Custom NPC

[lordhelmut]

Alright I need someone fairly good at scripting. I am trying to learn and I need a kinda mini tutorial here. Can someone take me through a short step by step process for scripting things like animals, baddies or anything with custom sprites. I kinda know something about u gotta make variables that deal with how many hearts and speed and such but thats about it. If someone is willing to help I would gladly appreciate it.

[lordhelmut]

just for an example lets use this...

I'll help you out as much as I can. First, you'll need to either know the dimensions of the image (like the width/height of each sprite, and the starting x/y of each sprite so that they're the same size). Then, you'd need to set variables like:
this.hearts=heartcount;
this.speed=speed; (normal speed is about 0.2 or 0.3, can't remember which one).
Then, you'd need to do an if (created){} stuff, which sets the variables, and the image and junk. You'd use showimg, for showing it. Then, you'd need to use a changeimgvis index,3; (3 is the same level as the player on the board). Then you'd need changeimgpart index,x,y,width,height; (x and y are the starting x/y of the current sprite, and width and height are how many pixels to display following the starting x/y).

That's all jumbled together, I know, so if you have problems understanding it (I have a lot of trouble understanding some of the things I write sometimes), let me know, and I'll spend a little more time on this sort of thing. Or just ask someone else. Either one works.

Thank you, the main part I need to focus on is the sprites changing part. Like how to make the sprites change or something. The script I have seen before were like dog.gif*64 bla bla and I need to figure that part out most =D

[Sennema]

Hmm... it might work that way, but I haven't seen anything like that. Say each sprite was a square that was 50*50 pixels each.

To get the first image you'd use something like

NPC Code:

---

showimg 101,bogo_dog0.gif,x,y;

changeimgpart 101,0,0,50,50;

changeimgvis 101,3;

---

That would show the first sprite, the still dog from behind. Now, say you wanted the image of the dog sitting down while facing toward the player. You'd just do something like:

NPC Code:

---

if(dir=2&&stuff){

changeimgpart 101,100,250,50,50;

}

---

That would take the image and edit the part that's showing, giving you the dog sitting down. The actual dimensions are a little different that a 200*300 pixel image, but that's the general idea. Hope that helped.

[lordhelmut]

I think there is some kinda formula that people use that changes the sprites

[Sennema]

Yeah, your probably right. But I don't know what it is... sorry.

[lordhelmut]

If I take it out of one of the NPC's on Babylon think you could figure it out?

Yeah, I could probably figure it out then. All I'd need would be the images and the parts of the script that do the showing (Don't worry I won't steal or anything, I'm not into that type of thing).

[lordhelmut]

found it!

if (this.dir==3) setgifpart b_greenbird.png,192,this.sprite*32,64,32;

its the last part of that...

mrmicro: no i was too busy picking my nose.

[Saga2001]

actually what i suggest is a simple code that is like x=dir*50 and than it places the cursor there, its very useful, does anyone know where i could get some idea of what all the drawingheights for changeimgvis are? cause i am in the dark on that one thing.

[btedji]

"npcprogramming.doc" in graal folder

Yeah, you should check the npcprogramming.doc, but basically it's like this:

1- below player
2- same level as player
3- above player
4- on the screen
and I heard that 5-10 draw overtop of 4, on the screen. I never read anything about that though...

[lordhelmut]

what is this? I saw it in one of Xaviars scripts its like dirgo = {-1,0,1,2,3} blah blah or something. I also saw it in a tutorial by Ace

[Saga2001]

wtfs you dont make any sense stop it!

[lordhelmut]

what would have to be added to a baddy to make it work for many players? I have had bad experiences with the bats and stuff on babylon and if 2 or more people come in they freeze

[lordhelmut]

// NPC made by Lord Helmut
//widthofsprites=91
//heightofsprites=105
if(created){
this.xpos=x;
this.ypos=y;
this.hearts=20;
this.speed=1;
this.dir=0;
this.sprite=0;
setimgpart #f,91*2,0,91,105;
}
if(playersays(hi)){
timeout=.05;
}
if (timeout){
if (this.xpos>playerx){this.xpos-=this.speed};
if (this.ypos<playery){this.ypos+=this.speed};
if (this.xpos<playerx){this.xpos+=this.speed};
if (this.ypos>playery){this.ypos-=this.speed};
timeout=.05;
}

I did this so far but the character wont move =(

[lordhelmut]

please help?

[Gohan43331]

add this in your timeout sequence:

NPC Code:

---

x = this.xpos;

y = this.ypos;

---

and you for the setimg part try this: (based off your second post's image;

NPC Code:

---

setimgpart #f,91*16,0,45.5,52.5;

---

and when that dog gets moving, it's super fast...

NPC Code:

---

this.speed=.3 // or .4 which is graalian speed(about)

---

G'luck mate,
Gohan

Character moving? Is the character supposed to move towards the dog or vica versa?
