Hello, guys!

I'm creating a mod that includes a machine. This machine has 4 slots: 2 input slots and 2 output slots.

For this machine to work, it needs two things: 2 valid items in the input slots, and it requires that the player clicks on the "uncraft" button in the center of the GUI. Then the progress will start.

However, I'm not able to make the block entity understand that the button was clicked on the client side.

Does anybody know how to implement a GUI button that updates a block entity variable?
This is my project: https://github.com/jujulioed/Dukas_Utilities_Mod (in this version, the button interaction was not implemented yet.)

You need to send a network message to the server, saying which button in which block got pressed.

https://docs.minecraftforge.net/en/latest/networking/

There is no real standard for this, you will need to look at other mods if you want example code, e.g.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

      Crash when starting server

      By Prins_Ed · Posted

      I have created a very simple mod that is just supposed to send a message to a player when they join. Upon adding it to a server (that has other mods on it), the following crash message appears: [12:13:01] [main/ERROR] [minecraft/Main]: Failed to start the minecraft server net.minecraftforge.fml.LoadingFailedException: Loading errors encountered: [         Epic Mod (epicmod) has failed to load correctly §7java.lang.NoSuchMethodException: net.ed.epicmod.EpicMod.<init>() ]         at net.minecraftforge.fml.ModLoader.waitForTransition(ModLoader.java:243) ~[fmlcore-1.19.2-43.2.14.jar%23548!/:?] {}         at net.minecraftforge.fml.ModLoader.lambda$dispatchAndHandleError$24(ModLoader.java:208) ~[fmlcore-1.19.2-43.2.14.jar%23548!/:?] {}         at java.util.Optional.ifPresent(Optional.java:178) ~[?:?] {re:mixin}         at net.minecraftforge.fml.ModLoader.dispatchAndHandleError(ModLoader.java:208) ~[fmlcore-1.19.2-43.2.14.jar%23548!/:?] {}         at net.minecraftforge.fml.ModLoader.lambda$gatherAndInitializeMods$14(ModLoader.java:185) ~[fmlcore-1.19.2-43.2.14.jar%23548!/:?] {}         at java.lang.Iterable.forEach(Iterable.java:75) ~[?:?] {re:mixin,re:computing_frames}         at net.minecraftforge.fml.ModLoader.gatherAndInitializeMods(ModLoader.java:185) ~[fmlcore-1.19.2-43.2.14.jar%23548!/:?] {}         at net.minecraftforge.server.loading.ServerModLoader.load(ServerModLoader.java:32) ~[forge-1.19.2-43.2.14-universal.jar%23552!/:?] {re:classloading}         at net.minecraft.server.Main.main(Main.java:113) ~[server-1.19.2-20220805.130853-srg.jar%23547!/:?] {re:classloading,re:mixin,pl:mixin:A}         at jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:?] {}         at jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) ~[?:?] {}         at jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:?] {}         at java.lang.reflect.Method.invoke(Method.java:568) ~[?:?] {}         at net.minecraftforge.fml.loading.targets.CommonServerLaunchHandler.lambda$launchService$0(CommonServerLaunchHandler.java:29) ~[fmlloader-1.19.2-43.2.14.jar%2367!/:?] {}         at cpw.mods.modlauncher.LaunchServiceHandlerDecorator.launch(LaunchServiceHandlerDecorator.java:30) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:53) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:71) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.Launcher.run(Launcher.java:106) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.Launcher.main(Launcher.java:77) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:26) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:23) [modlauncher-10.0.8.jar%2354!/:?] {}         at cpw.mods.bootstraplauncher.BootstrapLauncher.main(BootstrapLauncher.java:141) [bootstraplauncher-1.1.2.jar:?] {} Why could this be? I have tried using the mod on another forge server with only this mod installed and it works there. Is my mod somehow interfering with other mods? MC version is 1.19.2
