ok, can somebody PLEASE EXPLAIN TO ME why the HELL are these classes "@SideOnly(Side.CLIENT)" now?

 

1)EntityFX

 

2)GUI related classes, server can't open GUI since "net.minecraft.client.gui" is involved!

 

anyone know what the hell im supposed to do then?

SideOnly means that the thing is only used on a specific side. And When you then say Side.Client, you say, that it is only used on the client side.

thanks for clearing up something i already knew. now can you please explain what i can do to get it on the right side?

 

-sorash67 || Skorpio

its not a question of moving class to the right side, its a question of NOT using them on the wrong side

my apologies, i didnt state my question right. what can i do to be able to use the functions of them on the server side? for example, i have a gui with buttons, and my item class uses these buttons to function, but im not allowed to do this on the server side! so how do i implement buttons and their uses in the server?

 

-sorash67 || Skorpio

this seems weird to me but i think what you want to do is let the client do his things and use packets to communicate information between client-server

coincidentally, i know i have to use packets somehow, but do you know how?

 

-sorash67 || Skorpio

how to use packets ? yes, will i explain this in a forge forum post? no, please use the wiki somebody already spent time making a tutorial on how to use them

i already have looked at both the wiki tutorials, at "Packet Handling" and "Advance Packet Handling", so thanks. if there's anymore of your help, i'd be thankful.

 

-sorash67 || Skorpio

well i dont mind helping but what do you need, if you know how to use packets then there shouldnt be any problem ???

i know how to send one, but how to read it is what im confused on. how can i transfer these information and receive them on the server?

 

-sorash67 || Skorpio

ahhh, ok, basicly you need to make a PacketHandler server side (register it in your main mod file)

 

 

mine looks like this

 

public class ForgeRevServerPacketHandler implements IPacketHandler {

@Override
public void onPacketData(INetworkManager manager,
		Packet250CustomPayload packet, Player player) {
                //here i do the stuff i need
}
}

btw im using a custom class for reading and writing packets  but basicly its the same as what the wiki says, and reading is the inverse of writing (OutputStream become InputStream etc)

actually ... here, my packing helping class

baiscly when you want to send a packet

 

PacketWriteStream stream = new PacketWriteStream();

stream.put(any primitive type)

PacketDispatcher.send*to whoever you want*(stream.makePacket("channel");

 

to read

PacketReadStream stream = new PacketReadStream(Packet);

int i = stream.readInt();

double b = stream.readDouble();

etc

thanks for clearing that up, but now how can i implement this so that i can use the functionality of client-side buttons on server?

 

-sorash67 || Skorpio

why do you want to use a button on server side ?

technicly you could send a packet to the client saying "hey btw do thsi"

 

check Minecraft.getMinecraft().thePlayer.currentScreen to see if this GuiScreen is of type of the gui you want to interract with and if yes cast it and call the method to simulate this button press, but thsi seems very weird to want to press a button from server side

hmm... maybe it helps if you read the topic i posted here:

http://www.minecraftforum.net/topic/1907147-forge-server-side-custom-gui-with-buttons/

 

that's the reason why im trying to get a button function on the server side!

 

-sorash67 || Skorpio

holy shit that is overcomplicate

 

just check that you are client side ...

 

if(world.isRemote){

player.openGui();

}

no actually thats not right ... can you jsut

 

 

spoiler your error trace ?

 

but the problem isnt opening the gui, its using the functions of its buttons! the error that i get when i use a button on the server is this:

Encountered an unexpected exception NoClassDefFoundError
java.lang.NoClassDefFoundError: moreores/tools/rainbow/GuiRainbowStaff
at moreores.tools.rainbow.ItemRainbowStaff.onItemRightClick(ItemRainbowStaff.java:57)

 

line 57 is this:

if(gui.mode == "lightning"){

 

look through the link i gave you to understand better what im trying to say!

 

-sorash67 || Skorpio

no actually thats not right ... can you jsut

 

 

spoiler your error trace ?

 

 

yup, i was in the middle of it!

 

-sorash67 || Skorpio

if(container.mode == "lightning"){

 

is what is in your code in the other thread, and theres no "container" anywhere

oh is it? my mistake, that was an experiment! not the code im using right now! will edit it!

 

-sorash67 || Skorpio

but if i understand correctly you want your item do shoot lightning if its in a certain mdoe and maybe other stuff in another, you should change this "mode" using the itemStack nbtTagCompound instead of tying this to a gui ...

oh god help me! ._. i have no clue how to do nbtTag stuff... can you help out? thanks

 

-sorash67 || Skorpio

You can send this "mode" (better, the guibutton id) of yours in a packet, alongside player username. The server can then change a variable in the item the given player has.
