Hi, I'm begginer forge developer.

 

  I want, right click at glass block, then show custom GUI to user.

 

  First, I made EventHookContainerClass,

  @ForgeSubscribe

public void onPlayerInteract(PlayerEvent event) {

System.out.println(event.entityPlayer);

        }

  But, this is only response, living thing. Not block.

 

  So, I modified glass block that I want interaction block.

  Original glass block is common/net.minecraft.src, And I override onBlockActivated method, like this.

@Override

public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9) {

Minecraft mc = ModLoader.getMinecraftInstance();

mc.displayGuiScreen(new GuiOptions(mc.currentScreen, mc.gameSettings));

        }

 

  This code is work at client. But not a server. Server's log is this.
