Hello everybody !

These days I'm looking on the U-RP Gamemode that was released, and I try to add 2 more ranks for factions, I mean that factions will now have 8 ranks, not 6 anymore, everything was great until I met arrays.

I compiled, and this is what I get :

Ok so for example let's take lines 8861-8862 (where I get the error !):

pawn Код:

strmid(FactionRank[1][7], arrCoords[46], 0, strlen(arrCoords[46]), 255);
        strmid(FactionRank[1][8], arrCoords[47], 0, strlen(arrCoords[47]), 255);

Now let's take the 6 lines before these 2 lines 8855-8860 :

pawn Код:

strmid(FactionRank[1][1], arrCoords[40], 0, strlen(arrCoords[40]), 255);
        strmid(FactionRank[1][2], arrCoords[41], 0, strlen(arrCoords[41]), 255);
        strmid(FactionRank[1][3], arrCoords[42], 0, strlen(arrCoords[42]), 255);
        strmid(FactionRank[1][4], arrCoords[43], 0, strlen(arrCoords[43]), 255);
        strmid(FactionRank[1][5], arrCoords[44], 0, strlen(arrCoords[44]), 255);
        strmid(FactionRank[1][6], arrCoords[45], 0, strlen(arrCoords[45]), 255);

What is the problem ?
Can someone explain to me how arrays really work in this case ?
What have I done wrong ?
How may I correct it ?
Do you have any tips to give to me about arrays ?

Thanks in advance.

Well after many googling I can't really find any clear explanation about this. Some does ? Thanks.

Re: Little problem about arrays. - Vince - 24.06.2013

Keep in mind that array indices start at 0, not 1. That means if you have an array with 6 slots, you access them with indices 0 through 5.

Re : Little problem about arrays. - Kethrios - 24.06.2013

I try to understand what you're explaining, I just can't really imagine, can you please illustrate ?

Is the problem related to this ?

pawn Код:

new FactionRank[11][7][32];

I'm reading some tutorial about arrays, this a three dimensional one isn't it ? What can you tell me about it ?
Thanks for helping me.

EDIT :

pawn Код:

new FactionRank[11][7][32];

It must be changed to

pawn Код:

new FactionRank[11][9][32];

then ?

EDIT 2 :
Well the situation changed.

Now my errors are :

I'll look for more informations about this.

EDIT 3 : I solved the problem by changing

pawn Код:

new arrCoords[60][512];

pawn Код:

new arrCoords[79][512];

Thanks a lot !
