I'm trying to allow the player to call up a gui from a book, by method of ItemRightclick, but I'm not sure what's wrong. I have all of my items in one class for their unlocalized names, so I think that's part of the problem, though I thought there should be a way to have them all call up the same gui.

 

 

My class file for the gui.

package guis;

 

import lib.RefStrings;

 

import org.lwjgl.opengl.GL11;

 

import net.minecraft.client.gui.GuiScreen;

import net.minecraft.util.ResourceLocation;

 

public class CoreGuideGui extends GuiScreen {

//Change the height to ideal length later

int guiWidth = 150;

int guiHeight= 150;

 

@Override

public void drawScreen(int x, int y, float ticks) {

int guiX = (width - guiWidth)/2;

int guiY = (height - guiHeight)/2;

//Changes color, this is optional. If I can figure out how to make one gui, then change all their colors, use this. If not, remove it.

GL11.glColor4f(1,1,1,1);

//May be an issue here, but this is supposed to obtain the image for my gui.

mc.renderEngine.bindTexture(new ResourceLocation(RefStrings.MODID, "textures/gui/testgui.png"));

drawTexturedModalRect(guiX, guiY, 0, 0, guiWidth, guiHeight);

super.drawScreen(x, y, ticks);

}

}

 

My code inside my Item class

 

 

public  ItemStack onItemRightClick(ItemStack item, World world, EntityPlayer player){

if(!world.isRemote){

Minecraft.getMinecraft().displayGuiScreen(new CoreGuideGui());

}

return onItemRightClick(item, world, player);

}

 

 

Okay, I removed the "!", but I'm not seeing what causes an infinite loop.

Ohhhhhh, I forgot super! Thanks, I'll make those changes and see if that fixes it.

Okay, I'll admit I'm still unsure as to how to get the Minecraft class to run though the client class. Should I just insert my code into my clientproxy class, or make a new class entirely?

 

public  ItemStack onItemRightClick(ItemStack item, World world, EntityPlayer player){

if(world.isRemote){

  Minecraft.getMinecraft().displayGuiScreen(new CoreGuideGui());

}

return super.onItemRightClick(item, world, player);

}

 

 

Here's what it currently looks like.

@SideOnly(Side.CLIENT)

public  ItemStack onItemRightClick(ItemStack item, World world, EntityPlayer player){

if(world.isRemote){

  Minecraft.getMinecraft().displayGuiScreen(new CoreGuideGui());

}

return null;

 

 

Alright, I added the @SideOnly, but I'm still not getting the desired results. Is there a mistake elsewhere that I need to fix?

You can't use direct call to Minecraft class, because it has annotation @SideOnly(Side.CLIENT), meaning that Minecraft class is not packed during compilation with dedicated server, so if you even try to reference it, even if you don't use it on server (with world.isRemote condition), dedicated server will crash with java.lang.classnotfoundexception, because that class don't even exists.

 

So, you have to call it through SidedProxy.

 

Something like this:

public class CommonProxy {

public void displayGui(short guiId) {
	//NO-OP
}

}

 

public class ClientProxy extends CommonProxy {

@Override
public void displayGui(short guiId) {
	switch(guiId) {
                	case 0: Minecraft.getMinecraft().displayGuiScreen(new GuiTest()); break;
                }
        }

}

 

Edit: Fixed the code, thanks to diesieben07 for pointing to my mistake

Yeah, right. GuiScreen is Client-Sided too.

 

But that could be solved it by using enum or numerical IDs.
