PlayerEntity properties only valid on client side?

[TheJays]

Hi,

 

I'm working in: forge:1.15.2-31.2.0

 

I have a item that overrides the following method

public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected)

 

inside this method i check various properties of the player, however it seems that when inside the scope of that property its only being ran on the client. 

the example below will add SlowFalling to the player if they are airborne & damage the itemstack. 

 

@Override
    public void inventoryTick(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
        if (!getActive(stack))
            return;

        PlayerEntity player = (PlayerEntity)entityIn;

        if (player == null)
            return;

        if (player.isAirBorne){
          // THIS IS CLIENT SIDE ONLY
            player.addPotionEffect(new EffectInstance(Effects.SLOW_FALLING, 1, 1));
            UtilItemStack.damageItem(stack);
        }
        
    }

 

This causes an issue. in this example, the player is given the slowfalling effect. but will take fall damage upon landing.

 

This is not the case if i apply the effect if i apply the effect outside of that scope. 

 

I remember this working before the method was changed from `tick` to `inventoryTick`

 

Does anyone have any advice? 

 

Thank you in advanced.

What is getActive()?

And the casting and null checking is pointless and won’t work.

[TheJays]

getActive() is a method to check some NBT data. 

 

The cast and null check is a habit. but doesn't affect anything.
