Waiting for Four Seconds


Adityagupta

Recommended Posts

You almost always have an instance of World available, and World#getCurrentWorldTime is given in ticks. Given that there are 20 ticks/second, to wait 4 seconds you want to wait 80 ticks.

I'll help if I can. Apologies if I do something obviously stupid. :D

Here is an example of subclassing and overriding TNT blast sizes:

 

 

 

public class EntityBigTNTPrimed extends EntityTNTPrimed 
{
public EntityBigTNTPrimed(World w, double x, double y, double z, EntityLivingBase placer)
{
	super(w, x, y, z, placer);
	// alter 'fuse' here if different delay is wanted
}

@Override
public void onUpdate()
{
	this.prevPosX = this.posX;
	this.prevPosY = this.posY;
	this.prevPosZ = this.posZ;
	this.motionY -= 0.03999999910593033D;
	this.moveEntity(this.motionX, this.motionY, this.motionZ);
	this.motionX *= 0.9800000190734863D;
	this.motionY *= 0.9800000190734863D;
	this.motionZ *= 0.9800000190734863D;

	if (this.onGround)
	{
		this.motionX *= 0.699999988079071D;
		this.motionZ *= 0.699999988079071D;
		this.motionY *= -0.5D;
	}

	if (this.fuse-- <= 0)
	{
		this.setDead();

		if (!this.worldObj.isRemote)
		{
			this.majorlyExplode(size);
		}
	}
	else
	{
		this.worldObj.spawnParticle("smoke", this.posX, this.posY + 0.5D, this.posZ, 0.0D, 0.0D, 0.0D);
	}
}
private void majorlyExplode()
{
	float f = YOUR_BLAST_RADIUS; // this is a float normally 4.0f
	this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, f, true);
}
}

While loops are a huge no-no in minecraft code. Ticks don't pass during the loop so they easily become infinite.

 

And when you say huge stack trace I'm just going to guess you got a StackOverflow from some loop or another.

 

You need to show us the code you used.

You cache the time, and then compare it for the next twenty ticks.

 

 

long cachedTime = 0L;
boolean shouldRun = true;

@SubscribeEvent
public void someMethod(TickEvent.WorldTickEvent event)
{
    if(event.side == Side.SERVER && event.phase == TickEvent.Phase.START)
    {
        if(shouldRun && event.world.getTotalWorldTime() >= cachedTime + 80)
        {
            cachedTime = event.world.getTotalWorldTime();
            //DO WHATEVER
            if(someConditionThatMeansYouWantToStop)
            {
                shouldRun = false;
            }
        }
        if(someConditionThatMeansYouWantToStart)
        {
            shouldRun = true;
        }
    }
}

 

Another way to do this, if you want to run something every 4 seconds, instead of just waiting 4 seconds from a given time is using the modulo operator

 

if(world.getTotalWorldTime() % 80 == 0) //runs every 80 ticks (given that the method gets called).

What do you mean it doesn't do anything? I use code like that all the time and it works fine.

 

And don't delete code that doesn't work, post it here so that we can help you!

 

We're not just going to give you copy-paste code, that's not how you learn.

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
