Im making a custom swordItem that gives the player the wither effect when you right click the sword and when you click it again the effect goes away. My problem is when I try and get rid of the effect it visually goes away but im still taking damage and after a few seconds the visual effect comes back. http://prntscr.com/p8poj9

You cannot store data like that in the Item class, there is only one instance of that class. Potions must also only be modified on the server.

How do you modify potions server side?

How would I get a line of code to run on the logical server?

You query the isRemote field of a World object...

if (!world.isRemote) { /*Whatever*/ }

...where world is an instance of World.

 

Fancy 3D Graphing Calculator mod, with many different coordinate systems.

Lightweight 3D/2D position/vector transformations library, also with support for different coordinate systems.

You can't "make it run" on the logical server. Either the method you are using is called on only one side (then you dont need to check) or it's called on both sides, then you can use isRemote to check the current one.

So I checked world.isremote and it = true right now which means its on the logical client. Thats interesting and all but how could I get playerIn.removeActivePotionEffect(Effects.WITHER); to actually remove the effect?

It should be called twice. Post your updated code.

You have to do it on the logical server.

public class WitherSwordItem extends SwordItem{

    private CoolDowns cooldown = new CoolDowns();

    public WitherSwordItem(IItemTier p_i484601, int p_i484602, float p_i484603, Properties p_i484604) {

        String pName = playerIn.getDisplayName().toString();
        ItemStack item = playerIn.getHeldItem(handIn);
        if(!worldIn.isRemote) {
            if (cooldown.isDone("WitherSwordRightClick", pName , 3000)){
                if(!active.contains(pName)){
                    System.out.println("On");
                    active.add(pName);
                    playerIn.addPotionEffect(new EffectInstance(Effects.WITHER, 999999999, 0));
                    playerIn.playSound(SoundEvents.ENTITY_WITHER_AMBIENT, 100, 0);
                }else{
                    System.out.println("Off");
                    active.remove(pName);
                    System.out.println(worldIn.isRemote());
                    playerIn.removeActivePotionEffect(Effects.WITHER);
                    playerIn.playSound(SoundEvents.BLOCK_LAVA_EXTINGUISH, 100, 0);
                    
               
                }
            item.damageItem(1, playerIn, null);
            }

        }
        return new ActionResult<ItemStack>(ActionResultType.SUCCESS, item);
    }
    
}

I know if(!worldIn.isRemote) makes it false but the code doesn't run, I'm sorry i'm not getting how to do this

Which part of the code? All of it(the method never gets called)? Past a certain if statement?

  Well all the code runs but the playsound, addpotioneffect, removepotioneffect does nothing when I have if(!worldIn.isremote)

How did you confirm this? Those methods should all work save for the EntityPlayer#playSound which doesnt work on the logical server you need to use another method. See here for more info.

I managed to get everything to work except getting rid of the wither effect on the client side, I made a if(worldIn.isremote) statement to add the sounds which works fine. How would I get rid of the visual effect client side?

No don't do that. That's not what you should do at all use one of the other methods of playing a sound.

It should go away when you remove it on the server.

The damage dealing goes away but the visual effect stays, isn't checking if world.isremote is false doing it server side?

Okay I'll get on that but why does the wither effect visual stay? I remove it the damage goes away but the visual effect stays

No. Capabilities exist.

Also good job linking someone using 1.14.4 to the 1.9.4 documentation.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
