboxes (touch sensors and destroy objects) move horizontally with the enemy but NOT rotate when it does? IE the enemy walks back and forth and turns around but the hitbox just changes its direction without also flipping. I'm trying to work this into my SPM flip system, so my hitboxes need to extend across the entire depth of the level (I want to disable them entirely when the 3D flag is on), and I don't want a giant hitbox that swings around and hits the player from far away when the Goomba turns around.

[@AllDaBois]

In order to reduce the turning speed you may have to use Player Nodon instead of Moving Object Nodon, although it’d be difficult to define who is supposed to die upon getting hit. Because you can reduce the turn speed on the player nodon, but not the objects. Alternatively you might be able to stick a counter right before the angle nodon, if you can have a very low input value going to it for a certain duration of time you might be able to slow it down that way. I’ll have to give the hitbox question some more thought. But maybe you could have 2 on the enemy, one that goes the entire length and one that does not. Then you could switch which one is active depending on if they are in the 2d view or the flip side view. I’ll let you know when I come up with something to fully help you with your question. But I hope this helps.

[@spaceman300]

Another brilliant video

[@AllDaBois]

Thank you! I’m glad you’re liking the tutorials!

[@montymole297]

When I build the "Basic Follow" enemy, it always goes right, never left. Is there a solution for this? I think that I've programmed it perfectly.

[@beatrizromeromartin2603]

Incredible 👏👏❤️❤️❤️

[@lord_caccum]

Thank you so much!! Also when is the checkpoint video coming?

[@AllDaBois]

No problem! It should be out sometime within the next week. I just thought of a clever way to make the checkpoints function. I just have to put it in the game when I get some time.

[@zachcapricorn3512]

Mabye how to move to a random pos. is with the help of the random nodon. Hope that makes sense.

[@Jake-nq8kp]

Can you make a video on how to move objects in increments?

[@elmarakovideo]

Thanks for your tutorial. Is it possible to grab and throw an Enemy in a 2D Sprite platformer?

[@AllDaBois]

It might be possible if you link a throw command to rapidly increase the moving Object on the enemy for the throw. But it would take a lot of thought to get it properly executed. It is something I might look into in the future though. It’d definitely be great for fighting style games

[@elmarakovideo]

@@AllDaBois Thanks for your comment. You should make a short demo with Mario sprites: "How to pick up and toss a Shyguy."

[@billgates3087]

Mine went on turbo mode for the one that paces

[@thantrus]

I don't know how tall of an order this might be, but how feasible would it be to make enemies like in a Beat'em up like Double Dragon? No damage on touch, but enemies that throw punches/kicks and have HP as well?

[@Slimeyalt]

my enemy wont move even thou i put the same code as you i even looked in your game and my dosent work it just stands there while the animation goes i can kill it but it wont move.

[@Sebastiansandwich]

My enemy just went SPIN NNMNNNNNNNN

[@frogkidmotion2889]

what about like a bird that flies around a area

[@brunobauer4383]

heey so i didnt add a sprite cause i dont want one and the First ai did not work any idea how to fix this?

[@q-dawg1]

How do you make a koopa troopa that retreats into its shell, like in Super Mario Bros. Also, I'm making a mario game and am having trouble making a camera that moves left and right, but not up and down.

[@tailsmilesprower9451]

But how do you do it with floating enemies I thought this video would help me. But I guess not when moving object can't float

[@AllDaBois]

You can technically track the players Y position and create an enemy that will hover above the ground. I’ll do some looking into having enemies that can actually fly around though and see if I can come up with anything

[@smurfy_chicken3938]

Every time my follow steps for the first enemy it doesn't work I know it's not your fault I can't figure out what I'm doing wrong, his kind of driving me nuts, I have a question, can I use your enemy AI logic only, as long as I gave you credit for the enemy Ai logic?

Paces And Follows: Goomba

[@masterfarr8265]

how come when I tried to make the alien move it spins

[@AllDaBois]

Are you using a Spinning/Rotating Object Nodon? Or a Moving Object Nodon?

[@L1N3R1D3R]

I think they meant spinning while moving with the Moving Object Nodon. The Alien has a weird hitbox, and normally its friction will cause it to take a while to start moving and not stay upright once it is moving. The simplest fix is making the Fancy Object Nodon for the alien slippery under Material settings, but that may or may not have unintended consequences. You could instead replace the Moving Object Nodon with an X Slide/Free Slide Connector Nodon connected to an invisible Box Nodon to disable rotation on the object.

How to you make it constantly go in one direction?

[@birdguy9864]

Use constant nodon conected to the desired direction on the character and if it is going the opposite way then link the constant nodon to a inversion nodon then connect that to the direction on the character
