creating vehicles

beefsack · Jun 18, 2003

i searched for vehicle threads and only found one useless to me so i will post anew.

does anyone know where i might find a tutorial on creating vehicles. i havent found a particularly helpful one yet, and have had some troubles creating one from scratch and not having it control really poorly :/ ive been told by someone to not bother subclassing kcar and just subclass kvehicle cos it gives more control but that seems very daunting...

Try Unreal Wiki: Vehicles and Unreal Wiki: Modifying the Bulldog.

heh yeah so i guess it will be a lot of trial and error

how about this then. ive been trying to make it so that the player spawns as a certain vehicle. i managed to do it by spawning the vehicle above the player then using KDriverEnter when the player spawns, but this is messy :/ what i want to do is set the pawn class to the vehicle class that i made, but then it doesnt control like a vehicle should, the chassis only flips around when you move the mouse :/ ive been stuffing around with using bits of KDriverEnter but have had no luck yet. any ideas?

Find the Hoverbike Madness mutator and have a look at the code from that, it may help you out a bit since it automatically spawns the player as one of the hoverbikes that come with the game.

k thanks will do

beefsack · Jun 18, 2003

heh it wasnt a bad idea but it turns out the bikes in hovercraft arent actually vehicles, they are the normal player pawns with physics set to flying and the mesh changed

i might check out unrealspeed or unrealracing

beefsack · Jun 18, 2003

i ended up just figuring it out without unrealspeed, it was rather simple too so i feel a bit of an idiot

if anyone cares how i did it just ask

ok, sorry about the spam, but i got another related question. ive been trying to change the skin of the bulldog in the script. basically, now you can spawn as a bulldog, and now i want to make it so it has a different skin depending on what team you are on. during the RestartPlayer function in the gameinfo class i have made i tried to change aPlayer.Pawn.Skins[0] to the texture i wanted depending on the team and after that did super.RestartPlayer. it did nothing

i assume its cos only meshes have skins or something stupid like that. here is the code anyways.

Code:

class BulldogTest extends xTeamGame;

#exec OBJ LOAD FILE=BulldogTestTex.utx

function RestartPlayer(Controller aPlayer) {
    local Pawn p;
    if (aPlayer.PlayerReplicationInfo.TeamID == 0)
        aPlayer.Pawn.Skins[0] = texture'BulldogTestTex.Skin1';
    else
        aPlayer.Pawn.Skins[0] = texture'BulldogTestTex.Skin2';

    Super.RestartPlayer(aPlayer);

    p = aPlayer.Pawn;
    NewBulldog(aPlayer.Pawn).PostSpawn(aPlayer.Pawn); // This is just the function to get the spawning to work correctly
}

can someone tell me whats wrong?

You are changing the skin of the player that will ocuppy the bulldog, but not the bulldog itself.

You can try:

Code:

function RestartPlayer(Controller aPlayer) {
    local Pawn p;
    if (aPlayer.PlayerReplicationInfo.TeamID == 0)
        aPlayer.Pawn.Skins[0] = texture'BulldogTestTex.Skin1';
    else
        aPlayer.Pawn.Skins[0] = texture'BulldogTestTex.Skin2';

    Super.RestartPlayer(aPlayer);

    p = aPlayer.Pawn;

    [b]if (aPlayer.PlayerReplicationInfo.TeamID == 0)
       NewBulldog(aPlayer.Pawn).Skins[0] = texture'BulldogTestTex.Skin1';
    else
       NewBulldog(aPlayer.Pawn).Skins[0] = texture'BulldogTestTex.Skin2';
[/b]

    NewBulldog(aPlayer.Pawn).PostSpawn(aPlayer.Pawn);
}

But that might not work :|

Soooo...

You can try to do it the DeathBall way

Have a NewBulldog_red and a NewBulldog_blue that both are childs of NewBulldog but have a different skin/model. Then just spawn the correct car depending on wich team you are like:

Code:

    if (aPlayer.PlayerReplicationInfo.TeamID == 0)
       NewBulldog_red(aPlayer.Pawn).PostSpawn(aPlayer.Pawn);
    else
       NewBulldog_blue(aPlayer.Pawn).PostSpawn(aPlayer.Pawn);

Btw, why use TeamID? I always use Team.TeamIndex

Might not matter tho...

beefsack · Jun 19, 2003

i thought they were the same :/ and btw i think its a problem with static meshes using materials instead of skins or something, cos in my gameinfo subclass the pawn class itself is NewBulldog, but i will give it a go anyways

ill wait till tomoz tho, cos i wanna eat+sleep now

just a simple question which might answer my question if your suggestion wont work tomorrow. how to you change the material of a static mesh? if it is skins and rens way will work then pls flame me

and i will implement it tomorrow.

ZappyAd · Jun 19, 2003

I do this for my vehicles and just use Skins[0] = newskin.

The only difference is that I do it from within the vehicle object, not externally. So I have something like:

Code:

myVehicle.SetSkin(newSkin)

and within my vehicle object I have:

Code:

simulated function SetSkin(material newSkin)
{
    skins[0] = newSkin;
}

That might be totally irrelevant but it seems to work...

beefsack · Jun 19, 2003

i ended up using zappyad's way but im not sure if it helped cos it ended up being that i had to call Super.RestartPlayer BEFORE i tried to change the skin

thanks for the help everyone

beefsack · Jun 24, 2003

someone asked me how to do it so i ended up making some sample code. hopefully people will find it useful. ive never done anything like this before and im not sure whether i should put it up on unealwiki or something. im sure their are contributors hangin about in the forum so what do you guys think?

anyways heres the sample

Corran · Jun 24, 2003

Yeah, you could probably put it on the 'Modifying the Bulldog' page, there's some good information there.

jasongw · Jun 24, 2003

Here's a question: How do you modify the physics for a certain character model so that it can fly?

Jason

beefsack · Jun 24, 2003

dont you just set its physics to phys_flying?

edit: gah i had a go at wiki but its really n00bie. hopefully someone will clean it up and make it good

jasongw · Jun 25, 2003

I wish I knew for sure

Would that be done in the UPL file?

Jason

beefsack · Jun 25, 2003

i dont think that you can do it like that

only by writing a mutator or something. i could be wrong tho...

Snowboarding????

Hey i'm looking into the possibility of a snowboarding mod for ut2k3.
I'm wondering if making the board a vehicle with a player model on top is the best way to set things up? Or should the whole snowboarder and board be one vehicle? Or could the boarding be part of the player model with slidding physics set high?

Any ideas would be great... im looking for the best way to make the physics look kinda realistic, while having as much control over the animations of the boarder ie tricks, grabs, slides.

Uscripting is strange everytime someone does a change to a player they seem to change a temporary pawn and then they do a sort of copy of the temporary to the proper object
