[HELP] Show list in DialogStyleList with 'if' possible strcat - iryston - 13.08.2014

Hi, i want put in Dialog a list with itens of player, for example.
I have Item 1, item 2 and item 4;

and i want show, in dialog.

pawn Код:

if(PlayerHaveEagle == 1)
 {
    format(string,sizeof(string),"Item 1: Eagle (Have)\n");
 }
 else{
    format(string,sizeof(string),"Item 1: Eagle (Don't Have)\n");
 }
 if(PlayerHaveKnife == 1)
 {
    format(string,sizeof(string),"Item 1: Knife (Have)\n");
 }
 else{
    format(string,sizeof(string),"Item 1: Knife (Don't Have)\n");
 }if(PlayerHaveShotgun == 1)
 {
    format(string,sizeof(string),"Item 1: ShotGun (Have)\n");
 }
 else{
    format(string,sizeof(string),"Item 1: ShotGun (Don't Have)\n");
 }
 strcat(str,string);
 ShowPlayerDialog(playerid, DialogWeapons, DIALOG_STYLE_LIST, "Chose a weapon to get:", str, "Select", "Cancel");

Is only a base of my idea, so don't have script complete, i need only base to create correct, this method is correct?

But, how show in dialog it? with strcat?

Its not ok because you can see only last item, use strcat, char array and packed strings

pawn Код:

static itemstr[128 char];

if(PlayerHaveEagle == 1) itemstr = !"Item 1: Eagle (Have)\n";
else itemstr = !"Item 1: Eagle (Don't Have)\n";

if(PlayerHaveKnife == 1) strcat(itemstr,!"Item 1: Knife (Have)\n");
else strcat(itemstr,!"Item 1: Knife (Don't Have)\n");

if(PlayerHaveShotgun == 1) strcat(itemstr,!"Item 1: ShotGun (Have)");
else strcat(itemstr,!"Item 1: ShotGun (Don't Have)");

show itemstr

Very thanks, work.

But if i want put a string in itemstr? example:

pawn Код:

itemstr = !"Item 1: Eagle (Have) Ammo: %i\n",EagleAmo;

Is wrong, the pawn don't show error, but don't work, how be?

Thanks!

You need use 'format' for this

pawn Код:

static itemstr[128];

if(PlayerHaveEagle == 1) format(itemstr,sizeof(itemstr),"Item 1: Eagle (Have) Ammo: %i\n",EagleAmo);
else itemstr = "Item 1: Eagle (Don't Have)\n";

if(PlayerHaveKnife == 1) format(itemstr,sizeof(itemstr),"%sItem 1: Knife (Have) Ammo: %i\n",itemstr, KnifeAmo);
else strcat(itemstr,"Item 1: Knife (Don't Have)\n");

if(PlayerHaveShotgun == 1) format(itemstr,sizeof(itemstr),"%sItem 1: ShotGun (Have) Ammo: %i",itemstr, ShotGunAmo);
else strcat(itemstr,"Item 1: ShotGun (Don't Have)");
