(help)store floating variable to array - GianYagami - 01.01.2015

Hello, how to store floating variable to array? I just follow like this thread https://sampforum.blast.hk/showthread.php?tid=243175. here's my code:

my code before using array method:
Код:
	{

		    SetPlayerFacingAngle(playerid, HospitalSpawns[0][3]);
		    SetCameraBehindPlayer(playerid);
		    return 1;
  		}
		else if(DistanceAll_Saints_GH < DistanceCounty_GH && DistanceCrippenMemorial_H && DistanceAngelP_MC && DistanceSanFierro_MC && DistanceElQuebrados_MC && DistanceLasVenturas_H)
		{
		    SetPlayerPos(playerid, HospitalSpawns[1][0], HospitalSpawns[1][1], HospitalSpawns[1][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[1][3]);
		    SetCameraBehindPlayer(playerid);
  		}
  		else if(DistanceCrippenMemorial_H < DistanceAll_Saints_GH && DistanceCounty_GH && DistanceAngelP_MC && DistanceSanFierro_MC && DistanceElQuebrados_MC && DistanceLasVenturas_H)
  		{
		    SetPlayerPos(playerid, HospitalSpawns[2][0], HospitalSpawns[2][1], HospitalSpawns[2][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[2][3]);

  		}
  		else if(DistanceAngelP_MC < DistanceCrippenMemorial_H && DistanceAll_Saints_GH && DistanceCounty_GH && DistanceSanFierro_MC && DistanceElQuebrados_MC && DistanceLasVenturas_H)
  		{
		    SetPlayerPos(playerid, HospitalSpawns[3][0], HospitalSpawns[3][1], HospitalSpawns[3][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[3][3]);
		    SetCameraBehindPlayer(playerid);
  		}
  		else if(DistanceSanFierro_MC < DistanceAngelP_MC && DistanceCrippenMemorial_H && DistanceAll_Saints_GH && DistanceCounty_GH && DistanceElQuebrados_MC && DistanceLasVenturas_H)
  		{
		    SetPlayerPos(playerid, HospitalSpawns[4][0], HospitalSpawns[4][1], HospitalSpawns[4][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[4][3]);
		    SetCameraBehindPlayer(playerid);
  		}
  		else if(DistanceElQuebrados_MC < DistanceSanFierro_MC && DistanceAngelP_MC && DistanceCrippenMemorial_H && DistanceAll_Saints_GH && DistanceCounty_GH && DistanceLasVenturas_H)
  		{
		    SetPlayerPos(playerid, HospitalSpawns[5][0], HospitalSpawns[5][1], HospitalSpawns[5][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[5][3]);
		    SetCameraBehindPlayer(playerid);
		}
  		else if(DistanceLasVenturas_H < DistanceElQuebrados_MC && DistanceSanFierro_MC && DistanceAngelP_MC && DistanceCrippenMemorial_H && DistanceAll_Saints_GH && DistanceCounty_GH)
  		{
		    SetPlayerPos(playerid, HospitalSpawns[6][0], HospitalSpawns[6][1], HospitalSpawns[6][2]);
		    SetPlayerFacingAngle(playerid, HospitalSpawns[6][3]);
		    SetCameraBehindPlayer(playerid);
		}
	}
by using this, player always spawn in county general hospital and all saints general hospital, because it just compare two variable. I guess the way I unstructured.

HospitalSpawns[][]
Any number between the first pair of bracket stand for which coordinate set to use.
For example: HospitalSpawns[0][] means: the first line of coordinates.
With this comes a second pair of brackets which stand for the amount of parameters in each line of coordinates.
For example: HospitalSpawns[][0] means: the first parameter in the coordinate line (The X coordinate).

And you can now combine these two.
pawn Код:
HospitalSpawns[0][0] //The first set of coordinates and the X-coordinate.
pawn Код:
HospitalSpawns[0][1] //The first set of coordinates and the Y-coordinate.
pawn Код:
HospitalSpawns[0][2] //The first set of coordinates and the Z-coordinate.
pawn Код:
HospitalSpawns[0][3] //The first set of coordinates and the Angle-coordinate.
You can easily implement this in a function such as SetPlayerPos.
pawn Код:
SetPlayerPos(playerid, HospitalSpawns[0][0], HospitalSpawns[0][1], HospitalSpawns[0][2]); //The first set of coordinates and the X [0], Y [1] and Z-coordinate [2].
pawn Код:
SetPlayerFacingAngle(playerid, HospitalSpawns[0][3]); //The first set of coordinates and the Angle [3] coordinate.
EDIT: you can then use the same working style for the distance floating.

Re: (help)store floating variable to array - Virtual1ty - 01.01.2015

Why waste space allocating an array? I recommend that you calculate the distance from the hospitals immediately when a player dies, then do whatever you want with that.
Also another issue I found in your code is the "dead" variable, it will only work for one player alone - make it a per-player var.
pawn Код:
#define FLOAT_INFINITY (Float:0x7F800000)
new Float:gClosestHospitalDist[MAX_PLAYERS]; // if for some reason you have to save the distance
new gClosestHospital[MAX_PLAYERS]; // holds the index to the closest hospital
public OnPlayerDeath(playerid, killerid, reason)
{
    // rest of code.. 
    new Float:dist = FLOAT_INFINITY;
    for (new i = 0; i < sizeof(HospitalSpawns); i++)
    {
        gClosestHospitalDist[playerid] = GetPlayerDistanceFromPoint(playerid, HospitalSpawns[i][0], HospitalSpawns[i][1], HospitalSpawns[i][2]);
        if (gClosestHospitalDist[playerid] < dist)
        {
            dist = gClosestHospitalDist[playerid]; 
            gClosestHospital[playerid] = i; 
        }
    }
    return 1;
}
Now you simply use gClosestHospital[playerid] as the index for the HospitalSpawns array when you are setting the player position OnPlayerSpawn, you don't need multiple lines of the same code, no switch-case etc.

Yes, I am write like that, and I create distance variable for store distance. But, I don't know how to find smallest variable. thank you btw

    {
        gClosestHospitalDist[playerid] = GetPlayerDistanceFromPoint(playerid, HospitalSpawns[i][0], HospitalSpawns[i][1], HospitalSpawns[i][2]);
        if (gClosestHospitalDist[playerid] < dist)
        {
            dist = gClosestHospitalDist[playerid]; 
            gClosestHospital[playerid] = i; 
        }
    }
    return 1;
}
Now you simply use gClosestHospital[playerid] as the index for the HospitalSpawns array when you are setting the player position OnPlayerSpawn, you don't need multiple lines of the same code, no switch-case etc.
I don't know how to write a looping. thank you for teach me
I use boolean for checking if player spawn after killed or spawn after joined.
It's hard to understanding looping.
EDIT: how to call gClosestHospital as array? I am use this but didn't work:
pawn Код:
public OnPlayerSpawn(playerid)
{
    if(dead==true)
    {
    SetPlayerPos(playerid, HospitalSpawns[gClosestHospital][0], HospitalSpawns[gClosestHospital][1], HospitalSpawns[gClosestHospital][2]);
    SetPlayerFacingAngle(playerid, HospitalSpawns[gClosestHospital][3]);
    setCaneraBehindPlayer(playerid);
    return 1;
    }
    if(dead==false)
    {
    SetPlayerPos(playerid, 1714.9219,-1948.8318,14.1172);
    SetPlayerFacingAngle(playerid, 357.5184);
    SetCameraBehindPlayer(playerid);
    return 1;
    }
    return 0;
}
EDIT: now is work, I create new variable for gClosestHospital
pawn Код:
public OnPlayerSpawn(playerid)
{
    if(dead==true)
    {
    new i = gClosestHospital[playerid];
    SetPlayerPos(playerid, HospitalSpawns[i][0], HospitalSpawns[i][1], HospitalSpawns[i][2]);
    SetPlayerFacingAngle(playerid, HospitalSpawns[i][3]);
    SetCameraBehindPlayer(playerid);
    }

    if(dead==false)
    {
    SetPlayerPos(playerid, 1714.9219,-1948.8318,14.1172);
    SetPlayerFacingAngle(playerid, 357.5184);
    SetCameraBehindPlayer(playerid);
    return 1;
    }
    return 0;
}
Still no idea to make per player boolean. because I don't like use integer just for true false.

Re: (help)store floating variable to array - Virtual1ty - 02.01.2015

Just make a simple variable(called an array, actually) that holds MAX_PLAYERS items. You can still keep the "bool:" tag if you wish.
Also, be sure to declare it outside any function or callback (global variable).
Example:
pawn Код:
new bool:dead[MAX_PLAYERS];
// And you use it like e.g. dead[playerid] under OnPlayerDeath
// The way you have it now will only ever work for one player alone

Okay, got it. Thank you.
