Where do you use .setInventorySlotContents(int slot, ItemStack itemstack) ?

Thank you, but that's too deep for me :'(. I found another solution. I created a Dummy Container which displays the GUI. Now I cant use GuiScreen but it works.

Changes: GuiHandler }else if(ID == 100){ System.out.println("GuiHandler: getServerGuiElement ID == 100 called"); return null; } Command @SideOnly(Side.CLIENT) public void processCommand(ICommandSender commandSender, String[] strArray){ int i; WorldServer worldserver = MinecraftServer.getServer().worldServers[1]; commandSender.addChatMessage(new ChatComponentTranslation("commands.main.heading", new Object[0])); EntityPlayer p = (EntityPlayer)commandSender; World w = p.getEntityWorld(); ChunkCoordinates c = commandSender.getPlayerCoordinates(); int x = c.posX; int y = c.posY; int z = c.posZ; System.out.println("CommandMain.java: call GUI"); if(w.isRemote){ System.out.println("CommandMain.java:CLIENT - World is remote"); p.openGui(Main.instance, 100, w, x, y, z); }else{ System.out.println("CommandMain.java:SERVER - World is not remote"); } System.out.println("CommandMain.java: done"); } But it doesnt work. Console output: CommandMain.java: call GUI CommandMain.java:SERVER - World is not remote CommandMain.java: done

Hello, I want to make a simple GUI and I want to open this GUI with a command. The GUI should only display a "Help" with icons (Blocks and Items) and text (Description) but that's not my problem. I cant open the GUI. Whenever I run the command I get an error. [server thread/ERROR]: Couldn't process command: 'mycommand' java.lang.ClassCastException: tk.MyName.MyMod.gui.GuiHelp cannot be cast to net.minecraft.inventory.Container Command Class: public class CommandMain extends CommandBase { protected Minecraft mc; public String getCommandName(){ return "mycommand"; } /** * Return the required permission level for this command. */ public int getRequiredPermissionLevel(){ return 0; } /** * Return the required permission level for this command. */ public String getCommandUsage(ICommandSender commandSender){ return "Usage"; } public void processCommand(ICommandSender commandSender, String[] strArray){ int i; WorldServer worldserver = MinecraftServer.getServer().worldServers[1]; commandSender.addChatMessage(new ChatComponentTranslation("commands.main.heading", new Object[0])); EntityPlayer p = (EntityPlayer)commandSender; World w = p.getEntityWorld(); ChunkCoordinates c = commandSender.getPlayerCoordinates(); int x = c.posX; int y = c.posY; int z = c.posZ; System.out.println("CommandMain.java: call GUI"); p.openGui(Main.instance, 100, w, x, y, z); System.out.println("CommandMain.java: done"); } } GuiHandler Class: public class GuiHandler implements IGuiHandler{ public GuiHandler (){ } @Override public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) { if(ID == 0){ --- }else if(ID == 1){ --- }else if(ID == 100){ System.out.println("GuiHandler: getClientGuiElement ID == 100 called"); return new GuiHelp(player); } return null; } @Override public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) { if(ID == 0){ --- }else if(ID == 1){ --- }else if(ID == 100){ System.out.println("GuiHandler: getServerGuiElement ID == 100 called"); return new GuiHelp(player); } return null; } } Gui Class: (its a modified copy of the DemoGui) @SideOnly(Side.CLIENT) public class GuiHelp extends GuiScreen{ private static final Logger logger = LogManager.getLogger(); private static final ResourceLocation field_146348_f = new ResourceLocation("textures/gui/demo_background.png"); public GuiHelp(EntityPlayer player){ } @Override public boolean doesGuiPauseGame() { return false; } /** * Adds the buttons (and other controls) to the screen in question. */ public void initGui() { this.buttonList.clear(); byte b0 = -16; this.buttonList.add(new GuiButton(1, this.width / 2 - 116, this.height / 2 + 62 + b0, 114, 20, I18n.format("gui.help.ok", new Object[0]))); } protected void actionPerformed(GuiButton button) { switch (button.id) { case 1: button.enabled = false; this.mc.displayGuiScreen((GuiScreen)null); this.mc.setIngameFocus(); } } /** * Called from the main game loop to update the screen. */ public void updateScreen() { super.updateScreen(); } /** * Draws either a gradient over the background screen (when it exists) or a flat gradient over background.png */ public void drawDefaultBackground() { super.drawDefaultBackground(); GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F); this.mc.getTextureManager().bindTexture(field_146348_f); int i = (this.width - 248) / 2; int j = (this.height - 166) / 2; this.drawTexturedModalRect(i, j, 0, 0, 248, 166); } /** * Draws the screen and all the components in it. */ public void drawScreen(int p_73863_1_, int p_73863_2_, float p_73863_3_) { this.drawDefaultBackground(); int k = (this.width - 248) / 2 + 10; int l = (this.height - 166) / 2 + 8; this.fontRendererObj.drawString(I18n.format("demo.help.title", new Object[0]), k, l, 2039583); l += 12; GameSettings gamesettings = this.mc.gameSettings; this.fontRendererObj.drawString(I18n.format("demo.help.movementShort", new Object[] {GameSettings.getKeyDisplayString(gamesettings.keyBindForward.getKeyCode()), GameSettings.getKeyDisplayString(gamesettings.keyBindLeft.getKeyCode()), GameSettings.getKeyDisplayString(gamesettings.keyBindBack.getKeyCode()), GameSettings.getKeyDisplayString(gamesettings.keyBindRight.getKeyCode())}), k, l, 5197647); this.fontRendererObj.drawString(I18n.format("demo.help.movementMouse", new Object[0]), k, l + 12, 5197647); this.fontRendererObj.drawString(I18n.format("demo.help.jump", new Object[] {GameSettings.getKeyDisplayString(gamesettings.keyBindJump.getKeyCode())}), k, l + 24, 5197647); this.fontRendererObj.drawString(I18n.format("demo.help.inventory", new Object[] {GameSettings.getKeyDisplayString(gamesettings.keyBindInventory.getKeyCode())}), k, l + 36, 5197647); this.fontRendererObj.drawSplitString(I18n.format("demo.help.fullWrapped", new Object[0]), k, l + 68, 218, 2039583); super.drawScreen(p_73863_1_, p_73863_2_, p_73863_3_); } } What am I doing wrong? I think my GuiHandler is not right.
