+ | ====== Using the Information of the ExtendedScreenHandler in our Screen ====== | ||
+ | |||
+ | <code java [enable_line_numbers=" | ||
+ | |||
+ | public class BoxScreen extends HandledScreen< | ||
+ | private static final Identifier TEXTURE = new Identifier(" | ||
+ | |||
+ | public BoxScreen(ScreenHandler handler, PlayerInventory inventory, Text title) { | ||
+ | super(handler, | ||
+ | //We try to get the block position to use it as our title, if that fails for some reason we will use the default title | ||
+ | } | ||
+ | |||
+ | //This method will try to get the Position from the ScreenHandler, | ||
+ | //get the ScreenHandler instance here which has the correct BlockPos in it! | ||
+ | private static Optional< | ||
+ | if (handler instanceof BoxScreenHandler) { | ||
+ | BlockPos pos = ((BoxScreenHandler) handler).getPos(); | ||
+ | return pos != null ? Optional.of(new LiteralText(" | ||
+ | } else { | ||
+ | return Optional.empty(); | ||
+ | } | ||
+ | } | ||
+ | |||
+ | |||
+ | @Override | ||
+ | protected void drawBackground(MatrixStack matrices, float delta, int mouseX, int mouseY) { [...] } | ||
+ | |||
+ | @Override | ||
+ | public void render(MatrixStack matrices, int mouseX, int mouseY, float delta) { [...] } | ||
+ | |||
+ | @Override | ||
+ | protected void init() { [...] } | ||
+ | } | ||
+ | |||
+ | </ | ||
+ | |||
+ | ====== Registering our ScreenHandler ====== | ||
+ | |||
+ | <code java [enable_line_numbers=" | ||
+ | public class ExampleMod implements ModInitializer { | ||
+ | |||
+ | [...] | ||
+ | public static final ScreenHandlerType< | ||
+ | |||
+ | static { | ||
+ | [...] | ||
+ | |||
+ | //we now use registerExtended as our screenHandler now accepts a packetByteBuf in its Constructor | ||
+ | BOX_SCREEN_HANDLER = ScreenHandlerRegistry.registerExtended(BOX, | ||
+ | } | ||
+ | |||
+ | @Override | ||
+ | public void onInitialize() { | ||
+ | |||
+ | } | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | ====== Result ====== | ||
+ | You have now seen how to transfer data when the ScreenHandler is opened. In the image you can see the result: The Blocks title is now the block position. Do note that this is just a demonstration, | ||
+ | Setting the position as the title would be possible alot easier. | ||
+ | |||
+ | You might wonder: Can i transfer this data again even after the Screen was opened? | ||
+ | This is possible by sending custom Packets (see: [[tutorial: | ||
+ | You might also want to have a look at the BlockEntityClientSerializable Interface from the Fabric API. | ||
+ | |||
+ | If you only want to sync integer values you can use PropertyDelegates SEE MY NEXT TUTROIAL | ||
