Dio skripte:

C:\Users\User\Desktop\BEZE\pawno\include\JunkBuster.inc(201) : error 059: function argument may not have a default value (variable "get3d")
C:\Users\User\Desktop\BEZE\gamemodes\LSRP.pwn(103570) : error 025: function heading differs from prototype

C:\Users\User\Desktop\BEZE\gamemodes\LSRP.pwn(103572) : error 021: symbol already defined: "JBC_GetPlayerSpeed"

Evo i linije na kojima izbacuje

forward GetPlayerSpeed(playerid,get3d);
public GetPlayerSpeed(playerid, get3d)
{
	new Float: x, Float: y, Float: z;
	if (IsPlayerInAnyVehicle (playerid))
		GetVehicleVelocity (GetPlayerVehicleID (playerid), x, y, z);
	else
		GetPlayerVelocity (playerid, x, y, z);

	return 1;
}
