Question: quite simple. - Dokins - 17.01.2012

Take for instance that I want to create say 5 gas stations, How would I check if the person is in range of any of them without having to use || each time in an if statement?

Use switch statement.

Well is there any limit to the amount of times using it? I worry,I was just wondering if there was another way around it, how would I create a thing like random messages? as in? Like Welcome to the server, every 15 minutes.

There is no issue with using if statements as it evaluates each condition individually. Usage of logical operators (most notable ||) within a single expression is reliable as the condition is passed quite quickly to the next statement. As stated there are alternative methods than doing what you've requested.

You can make an array with all the possible gas stations and then loop all over them, checking if you are near any of these gas stations this way:

This is an example of ****** idea

pawn Код:

enum GasStationEnum
{
    Float:gas_x,
    Float:gas_y,
    Float:gas_z,
}
// Each gas station will have 3 arguments: the x, y, and z positions.

new gGasStations[][GasStationEnum] =
{
    {1381.866699, 459.125488, 20.345203},
    {-1328.8250,2677.2173,49.7665},
    {656.4265,-559.8610,16.5015}
};
// ^ You can add your own

CMD:fill( playerid, params[] ) // example command
{
    for( new i = 0; i < sizeof( GasStationEnum ); i++ ) // We loop all the possible elements in the array
    {
        if ( IsPlayerInRangeOfPoint( playerid, 5.0, gGasStations[i][gas_x], gGasStations[i][gas_y], gGasStations[i][gas_z] ) )
        {
            // do something
        }
    }
    return 1;
}

The only limit is a slower code once you have an extreme ammount of gas stations!
