[1.15.2] Remove Slowness when using an Item


xanderindalzone
 Share

Recommended Posts

I finally figured out how to make my Gun semi auto by overriding the getUseDuration() from the Item Class, but for some reason it adds a slowness effect when holding right click(continously using the item).

How could I remove this slowness when using/holding right click with the Gun Item?

LivingEntity#removePotionEffect(Effect)

Edit: Oof, thought you meant a potion effect, I should really take my time and read these in detail.

Edited by Novârch

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".

I've already tried that, the automatic slowness overrides it

Are you sure? This code works for me (and makes the player really fast when using items):

@SubscribeEvent
  public static void onItemUse(LivingEntityUseItemEvent event) {
  if (event.getEntityLiving() instanceof PlayerEntity) {
    PlayerEntity player = (PlayerEntity)event.getEntityLiving();
    player.getAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(2);

  }
}

ok lol, i was editing the player's abbilities instead of the attributes XD.

 

thx. i'll try that in a bit.

Bugs how exactly? Is the speed unchanged, or is it the FOV that is changing as in the previous video you shared?

it changes speed and FOV, and while using the item it doenst appear to be affecting the speed, but I cant really tell because the FOV effect alters the perspective

I know it is kind of a band aid on top of a band aid, but if you try to stop the FOV update with FOVUpdateEvent you could more easily observe any speed changes.
