Confirmed. Eye of Ender cannot be thrown.
Ill try and see if this works and tell the mods if its a real 1 or not
I thought you can't even use Eye of Enders when "generate-structures" is set to false.
Tan Chin Cheern you can't, but it'll throw this error, that's what the report is about, I don't see the error myself tho.
SuperKawaii, [Mod] md_5 is a "honorary mod" to quote [Mojang] Nathan Adams, hench why his name is green.
Please link to this comment in the description
The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.
The reason for this is that the field net.minecraft.world.gen.MapGenBase.worldObj is null if the Stronghold was not generated. This could be solved by having the method net.minecraft.world.gen.ChunkProviderOverworld.getStrongholdGen(World, String, BlockPos) return null. Either by not initializing the field net.minecraft.world.gen.ChunkProviderOverworld.strongholdGenerator if no structures should be generated or by returning null if no structures should be generated (!(this.mapFeaturesEnabled && this.settings.useStrongholds)).
Cannot reproduce in 1.11.2. Can someone else confirm if this is fixed?
Cannot reproduce in 1.11.2 either. The eye of ender cannot be thrown, but an error is not printed.
