[1.8]make minecraft to wen press the key Multiply put this item in my inventory


Recommended Posts

well good nigths


i been create a keybind class and works now i wanna use that keybind to do something


i set the key.MULTIPLY  i want to put in mi inventory an item when this key is pressed but not know how

to achive this, i think i must use packages so alredy have a funtional package handler  and do this


keybind.MULTIPLY > gearbox.class > packageToserver.class > executeCustonClassThatputTheitemInInventory.


in efect i hit multiply and have the item created in inventory but just in the local world so it behaves wrong and can disapear i any moment or is there but dont works .



these are just conjuteras whit code and has become long am clumsy like to put here the classes involved

soo i gona leave it as a simple question for now

how you would do for at pressing particular key on the keyboard will spawn a particular item in inventory

the troube is that the code end being execute in the local world only


but there is like seven clases involving sending from one to other but this is the one launchiing the package to execute remotly and execute the code localy to


the keybind trigers this in the gearbox class


public static void liberar0() {

    Mercenary.network.sendToServer(new mensajeMercenarioalServidor("liberar"));//execute in server 
    mercenarymod.mensajes.ejecutar.esto("liberar"); //execute here localy



the server handler0 catch the message and do this


public IMessage onMessage(mensajeMercenarioalServidor message, MessageContext ctx) {
    	//System.out.println(String.format("Received %s from %s", message, ctx.getServerHandler().playerEntity.getDisplayName()));
    	System.out.println("### Mensaje en el Servidor="+texto0);
    	ejecutar.esto(texto0); //execute this aparently in the server world 


ihave this in console , and i assume it means the server is geting the message


[21:32:32] [Netty Server IO #1/INFO] [sTDOUT]: [mercenarymod.mensajes.mensajeMercenarioalServidor$Handler0:onMessage:65]: ### Mensaje en el Servidor=liberar

[21:32:32] [Netty Server IO #1/INFO]: [CHAT] §3mundo=true




lastly the ejecutar class have this


public static void esto(String comando){

Minecraft mc = Minecraft.getMinecraft();
EntityPlayer playerIn= mc.thePlayer;
World mundo=playerIn.getEntityWorld();

chat.chatda(playerIn, "mundo="+mundo.isRemote);

ItemStack objetoprueba = new ItemStack(MercenaryModItems.camaEl,1,0);

playerIn.inventory.setInventorySlotContents(8, objetoprueba);





the chat.chatda(playerIn, "mundo="+mundo.isRemote); apears 2 times in the screen and say two times



that means the code is executed two times but just local world , i get the item in inventory but behaves wrong becose is not synced whit server

well now i have something

and is working

but im afraid to crash a server because i have done


keybind > gearbox > sendtoservercomad > sendToLocalcomand


i wann reduce the need of code in the event of trigering the accion put in my invetory

so in gearbox now i just execute



public static void liberar0() {
            System.out.println("\n\n\n=============liberar=true;============"); //just to mark whent it start this code in the console

    Mercenary.network.sendToServer(new mensajeMercenarioalServidor("liberar"));


notece i just send the packge to server  im not executing the class ejecutar.java from here


in the Server handler i do this

i execute  ejecutar.esto() and resend the mesage from here to the local world

System.out.println("Mensaje en el Servidor="+texto0);
    	EntityPlayer playerIn=ctx.getServerHandler().playerEntity;  //method taken from  diesieben07 
    	EntityPlayerMP playerMp=(EntityPlayerMP)playerIn;
    	World mundo=playerIn.getEntityWorld();
    	chat.chatda(playerIn, "in server mundo="+mundo.isRemote);
    	Mercenary.network.sendTo(new mensajeMercenarioalMundoLocal("texto0"),playerMp);


in the ClientHandler ido this and here is mi fear gets a craddle

    public IMessage onMessage(mensajeMercenarioalMundoLocal message, MessageContext ctx) {
    	Minecraft mc = Minecraft.getMinecraft();
    	EntityPlayer playerIn= mc.thePlayer;
    	//EntityPlayer playerIn=ctx.getServerHandler().playerEntity;
    	//EntityPlayerMP playerMp=(EntityPlayerMP)playerIn;
    	World mundo=playerIn.getEntityWorld();
    	chat.chatda(playerIn, "in local mundo="+mundo.isRemote);

    	return null; // no response in this case


a have ended using Minecraft mc = Minecraft.getMinecraft(); to get the user but alredy told me that this could crash the server but here is no server here is the client

so is teoricaly safe  is this true or i have to find other way to get server , idont wanna include playerIn.getUnlocalizatedName in the mesage coz i read there is a limit of 16 characters and i gonna use thath to make this code do a lot of diferent things 


EntityPlayer playerIn=ctx.getServerHandler().playerEntity; dont works here and dont find equivalent

EntityPlayer playerIn=ctx.getClientHandler().playerEntity;



for this code, is working rigth no crash no errors on player screen i have


in local mundo=true

ejecutar mundo=true

in server mundo=false

ejecutar mundo=false


in console i have
