Hi guys, im trying to use the setBlock command to place the active (giving out redstone power) version of my keypad if the code you type in the keypad GUI is correct. The code im about to show you works flawlessly on the client (Singleplayer) side, but not on the server (Multiplayer) side. Heres the code:
BlockKeypad 'onBlockActivated' code:
this.playerObj = par5EntityPlayer;
this.lastKeypadX = par2;
this.lastKeypadY = par3;
this.lastKeypadZ = par4;
if(par1World instanceof WorldServer){
this.worldServerObj = par1World;
TileEntityKeypad TEK = (TileEntityKeypad) par1World.getBlockTileEntity(par2, par3, par4);
System.out.println(TEK.getKeypadCode() + " | Code from TileEntity");
this.openCode = TEK.getKeypadCode();
if(TEK.getKeypadCode() == 0){
par5EntityPlayer.openGui(mod_SecurityCraft.instance, 1, par1World, par2, par3, par4);
}else{
par5EntityPlayer.openGui(mod_SecurityCraft.instance, 0, par1World, par2, par3, par4);
}
return true;
}else{
this.worldObj = par1World;
//Rest of client code here
return true;
}
}
GuiKeypad code:
private void checkCode(String par1String) {
int code = 0;
try{
code = Integer.parseInt(par1String);
}catch(Exception e){
e.printStackTrace();
}
System.out.println(BlockKeypad.openCode + " | GUI");
if(code == BlockKeypad.openCode){
new ScheduleUpdate(3, BlockKeypad.worldServerObj, BlockKeypad.lastKeypadX,BlockKeypad.lastKeypadY, BlockKeypad.lastKeypadZ, BlockKeypad.openCode, this.keypadInventory);
BlockKeypad.playerObj.closeScreen();
}
}
ScheduleUpdate class:
public class ScheduleUpdate{
Timer timer;
private int xCoord;
private int yCoord;
private int zCoord;
private int metadata;
private int passcode;
private TileEntityKeypad TEK;
public ScheduleUpdate(int seconds, World par2World, int par3, int par4, int par5, int par6, TileEntityKeypad keypadInventory){
timer = new Timer();
timer.schedule(new RemindTask(), seconds*1000); //TODO 60
xCoord = par3;
yCoord = par4;
zCoord = par5;
passcode = par6;
TEK = keypadInventory;
//BlockKeypad.shouldCheckMeta = false;
metadata = par2World.getBlockMetadata(par3, par4 , par5);
System.out.println(metadata + " | metadata");
par2World.setBlock(par3, par4, par5, mod_SecurityCraft.KeypadActive.blockID, metadata, 3);
par2World.notifyBlocksOfNeighborChange(par3, par4 , par5, mod_SecurityCraft.KeypadActive.blockID);
}
class RemindTask extends TimerTask{
public void run(){
BlockKeypad.worldObj.setBlock(xCoord, yCoord, zCoord, mod_SecurityCraft.Keypad.blockID, metadata, 3);
BlockKeypad.worldObj.notifyBlocksOfNeighborChange(xCoord, yCoord, zCoord, mod_SecurityCraft.Keypad.blockID);
((TileEntityKeypad) BlockKeypad.worldObj.getBlockTileEntity(xCoord, yCoord, zCoord)).setKeypadCode(passcode);
timer.cancel();
}
}
}
If i use this code i have now, for some reason, it gives me a NullPointerException on BlockKeypad.worldServerObj when i create a new ScheduleUpdate object (in the GuiKeypad code). If i switch that with BlockKeypad.worldObj (my client side World object), it looks like it places the block, but if i update the new block (right-clicking it, placing a block next to it, etc. ), it disappears. So im guessing i have to use the worldServerObj, but again, it throws a NullPointerException whenever i try and use that, even though im setting to the server's World object before the GUI even opens.
I made a item to System.out.println() the two world objects i made in the BlockKeypad class.
When i right-click it, it prints this in the console (client):
net.minecraft.multiplayer.WorldClient()
null
In the server console:
null
net.minecraft.multiplayer.WorldServer()
Anyone know whats wrong? I would greatly appreciate any help at all, as this is the only thing holding me back from releasing the SMP-compatible version of my mod. Thanks!
