Complete Working Weapon Example

Complete Working Weapon Example:

Step 1.

Edit shapeImage.cc line 254

Change from:

dSprintf(fullName,sizeof(fullName),"shapes/%s",shapeName);

to:

dSprintf(fullName,sizeof(fullName),"%s",shapeName);

Compile a new Test Application

Step 2.
Edit PlayGui.gui

add: 
new GuiBitmapCtrl(reticleHud) { 
	profile = "GuiButtonProfile"; 
	horizSizing = "center"; 
	vertSizing = "center"; 
	position = "192 112"; 
	extent = "32 32"; 
	minExtent = "2 2"; 
	visible = "1"; 
	setFirstResponder = "0"; 
	modal = "1"; 
	helpTag = "0"; 
	wrap = "0"; 
	fillColor = "0.250000 0.250000 0.250000 0.250000"; 
	frameColor = "0.000000 1.000000 0.000000 1.000000"; 
	opacity = "0.5"; 
	bitmap = "data/textures/crosshair.png"; 
	autoCenter = "1"; 
	autoResize = "1"; 
};

before the last }; in the file.

create a crosshair.png file, create the textures folder in the data directory and place the image there.

Step 3.

Edit Player.cs

replace the Armor::damageObject function with this one:

function Armor::damageObject(%data, %targetObject, %sourceObject, %position, %amount, %damageType, %momVec)
{
   if (%targetObject.getState() $= "Dead")
      return;

   %targetClient = %targetObject.getControllingClient();
   %sourceClient = %sourceObject ? %sourceObject.getControllingClient() : 0;

   %flash = %targetObject.getDamageFlash() + (%amount * 2);
   if (%flash > 0.75)
      %flash = 0.75;

   %targetObject.setDamageFlash(%flash);
   %targetObject.applyDamage(%amount);
   %targetClient.onClientDamaged(%sourceClient, %damageType, %sourceObject);

   //now call the "onKilled" function if the client was... you know...
   if (%targetObject.getState() $= "Dead")
   {
      // Disable movement temporarly.
      %targetObject.disableMove(true);
      // If we were killed, max out the flash
      %targetObject.setDamageFlash(0.75);
      // Call the death handler.
      %targetClient.onClientKilled(%sourceClient, %damageType, %sourceObject, %damLoc);
      // Play the death animation.
      playDeathAnimation(%targetObject, %damLoc, %damageType);
      // Schedule the respawn.
      schedule(6000,0,"spawnPlayer",%targetClient);
   }
   else
      if (%amount > 0.1)
         %targetObject.playPain();
}

Step 4.
Download this simple weapon MOD Weapon Mod


This is currently a 1 shot kill up to a range of 400 meters. Unlimited Ammo, and no special FX.

um yeah. i couldn't get it to work. whenever i do commandtoserver('addweapon'); , commandtoserver('addrifle'); , commandtoserver('createdummy'); all of those get errors. Now the only thing i cna think of is that i put thim in the wrong directory. i put the weapons files in c:\garagegames\v12\example\weapons. Is this where it's supposed to be?

is there a way to figure out how far away the player you hit is? getRange or something like that?

i want to vary the damage amount by figuring how close to the player you are

if(%scanTarg && !(%scanTarg.getType() & $TypeMasks::InteriorObjectType))
{ 

// Distance to Target

    %clPos = %client.player.getWorldBoxCenter();
    %targPos = %scanTarg.player.getWorldBoxCenter();
    %distance = VectorDist(%clPos, %targPos);


// a target in range was found 
%target = firstWord(%scanTarg); 
   %target.getDataBlock().damageObject(%target, %obj, VectorAdd(%target.getPosition(),%vec), 50, $DamageType::Ground);

// Do damage functions here 

}

I haven't tested it yet... but that should be the basic idea.

Hey I went through this tutorial to get an idea of how to do weapons, its great very insightful. But for me I have to be like right on top of the dummy player to kill him, and even then I have to like fire 2 or three times to kill him, I thought it was a one shot one kill type thing. Anyone else having this??? or am I the only retard in the group. ;)

Our group has had mucho probs with the Max2Dts Exporter. Whenever we've tried to export a model (following relevant tutorials aswell), Max ends up causing an error and crashing. We're all running 3dsmax 3.1, and our coder has tried recompiling with no luck.

Is anyone else having this problem, and can anyone suggest anything?

thanks, it was the ; I was missing :)

but it still doesn't quite work, I can add a weapon, and that drops in, but I get an error message in my console.

server/weapons/scripts/weapons.cs (0): preload failed for RifleImage: Unable to load shape ~/weapons/shapes/weapon_thumper.dts.


--scripts/weapons.cs--

datablock ItemData(Rifle)
{
className = Weapon;
catagory = "Spawn Items";
// IT LOADS IT HERE
shapeFile = "~/weapons/shapes/weapon_thumper.dts";
image = RifleImage;
mass = 1;
elasticity = 0.2;
friction = 0.6;
pickupRadius = 2;
pickUpName = "a weapon";
emap = true;
};

datablock ShapeBaseImageData(RifleImage)
{
className = WeaponImage;
// BUT IT WON'T LOAD IT HERE :(
shapeFile = "~/weapons/shapes/weapon_thumper.dts";
item = Rifle;
ammo = RifleAmmo;
offset = "0 0 0";
emap = true;

// SNIPPED OUT THE REST OF THE SCRIPT
};

but it's getting the file from the same place? Does anyone know why it loads fine the first time but not the second?? :(


thanks

D'oh!

had to change the line of code in

datablock ShapeBaseImageData(RifleImage)

from
shapeFile = "~/weapons/shapes/weapon_thumper.dts";

to
shapeFile = "server/weapons/shapes/weapon_thumper.dts";

apparently the ~ is some linux convention I don't understand, and it was being resolved to "~" instead of "server" like the first example of shpeFile


fixed now, and weapons work - thanks for your help people!

Sean Vogt - if you haven't figured it out yet, you put the weapons mod directory inside the examples directory, so that it is at the same level as base, data, client, etc.

Then you need to invoke the mod with '-mod weapons' on the command line. No one actually came out and said these things all in one place... It took me forever to piece together ... :-)

OK, after all my pleas (mostly answered, thanks guys !) for help in both the closed and open forums, I finally get a chance to give something back:


How to get the LabRat's weapons mod to load without needing to use the '-mod' command-line switch, and bound to keys:

1. Open example\main.cs
2. Near the top, locate $baseMods = "data;client;server;base"; and change it to $baseMods = "data;client;server;base;weapons"; Save your change.
3. Ensure that the weapons mod directory is in the examples folder, ie. examples\weapons

4. add the following functions and key bindings to examples\client\scripts\default.bind.cs

function spawnDummy(%val)
{
if (%val)
commandToServer('createdummy');
}

function spawnWeapon(%val)
{
if (%val)
commandToServer('addweapon');
}


moveMap.bind(keyboard, d, spawnDummy);
moveMap.bind(keyboard, w, spawnWeapon);



6. launch your game. press d to spawn a dummy and
w to spawn a weapon. Or make up your own bindings. Enjoy !

CERDIP

this is a very informitive thread (showed me afew things) altho i am new to this engine, c++ andvc++ , i am no stranger to c programming,batch files, and mods
i didnt realize what the heck the scripts were for, things are starting to fall into place now
I have a question.

how would i get forward and backward movement on the mouse? i have tried this in default bind cs
moveMap.bind( mouse, button3, moveforward );
moveMap.bind( mouse, button2, movebackward );


doesnt work, is there somthing else i need to do (i have nt received my tribes2 yet so i have no optional reference)

the correct lines for the dummy and weapons binds are:
moveMap.bind( keyboard,shift d, spawnDummy);
moveMap.bind( keyboard,shift w spawnWeapon);

now can all
this be done in the engine and compiled so itsnot a mod?

%damLoc isn't defined.

%damLoc = %targetObject.getDamageLocation(%position);

Stole that from T2 :)

Has anybody been able to get this mod to work, post Release 1.1b (the new cvs tag release)?

I had a go at putting it in the other day, and while the weapon seemed to fire (animations, & shell casings), it didn't actually kill anything. It certainly didn't harm "Bob" the dummybot.

Any help would be appreciated. =]
Thanks,
Craig.
