Ok, I have updated IntelliJ, but now when I try to run the runClient configuration I get: Invalid value: -1 On: prepareRunClient

I used the Introduction here: https://mcforge.readthedocs.io/en/1.18.x/gettingstarted/ My IntelliJ Version is 2019.1

Hi, im setting up a mod in 1.18.2, but when i try to launch the Minecraft Client im getting this error: Exception in thread "main" java.lang.reflect.InaccessibleObjectException: Unable to make public static void cpw.mods.bootstraplauncher.BootstrapLauncher.main(java.lang.String[]) accessible: module cpw.mods.bootstraplauncher does not "exports cpw.mods.bootstraplauncher" to unnamed module @726f3b58 at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:354) at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:297) at java.base/java.lang.reflect.Method.checkCanSetAccessible(Method.java:199) at java.base/java.lang.reflect.Method.setAccessible(Method.java:193) at com.intellij.rt.execution.application.AppMainV2.main(AppMainV2.java:130) Anyone can help me?

Hi, I was following the 1.18.2 minecraft modding introduction, and when I import the build.gradle file to IntelliJ, I get this warning: Warning:<i><b>root project 'TikTokMod': Unable to build MinecraftDev MCP project configuration</b> Details: groovy.lang.MissingPropertyException: Could not get unknown property 'genSrgs' for task set of type org.gradle.api.internal.tasks.DefaultTaskContainer.</i> plus it doesn't detect any tasks for setting up my mod. How can I solve the problem?

Ok so, i changed the entity in this way: public class SmokeBulletEntity extends DamagingProjectileEntity implements IRendersAsItem { private static final DataParameter<Boolean> ACTIVATED = EntityDataManager.defineId(SmokeBulletEntity.class, DataSerializers.BOOLEAN); private static final ItemStack STACK = new ItemStack(ModItems.BULLET.get()); private int duration; public SmokeBulletEntity(World world) { super(ModEntities.SMOKE_BULLET.get(), world); } @Override public ItemStack getItem() { return STACK; } @Override protected void onHitBlock(BlockRayTraceResult rayTraceResult) { if (this.isActivated()) return; if (!this.level.isClientSide) { this.activate(); } super.onHitBlock(rayTraceResult); } @Override protected void onHitEntity(EntityRayTraceResult entityRayTraceResult) { //Must be Empty } private void activate() { this.setActivated(true); this.duration = 200; this.setDeltaMovement(0, 0, 0); this.xPower = 0; this.yPower = 0; this.zPower = 0; System.out.println("Active Smoke Projectile"); } @Override public void tick() { if (this.isActivated()) { for (int i = 0; i < 100; i++) { this.level.addParticle(ParticleTypes.FLAME, this.getX(), this.getY() + i, this.getZ(), 0, 0, 0); } this.duration--; if (this.duration <= 0) { this.remove(); } } else { super.tick(); } } @Override public void addAdditionalSaveData(CompoundNBT nbt) { super.addAdditionalSaveData(nbt); nbt.putBoolean("activated", this.isActivated()); nbt.putInt("duration", this.duration); } @Override protected void defineSynchedData() { super.defineSynchedData(); this.entityData.set(ACTIVATED, false); } public void setActivated(boolean activated) { this.entityData.set(ACTIVATED, activated); } public boolean isActivated() { return this.entityData.get(ACTIVATED); } @Override public EntityDataManager getEntityData() { return super.getEntityData(); } @Override public void readAdditionalSaveData(CompoundNBT nbt) { super.readAdditionalSaveData(nbt); if (nbt.contains("activated")) { this.setActivated(nbt.getBoolean("activated")); } if (nbt.contains("duration")) { this.duration = nbt.getInt("duration"); } } @Override public IPacket<?> getAddEntityPacket() { return NetworkHooks.getEntitySpawningPacket(this); } } But now, when i spawn it i encounter this error: [15:39:10] [Server thread/FATAL] [minecraft/ThreadTaskExecutor]: Error executing task on Server java.lang.NullPointerException: null at net.minecraft.network.datasync.EntityDataManager.set(EntityDataManager.java:122) ~[forge:?] {re:classloading} at com.ike.gunmod.entity.SmokeBulletEntity.defineSynchedData(SmokeBulletEntity.java:93) ~[?:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.entity.Entity.<init>(Entity.java:216) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.projectile.ProjectileEntity.<init>(ProjectileEntity.java:25) ~[forge:?] {re:classloading} at net.minecraft.entity.projectile.DamagingProjectileEntity.<init>(DamagingProjectileEntity.java:26) ~[forge:?] {re:classloading} at com.ike.gunmod.entity.SmokeBulletEntity.<init>(SmokeBulletEntity.java:35) ~[?:?] {re:classloading,pl:runtimedistcleaner:A} at com.ike.gunmod.item.gun.SmokeGunItem.getBullet(SmokeGunItem.java:32) ~[?:?] {re:classloading} at com.ike.gunmod.item.gun.AbstractGunItem.use(AbstractGunItem.java:42) ~[?:?] {re:classloading} at net.minecraft.item.ItemStack.use(ItemStack.java:217) ~[forge:?] {re:classloading,xf:fml:forge:filled_map.4,xf:fml:forge:itemstack} at net.minecraft.server.management.PlayerInteractionManager.useItem(PlayerInteractionManager.java:287) ~[forge:?] {re:classloading} at net.minecraft.network.play.ServerPlayNetHandler.handleUseItem(ServerPlayNetHandler.java:982) ~[forge:?] {re:classloading} at net.minecraft.network.play.client.CPlayerTryUseItemPacket.handle(CPlayerTryUseItemPacket.java:28) ~[forge:?] {re:classloading} at net.minecraft.network.play.client.CPlayerTryUseItemPacket.handle(CPlayerTryUseItemPacket.java:9) ~[forge:?] {re:classloading} at net.minecraft.network.PacketThreadUtil.lambda$ensureRunningOnSameThread$0(PacketThreadUtil.java:19) ~[forge:?] {re:classloading} at net.minecraft.util.concurrent.TickDelayedTask.run(TickDelayedTask.java:17) ~[forge:?] {re:classloading} at net.minecraft.util.concurrent.ThreadTaskExecutor.doRunTask(ThreadTaskExecutor.java:136) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.util.concurrent.RecursiveEventLoop.doRunTask(RecursiveEventLoop.java:22) ~[forge:?] {re:classloading} at net.minecraft.server.MinecraftServer.doRunTask(MinecraftServer.java:734) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.doRunTask(MinecraftServer.java:159) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.util.concurrent.ThreadTaskExecutor.pollTask(ThreadTaskExecutor.java:109) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.pollTaskInternal(MinecraftServer.java:717) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.pollTask(MinecraftServer.java:711) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.util.concurrent.ThreadTaskExecutor.managedBlock(ThreadTaskExecutor.java:119) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.waitUntilNextTick(MinecraftServer.java:697) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.runServer(MinecraftServer.java:646) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.lambda$spin$0(MinecraftServer.java:232) ~[forge:?] {re:classloading,pl:accesstransformer:B} at java.lang.Thread.run(Thread.java:748) [?:1.8.0_231] {} Why this happen?

How can i set the data on the client side? The methods Entity#addAdditionalSaveData and Entity#readAdditionalSaveData doesn't do that?

Ok so, i changed the function Entity#tick public void tick() { if (this.activated) { for (int i = 0; i < 100; i++) { this.level.addParticle(ParticleTypes.FLAME, this.getX(), this.getY() + i, this.getZ(), 0, 0, 0); } this.duration--; if (this.duration <= 0) { this.remove(); } } else { super.tick(); } } But still the bullet does not show the particles. There are only those of the basic bullet: Why this happen?

Ok, so where do i put the code for spawning particle?

Hi! I was trying to create a smoke projectile, that when hits the ground spawn some particles for a certain duration. The problem is that, when the entity hits the ground, it don't spawn the particles at all. Here is my projectile: @OnlyIn(value = Dist.CLIENT, _interface = IRendersAsItem.class) public class SmokeBulletEntity extends DamagingProjectileEntity implements IRendersAsItem { private static final ItemStack STACK = new ItemStack(ModItems.BULLET.get()); private boolean activated; private int duration; public SmokeBulletEntity(World world) { super(ModEntities.SMOKE_BULLET.get(), world); this.activated = false; } @Override public ItemStack getItem() { return STACK; } @Override protected void onHitBlock(BlockRayTraceResult rayTraceResult) { if (this.activated) return; if (!this.level.isClientSide) { this.activate(); } super.onHitBlock(rayTraceResult); } @Override protected void onHitEntity(EntityRayTraceResult entityRayTraceResult) { //Must be Empty } private void activate() { this.activated = true; this.duration = 200; this.setDeltaMovement(0, 0, 0); this.xPower = 0; this.yPower = 0; this.zPower = 0; System.out.println("Active Smoke Projectile"); } @Override public void tick() { if (this.activated && !this.level.isClientSide) { //System.out.println(String.format("%f, %f, %f", this.getX(), this.getY(), this.getZ())); for (int i = 0; i < 100; i++) { this.level.addParticle(ParticleTypes.FLAME, this.getX(), this.getY() + i, this.getZ(), 0, 0, 0); } this.duration--; if (this.duration <= 0) { this.remove(); } } else { super.tick(); } } @Override public void addAdditionalSaveData(CompoundNBT nbt) { super.addAdditionalSaveData(nbt); nbt.putBoolean("activated", this.activated); nbt.putInt("duration", this.duration); } @Override public void readAdditionalSaveData(CompoundNBT nbt) { super.readAdditionalSaveData(nbt); if (nbt.contains("activated")) { this.activated = nbt.getBoolean("activated"); } if (nbt.contains("duration")) { this.duration = nbt.getInt("duration"); } } @Override public IPacket<?> getAddEntityPacket() { return NetworkHooks.getEntitySpawningPacket(this); } } Can somebody explain me why? Thanks!

Ah ok, it has a different name. Thanks!

Oh, I need to register the Effect? Not finding the EFFECT tag in ForgeRegistries I thought I shouldn't register them. How can I register an effect?

Hi! I was trying to reate a custom effect, and it works properly except for a little thing. When im on the Inventory of the Player, it doesn't render at all, how can i do? I see that there is a method called "renderHUDEffect(...)", but i don't know how to use it. Someone can help me? This is my Effect Class: public class ColorEffect extends Effect { private final String colorName; private final String descriptionId; public ColorEffect(String colorName, int color) { super(EffectType.HARMFUL, color); this.colorName = colorName; this.descriptionId = "color.effect." + colorName; } @Override public void applyEffectTick(LivingEntity entity, int amplifier) { if (entity instanceof PlayerEntity) { PlayerEntity player = (PlayerEntity) entity; if (amplifier <= 0) { player.removeEffect(this); return; } player.causeFoodExhaustion(0.5f); player.addEffect(new EffectInstance(this, 2000, amplifier)); } } @Override public boolean isDurationEffectTick(int duration, int amplifier) { return true; } public String getColorName() { return colorName; } @Override public ITextComponent getDisplayName() { return new TranslationTextComponent("colorfood.effect." + this.colorName); } public String getOrCreateDescriptionId() { return this.descriptionId; } } Thanks!

Thanks a lot!

Hi! I wandering if there is a way to change the behavior of the minecraft vanilla mob. My idea is to add a bed for the cat, and when the cat is damaged or he simply wants to sleep, goes into the bed. There is a way to add this behavior to the vanilla cat?

Oh thanks, now it works properly
