Hello,

I am trying to make a structural block that is non spawnable.

I looked up the GLASS block and found that it set isValidSpawn.

But I cannot figure out how to set it correctly, 

public static final BlockBehaviour.Properties TEST_BLOCK_PROPERTIES = BlockBehaviour.Properties
            .of(Material.HEAVY_METAL, MaterialColor.TERRACOTTA_BLACK)
            .strength(-1.0F, 3600000.0F)
            .noDrops()
            .sound(SoundType.METAL)
            .isValidSpawn(Blocks::never);

IntelliJ reports the following problem:

Quote

'never(net.minecraft.world.level.block.state.BlockState, net.minecraft.world.level.BlockGetter, net.minecraft.core.BlockPos, net.minecraft.world.entity.EntityType<?>)' has private access in 'net.minecraft.world.level.block.Blocks'

If I change the Blocks::never to false then I get the following error instead

Quote

'isValidSpawn(net.minecraft.world.level.block.state.BlockBehaviour.StateArgumentPredicate<net.minecraft.world.entity.EntityType<?>>)' in 'net.minecraft.world.level.block.state.BlockBehaviour.Properties' cannot be applied to '(boolean)'

 

never is a private method.

{

private static Boolean never(BlockState p_50779_, BlockGetter p_50780_, BlockPos p_50781_, EntityType<?> p_50782_) { return (boolean)false; }

}

I am sure you could figure out your own method.. but I'd choose to copy the blockbehavior of a nonspawnable block, and override the attributes to get what I wanted.

You could copy the blockbehavior of 'glass' and override the other properties, and thiss will pull the spawning blocking.
