Posted October 8, 20195 yr I want to update a block (change it's state) after a certain period of time, if an action has been done. This is what I did just as a test, I know it's wrong. Spoiler package mymod; import java.util.Random; import net.minecraft.block.Block; import net.minecraft.block.BlockState; import net.minecraft.block.Blocks; import net.minecraft.util.math.BlockPos; import net.minecraft.world.World; public class Copper extends Block { private int i; public Copper(Properties properties) { super(properties); } @Override public void animateTick(BlockState stateIn, World worldIn, BlockPos pos, Random rand) { i++; if (i > 5) { worldIn.setBlockState(pos, Blocks.LAVA.getDefaultState()); } } } This'll work for the first block and get it to turn into lava after 5 or however many ticks. I'm not sure what method to actually use, as the other tick ones are deprecated and don't work. I also need to be able to grab a capability in the method so that I can use that and not an instance variable that wont work when there are multiple instances. Or.....is there a better way altogether? Edited October 21, 20195 yr by MineModder2000

October 9, 20195 yr Author How exactly do I get boolean properties to work in blocks? I tried this : Spoiler public class Copper extends Block { public static final BooleanProperty LIT = BlockStateProperties.LIT; public Copper(Properties properties) { super(properties); } public boolean onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) { worldIn.setBlockState(pos, state.with(LIT, Boolean.valueOf(true)), 1); } @OnlyIn(Dist.CLIENT) public void animateTick(BlockState stateIn, World worldIn, BlockPos pos, Random rand) { if (stateIn.get(LIT)) { // do stuff } } } But got this : Cannot set property BooleanProperty{name=lit, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{mymod:copper} Edited October 9, 20195 yr by MineModder2000

The tick method is definitely called, as my block gets a fire on top of it when activated (after 60 ticks).

Make your block infinitely burnable (like netherack) and set the fire once in onBlockActivated. Then you don't need the tick method or the LIT property at all.

The cast is necessary in order for that particular method to be accessible. I tried the hand parameter to begin with, but I couldn't see any way to get the held item from it. Yes, this code is temporary, and I am contemplating even having the block constantly on fire. The reason for the lit property is that I didn't want the block to start throwing particles until it was on fire.

Anyways back to the boolean property, I figured out the issue. The line : worldIn.setBlockState(pos, state.with(LIT, true), 3); in the tick method doesn't set the value to true, as confirmed by println. So whatever value it's set to in the onBlockAdded method, is what it stays as. Hence the reason the if statement check in the animateTick method fails....
