I want to allow players to challenge each other to a quatermile race on wich they can bet money (or even pink slips!).
I try to set a command "/drag" to create a check point 400m in front of the player's car.

Here is the script I know there's is alot missing but this is the core of the command when i try it it set the checpoint at 0,0,0. Also I need to figure out how adjust the Z coordinate of the checkpoint so it won't be underground or in the sky and if anyone as a betting system (ex: /dice [playerid][amount]) that would be great because it's script should the info I need to complete this.

Quote:

public OnPlayerCommandText(playerid, cmdtext[]) { if (strcmp("/drag", cmdtext, true, 10) == 0) { new float:A; new float:deltaX; new float:deltaY; new float:deltaZ; new float, float:y, float:z; GetPlayerPos(playerid, x, y, z); GetPlayerFacingAngle(playerid, A); deltaX=(floatsin(A)*400); deltaY=(floatcos(A)*400); SetPlayerRaceCheckpoint(playerid, 2, x+deltaX, y+deltaY, z, x+deltaX, y+deltaY, z,5); return 1; } return 0; }

Ok I got it to work but only when i'm out of the car when I try it from onside the checkpoint appears at the right distance but always north of me, it's like the getplayerfacingangle doesn't register when in a car.

Here are my new codes

//GET X Y IN FRONT OR BEHIND----------------------------------------------------
stock GetXYInFrontOfPlayer(playerid,&Float:x,&Float:y,Float:dis)
{
new float:pos[3];
new float:A;
GetPlayerPos(playerid,pos[0],pos[1],pos[2]);
GetPlayerFacingAngle(playerid,A);
GetXYInFrontOfPoint(pos[0],pos[1],x,y,A,dis);
}

stock GetXYBehindPlayer(playerid,&Float:x,&Float:y,Float:dis)
{
new float:pos[3];
new float:A;
GetPlayerPos(playerid,pos[0],pos[1],pos[2]);
GetPlayerFacingAngle(playerid,A);
GetXYBehindPoint(pos[0],pos[1],x,y,A,dis);
}

stock GetXYInFrontOfPoint(Float:x,Float:y,&Float:x2,&Float:y2,Float:A,Float:distance)
{
x2 = x + (distance * floatsin(-A,degrees));
y2 = y + (distance * floatcos(-A,degrees));
}

stock GetXYBehindPoint(Float:x,Float:y,&Float:x2,&Float:y2,Float:A,Float:distance)
{
x2 = x - (distance * floatsin(-A,degrees));
y2 = y - (distance * floatcos(-A,degrees));
}

	GetXYInFrontOfPlayer(playerid,X,Y,400);
	GetPlayerPos(playerid,x,y,z);
	SetPlayerCheckpoint(playerid,X,Y,z,5);
	return 1;

Thx yezizhu your script is very good(compact & effective), but I fixed it by creating a custom function wich I'll be able to use at any time for other commands.

I searched the forum and tutorials for 2 days to figure how to put something in front of a player and I've realized that this is something every new scripter will strugle with. So, here's how I did it. Now I should thx every one that helped by sharing info but at the moment I need to sort out the bits of code and where they came from. I will give credits to the people that helped later on.

Put this somewhere at the bottom of your script, make sure it's not in any callback or function ( between two: [])

//GET X Y IN FRONT OR BEHIND PLAYER---------------------------------------------

GetXYBehindPoint(pos[0],pos[1],x,y,A,dis);
}

//GET X Y IN FRONT/BEHIND/LEFT/RIGHT OF POINT-----------------------------------

stock GetXYInFrontOfPoint(Float:x,Float:y,&Float:x2,&Float:y2,Float:A,Float:distance)
{
x2 = x + (distance * floatsin(-A,degrees));

{

{
x2 = x - (distance * floatsin(-A+90.0,degrees));
y2 = y - (distance * floatcos(-A+90.0,degrees));
}

//------------------------------------------------------------------------------

//GET X Y IN FRONT OR BEHIND OF VEHICLE-----------------------------------------
stock GetXYInFrontOfVehicle(playerid,&Float:x,&Float:y,Float:dis)
{
new currentveh;
new float:pos[3];
new float:A;
currentveh = GetPlayerVehicleID(playerid);
GetVehiclePos(currentveh,pos[0],pos[1],pos[2]);
GetVehicleZAngle(currentveh,A);
GetXYInFrontOfPoint(pos[0],pos[1],x,y,A,dis);
}

new float:pos[3];
new float:A;

GetVehicleZAngle(currentveh,A);
GetXYBehindPoint(pos[0],pos[1],x,y,A,dis);
}
//------------------------------------------------------------------------------

To spawn something in front, behind, on the left or on the right you can now use the GetXY...OfPlayer() or GetXY...OfVehicle() functions just choose the distance between the player and the spawn point and use these coordinate in the code, like this:

Код:

{
	new currentveh;
	new float:x, float:y, float:z, float:X, float:Y;
	currentveh = GetPlayerVehicleID(playerid);
	GetXYInFrontOfVehicle(playerid,X,Y,400);
	GetVehiclePos(currentveh,x,y,z);
	SetPlayerCheckpoint(playerid,X,Y,z,10);
	return 1;
}

Enjoy!! & keep me posted :P

bahaaa, post in useful function.
You done the job, nice!

My first script is almost done! but I get 3 errors when I try to compile can some1 help plz

dcmd(drag0,5,cmdtext)

should add in OnPlayerCommandText

[JadedJ]

Thx now it compile but when I tested it with my friend it kinda worked the first time but when he tried to challenge me he spawned without his car then he crashed

I think it has something to do with how I indexed my arrays

Код:

//PUBLIC ARRAYS & VARS----------------------------------------------------------

new targetid, bet;

new challenger[MAX_PLAYERS];
SetChallengerValue(playerid, value)
{
	challenger[targetid] = playerid;
}

new challengerveh[MAX_PLAYERS];
SetChallengerVehValue(playerid, value)
{
	challengerveh[targetid] = GetPlayerVehicleID(playerid);
}

new stakes[MAX_PLAYERS];
SetStakesValue(playerid, value)
{
	stakes[targetid] = bet;
}

[yezizhu]

It seems no problem here, are you sure player crashed when using the command?

[JadedJ]

Yes I"m sure it crashed when he used the command but since then I've edited the script so it reset the arrays after a race. Is there anything like a checkpoint id so that when I use the OnPlayerEnterRaceCheckpoint callback to declare the winner it doesn't conflict with other races going on?
