Hello, Im new both to this forum and scripting for GTA IV, I got interested in scripting when i saw the bodyguard mods, zombie mods, etc

I would love a zombie mod for gta 4 , unfortunately i dont see the existing ones very fun. I have contagium 1.2b but its not very fun for me.

first i would just ask: Where do i learn scripting for gta iv? i got C# but find almost no tutorial for scripting in gta 4, secondly, Is there anybody that has zombie textures available for pedestrians?
also, How do i know what commands i can use for gta 4, where do i found these? I cant open scripthook.dll so what programs or tools do i need?


i got some basics because i was very good in lua language for another game, so i aint that bad

now ill have a look at the forum see what i can learn

If you have the .Net ScriptHook package, have a look at this file:
scripthookdotnet_1.7.1.7beta.zip\scripts\for Developers\TestScriptCS\Scripts\TestScripts.cs
See bottom of this post for examples.

You can download the documentation for .Net ScriptHook here
If you want a specific function that isn't implemented in .Net ScriptHook, you can start looking for a GTA Native that might help you.
You can find the complete Natives listing here.
Also have a look at Scripting.h from the C++ ScriptHook source code (fixed)

We actually work(ed) with LUA in GTA IV through the "A.l.i.c.e." plugin...It's just that C#/VB makes everything that much easier, so that's what I use and recommend.



Examples

First example in .Net ScriptHook's TestScripts.cs, made into a ready-to-run script:

CODE

using System; using System.Windows.Forms; using GTA; namespace TestScriptCS {    // ### get 10000 bucks each time you press M ###    public class BasicKeyExample : Script    {        public BasicKeyExample()        {            // Bind method BasicKeyExample_KeyDown to the KeyDown event            this.KeyDown += new GTA.KeyEventHandler(this.BasicKeyExample_KeyDown);        }        // KeyDown returns the pressed key.        // but there is no need to check it when your script watches only this one key        private void BasicKeyExample_KeyDown(object sender, GTA.KeyEventArgs e)        {            if (e.Key == Keys.M)                Player.Money += 10000;        }    } }

Another simple script:

CODE

using System; using System.Windows.Forms; using GTA; namespace TestScriptCS {    public class BasicExample : Script    {        public BasicExample()        {            this.KeyDown += new GTA.KeyEventHandler(this.BasicExample_KeyDown);        }        private void BasicExample_KeyDown(object sender, GTA.KeyEventArgs e)        {            if (e.Key == Keys.M)                DoSomeStuff();        }        private void DoSomeStuff()        {            Ped pl = Player.Character;            if (pl.isAlive)            {                Game.DisplayText("Hello World!");                Wait(600);                pl.SayAmbientSpeech("Thanks");            }        }    } }

Thank you , this should be helpfull

gonna have some more look at those example scripts, So for example if you wanna make a simple zombie mod, You replace pedestrian models so it looks realistic and change their behavior to the player to hate and thats it?

btw how do you change animations to the pedestrian? like instead of walking they would go drunk or something?

Also have a look at Scripting.h from the C++ ScriptHook source code

It's easier said than done, but it is possible yes, there's even a zombie example in TestScripts.cs

QUOTE (venom330 @ May 10 2011, 22:13)

You can make them use predefined animations, there's also an example for this in TestScripts.cs (spliff smoking), or you could tweak physics for a ped by learning more about the Euphoria functions.
I don't have any experience with this so I have no idea what the possibilities are.

QUOTE (venom330 @ May 10 2011, 22:40)

now where do i find these animations? In pedprops i only find textures and models

Here you can find all the animations
http://www.gtamodding.com/index.php?title=...imations_(GTA4)
The game works with Animation Sets, so you request a set, then play an animation from that set, like so:

CODE

AnimationSet anims = new AnimationSet("amb@smoking_spliff"); AnimationFlags animflags = AnimationFlags.Unknown12 | AnimationFlags.Unknown11 | AnimationFlags.Unknown09; Player.Character.Animation.Play(anims, "create_spliff", 8.0F, animflags); Player.Character.Animation.WaitUntilFinished(anims, "create_spliff"); // Animation as a task: Player.Character.Task.PlayAnimation(anims, "partial_smoke", 8.0F, animflags);

QUOTE (venom330 @ May 10 2011, 22:40)

and how do i edit behavior to make example a normal citizen to a gang member attitude with no fear?

I haven't tested this, since I never tried to alter a ped's relation to another group, but this might just work.
Question to others: Is this the best way to enumerate an enum? Thnx

CODE

// Get a close ped Ped p = World.GetClosestPed(Player.Character.Position, 15f); // Ped belongs to Gang_Biker1 group p.RelationshipGroup = RelationshipGroup.Gang_Biker1; // Ped's relation to Gang_Biker1 is Companion p.ChangeRelationship(RelationshipGroup.Gang_Biker1, Relationship.Companion); // Make the ped HATE everybody except his companions foreach (RelationshipGroup group in Enum.GetValues(typeof(RelationshipGroup))) {    if (group == RelationshipGroup.Gang_Biker1)        continue;    p.ChangeRelationship(group, Relationship.Hate); }

After test: This works! It's quite funny actually
There isn't anything in this code to make the ped fearless, but they do start to attack everybody because of the hate relation.
You could just leave out the RelationshipGroup.Gang_Biker1 all together and make them hate everybody, even their own group.

QUOTE

// Make the ped HATE everybody foreach (RelationshipGroup group in Enum.GetValues(typeof(RelationshipGroup))) { p.ChangeRelationship(group, Relationship.Hate); }

(yay for syntax highlighting!)

QUOTE (venom330 @ May 10 2011, 22:40)

There's a Native SET_PED_IS_DRUNK, I don't know if it will do anything.
After test: Doesn't work...
This doesn't replace their animations like you are saying, if that's what you want, you just give them a new animation to perform, as explained above.

[venom330]

for walking drunk i guess you need some kinda event, like you said above. But i dont need to replace the animations for the pedestrian i think, like the zombie mod i have contagium script it doesnt replace anything, its just an .asi file which i guess makes an event that all pedestrians who get hit by another group pedestrians do the same animation, in that case, some kinda injure animation.

can you make a quick simple sample of an animation change on event on a pedestrian if you know how to do ?
or is it possible to find in any testscripts? xD



I mean hm, if you get what i mean, A script triggers on start that a specific Pedestrian (group?) has a specific animation and a hate relation to all others, when he or she attacks another group then they get in the same group as the attacker, thats what the script is about, I find it simple, but as a noob at c# i dont have a clue how to put it as a sample, could you do it please?

Then all problems solved, from there i can learn alot and experiment

I'm actually making a zombie mod from scratch now...
Just because it's the most obvious and probably the funniest things you could do in this game.
I haven't looked at any other zombie mods or anything like that except for the example in .Net ScriptHook.

This may become an awesome mod, but atm I can't tell how it'll work out, it could be just zombie or more like "special infected" style (L4D).

[venom330]

nice

hey i tested the testscript with the zombie and it looks awesome, it was exactly what i wanted, the same drunk animation

So im trying to do it exact as the testscript but i dont want to have to press any buttons to activate it, i also want them to keep attacking me, this is my code so far, very simple, just like copy paste, got an error though

CODE

using System; using System.Drawing; using System.Windows.Forms; using GTA; namespace test {            public class TaskSequenceExample : Script {        TaskSequence FleeTask;      public TaskSequenceExample() {         // Add tasks to the TaskSequence         FleeTask = new TaskSequence();         FleeTask.AddTask.FightAgainstHatedTargets();         // Get a close ped         Ped p = World.GetClosestPed(Player.Character.Position, 15f);         p.CurrentRoom = Player.Character.CurrentRoom;         p.Task.PerformSequence(FleeTask);         foreach (RelationshipGroup group in Enum.GetValues(typeof(RelationshipGroup)))         {             p.ChangeRelationship(group, Relationship.Hate);         }         p.CurrentRoom = Player.Character.CurrentRoom;      }   }   // ### Press Z and the ped you are aiming at will start walking towards you like a zombie  ###   public class EuphoriaExample : Script {      Ped Zombie;            public EuphoriaExample() {         Interval = 250;         this.Tick += new EventHandler(this.EuphoriaExample_Tick);      }      private void DoTheZombie() {         if (Exists(Zombie)) {            Zombie.isRagdoll = false;            Zombie = null;            return;         }         Game.DisplayText("ZOMBIES!!!");         Zombie.Euphoria.BodyBalance.Start(-1);      }      private void EuphoriaExample_Tick(object sender, EventArgs e) {         if (!Exists(Zombie)) return;         if (Zombie.isGettingUp) return; // wait until the zombie is standing         if (!Zombie.isRagdoll) Zombie.Euphoria.BodyBalance.Start(-1);         if (!Zombie.Euphoria.BodyBalance.isBalanced) { // get up again when fallen to the ground            Zombie.isRagdoll = false;            return;         }         Zombie.Euphoria.LeanToPosition.Amount = 1.0F;         Zombie.Euphoria.LeanToPosition.ApplyAsForce = true;         Zombie.Euphoria.LeanToPosition.Position = Player.Character.Position;         Zombie.Euphoria.LeanToPosition.Start();      }    } }

[L0uNGeR]

In the TaskSequenceExample class, TaskSequenceExample() is only fired once, you probably don't want this. Also, you didn't check if the closest ped actually exists (after GetClosestPed).
Also, you specify "p.CurrentRoom" twice.

CODE

if (!p.Exists()) return;

And another: FightAgainstHatedTargets() should have at least one argument.


In the EuphoriaExample class, the Ped Zombie is never actually assigned or created, so it can't be used. You can also see that DoTheZombie() is never used from anywhere.

[venom330]

Yea i just found FightAgainstHatedTargets() at the scripthook documentation so i was gonna try it out, dont know what kinda argument i should have lol.

and i cant use Dothezombie? aww.. so ill have to set an animation for the random ped then, But i only find tutorial activating them by pressing a key, isnt there a command that when the ped is spawned and it sees the player or other peds, then it does the drunk animation and attacks?

You can use Dothezombie(), I just told you that you never use it.

You'd have to use Tick

CODE

public class MyTest : Script {    public MyTest()    {        Interval = 1000;        this.Tick += new EventHandler(MyTest_Tick);    }    internal void MyTest_Tick(object sender, EventArgs e)    {        foreach (Ped p in World.GetAllPeds())        {            if (p != null && p != Player.Character && p.Exists() && p.isAlive)            {                // DO STUFF TO PED            }        }    } }

World.GetAllPeds() works best for stuff like this, but it could be slow.
You can always use World.GetPeds() with a reasonable radius if the above is too slow.

Ok i try this

CODE

using System; using System.Drawing; using System.Windows.Forms; using GTA; namespace MyTest {    public class MyTest : Script    {        TaskSequence FleeTask;        public MyTest()        {            // Add tasks to the TaskSequence            FleeTask = new TaskSequence();            FleeTask.AddTask.FightAgainstHatedTargets(3, 5);            FleeTask.AddTask.FightAgainst(Player);            {                Interval = 1000;                this.Tick += new EventHandler(MyTest_Tick);            }        }        internal void MyTest_Tick(object sender, EventArgs e)        {            {                foreach (RelationshipGroup group in Enum.GetValues(typeof(RelationshipGroup)))            {                foreach (Ped p in World.GetAllPeds())                {                    if (p != null && p != Player.Character && p.Exists() && p.isAlive)                        p.Task.PerformSequence(FleeTask);                        p.ChangeRelationship(group, Relationship.Hate);                    {                        // DO STUFF TO PED                    }                }                }            }        }                    Ped Zombie;                                                    private void DoTheZombie() {                        if (Exists(Zombie))                        Zombie.isRagdoll = false;                        Zombie = null;                        return;                                    }    }         ERROR    --->      Zombie = Player.GetTargetedPed(); {                    if (!Exists(Zombie)) return;                    Game.DisplayText("ZOMBIES!!!");                    Zombie.Euphoria.BodyBalance.Start(-1);                }                {                    if (!Exists(Zombie)) return;                    if (Zombie.isGettingUp) return; // wait until the zombie is standing                    if (!Zombie.isRagdoll) Zombie.Euphoria.BodyBalance.Start(-1);                    if (!Zombie.Euphoria.BodyBalance.isBalanced)                    { // get up again when fallen to the ground                        Zombie.isRagdoll = false;                        return;                    }                    Zombie.Euphoria.LeanToPosition.Amount = 1.0F;                    Zombie.Euphoria.LeanToPosition.ApplyAsForce = true;                    Zombie.Euphoria.LeanToPosition.Position = Player.Character.Position;                    Zombie.Euphoria.LeanToPosition.Start(); } }

But i get error at Zombie, It says: a namespace cannot directly contain members such as fields or methods

I want it to 1 script, so if you go around then you see some peds walking like zombies without you need to aim at them! cant find command, but i wanna find another command instead of you must aim so they become zombies. So i want all the text to go together, They attack everybody they see except their own zombie faction, Could you fix the problem ? xD

[L0uNGeR]

Your code is completely messed up, are you even using Visual Studio or?
Also, you can't do BodyBalance and Tasks at the same time, I've tried it.
You could however pause BodyBalance and do a task, then continue BodyBalance, but it looks awkward.

I did a test with the code below, right now I commented out the "PerformSequence" because it still needs a check to see if they already have this task.
If you un-comment the line, they keep restarting the Task so it looks weird.
For now, this works, everybody hates everybody, no special faction or anything, I'm still working on that.

EDIT: This is probably better for setting relationships:

World.SetGroupRelationship( RelationshipGroup group, Relationship level, RelationshipGroup targetgroup )

CODE

using System; using GTA; namespace MyTest {    public class MyTest : Script    {        TaskSequence FightTask;        public MyTest()        {            Interval = 1000;            FightTask = new TaskSequence();            FightTask.AddTask.FightAgainstHatedTargets(3, 5);            FightTask.AddTask.FightAgainst(Player);            this.Tick += new EventHandler(MyTest_Tick);        }        internal bool IsPedReady(Ped p)        {            return (p != null && p != Player.Character && p.Exists() && p.isAlive);        }        internal void SetPedHateEverybody(Ped p)        {            if (!p.Exists()) return;            foreach (RelationshipGroup group in Enum.GetValues(typeof(RelationshipGroup)))                p.ChangeRelationship(group, Relationship.Hate);        }        internal void MyTest_Tick(object sender, EventArgs e)        {            // Code in here is being run the whole time, according to "Interval"            foreach (Ped p in World.GetAllPeds())            {                if (IsPedReady(p))                {                    SetPedHateEverybody(p);                    //p.Task.PerformSequence(FightTask);                }            }        }    } }

Yeah sorry im still very nooby xd

but i tried atleast, ehm ok i take this code, but is it then possible to include the zombie thing aswell? becuase i want the zombie thing O.o

should i add it here?

SetPedHateEverybody(p);
//p.Task.PerformSequence(FightTask);

Zombie things
Zombie things
Zombie things
Zombie things
Zombie things
Zombie things

}
}
}
}
}

Yes it is possible, but it requires a much more advanced system to take care of the "BodyBalance" for ALL the zombies, instead of just 1.

Off topic:

You don't have to use the "internal" and "this" keywords (sorry forgot name of them), you can just do:

CODE

void myFunc() {} // and Tick += new .......

Not a big deal, just telling you so you save on redundant code.

Thanks for the heads up, but: Every example that I've seen used "this.tick" and "private void ...."
I only started using internal instead of private because I understood that it was better.
Why do all Hazard's examples use "this" and "private" ? I'm sure he's not a beginner...

[lindsayslorach]

I'm pretty sure variables and methods are private anyway, so there's no need to have the private keyword.

There could be reasons it's used in the examples you're using but in the above code it's not required as no other objects/instances/classes are being accessed anywhere. All the keywords are designed to allow access to other classes/instances etc, if you're not doing this then there is no need to use them.

Check out the MSDN website, it's got tons of great information on this type of thing.

Grabbed a few links for you dude, Access Modifiers, this.
