Looking for a video tutorial on vehicles

[Mega_Mad_Maxx]

Yesterday:
Here is what I want to do, make the main cannon fire regular, but have the machine gun be on the Alt fire.

Next day: Problem solved
It is such a good feeling to figure out how to acomplish a goal on your own
by having just a little bit of an understanding how things are linked when you see other code.

After looking at the Hammerhead code I figured out how to do it and decided to share my findings.




Here is the code for H2_Wraith_Chassis.uc

//-----------------------------------------------------------
//
//-----------------------------------------------------------
class H2_Wraith_Chassis extends ONSHoverCraft;



//// Switch weapons when alt-fire is pressed and display a message.
function AltFire(optional float F)
{
    if(IsFiring())
        return;

    if(ActiveWeapon == 0)
    {
        if(PlayerController(Controller) != None)
            PlayerController(Controller).ReceiveLocalizedMessage(class'H2_Wraith_Message', 1);

        SetActiveWeapon(1);
    }
    else
    {
        if(PlayerController(Controller) != None)
            PlayerController(Controller).ReceiveLocalizedMessage(class'H2_Wraith_Message', 0);

        SetActiveWeapon(0);
    }
}
//Switch back to main gun when driver leaves.
function UnPossessed()
{
    Super.UnPossessed();

    SetActiveWeapon(0);
}

HI guys just a quick question: anyone have an idea where from exactly is the function "ClientSetViewTarget"/"SetViewTarget"/"BecomeViewTarget" called from? Looking for the one responsible for switching the Eye position to another Pawn/Vehicle)
Is it called from KDriverEntered, or PossessedBy, or from somewhere else, possibly native?
This is the function that tells the player to switch it's 'camera' to the vehicle itself.
Thx in advance!

[meowcatbuf]

From what it looks like ClientSetViewTarget calls come from other functions in the PlayerController.uc class.

From what I can tell, the 'KDriverEnter' function in the Vehicle.uc class calls 'C.Possess(self)' on the controller to take charge of the vehicle. Possess (in the PlayerController.uc version) assign the pawn (vehicle in this case) to the controller, then calls the function 'Restart()'. This function then calls 'SetViewTarget()' and also the 'ClientRestart()' function which is replicated down to the Client's version of the controller.

Hey meowcat,

For the longest time I have wanted to fire a blue plasma arch (if you know what I mean) from my wraith tank.
Some one told me a long time ago that the HaloUT team made a H1 wraith tank, but I cant find it anywhere.
I have looked high and low and cant find a mod that does this or something similar.
The closest thing I found is that standard ut2004 green blob gun. It does fire the blobs in an arch, so I think it is possible.
I just need to find out how to change its property's (I think) from blob to energy and make it bigger and fire slower.

So, do you have any ideas how this can be done?

I am having trouble with a custom vehicle of mine, the problem is that when I try to steer, the vehicle just stops dead and even starts moving sideways a bit. I tried increasing the output values for MaxSteerAngleCurve, and also reducing the turn damping but I am still not able to fix it.
My values are:

MaxSteerAngleCurve=(Points=((OutVal=1000.000000),(InVal=300.000000,OutVal=850.000000),(InVal=500.000000,OutVal=700.000000),(InVal=600.000000,OutVal=600.000000),(InVal=1000000000.000000,OutVal=500.000000)))

ut2004isdead/Max: Most of that arc-projectile effect will be in the projectile class and its effect and explosion effect class. I recommend starting with the ONSPlasmaProjectile as a base class, or maybe just subclass it. It already has similar particle effects already. To get the arcing effect, you will then need to change its Physics mode, either in the default properties or via a 'timer' call sometime after it spawns, to PHYS_Falling. You will have to learn about emitters and experiment a bit to get an effect that you like. I usually just copy and paste and Emitter effect that I like from something else into a new class, then edit it as necessary until I get something I like.

Here is a simple subclass to start from:

class WraithProjectile extends ONSPlasmaProjectile;

defaultproperties
{
    ExplosionDecal=class'LinkBoltScorch'
    HitEffectClass=class'Onslaught.ONSPlasmaHitGreen' // <- maybe make a subclass of this, then scale everything larger
   PlasmaEffectClass=class'Onslaught.ONSBluePlasmaFireEffect'  
    Lifespan=5.0 //1.2
    Speed=7000
    MaxSpeed=7000
    AccelerationMagnitude=0.0
    Damage=95 //70
    DamageRadius=350 // 240.0
    MomentumTransfer=4000
    Physics=PHYS_falling // Physics=PHYS_Projectile // <- changed this to have it drop
    DrawType=DT_None
    Style=STY_Additive
    AmbientGlow=100
}

@Deggenyr: I think I've seen that before... but I don't quite remember what setting was causing it. You can use 'code' tags by putting the word 'code' in place of the word brackets like this [brackets] code paste goes here [/brackets], to make your default properties paste show up in the forum as a code block (easier to read).

I have a small ATV vehicle in my own mod that works fairly well, here are the default properties for comparison. I've noticed that small karma physics vehicle seem to behave "squirrely", I don't know if that is just because the forces then applied to them can so easily perturb them or what, just that they seem to get wonky pretty easily. I bumped up the mass of my ATV (to almost half the HellBender's) in a partially successful effort to have be less "bouncy". The other thing to keep track of is where the Vehicle's center of mass is located (it can be adjusted by the Offset in the KarmaParams properties, or by physically shifting the model's center point), and how its collision boxes and wheel traces are interacting, good debug commands can be found here, and here is the old psyonix svehicle tutorial (highly recommend downloading offline copies of these webpages, and any of these UDN2 ones.... they probably won't be around for much longer considering they are already 14+ years old).

I am having a problem getting my vehicles into a total conversion mod.
The TC mod is in a folder called Halo_1, I was able to run my custom maps from the Halo_1 folder
but when I try to compile my vehicles in that folder I get this error.

Init: Base directory: C:\UT2004\System\

Heading: ------------------------H1_Vehicles - Release-------------------------
Warning: Failed to load 'H1_Vehicles.u': Can't find file 'H1_Vehicles.u'
Warning: Failed loading package: Can't find file 'H1_Vehicles.u'
Log: Analyzing...
Critical: Can't find files matching H1_Vehicles\Classes\*.uc
Exit: Executing UObject::StaticShutdownAfterError
Critical: UMakeCommandlet::Main
Exit: Exiting.

Do I need to put all files in one folder to compile or do something different?

[meowcatbuf]

Hi Maxx, I had my mod running in its own folder using UT2K4's mod system at one time, but I don't know if I ever actually compiled anything in that folder. I think I compiled the .u files normally in the UT200/System directory and then just moved them to the other folder afterwards. I think you can specify extra folder paths in the .ini file so that the compiler can check other folders... but its been over ten years since I tired that.

These two old links over at the UDN2 may help
PublicModResource
Improved Mod Support

[Mega_Mad_Maxx]

The link you gave me fixed the problem.
Now I have vehicles in my mod.

I changed the folder paths on the MyMod.ini inside of the MyMod folder.

Paths=../MyMod/Animations/*.ukx
Paths=../MyMod/Help/*.ukx
Paths=../MyMod/Maps/*.ut2
Paths=../MyMod/Music/*.umx
Paths=../MyMod/Sounds/*.uax
Paths=../MyMod/StaticMeshes/*.uax
Paths=../MyMod/System/*.u
Paths=../MyMod/Textures/*.utx

Then I made a shortcut to UnrealEd and in the properties/target I add this command line
C:\UT2004\System\unrealed.exe -mod=MyMod

Then I was able to add vehicles to my mod maps.

Thanks meowcatbuf

------------------------
One other thing:

In the "UDN - Two - ImprovedModSupport" link under the script packages section,
it mentions the MyModGUI but it does not tell you how you create one.
Is there a way to copy the ut2004 menu/gui code and textures so I can create a custom menu/gui in the MyMod folder?

[meowcatbuf]

Yeah, there was a way to do that (a bunch of the TC mods had their own really slick looking menus), but I don't quite recall how. You usually ended up having to edit all of the little GUI textures yourself (to make them your preferred color as I recall), but the I think it was just a couple of classes.

When I'd worked on my own TC mod, I used a simple "base mod" that someone had put together for other to use and build on, I recall it being pretty straight forward to setup. I'll see if I can find the zip file.

[Mega_Mad_Maxx]

a bunch of the TC mods had their own really slick looking menus

I know what you mean, a TC mod called "The Soul Keeper" has a 3d animated background. I would love to know how to do that.
But for now I would be happy with just a copy of the ut2004 menu running on my mod (with a different background image of course)
