[WIP] Lua Weaponwerks (Now with video!)

[Marleys Ghost]

This is all looking very good indeed TylerH.

[TylerH]

I have a nice update for everyone.

 

I was able to convert everything over to the class-based system nicely. Here is a newer draft-draft pre-alpha weapon.lua script with all the functionality I want currently except Secondary Fire mode, Melee attack, and the handling of automatic fire:

 

Here is the gold_xix.lua first, so you can see how relatively easy it is (this is all you have to do for your gun setup-wise):

dofile("scripts/classes/weapon.lua")

GoldXIX = { }


GoldXIX_WeaponTable = {
ViewModel = "abstract::HUD.gmf",
Offset = Vec3(0.0,-0.005,0.05),
Scale = Vec3(0.04,0.04,0.04)
}

GoldXIX = CreateWeapon(GoldXIX_WeaponTable)

-- Properties
GoldXIX.Primary.Delay = 400

-- Animations
GoldXIX:AddAnimation("WEAPON_IDLE", 277.0, 302.0, 1.0)
GoldXIX:AddAnimation("WEAPON_ZOOM_IDLE", 212.0, 238.0, 1.0)
GoldXIX:AddAnimation("WEAPON_EMPTY_IDLE", 779.0, 804.0, 1.0)

GoldXIX:AddAnimation("WEAPON_MOVE", 304.0, 326.0, 2.0)
GoldXIX:AddAnimation("WEAPON_ZOOM_MOVE", 239.0, 261.0, 2.0)
GoldXIX:AddAnimation("WEAPON_EMPTY_MOVE", 805.0, 829.0, 2.0)

GoldXIX:AddAnimation("WEAPON_TO_ZOOM", 180.0, 187.0, 2.0, true)
GoldXIX:AddAnimation("WEAPON_FROM_ZOOM", 188.0, 194.0, 2.0, true)

GoldXIX:AddAnimation("WEAPON_FIRE", 62.0, 74.0, 3.0, true)
GoldXIX:AddAnimation("WEAPON_ZOOM_FIRE", 262.0, 274.0, 3.0, true)

GoldXIX:AddAnimation("WEAPON_FULL_RELOAD", 82.0, 150.0, 3.0, true)
GoldXIX:AddAnimation("WEAPON_TACTICAL_RELOAD", 640.0, 690.0, 3.0, true)
GoldXIX:AddAnimation("WEAPON_MINIMAL_RELOAD", 581.0, 639.0, 3.0, true)

GoldXIX:AddAnimation("WEAPON_TAKE_OUT", 50.0, 58.0, 1.0, true)
GoldXIX:AddAnimation("WEAPON_PUT_AWAY", 152.0, 159.0, 1.0, true)

-- Initial Animation
GoldXIX:SetState(WEAPON_IDLE)

-- Sounds
GoldXIX:AddSound("Fire", "abstract::fire.ogg", 65)
GoldXIX:AddSound("ZoomFire", "abstract::fire.ogg", 265)
GoldXIX:AddSound("EmptyFire", "abstract::fire.ogg", 697)
GoldXIX:AddSound("WEAPON_DRYFIRE", "abstract::dryfire.ogg", 0)
GoldXIX:AddSound("FullReload", "abstract::reload.ogg", 85)
GoldXIX:AddSound("TacticalReload", "abstract::reload.ogg", 644)
GoldXIX:AddSound("MinimalReload", "abstract::reload.ogg", 585)
GoldXIX:AddSound("FullCock1", "abstract::cock2.ogg", 135)
GoldXIX:AddSound("FullCock2", "abstract::cock2.ogg", 143)
GoldXIX:AddSound("MinimalCock", "abstract::cock2.ogg", 629)

 

And here are the snippets for all that you have to call in your render loop (this will be abstracted into its own little thing and use a simple WeaponSystem:Update() or something to check all weapons in the table):

GoldXIX:Update()

if (KeyHit(KEY_W)-KeyHit(KEY_S) ~= 0 or KeyHit(KEY_A)-KeyHit(KEY_D) ~= 0 and GoldXIX:GetState() == WEAPON_IDLE) then
	GoldXIX.Moving = true
end
if (KeyDown(KEY_W)-KeyDown(KEY_S) == 0 and KeyDown(KEY_A)-KeyDown(KEY_D) == 0 and GoldXIX:GetState() == WEAPON_MOVE) then
	GoldXIX.Moving = false
end
if (MouseHit(2) == 1) then
	GoldXIX:ToggleIronsights()
end
if (KeyHit(KEY_1) == 1) then
	GoldXIX:Toggle()
end
if KeyHit(KEY_R)==1 then
	GoldXIX:Reload() 
end
if MouseHit(1)==1 then
	GoldXIX:PrimaryFire()
end

 

The library is pretty robust for the 546 lines that comprise the weapon.lua, and 231 lines in bullet.lua. They will both receive their upgrades as I start working my way through the rest of the feature tree, starting with the core stuff, and working towards eye candy and fun stuff (like akimbo and laz0rs ).

 

Note that the commandset called in the game-loop is really that easy. The weapon's finite state logic and update loops will handle itself efficiently and properly, and has built in checks for commonly missed things like firing while reloading, etc. though bugs may exist and it will be improved. With permission I will either put a section with an API for this on the Wiki, or in its own thread.

Questions? Comments? Concerns? etc.?

 

A demo will be out soon, think within the week-ish. Another video will precede the demo.

[TylerH]

For anyone curious about the current setup:

CreateWeapon takes a table that needs to have a .ViewModel string, .Offset vec3, and .Scale vec3.

 

AddAnimation takes a unique name (the ones you see there are what the internal system will be looking for, though I may add the ability to set them custom soon). The second and third parameters are start and end frames. The 4th is a speed modifier, and the last is an optional "one shot" boolean. Things like idle and move are looped, so it defaults to false, but things like reload and fire are done once per state before the state changes.

 

AddSound takes a unique name (the system is designed to play them by frame, but I added WEAPON_DRYFIRE in at the last second along with a weapon:PlaySound(name) command for custom effects not linked to animation), the sound file string location (it handles creating the sound and source), and the frame of animation it should be played at.

 

I basically tried to take the FPS Creator form of setting up guns via their gunspec.txt files, and implement it in a Lua fashion, though my system offers more customization and can be expanded by the user.

[AggrorJorn]

This is looking very good Tyler. Have you considered overheating? (heavy machine guns)

[TylerH]

No, I hadn't. I will work that into the condition system.

[TylerH]

I have successfully implemented hierarchical bullet ricochet, skimming, and skewing.

 

Right now, the system will use this little bit of code:

-- Process ricochets if they should still occur
			if (bullet.ricochetcount < 3) then

				local I = bullet.velocity--Subtract3(pick.position,bullet.origin)
				local N = pick.normal--:Normalize()

				local angle = 180 - math.deg(math.acos(Dot3(I,N)/(I:Length()*N:Length())))

				if (angle < (60)) then return end

				local R = Subtract3(I,N:Scale(2 * Dot3(I,N)))--:Scale(bullet.velocity:Length()*HOST_TIMESCALE)

				local ricochet = CreateBullet(pick.position, R, Vec3(0.0,0.0,0.0), ricochets)
				ricochet.ricochetcount = bullet.ricochetcount + 1
			end

 

Which grabs the bullet velocity (our incident vector), the normal of the surface we hit (the normal), calculates the angle between these two (which will be obtuse, so we subtract from 180 to get an acute angle that is easier to run comparisons on relative the bullet and player).

 

Presently it is hardcoded to ignore impacts for ricochet if the incident angle is less than 60 degrees. To explain, when you think of a protractor, where the far right flat line is 0, as you move up towards the top is goes from 0 to 90 , this is backwards of how the system works. The Normal is 0 degrees, and as the bullet angle towards the impact point gets close to parallel with the surface that the normal is from, it gets closer to 90. It is checking to see the angle between the normal plane of the object you hit, and the bullet velocity.

 

This has worked and given realistic results (minus that I didn't add friction, velocity fall off, etc. physical effects), and appears to be how this would work in real life.

 

The next thing I want to work on is bullet penetration through surfaces, but I am not entirely sure how this is done, and wouldn't mind some suggestions or ideas on how to do this.

[Niosop]

Your almost making me want to make an FPS Excellent work, it keeps getting better.

[TylerH]

It was fun to remove the ricochet count and angle checks, and just have 12 bullets flying around making ricochets forever. With 12 on screen, I got about 30 FPS, down from 60 FPS, which is believable, for the amount of math I am doing per bullet.

 

Needless to say, I already know about 5 ways to optimize what I have currently, I already made a few changes and gained loads of frames I didn't know had ever been lost

[TylerH]

Yep, I was able to push that up to 120 bullets on screen, running bullet logic, keeping 60 FPS.

 

I also made the gun shoot a non-tracer bullet by default, and will be implementing some logic for either every n^th bullet being a tracer, or a tracer is fired to let you know you have n bullets remaining (i.e. either every 4 rounds, or say when you have 5 rounds left in the current clip).

 

I also implemented colored tracers, so if you want crazy looking tracers, they will be as easy as setting weapon.TracerColor

[TylerH]

This is on hold for a number of bugs in 2.3 single state:

1) Half of the sounds no longer play at the proper frame / at all

2) Animations are running as if the FPS is 5, when the FPS is 60 to 80.

 

Not sure what is causing this.

[niv3k]

dude amazing stuff.

 

can i pay you one day to help me out?

 

If you could code something like the "S.M.A.R.T." from Brink by SplashDamage/Bethesda then you'd be my hero forever, and ever.

 

 

[TylerH]

Possibly, I assume I have you on Windows Messenger already?

[niv3k]

Possibly, I assume I have you on Windows Messenger already?

 

yeah.

[TylerH]

Just to let everyone know I am BACK to working on this wonderful little project.

 

I found that the bugs were infact that issue with the editor and AppSpeed starting to become a little messed up after a while (seems like after opening and closing Leadwerks Editor or Leadwerks-based app 25 or so times it occurs), but a simple restart or even log off and re-logon fixes it, so I can continue bug free where I left off: Bullet Penetration.

 

I had also kind of been tied up experimenting and porting some stuff to UDK for a new project experiment, and it was taking up a bit of time.

 

Cheers,

Tyler

[TylerH]

For real back on working on this. No joke this time.

[VeTaL]

How is your project?

[dennis]

is it still in development?

[Dan_Incognito]

This looks amazing! Hope it's still in development

[Road Kill Kenny]

Its been almost 2 years since the creator of this posted an update so I wouldn't hold your breath if I were you.

[TylerH]

Maybe once my summer break in college hits I'll be back on my programming grind.

[dennis]

When is that ? we want too know :W

[TylerH]

Well I'll have spring break here starting March 19th, gives me 2 weeks to get my antiquated code and apps installed on the new computer. Summer break is the end of May.

[Guest Red Ocktober]

arrrgggh ... those darned real world obligations always getting in the way...

 

--Mike

[dennis]

Indeed, I just graduaded from military school, do I need to get rid of those ?

[DigitalHax]

Be really interested in using something like this in my game in progress... Any chance of a release soon? Or at least a demo?
