Example:


// Bot module.
require( "bot" );
//require( "botx" );

// create our bot.
local controller, entity 	= bot.Create( "MingeBag 2.0" );
//local buttons			= botx.CreateButtonsHelper();
local viewangle 		= Angle( 0, 0, 0 );
local aim_at_player		= true;

// just make it walk forward.
local function botThink( )
	// no bot?
	if( !entity:IsValid() ) then return; end

	// aim at nearest player.
	if( aim_at_player ) then
		// closest dist.
		local closest, dist = nil, 8192;
		local list, pl = player.GetAll();
		for _, pl in pairs( list ) do
			// closer?
			local length = ( pl:GetPos() - entity:GetPos() ):Length();
			if( pl != entity && length < dist ) then
				dist = length;
				closest = pl;
			
			end
		
		end
		
		// found?
		if( closest ) then
			// aim.
			viewangle = ( closest:GetShootPos() - entity:GetShootPos() ):Normalize():Angle();

		end
	
	
	// increment angle.
	else
		viewangle.y = viewangle.y + 50 * FrameTime();
		if( viewangle.y > 360 ) then viewangle.y = 0; end
		
	end
	
	// set bot angle.
	entity:SetLocalAngles( viewangle );
	
	// walk.
	controller:Run(
		190,					// forward ( walk )
		0,					// side ( strafe )
		0,					// up ( swim, I think )
		viewangle,				// view angles
		0,					// buttons
		0,					// impulse
		0,					// weapon select
		0					// weapon sub type
	);

	//
	controller:PostClientMessagesSent( );
	
end
hook.Add( "Think", "BotThink", botThink );

Great release!

**Termy58** · 13th May 2007

I remember testing it great job!

**zerglingv2** · 13th May 2007

but its no vmf suite :crying: good job

**Megiddo** · 13th May 2007

Nice, I see you used my lua module server plugin method. Glad I could help someone. :D

**Elspin** · 13th May 2007

Jinto, you win all the internet.

I understood about 0% of that. God damn that's hard.

**FPtje** · 13th May 2007

I understood -100% of that :D
oh well...

Bot=bot whee=whee

Jinto made me happy :D

Devenger · 13th May 2007

So we could potentially (laggily) create bot players and give them a basic AI via Lua inputs?

**Conna** · 13th May 2007

Fantastic Jinto.

**Jinto** · 13th May 2007

I moved the controller functions into the bot controller metatable. Should be easier to use now. Link is in the first post.

bot.SetActiveWeapon( mybot, "weapon_pistol" );

Becomes.

mybot:SetActiveWeapon( "weapon_pistol" );

**InsanePyro** · 13th May 2007

I DEMAND CSS BOTS/NPCs!

**Conna** · 13th May 2007

I lol'd.

**HTF** · 13th May 2007

Nice work, pretty epic.

SteveUK · 13th May 2007

Very cool module, hopefully we'll see some AI around soon.

Hoffa · 13th May 2007

awesome :excited:

The Mathias · 14th May 2007

This is pretty sweet. You can use player functions with them too, right?

Yup.

Suicidal_B · 14th May 2007

Niceness, but i can't get him to shoot? i've set weapon_physcannon and it stopped shooting on default, then i tried

controller:ExecCommand( "+attack; -attack" );

right after controller:Run

what did i do wrong?

The buttons argument of BOTCONTROLLER:Run is a bitmask of all the keys you want them to have held this frame.

// walk.
    controller:Run(
        190,                    // forward ( walk )
        0,          // side ( strafe )
        0,          // up ( swim, I think )
        viewangle,        // view angles
        IN_JUMP + IN_DUCK,          // buttons
        0,          // impulse
        0,          // weapon select
        0               // weapon sub type
    );

**jA_cOp** · 14th May 2007

Awesome, I'll give a try at an AI :D

How do I disable the default bot behaviour?

Also, what does this do

bot.PostClientMessagesSent( controller )

My d/l doesn't say controller in between, but yeah i also have that question (will try keys now, thanks)

Edit: Another thing, the bot often goes in some kind of slomo reverse, it still aims right but walks backward (sometimes forward too) really really slowly, with a slow animation, any fix for that?

**Jinto** · 14th May 2007

Code:

bot_zombie 1

Disable the default gmod bot behaviour. As for the funky animation, I get that too, never found a workaround for it.

Suicidal_B · 14th May 2007

Hmm, the angle it shoots in isn't the same as the angle its looking at, any thoughts? i'm just trying some basic stuff on gm_construct and it keeps shooting towards behind the spawn, no matter what angle.

Then i gave it a physgun and it pointed to same place behind spawnpoint, so if you could be so nice, look into it

Edit: I do find this awesome though, despite my many questions

**CapsAdmin** · 14th May 2007

Wow.

Just read the comments and I'm pretty sure you'll understand it just fine (The green text.)

**smallfry** · 14th May 2007

Can they use .nav files?

**earthHunter** · 14th May 2007

This is great. I can't wait to try it out with CapsAdmin.

If you programmed them to.

**morpheous** · 14th May 2007

Thought I'd let you know...

Fantastic module; eagerly awaiting the first scripts using this.

Suicidal_B · 14th May 2007

I'm working on a basic friendly bot (as in not meant to deathmatch)
When it finds a prop near it runs to it and stops before hitting it, then tries to punt it away using the physcannon (yellow gravgun), though that keeps failing (i'm thinking its looking over the prop or something, the bot doesn't seem to aim up/down)
Either way it's great fun, thanks loads

**jA_cOp** · 15th May 2007

Bot.Controller:Run( 0, 0, 0, Bot.Entity.Master:GetPos() - Bot.Entity:GetPos():Angle() , IN_FORWARD, 0, 0, 0 )

That's run every frame - and is supposed to make it follow its creator. However, when I start the think hook that runs it gmod crashes.

Any idea why?

Suicidal_B · 15th May 2007

Why are you using Bot.Entity, use entity or controller (entity in his case i guess)

Edit: you also didn't normalize the angle

viewangle = ( ply:GetPos() - entity:GetShootPos() ):Normalize():Angle();

Thanks, but the error was actually I was missing some parens :)
There is no need to normalize it either. And bot.Entity is a variable by me :)

**BulletofHell** · 15th May 2007

Uh. I can't get this to work, I may be doing something wrong, I put this in the console:

Code:

 bot.Create [MingeBag]
Or bot.Create( [MingeBag] )

Halp pl0x?

It says it's an unknown command.

Sieni.us · 15th May 2007

What compiler you did use to make this?

I want to learn C++ but i need good compiler & need to learn use it before learning C++.

This is a lua module, you can't use it with the console.

thanks !

Garrysmod/Garrysmod. Now can someone answer my question?

You don't. This module adds lua commands for scripters to use. If you want to try the example script though - type

Code:

lua_openscript bot.lua

in the console.

If you want bot scripts, just wait for a release using this :)
