LUA Questions

[trepid_jesse]

Not sure if it's changed since this, or if it was just commented out for some other reason, but this shit was shit Patty had in this little ff_dm map so Red players couldn't be conced, but apparently Blue people would remain conced indefinitely, haha.

There's lots of player_onevent shits.

function player_onconc( player_entity, concer_entity )
    -- player_entity is always a player
    local player = CastToPlayer( player_entity )
    local concer = CastToPlayer( concer_entity )

    ConsoleToAll( "Running player_onconc! Player: " .. player:GetName() .. " Concer: " .. concer:GetName() )
    ConsoleToAll( "conc_duration = " .. conc_duration .. " conc_iconduration = " .. conc_iconduration )

    if player:GetTeamId() == Team.kRed then
        return EVENT_DISALLOWED
    end

    conc_duration = -1
    conc_iconduration = -1

    ConsoleToAll( "conc_duration = " .. conc_duration .. " conc_iconduration = " .. conc_iconduration )

    return EVENT_ALLOWED
end

This was some shit Jon was fucking with awhile back for throwin' the ball. Cause it'd be cool to be able to throw a ball based on the player's current shit. So, if you're moving at some speed > X, jumping, and whatever else then you could modify the throw speed and shit. I don't think this worked right though, or at the time wasn't fully implemented on the C++ side of shit.

function base_ball:dropitemcmd( drop_entity )
    if IsPlayer( drop_entity ) then
        -- throw the ball
        local ball = CastToInfoScript( entity )

        local player = CastToPlayer( drop_entity )
        if not player:IsInUse() then
            ball:Drop(BALL_RETURN_TIME, BALL_THROW_SPEED)
            ConsoleToAll( player:GetName() .. " passed the ball!" )
        else
            -- ball:Drop(BALL_RETURN_TIME, BALL_THROW_SPEED * 2)
            -- speed actually seems to be capped or somehtin' on the C++ side, because watch this ball not go fast at * 100...
            ball:Drop(BALL_RETURN_TIME, BALL_THROW_SPEED * 100)
            ConsoleToAll( player:GetName() .. " passed the ball really far!" )
        end
    
        SmartSound( player, "misc.woop", "misc.woop", "misc.woop" )
    
        -- Make it so the player can't touch the ball for 1 second
        -- (so it can't be thrown and not stick to the player)
        self:addnotouch(player:GetId(), 1)
    end
end

I don't even know how current that shit is, cause I just copied it out of some old scripts, so, I don't even know if that shit even still works the same cause the Lua shit was changing a lot awhile back.

My jizz is on it.

[Mulchman MM]

yeah, i had that in ff_dm for easily testing it. the ff_dm map is so awesome that i wanted to return it to its normal awesome self so i removed the testing script. that's why it was removed. that maps so awesome too, i know you love it.

btw, all that shit is still valid ^^ except we'll probably remove the ConsoleToAll as it's mainly for just making sure shit works by printing some info to make sure the script is doing what you want it to do.

[o_imbrifer]

Will ff_dm be released to the public with FF?

[Mulchman MM]

if defrag quits complaining about how tiny the ramps are in the respawn, maybe.

FF script leakage *GASP*

For the few people who won't figure it out: I'm joking.

[o_ginger lord]

Ugh, that looks far too much like C++ for my liking

[Mulchman MM]

Well it's lua syntax and everything combined w/ "objects" and "functions" we've coded and are accessible through luabind. it's really awesome/easy compared to what we were doing.

[o_nezumi]

Ok, that was awesome. Thanks for the example guys.

These scripts are just sections of code in a .txt file or something, right? Like a soundscape or something?

How easy it it to get info between the lua script and an entity in the game? Like if you wanted a door to open if a particular player was going faster than a certain speed (or whatever) could you just call the door by it's name in the script and send it an output?

edit:

If it's code and it doesn't look like C/C++ then something is wrong. Or did you mean you want it to be like the key/value pair deal that all of valve's scripts are?

It's Lua, in a .lua file, and has the same name as your map.

Pretty god damn easy. By the time FF comes out, setting up the gameplay for gameplay modes that we release with FF will be as easy, and literally, just putting trigger_ff_script/info_ff_script entities in your map, giving them the correct names, and there's no other work. That isn't meant as an over simplification. Assuming you just wanna do exactly what some pre-existing gameplay shit does, you just need to give the right entities the right names. You ain't have to fuck around with anything except the name. Name? People with zero coding/scripting experience will be able to setup basic gameplay if they know how to put entities in a map, and give entities names, and keep their dick hard.

Like if you wanted a door to open if a particular player was going faster than a certain speed (or whatever) could you just call the door by it's name in the script and send it an output?

I think the player's speed is exposed, but I can't remember if it's accessible by something easy like player.speed. I remember bothering Patty about this awhile back, so, if he reads this and there's not some easily accessible way to get the player's speed -- there should be.

I got the cooooooooooobra.

[Mulchman MM]

You can get the player's velocity so you could do something like...

-- Lua
function my_door:allowed( allowed_entity )
     if IsPlayer( allowed_entity ) then
          local player = CastToPlayer( allowed_entity )
          local speed = player:GetVelocity()

          if speed:LengthSqr() > 200 then
               -- Put the OpenDoor in the ontouch instead
               OpenDoor( self.name )
               return EVENT_ALLOWED
          end
     end

     return EVENT_DISALLOWED
end

The EVENT_ALLOWED / EVENT_DISALLOWED is just true / false but set up kind of like an alias for readability.

And actually, the better way to do it would be to remove the OpenDoor line from the allowed function and put it in ontouch() like so:

-- Lua
function my_door:ontouch( touch_entity )
    OpenDoor( self.name )
end

Right now when you touch a trigger_ff_script the allowed function is called and if it (allowed()) returns true then ontouch is called. If it (allowed()) returns false then onfailtouch is called. (so hopefully you see where I'm going with this and can follow what I'm saying!)

[o_industrial]

Did you guys make it OO, or is that just fancy metatable work? (player, speed objects. Not sure about the door one :P)

I know of a World of Warcraft addon project (wow uses lua for the interface) that has managed to make an OO system with mixins

[Mulchman MM]

Tables and luabind. The base info_ff_scripts & trigger_ff_scripts are all table jizz. Everything else is luabind.

Like...

Vector, QAngle, Player, Team, etc.

[trepid_jesse]

Show me how you suck a guy's cock. Show me with your mouth.

[o_nezumi]

What is the CastToPlayer() function? What's it do?

[o_dancingfool]

With your mouth, shows you how to suck a guy's cock obviously.

[o_sh4x]

Discussions have become more and more interesting in the mapping forum lately.

You use that so you can do the player-specific shit with that entity (only if it's actually a player, though).

Like uh...

function ona_trigger:OnTrigger( trigger_entity )
	if IsPlayer( trigger_entity ) then
		local player = CastToPlayer( trigger_entity )
		if player:HasItem("ona_party_rock") then
			BroadCastMessageToPlayer( player, "O&A PARTY ROCK!" )
		end
	end
end

Those HasItem and BroadCastMessageToPlayer functions wouldn't work if you didn't make "player" an actual player.

There's also a CastToInfoScript so you can do things like call Return() to send an item/flag/script entity back to its origin.

[o_nezumi]

So, something like

if trigger_entity:HasItem("ona_party_rock") then

doesn't work?

[Mulchman MM]

Eh, what is trigger_entity?
