TreesOfStages is first listed so may there's te Problem. Try what happens after you removed it from your mod folder

Have you a log about the error? Would help to find the exact problem

Ask if something is unclear about.

So something like this never happened to me, but I can give you a common problem while trying to join with several mods: 2 or more mods conflict with each other: Try to remove one try to play with remaining It still shows you that: Put the mod in again try again with rmoving the next mod in your list If not: Congrats, you've found the conflicting mod

So with classic System.out.println(entity) i got this [11:07:49] [Server thread/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:89]: EntityPlayerMP['Player87'/318, l='Triforce Test', x=227.66, y=95.00, z=265.97] [11:07:49] [main/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:89]: null This means the code finds the Player on Serverside but not on Client, I think Then I get this [11:13:10] [main/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:89]: EntityPlayerSP['Player636'/318, l='MpServer', x=227.66, y=95.00, z=265.97] [11:13:10] [Server thread/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:89]: EntityPlayerMP['Player636'/318, l='Triforce Test', x=227.66, y=95.00, z=265.97] [11:13:10] [main/INFO] [STDOUT]: [com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head:shoot:89]: null He seems to have touble to get the normal Player.

@diesieben07 That may is right but it doesn't help me. I don't understand HOW this works, I don't want to know WHY this or the other thing is better. I've found something what might be the result of the Problem(see my post above) and hope that you guys can tell me how to solve this. Soory to be such an idiot that I don't understand what you mean with the posts above but I'm still quite new to forge and don't know much about networking. I simply tried to copy something from Vanilla and adapt to my needs what in the most cases works well.

Could anyone please tell me if the Problem results in the NPE in the error above and how to fix that. Cause I'm lost in Forge Javadoc and now completely confused. I've no idea what you mean with all this. I copied from Fishing hook as I thought the fishingrod Fishinghook relation is quite similar to the Clawshot clawshot_head relation. But I see this is quite complicated so what should I do.

I've haven't changed anything so far (except trying once with out the if(world!=remote)) because I don't have any idea what to do for example should my Entity implement the interface or the Renderer? If the Entity should: what I'm supposed to write into the methods of the interface? Same for the case the Renderer should implement it. Some example code could really help me.

So how would I use this? Also I've found an error while trying to use it (doesn't breaks the game) [13:02:45] [main/FATAL]: Error executing task java.util.concurrent.ExecutionException: java.lang.RuntimeException: A severe problem occurred during the spawning of an entity at (194.78415135238228, 74.54834158954293, 194.78415135238228) at java.util.concurrent.FutureTask.report(FutureTask.java:122) ~[?:1.8.0_152] at java.util.concurrent.FutureTask.get(FutureTask.java:192) ~[?:1.8.0_152] at net.minecraft.util.Util.runTask(SourceFile:47) [Util.class:?] at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:1086) [Minecraft.class:?] at net.minecraft.client.Minecraft.run(Minecraft.java:397) [Minecraft.class:?] at net.minecraft.client.main.Main.main(SourceFile:123) [Main.class:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_152] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_152] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_152] at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_152] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_152] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[?:1.8.0_152] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:1.8.0_152] at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_152] at net.minecraftforge.gradle.GradleStartCommon.launch(GradleStartCommon.java:97) [start/:?] at GradleStart.main(GradleStart.java:26) [start/:?] Caused by: java.lang.RuntimeException: A severe problem occurred during the spawning of an entity at (194.78415135238228, 74.54834158954293, 194.78415135238228) at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.spawnEntity(EntitySpawnHandler.java:136) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.process(EntitySpawnHandler.java:64) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.lambda$channelRead0$0(EntitySpawnHandler.java:55) ~[EntitySpawnHandler.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) ~[?:1.8.0_152] at java.util.concurrent.FutureTask.run(FutureTask.java:266) ~[?:1.8.0_152] at net.minecraft.util.Util.runTask(SourceFile:46) ~[Util.class:?] ... 15 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedConstructorAccessor60.newInstance(Unknown Source) ~[?:?] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) ~[?:1.8.0_152] at java.lang.reflect.Constructor.newInstance(Constructor.java:423) ~[?:1.8.0_152] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.spawnEntity(EntitySpawnHandler.java:88) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.process(EntitySpawnHandler.java:64) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.lambda$channelRead0$0(EntitySpawnHandler.java:55) ~[EntitySpawnHandler.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) ~[?:1.8.0_152] at java.util.concurrent.FutureTask.run(FutureTask.java:266) ~[?:1.8.0_152] at net.minecraft.util.Util.runTask(SourceFile:46) ~[Util.class:?] ... 15 more Caused by: java.lang.NullPointerException at com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head.shoot(Clawshot_Head.java:89) ~[Clawshot_Head.class:?] at com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head.<init>(Clawshot_Head.java:33) ~[Clawshot_Head.class:?] at sun.reflect.GeneratedConstructorAccessor60.newInstance(Unknown Source) ~[?:?] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) ~[?:1.8.0_152] at java.lang.reflect.Constructor.newInstance(Constructor.java:423) ~[?:1.8.0_152] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.spawnEntity(EntitySpawnHandler.java:88) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.process(EntitySpawnHandler.java:64) ~[EntitySpawnHandler.class:?] at net.minecraftforge.fml.common.network.internal.EntitySpawnHandler.lambda$channelRead0$0(EntitySpawnHandler.java:55) ~[EntitySpawnHandler.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) ~[?:1.8.0_152] at java.util.concurrent.FutureTask.run(FutureTask.java:266) ~[?:1.8.0_152] at net.minecraft.util.Util.runTask(SourceFile:46) ~[Util.class:?] ... 15 more Doesn't change anything.

I really need this to bring the first real feature to my mod so please? can anyone try to help me.

That's what I've found in the console (should have specified that)

@Animefan8888 Results Valid JSON

No. The only thing about Json I've found: @fcelon still doesn't drop anything new code: { "pools": [ { "name":"cruelars_triforcemod:bokoblin_loot", "rolls": 4, "entries": [ { "type":"item", "name": "cruelars_triforcemod:bokoblin_heart", "weight": 1, "functions": [ { "function": "set_count", "count": { "min": 0, "max": 1 } } ] }, { "type": "item", "name": "cruelars_triforcemod:bokoblin_fang", "weight": 2 },{ "type": "item", "name": "cruelars_triforcemod:bokoblin_horn", "weight": 1, "functions": [ { "function": "set_count", "count": { "min": 0, "max": 1 } } ] },{ "type": "item", "name": "cruears_triforcemod:green_ruby", "weight": 3 } ] } ] }

I'm planning to make similar blocks for the different dungeon environments I'm designing. But I'm in early development so that's all stuff of the future.

I haven't thought of that but this shouldn't be a Problem for me as I'm planning to use these Blocks as obstacles in dungeons not as Material for building invisible things.

Thanks and to all: it would be very helpful if you could find solutions for my other topics

@Legenes, @diesieben07 If it's ok to you, I'll mention you in my changelog false block is an air block that gets invisible when the lens of truth is hold

@LegenesYour code actually solved the Problem! Thanks to everyone.

[19:42:43] [main/WARN]: Unable to resolve texture due to upward reference: #all in minecraft:models/block/cube_all

oh sorry. I had the entityPlayer == null Problem since I started the topic and even before. thought it was because there are problems with world should have changed that by now

So I should use this? @Override public void update() { if (!this.getWorld().isRemote) { EntityPlayer entityPlayer = (EntityPlayer) this.getWorld().getClosestPlayer(this.pos.getX(), this.pos.getY(), this.pos.getZ(), -1.0, false); if (entityPlayer != null) { boolean visible = isVisible(); boolean shouldBeVisible = entityPlayer.getHeldItem(EnumHand.MAIN_HAND).getItem() == ModItems.lens_of_truth || entityPlayer.getHeldItem(EnumHand.OFF_HAND).getItem() == ModItems.lens_of_truth; if (visible != shouldBeVisible) { world.setBlockState(pos, world.getBlockState(pos).withProperty(Hidden_Block.VISIBLE, shouldBeVisible)); } } System.out.println(entityPlayer); } }
