[Help] Simple Speed Boost when you press KEY_FIRE - Toni - 12.06.2010

Hello, I was just wondering..how do you create a speed boost on key_fire?

I've tried it with SetPlayerVelocity -- GetPlayerVelocity but I can't figure it out. Please help heh.

Re: [Help] Simple Speed Boost when you press KEY_FIRE - DJDhan - 12.06.2010

At the top somewhere:

Code:

#define HOLDING(%0) \
	((newkeys & (%0)) == (%0))

Code:

OnPlayerKeyStateChange(playerid,newkeys,oldkeys)
{
  if(IsPlayerInAnyVehicle(playerid))
  {
      
    if (HOLDING( KEY_FIRE ))
    {
       do
        {
        new Float:x,Float:y,Float:z,vehid; vehid=GetPlayerVehicleID(playerid);
        GetVehicleVelocity(vehid,x,y,z); 
        SetVehicleVelocity(vehid,x+30,y+30,z+30);
        } while(x<200 && y<200 && z<200);
    }
  }
  return 1;
}

What is on line 1391?

Re: [Help] Simple Speed Boost when you press KEY_FIRE - Toni - 12.06.2010

} while(x<200 && y<200 && z<200);

Re: [Help] Simple Speed Boost when you press KEY_FIRE - TheInnocentOne - 12.06.2010

pawn Code:

} while(x < 200 && y < 200 && z < 200);

Re: [Help] Simple Speed Boost when you press KEY_FIRE - Toni - 12.06.2010

adding spaces will help?

I'll still get the same error.

[*] Velocities need to keep their sign for direction. If you add onto a velocity you're going to slow the vehicle down if the velocity was for example -30.0 (-30 + 30 = 0, stopped completely!)[*] You have an infinite loop. There is absolutely no assignment in your code, if the velocities were all < 200 to start with then the code would never stop executing.[*] You're getting the above error because you defined your check variables inside the loop. The loop check is not in the same scope as the variable creation.

pawn Code:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
  if(IsPlayerInAnyVehicle(playerid))
  {
      
    if (newkeys & KEY_FIRE)
    {
        new
          Float:x, Float:y, Float:z, vehid;

        vehid = GetPlayerVehicleID(playerid);


        GetVehicleVelocity(vehid,x, y, z);

        if (x >= 0.0) x += 30.0;
        else x -= 30.0;


        if (y >= 0.0) y += 30.0;
        else y -= 30.0;


        if (z >= 0.0) z += 30.0;
        else z -= 30.0;

        SetVehicleVelocity(vehid, x, y, z);
    }
  }

  return 1;
}

You may want to remove the addition/subtraction of z. If you don't remove it you will get a falling boost/rise also (allowing people to defy gravity!)

nothing wrong now Simon! Thakns

But now I tested it. My results (in coords)

Start Pos. -> X = 0 | Y = 0 | Z = 1.2

After 3 secs of clicking LMB. -> X = 1327.89 | Y = 1321.83 | Z = 1161.80

Heh. Over power much? lol

Re: [Help] Simple Speed Boost when you press KEY_FIRE - Simon - 13.06.2010

Hah, I kinda suspected that. You'll probably want to change the 30.0 to something like 1.0-5.0 then

That will allow you to speedboost even if you are a passenger in a vehicle. Swap IsPlayerInAnyVehicle with if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER). That will ensure only the vehicle's driver can speedboost.

I have a simple sys like this in my GM but its a little different, I use GetXYForwardVelocity(i edited GetXYInFrontOfPlayer)

Re: [Help] Simple Speed Boost when you press KEY_FIRE - Kar - 13.06.2010

to much boost how to make it smaller

Re: [Help] Simple Speed Boost when you press KEY_FIRE - DJDhan - 13.06.2010

I added the do-while loop so that the velocity remain below 200 and you don't reach the speed of light when you use the boost.

Velocity of 200 is already very close to speed of light

You can also try this:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
        if(newkeys & KEY_FIRE)
        {
            new vehicleid = GetPlayerVehicleID(playerid);
            new Float:angle;
            GetVehicleZAngle(vehicleid, angle);

            new Float:velox, Float:veloy, Float:veloz;
            GetVehicleVelocity(vehicleid, velox, veloy, veloz);

            velox += floatsin(-angle, degrees);
            veloy += floatcos(-angle, degrees);
            SetVehicleVelocity(vehicleid, velox, veloy, veloz);
        }
    }
    return 1;
}

            new Float:velox, Float:veloy, Float:veloz;
            GetVehicleVelocity(vehicleid, velox, veloy, veloz);

            velox += floatsin(-angle, degrees);
            veloy += floatcos(-angle, degrees);
            SetVehicleVelocity(vehicleid, velox, veloy, veloz);
        }
    }
    return 1;
}

Thanks I'll try that.
