Thanks for your answer! I'm new to modding, I still don't know how to do that in JSON files, Could you expain it in more detail?

I created a custom button like this: public class CWButton extends BlockButtonWood { private final String name = "Transfer Button"; protected CWButton() { super(); GameRegistry.registerBlock(this, name); this.setUnlocalizedName(name); this.setCreativeTab(CreativeTabs.tabBlock); } } How can i do to make CWButton extend the texture of BlockButtonWood?

I added a button on the main menu. When player clicks that button, i want a certain world to be loaded. Here is my code to load world: GuiButton playButton = new GuiButton(id, xPosition, yPosition, width, height, "play"){ @Override public void mouseReleased(int p_146118_1_, int p_146118_2_){ String name = "My World"; Settings.mc.launchIntegratedServer(name, name, null); Settings.mc.setIngameFocus(); } }; I got this error: java.lang.NullPointerException: Unexpected error at net.minecraft.client.network.NetHandlerPlayClient.handleJoinGame(NetHandlerPlayClient.java:275) at net.minecraft.network.play.server.S01PacketJoinGame.processPacket(S01PacketJoinGame.java:84) at net.minecraft.network.play.server.S01PacketJoinGame.processPacket(S01PacketJoinGame.java:142) at net.minecraft.network.NetworkManager.processReceivedPackets(NetworkManager.java:241) at net.minecraft.client.Minecraft.runTick(Minecraft.java:2152) at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1039) at net.minecraft.client.Minecraft.run(Minecraft.java:962) at net.minecraft.client.main.Main.main(Main.java:164) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) at net.minecraftforge.gradle.GradleStartCommon.launch(Unknown Source) at GradleStart.main(Unknown Source) It seems i cannot simpily use launchIntegratedServer() to load a world successfully. What is the right way?
