我正在尝试制作一个 minecraft mod,但我无法弄清楚这个错误:
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:35: error: cannot fin
d symbol
par1DataOutputStream.writeByte(this.protocolVersion);
^
symbol: variable protocolVersion
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:36: error: cannot fin
d symbol
writeString(this.serverHost, par1DataOutputStream);
^
symbol: variable serverHost
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:37: error: cannot fin
d symbol
par1DataOutputStream.writeInt(this.serverPort);
^
symbol: variable serverPort
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:38: error: cannot fin
d symbol
writeString(this.username, par1DataOutputStream);
^

src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:54: error: cannot fin

return 3 + 2 * this.username.length();
^
symbol: variable username
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:62: error: cannot fin
d symbol
return this.protocolVersion;
^
symbol: variable protocolVersion
src\minecraft\net\minecraft\src\Packet2ClientProtocol.java:70: error: cannot fin
d symbol
return this.username;
^
这是我的 Packet2ClientProtocol.java:
package net.minecraft.src;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
public class Packet2ClientProtocol extends Packet
{
public Packet2ClientProtocol() {}
public void Packet2ClientProtocol(int par1, String par2Str, int par3, String par4Str)
{
int protocolVersion = par1;
String serverHost = par2Str;
int serverPort = par3;
String username = par4Str;
}
/**
* Abstract. Reads the raw packet data from the data stream.
*/
public void readPacketData(DataInputStream par1DataInputStream) throws IOException
{
int protocolVersion = par1DataInputStream.readByte();
String serverHost = readString(par1DataInputStream, 255);
int serverPort = par1DataInputStream.readInt();
String username = Info.Username;
}
/**
* Abstract. Writes the raw packet data to the data stream.
*/
public void writePacketData(DataOutputStream par1DataOutputStream) throws IOException
{
par1DataOutputStream.writeByte(this.protocolVersion);
writeString(this.serverHost, par1DataOutputStream);
par1DataOutputStream.writeInt(this.serverPort);
writeString(this.username, par1DataOutputStream);
}
/**
* Passes this Packet on to the NetHandler for processing.
*/
public void processPacket(NetHandler par1NetHandler)
{
par1NetHandler.handleClientProtocol(this);
}
/**
* Abstract. Return the size of the packet (not counting the header).
*/
public int getPacketSize()
{
return 3 + 2 * this.username.length();
}
/**
* Returns the protocol version.
*/
public int getProtocolVersion()
{
return this.protocolVersion;
}
/**
* Returns the username.
*/
public String getUsername()
{
return this.username;
}
}
我在这方面做错了什么?我确定我拼写正确,是我忘记了什么吗?
