TopDown Engine Tutorial : Advanced AI

[@BadBanana]

This is worth what you charge for the entire package alone mate. Extraordinary machine, i plan to use this on my server

[@_MoreMountains]

Thanks for the kind words!

[@PreRendered]

This is such a classy implementation of the state machine for AI. I've learned SO MUCH from reading your code. I can see all the years of hard work in the polish behind the scenes. Thank you for this asset!

[@_MoreMountains]

Thank you for the kind words, I'm glad you appreciate the craft :)

[@Omhetehmo]

I've just bought this amazing asset and after a few tutorials I feel so powerful and free to just start making a game without all the extra hassle. Much respect!

[@_MoreMountains]

I'm glad you're enjoying it :)

[@merrick20]

It amazes me how good these assets are... good job!

[@_MoreMountains]

Thank you!

[@KoshakiDev]

The implementation of the state machine is genius. So elegant!

[@_MoreMountains]

I'm glad you appreciate the craft!

[@SuperZanlith]

Thank you for explaining. I was really confused before that video!

[@satoshisaito842]

Thank you for this ! It helped me a lot, I'm forever in debt to you !

[@_MoreMountains]

I'm glad it helped!

This is amazingly beautiful

[@_MoreMountains]

Thank you!

[@gthpgth]

It's a beautiful structure.

Hello, is it possible to create "faction" like AI behaviour? Meaning, if the player shoots an NPC then other NPCs of the same "faction" or type also starts shooting on the player? (otherwise they remain standing) Like a "loyalty" system?

[@_MoreMountains]

There's no such feature (it's quite specific), but yes, it's absolutely possible to implement it. I think a new type of AI Decision, that would look at some global "loyalty" reference would work quite well.

[@ausername4meplease]

@@_MoreMountains A true! Thank you. Another thing, I am looking for a way to use "memory" when creating AI for an NPC. Like if the player attacks an NPC and then runs away and returns to the area where the NPC is again the NPC "remembers" the players attack and shoots. The same solution as for factions?

[@_MoreMountains]

@@ausername4meplease Yes, it could be as simple as changing a bool state somewhere, or as complex as you want it to be.

[@TUPGD]

Why is it that some people can get a response or answer but others are sent to the “support form”? Do you not know the answers to your own creation?

[@nicejke9630]

Hi, I'm using your engine and I ran into a little problem. I use AIActionMoveTowardsTarget3D to send bots to attack a stationary player, but only the first one reaches the attack radius, the rest stick into his back. Can I fix this with the tools available in the engine?

[@_MoreMountains]

You'd use a pathfinding action for that, not a simple Move one.

[@nicejke9630]

@@_MoreMountains I'm just an idiot. I did not understand that 2 actions can be linked to one state and I can move and pathfinding at the same time. Ty for reply!

[@_MoreMountains]

@@nicejke9630 Happy to help!

[@nabil6254]

can you tell how to use swap brain? I want to make a boss that has 2 phases. Pleasee, thank you.

[@_MoreMountains]

It's a very simple action, you add it to your brain, bind the new brain you want it to swap to, and you use it in a state.

[@nabil6254]

@@_MoreMountains I create an empty object with an AIBrain Component in it, what else component should i add? I want the brain to perform an attack.

[@_MoreMountains]

@@nabil6254 th evideo you're on, or the corresponding documentation section explains that in details. if you still have questions after checking them and the many examples out, don't hesitate to use the support form.

[@alengazibegovic3485]

does your ai include gridmovement script too?

[@EDW4RD249]

How can you add a melee enemy, that uses the LoftAISword prefab included in the engine? I added it to an enemy but it does not cause any damage to the player (it has the player layer as the target for damage)

[@_MoreMountains]

Please use the support form if you need support.

[@ausername4meplease]

How about AI for none violent encounters? For example if I create a game where their are NPCs walking around in a shop and sometimes pick things up and walk to the checkout and buy the products. Can I do that with this AI?

[@_MoreMountains]

It's an AI system, you can use it for anything you want. If you implement dedicated actions for the stuff you describe, the system will support it.

[@ausername4meplease]

@@_MoreMountains Great to hear! Would be cool to see a tutorial video about how to use the AI in other contexts than combat. Thank you for an excellent library.

[@deveshsingh0904]

It's Amazing work!! Having an experience of past 3years I could definitely say this would really save a dozens of my hour in future run . Just Getting stuck at a problem : How could I use the inventory to the AI character.like I want to create an AI with dufferent Guns but at Initial weapons its only One weapon slot where I couldn't See any update If I put forward another weapon other then sword?? Could you please just Write a format of scripts I need to align to get this gun shooting working??

[@_MoreMountains]

There's already a ChangeWeapon AI action to cover that use case. If you have more questions, please reach out via the support form, thanks.

[@deveshsingh0904]

Thanks Trying it now

[@limoludek]

Is there any way to make ai target character when they get shot?

[@_MoreMountains]

There's the AIDecisionHit you can use for that. See topdown-engine-docs.moremountains.com/advanced-ai.html#decisions

[@jiancui1520]

I didn't check the AI code yet, have a quick question, if i have multiple Bosses, and I want them to have different kind of AI Combat, this Advanced AI supports this or I should extend and build my own. Thanks

[@_MoreMountains]

Sure, that's possible.

[@SuddenlySlanted]

Hello, quick question about this. I've looked at the ninja in the demo and he only has to aim his hitbox left and right. There is no way with a melee weapon to aim the hurtbox up and down. I've tried doing the same thing as you showed in your previous "animations" video (weaponaim2d script set to primary movement) but that doesn't move the hitbox like it does for a player character. I'm curious how this would even work with an AI character.

[@TUPGD]

It won’t. Is why you won’t get a reply about it. A lot of things that don’t work or work how you’d think they would, you won’t get responses for. That’s how they (the creators do) It’s a great system but you won’t be able to make what you really want. You’ll have to make something out of what’s already there.

[@ThePixelitomedia]

Does it have "hearing" and "searching" at the last known position for a radius or time? Can the AI call backup? Will they go into melee when the enemy is too close? Do they have limited ammo and will search for weapons or ammo? Can we set the aim quality of the ai?

[@_MoreMountains]

It's an atomic AI system. It does whatever you tell it to do. If you create an action for the AI to "call backup", it will. I'd recommend watching the tutorial or reading the documentation to get a better understanding of how it works.

[@itsJDarts]

Phenomenal

[@СергейТюльпин-г3п]

hi i bought a top down engine, i can't make an ally AI. help me please

[@_MoreMountains]

Without knowing anything about what you did, that's gonna be hard. I'd recommend checking the documentation (topdown-engine-docs.moremountains.com/advanced-ai.html), it explains all there is to know about the AI system. If your issue persists, please use the support form, not youtube comments, and provide more info about your context, what you did, and what exactly doesn't work.

[@harrison1657]

How do you make 2D enemies use ranged weapons? I've tried to give ninjas a koala rifle, but they can't aim with it. I checked FaceTarget/AimAtTarget and added AIActionAimWeaponAtMovement for Attacking, but none of that worked. Also, thanks for these tutorials they're really helpful!

[@harrison1657]

Nvm, all I had to do was to set Aim Control to Script. But now they're acting weird when you come too close, quickly changing their aim from left to right. Also, they won't shoot at you if you stand still... >_>

[@_MoreMountains]

Please use the support form for support questions, thanks.

[@MagenkyoHellAngeal]

Move away from the target no longer exist as an ai action, why did this happen?

[@_MoreMountains]

Yes, it does still exist. Both in 2D and 3D versions.

[@TheCykid]

is there any 2d Pathfinding?

[@_MoreMountains]

Not at the moment.

[@TheCykid]

@@_MoreMountains okay, thanks for the quick reply, I was able to solve the whole thing with the free version of the asset "A* project", the adjustments that were necessary for this could be implemented well. All in all I am very happy with my purchase :) Thanks for the tutorials as well as the good documentation.

[@_MoreMountains]

@@TheCykid Usint the A* Project for this is absolutely what I recommend, good pick!

[@theplaymakerno1]

I feel like Top Down Engine is Super Bloated.

[@_MoreMountains]

Bloated by what? Everything is built in an atomic way, you don't need to use everything in it, it's a framework. Everything you don't use won't have any impact on anything (build size, performance, etc).

[@theplaymakerno1]

@@_MoreMountains I apologize. I didn't know that the channel belonged to More Mountains, who I believe are the creators.

[@_MoreMountains]

No need to apologize, you're entitled to your opinion, it's fine :) But please don't hesitate to elaborate, "bloated" is a strange criticism to make to a framework built like that one.

[@theplaymakerno1]

@@_MoreMountains it is not a criticism. Most software these days is bloated
