Introduction:

Hey everyone, today I'll show you and explain how to make "gates" in samp
In case you are wondering what I mean by that, it is a gate that opens or closes when the user interacts
I will show you guys several different ways for different results, you pick whatever you want
In this tutorial I will be using Zeex's include zcmd

Content Table:

• Gate activated by command
• Gate activated by key
• Gate with automatic closing
• Gate activated by proximity

¤ Gate activated by command:

Well first of all, we will define the position of the gate open - closed, and declare the following variables:

pawn Code:

new GateGrove; //Id to be assigned to the gate
new isOpen[MAX_OBJECTS]; //Variable to check if the object is open

#define XYZ_Open 2464.6001000,-1668.8000500,14.0000000
#define XYZ_Closed 2464.6999500,-1659.3000500,14.0000000
//Note: They are necessary for the tutorial, and I recommend using them since they'll make your life much easier

Once the variables are declared, we will continue to assign the id to the object, while creating it:

pawn Code:

GateGrove = CreateObject(975,2464.6999500,-1659.3000500,14.0000000,0.0000000,0.0000000,88.0000000);
//Make sure that it's either on "OnGameModeInit" or "OnFilterScriptInit" due that it needs to be created when the server starts running

Finally, we create the command "/gate" to open or close the door, depending of it's state:

pawn Code:

command(gate,playerid,params[])
{
    if(IsPlayerInRangeOfPoint(playerid, 15.0, XYZ_Closed)) //If it is in range of the player
    {
        if(isOpen[GateGrove] == 0) //If the variable is equal to 0 (gate is closed)..
        {
            MoveObject(GateGrove, XYZ_Open, 2.00); //Move the gate to the appropriate coords
            isOpen[GateGrove] = 1; //Set the variable to 1 (gate is now open)
        }
        else if(isOpen[GateGrove] == 1) //If the variable is equal to 1 (gate is open)..
        {
            MoveObject(GateGrove, XYZ_Closed, 2.00); //Move the gate to the appropriate coords
            isOpen[GateGrove] = 0; //Set the variable to 0 (gate is now closed)
        }
    }
    return 1;
}

¤ Gate activated by key:

Well first of all, we will define the position of the gate open - closed, and declare the following variables:

pawn Code:

new GateGrove; //Id to be assigned to the gate
new isOpen[MAX_OBJECTS]; //Variable to check if the object is open

#define XYZ_Open 2464.6001000,-1668.8000500,14.0000000
#define XYZ_Closed 2464.6999500,-1659.3000500,14.0000000
//Note: They are necessary for the tutorial, and I recommend using them since they'll make your life much easier

Once the variables are declared, we will continue to assign the id to the object, while creating it:

pawn Code:

GateGrove = CreateObject(975,2464.6999500,-1659.3000500,14.0000000,0.0000000,0.0000000,88.0000000);
//Make sure that it's either on "OnGameModeInit" or "OnFilterScriptInit" due that it needs to be created when the server starts running

Finally, we add the open-close code on callback "OnPlayerKeyStateChange":

pawn Code:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if ((newkeys & KEY_YES) && !(oldkeys & KEY_YES)) //If key "Y" is pressed..
    {
        if(IsPlayerInRangeOfPoint(playerid, 15.0, XYZ_Closed)) //Player is in range of gate..
        {
            if(isOpen[GateGrove] == 0) //If the variable is equal to 0 (gate is closed)..
            {
                MoveObject(GateGrove, XYZ_Open, 2.00); //Move the gate to the appropriate coords
                isOpen[GateGrove] = 1; //Set the variable to 1 (gate is now open)
            }
            else if(isOpen[GateGrove] == 1) //If the variable is equal to 1 (gate is open)..
            {
                MoveObject(GateGrove, XYZ_Closed, 2.00); //Move the gate to the appropriate coords
                isOpen[GateGrove] = 0; //Set the variable to 0 (gate is now closed)
            }
        }
    }
    return 1;
}

¤ Gate with automatic closing:

Well first of all, we will define the position of the gate open - closed, and declare the following variables:

pawn Code:

new GateGrove; //Id to be assigned to the gate
new isOpen[MAX_OBJECTS]; //Variable to check if the object is open
new isAutomatic[MAX_OBJECTS]; //Variable to check if the gate is automatic closing type
new isIndpendent[MAX_OBJECTS]; //Variable to check if the gate is triggered by proximity


#define XYZ_Open 2464.6001000,-1668.8000500,14.0000000
#define XYZ_Closed 2464.6999500,-1659.3000500,14.0000000
//Note: They are necessary for the tutorial, and I recommend using them since they'll make your life much easier

Once the variables are declared, we will continue to assign the id to the object, while creating it:

pawn Code:

GateGrove = CreateObject(975,2464.6999500,-1659.3000500,14.0000000,0.0000000,0.0000000,88.0000000);
isAutomatic[GateGrove] = 1; //Set it to automatic
//Make sure that it's either on "OnGameModeInit" or "OnFilterScriptInit" due that it needs to be created when the server starts running

Now we create the command that will only open the gate:

pawn Code:

command(autogate,playerid,params[])
{
    if(IsPlayerInRangeOfPoint(playerid, 15.0, XYZ_Closed)) //If player is in range of gate..
    {
        if(isOpen[GateGrove] == 0) //If the variable is equal to 0 (gate is closed)..
            {
                MoveObject(GateGrove, XYZ_Open, 2.00); //Move the gate to the appropriate coords
                isOpen[GateGrove] = 1; //Set the variable to 1 (gate is now open)
            }
    }
    return 1;
}

Finally, we add the code for callback "OnObjectMoved":

pawn Code:

public OnObjectMoved(objectid)
{
    if(objectid == GateGrove) //If the object that moved was our gate
    {
        if(isAutomatic[GateGrove] == 1 || isIndependent[GateGrove]) //If it is either automatic closing or independent
        {
            MoveObject(GateGrove, XYZ_Closed, 2.00); //Move the gate to the appropriate coords
            isOpen[GateGrove] = 0; //Set the variable to 0 (gate is now closed)
        }
    }
    return 1;
}

¤ Gate activated by proximity:

Well first of all, we will define the position of the gate open - closed, and declare the following variables:

pawn Code:

new GateGrove; //Id to be assigned to the gate
new isOpen[MAX_OBJECTS]; //Variable to check if the object is open
new isAutomatic[MAX_OBJECTS]; //Variable to check if the gate is automatic closing type
new isIndpendent[MAX_OBJECTS]; //Variable to check if the gate is triggered by proximity

#define XYZ_Open 2464.6001000,-1668.8000500,14.0000000
#define XYZ_Closed 2464.6999500,-1659.3000500,14.0000000
//Note: They are necessary for the tutorial, and I recommend using them since they'll make your life much easier

Once the variables are declared, we will continue to assign the id to the object, while creating it:

pawn Code:

GateGrove = CreateObject(975,2464.6999500,-1659.3000500,14.0000000,0.0000000,0.0000000,88.0000000);
isIndependent[GateGrove] = 1; //Set it to independent
for(new i; i < MAX_PLAYERS; i++) //Loop for every player
    {
        SetTimerEx("NearGate", 2000, true, "i", i); //Check every 2 seconds if player is near a gate
    }
//Make sure that it's either on "OnGameModeInit" or "OnFilterScriptInit" due that it needs to be created when the server starts running

Now we create the public and the forward for the checking function:

pawn Code:

forward NearGate(playerid);
public NearGate(playerid)
{
    if(IsPlayerInRangeOfPoint(playerid, 15.0, XYZ_Closed)) //If player is in range of gate..
    {
        if(isIndependent[GateGrove] == 1) // If it is independent..
        {
            if(isOpen[GateGrove] == 0) //If the variable is equal to 0 (gate is closed)..
            {
                MoveObject(GateGrove, XYZ_Open, 2.00); //Move the gate to the appropriate coords
                isOpen[GateGrove] = 1; //Set the variable to 1 (gate is now open)
            }
        }
    }
    return 1;
}

Finally, we add the code for callback "OnObjectMoved":

pawn Code:

public OnObjectMoved(objectid)
{
    if(objectid == GateGrove) //If the object that moved was our gate
    {
        if(isAutomatic[GateGrove] == 1 || isIndependent[GateGrove]) //If it is either automatic closing or independent
        {
            MoveObject(GateGrove, XYZ_Closed, 2.00); //Move the gate to the appropriate coords
            isOpen[GateGrove] = 0; //Set the variable to 0 (gate is now closed)
        }
    }
    return 1;
}
