Creating Custom AI Question

[[Talanar]]

Please can someone post the missing code? I'm just trying to crack the AI writing and from the posts I see all my questions are answered here (but i cannot understand them without the reference code).
Otherwise I will just have to ask all the questions that has been answered before all over again ://

If you cannot (or you do not want to) share xnasorcerer code, maybe someone will be able to answer the most important thing for me:

1. What is the proper place for a state of patroling (state should be in inside the npcAIController? or NpcPawn?)
2. How can I gather Path Nodes from level (placed in the world, not spawned by script) and point specific NpcPawn to follow them while in specific state (the one from point 1)
3. How can I ask my NPCPawn to play a certain animation from his anim tree (im using the standard base male animset / animtree from UDK)

Thanks in advance, if by chance anyone would want to help me I promise after I'm done I'll write a good tutorial for future noobies like me :]

[Fezan]

ok so no xnasorcerer script and no tutorials where to go

1.the aicontroller is the only place for that.
2. you could try a foreach loop of AllActors of the pathnode class.
3. not sure, but probably PlayAnimation() if that can be accessed.

[LucasWalter]

I apologize for this but where is the AI code from XNASorcerer located at? I have no luck finding it at all...

[KingCobra]

Yea, if any has XNAsorcerer's code that'd probably be really useful for people who have found this thread via search and are still having trouble...

[crunx]

I too am looking for something extremely similar to this. I want to have a bot that randomly patrols using navmesh and then goes to path nodes once he sees the player.

[LucasWalter]

Is the code to this still online, if so could someone point me to it?

[Gmax5]

Not sure why xnasorcerer deleted all of his posts, but luckily I found this.

Wow thank you so much for this!!!

No problem. You could also try Mougli's Tutorials for the Sandbox AI.

Thats a great find, but I'm having a slight problem with one line at the moment,

AnimTreeTemplate=AnimTree'SandboxContent.Animations.AT_CH_Human'

I can see its refering to Mougli's custom content (which I don't have) and I'm wishing to change the "SandboxContent" to something default in the UDK, everything else I changed to default UDK.

Find the WPawnSkeletalMeshComponent in UTPawn, it has the "default" AnimTree assigned.

I've been playing around with XNAsorcerer's code and I've come into a little bit of a snag, the bot is invisible. It doe's move around and does the "I can see you" and "!! IDLE !!" and the collsion box does work.

I suspect I've done something rather stupid thats easy to spot by someone who has more experience then I

[Spoof]

If you're overriding the existing skeletal mesh component, then remove "class=SkeletalMeshComponent" from the Begin Object declaration.

If its a separate component, then add "Components.Add(WPawnSkeletalMeshComponent)" after the End Object closing statement.

Though for that to work correctly you'd need to rename the new component, so I suspect it's the first option. I'd have thought the compiler would catch that error.

[Cassiden]

Huzzah the "Components.Add(WPawnSkeletalMeshComponent)" line worked the bot now walks along path nodes I've told to walk along and spots and follows the player. Now just to get it so the player can shoot it and shoot back.
Update: I've got the bot now being able to be hit, killed and drop the shock rifle. Now I just need to get it so the gun is in the bots hands and use the gun.

I've been trying to get the bots to use the UT weapons, but to no success. This is the AI controller that I'm currently using:

I've added the following to the bot.uc

This is allowing me choose what weapon the bot has in the same way you can with a weapon locker, but I'm not 100% sure if it works or not until I can get the bots to use guns and shoot the player with said gun.

I've spent the last 3-ish days trying the get BotAI script to carry and use a gun against the player,
