How to get/check player hp

Recommended Posts

Hey, i havent made mods in minecraft before and im currently starting out with trying to make some small simple mods.

 

Im currently trying to make a mod that checks when youre below a certain hp value and then gives you slowness or another potion effect.

I tried searching on google how to get the value from the player health as a int/var to use in a if sentence.

 

If anyone knows how to do this please respond! :)

FMLClientSetupEvent is only called once, and is only called on the client (you'll want to give potion effects on the server), so the event you should use is TickEvent.PlayerTickEvent, then event.player.getHealth() to get the health, and lastly to add a potion effect you can also call .addEffect on the player instance provided by the event

Alright. the FMLClientSetupEvent is not the corret event to listen to (at all).

You will need to listen for the PlayerTickEvent event.

public class PlayerTickHandler {

    @SubscribeEvent
    public void onPlayerTick(TickEvent.PlayerTickEvent event) {
        PlayerEntity player = event.player;
        if (player.getHealth() < 7) {
            player.addPotionEffect(new EffectInstance(Effects.SLOWNESS, 60));
        }
    }
}

And register it for Forge event bus inside your mod's construcor like this: 

MinecraftForge.EVENT_BUS.register(new PlayerTickHandler());

Note the @SubscribeEvent, this essentially tells forge that the methods is listening for an event.

that's a bad idea, add the Effect for example when the Player joins the World or when he mine a Block but not each Tick

use the @EventBusSubscriber annotation you need to pass as parameter the Mod Id

what did you try to achieve?

This gave me this error

    • Yeah that's the correct Forum Experience (a lot since he join 2012) and knowledge from other threads with similar problems
    • I had tried using ContainerData before but I didn't notice addDataSlots in AbstractFurnaceMenu. After adding it to the constructor it worked. Thank you.
    • I'm assuming its in the wrong class because of this line ? Which would make it Client side ? @Mod.EventBusSubscriber(modid = MyMod.MODID, bus = Bus.MOD, value = Dist.CLIENT) Would removing this and setting up the MyMod.java like this be correct? I ask because I see other examples use the public static final RegistryObject<> in the same class that they setup the public static final DeferredRegister<>, and not for just particles. public MyMod() { // Register the setup method for modloading IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus(); ParticleRegistration.PARTICLES_TYPES.register(bus); } Or do I need to make further changes to the registration then? Such as moving the registerParticleFactory() to a ClientStartup/ClientProxy ?
