Databases and Projectiles

[Spikedude]

Can anyone either help me or link me to something that will help me with databases and projectiles on GS2? They're the two important things I have no understanding of. I know Java so the rest came very easy but I don't know any commands or anything for databases or projectiles. Thanks.

Database NPC's (Also known as DB NPCs) Are pretty useful can store flags into them, and can only be reached serverside, good for like logging stuff such as say a tip char. Can also be used say if the player is not online tell the DB NPC that when the player is online to do blah and such.

I know what DBs ARE, just not how to use them. Like, do I just put flags on them and then use getters and setters? Like I could have a string as a flag called current and say in the flags
current = BlackHolst Level4 BlazianBandits Level5 Pelikano Level1

then have methods like

NPC Code:

---

function getCurrent()

{

return current;

}



function addCurrent(str)

{

current += " " + str;

}



function deleteFirst

{

str[] = current.tokenize();

current = "";

for (i = 2; i < current.length(); i++)

{

current += " " + str[i];

}

}

---

or do they work differently?

I guess I'm asking: how do you access the flags of a database to modify or obtain data?

[Codein]

To access the variables stored in a db, use this:

PHP Code:

findnpc("DBname").varname = data; 


(serverside)

and to access to data inside the npc, use this.varname.

Spikedude, you're messing stuff. There's no such thing as private attribute here, it is all public, which means direct access.
And on function deleteFirst you're losing two tokens, not one.

[Spikedude]

deleteFirst was supposed to lose two tokens based on the way I was trying to set this script up. But I have other problems too. Like if a string has certain things in quotes and you tokenize, will it count the quoted part as one element or split it?

To access variables in GS2, use

obj.var

Also, so long as your object names are not awful, you can just do

mydbnpc.var (assuming you named your dbnpc mydbnpc). If you have wacky characters, try ("x39w-sfjefDD2").var

[salesman]

In the NPC script you can set the flags using this.var

PHP Code:

function onCreated() {
  this.foo = "hey dood sup";
} 


Then when you check the NPC flags you'll see 'foo=hey dood sup'

You can then also access it through any other serverside script with 'findnpc("NPCname").foo' or just simply NPCname.foo

Is a variable in a Database NPC not even readable clientside?

Yes it is, if you have a clientsided script in the same level as the DB NPC, assuming the variables you're trying to access is clientsided as well.
