Detecting Tiles on a Board
 

I know there's things for board[] and stuff, but I don't know how to use them. So to put it simply: Could someone explain to me how to use board[] or any other function to detect if a certain x,y is on a certain tile?

Thanks for your help!

board[] is outdated. Use tiles[]. Tiles[x,y] returns the value of the tile on that coordinate. If you want to find out the value of a tile, select it on the level in the editor and click "Export Tiles Array". (It's the button to the immediate right of the sign button.) That will give you the hex value of the tile, which you can use directly in scripts. (You don't have to convert it to decimal.)

I use it for weapons where you have to be on specific tile(s).
It goes like:
Or put all the tile values in a variable to make it easier to add and read.

What I usually do with checking if the player is on specific tiles is that i make an array:

NPC Code:

---

beontiles={0x0,0x1,0x10,0x1FF};

---

and this in the checking:

NPC Code:

---

if (tiles[playerx,playery] in beontiles) {

  //Do stuff

}

---

That be a good method. Yes indeed.

Argh sorry, not a variable an array.. I need to catch up :o!

You probably already know this, but just in case you dont... setting a variable as an array to use in the condition isn't necessary. You can just put {num,num2,num3,etc} directly in the if ().

Aye, but it's good practice to set them beforehand, isn't it?

I don't see how. It's just adding extra space to the script, and adding a variable that isn't necessary.

Yes yes it is.

What if you need to use it more than once? o.O

How?

That wasn't the case here, was it?

He was asking, it could help him and the forum starter to learn it?

It's a thread, not a forum.

Sure, it could, and it could also teach him to use variables every time he does something, which isn't always efficient.

What's wrong with using variables? Even if it's used only once, it isn't being inefficient -.- Who agrees with me?

Yes but it could save them in the future from starting another thread asking a question which is related to this thread..

When did I ever say there was anything wrong with EVER using variables? There's no reason to use them if they're simply going to be used once. That's like making a function just to do "say2 Hi;" and calling the function rather than using the actual command. Wasted space in the script. More to sift through.

As if it's not going to happen anyway. Besides, a different thread relating DIRECTLY to that topic would be more useful for people who don't know about it.

Ah okay, either way it's okay to do since people will read it where ever it is placed:megaeek:

So is VeX_RaT_Boy just using it once or are you assuming that? O.o

Well thanks for all your help everybody, lol.

Obviously an assumption, unless you thought I had talked to him elsewhere, which hasn't happened.

I know that.
My name is Kjetil.

I got 2 reasons for using a variable;

1. It looks nice if your going to have the array long: if (blah in {1,2,3})

That is ok, but what if it was up to 50?


2. When I script with variables I normally use it in more than one place.


Even though it wasn't more than 1 in this case, I did not post the whole script. It could've been longer.

...your point being? It's still going to be the same length as it would if it were assigned to a variable instead. ;)

NPC Code:

---

if (blah in {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15})

---

NPC Code:

---

test={

1,2,3,

4,5,6,

7,8,9,

10,11,12,

13,14,15};

if (blah in test)

---

See a diffrence? The first is a lot longer, and LOOK more messy. I don't really want this to turn into a flame-war. :\

Stupid question. Obviously there's a difference, however, it's a matter of personal opinion on what looks better.

Look above.

Supid questions are made by stupid people.

Another thing with board[] and tiles[]...

Is it possibile to use tiles[] to change the tile under the npc? because ive been working with trying to change tiles under and arround an npc and it goes like

NPC Code:

---

...

board[x+y*64] = 2079;

updateboard 0, 0, 10, 10;

...

---

So even when i used board[] or tiles[] with an array or value, it never changed the tile under the npc to anything else.

Notes:
In Theory "2079" is a tile value, i cant remember if it actually is or not, i just substituted that number.

I cant get either style to work, board[] or tiles[] to update the tiles under the npc

Yeah* go-boom did with a face moving, using tiles. He posted on the forums, It rocked :D

http://forums.graal2001.com/forums/s...ghlight=goboom

That's the link :]

tiles[30,30]=0x4A3;
updateboard 30,30,1,1;

would be better :)
Works even on serverside, then all people see it. When you do updateboard2 x,y,width,height; then the tile change is even saved to the level after a few minutes, the serveroption savelevels=true must be set.
(saving not enabled on gmaps yet)

Stefan, don't ever stop coming here, reading and giving us gems of information everyday!

Lol.
I was just wondering if it could be used serverside too. =P

o wow updateboard2, didnt know that. Now you can make a online level editor o.O that's cool =)

Actually I was going to make a pretty simple tile layer. You would click, and it would lay that tile at the mousex/y. You would be able to change the tile type, the width(in tiles) that it would lay, and the height it would lay. Erm, if the width was 2, it would lay 2 of those tiles starting from the mousex, and continue right one tile. =)

Easy, Ive already done it, i think Riot may have? I can remember someone else boasting their completion of one

That's easy, and cool a new command I didn't know!

I never posted one. Though I do know if you search the forums you will find atleast an old one.

like "message" maybe? :)
