Checking What Co-ords are Closest to a Player. - Ciarannn - 22.02.2015

Title says it all.

How do I cycle through lets say 8 co-ordinates and check what co-ordinate the player is closest to?

Re: Checking What Co-ords are Closest to a Player. - Crayder - 22.02.2015

pawn Код:

new shortest=-1, Float:shortdistance=-1;
for(new x; x<8; x++)
{
    if(GetPlayerDistanceFromPoint(playerid, pos[x][PosX], pos[x][PosY], pos[x][PosZ]) < shortdistance)
    {
        shortest = x;
        shortdistance = GetPlayerDistanceFromPoint(playerid, pos[x][PosX], pos[x][PosY], pos[x][PosZ]);
    }
}

Wrote quickly but you should get the idea. I typed this on my iPad so it's just a representation.

I don't quite understand what this code does, could you compare these checkpoints for me?

Thanks man.

This is not working, I tried it but I'm just getting errors. This is what I have:

Top of Script:

pawn Код:

new Float:GPSBANKS[][3] =
{
    {2436.6328,2376.5159,10.8203},
    {-179.1866,1133.1125,19.7422},
    {-828.0347,1504.3336,19.8416},
    {-1530.9633,2591.6548,55.8359},
    {-227.2883,2711.7888,62.9766},
    {2085.6655,2054.9348,11.0579}
};

Code with the errors:

pawn Код:

new shortest=-1, Float:shortdistance=-1;
for(new x; x<6; x++)
{
    if(GetPlayerDistanceFromPoint(playerid, GPSBANKS[x][PosX], GPSBANKS[x][PosY], GPSBANKS[x][PosZ]) < shortdistance) //line 28785
    {
        shortest = x; //line 28787
        shortdistance = GetPlayerDistanceFromPoint(playerid, GPSBANKS[x][PosX], GPSBANKS[x][PosY], GPSBANKS[x][PosZ]); //line 28788
        SetPlayerCheckpoint(playerid, PosX, PosY, PosZ, 7.0); //line 28789
    }
}

Errors:

Can someone shed some light?

Код:

new shortest = -1, Float:shortdistance= 100.0, Float:distance;

for(new x; x != sizeof GPSBANKS; x++)
{
	if((distance = GetPlayerDistanceFromPoint(playerid, GPSBANKS[x][0], GPSBANKS[x][1], GPSBANKS[x][2])) < shortdistance) //line 28785
	{
		shortest = x;
		shortdistance = distance;
	}
	if(shortest != -1) SetPlayerCheckpoint(playerid, GPSBANKS[shortest][0], GPSBANKS[shortest][1], GPSBANKS[shortest][2], 7.0);
}

Should work, figure it out on your own next time, not only "give code".

I spent a half an hour trying to get the code working, I didn't just "give code". Also, the point of this forums is to help you when your stuck, it's not about figuring it out yourself. I couldn't get it working so I asked.

Thanks, I've seen you helping around the forums. Keep it up!
