With this code in eclipse from one of my private mods:

@SubscribeEvent
    public void AccessEnchant(LivingHurtEvent fEvent, World world)
    {
        if(fEvent.source.damageType != "player" && fEvent.source.damageType != "mob")
            return;
        
       
        
        if(!(fEvent.source.getSourceOfDamage() instanceof EntityLivingBase))
            return;
        
        EntityLivingBase attacker = (EntityLivingBase)fEvent.source.getSourceOfDamage();
        if(attacker == null)
            return;
        
        ItemStack dmgSource = ((EntityLivingBase)fEvent.source.getSourceOfDamage()).getHeldItem();
        if(dmgSource == null)
            return;
        
        if(EnchantmentHelper.getEnchantmentLevel(effectId, dmgSource) <= 0)
            return;
        int levelSunshine = EnchantmentHelper.getEnchantmentLevel(effectId, dmgSource);
        
        
         
        final World w = world;
                long wt = w.provider.getWorldTime();
                long constantTime = w.provider.getWorldTime ();
             
                int timeDay = 0;
                int timeNight = 11999;
                int wt2 = (int) wt;
                
                while(wt2 < 24001){
                    wt2 = wt2 - 24000;
                    
                }
                if((timeNight) > wt2)  {
                 fEvent.ammount = fEvent.ammount * (0.9f + (0.30f * levelSunshine));
                  return;
                }
                  else if(timeDay < wt2)
                  {
                      
                 fEvent.ammount = fEvent.ammount - (0.75f * levelSunshine);
                  }  
                      
                }

    }

1.7.10 is no longer supported on this forum, your thread will probably be closed by a mod.

 

That said, the error tells you the problem:

Quote

Method public void [...] has @SubscribeEvent annotation, but requires 2 arguments.  Event handler methods must require a single argument.

You have two arguments in your event handler method, which is an invalid use of @SubscribeEvent. Event handler methods must have just one argument, the Event type.

Ok thanks

Uhm Last Question how do I get to put 2 or more arguements that work properly without any errors. Regardless of the method how can it be done?

If you want it to be an event handler method, you can't have multiple arguments. If you need a World object for your code, get it via the event itself.
