[1.15.2] Float capability not exact


ScottBot10

Recommended Posts

I have a float Capabilty for players and I have it so that it increases by 0.05 when a certain item is used.

But when I use the item it does not increase exactly. (For example, instead of going from 1.05 to 1.1, it goes to 1.0999999).

How would I fix this?

 

Relevant code:

// SkillLevel.java
public class SkillLevel implements ISkillLevel {

    private float level = 1F;

    @Override
    public void remove(float num) {
        this.level -= num;
    }

    @Override
    public void add(float num) { this.level += num; }

    @Override
    public void set(float num) {
        this.level = num;
    }

    @Override
    public float getLevel() {
        return this.level;
    }
public static class SkillLevelProvider implements ICapabilitySerializable<FloatNBT> {

    @CapabilityInject(ISkillLevel.class)
    public static Capability<ISkillLevel> SKILL_CAP;

    private LazyOptional<ISkillLevel> instance = LazyOptional.of(SKILL_CAP::getDefaultInstance);

    @Nonnull
    @Override
    public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nullable Direction side) {
        return SKILL_CAP.orEmpty(cap, instance);
    }
    @Override
    public FloatNBT serializeNBT() {
        return (FloatNBT) SKILL_CAP.getStorage().writeNBT(SKILL_CAP, instance.orElseThrow(() -> new IllegalArgumentException("LazyOptional cannot be empty!")), null);
    }

    @Override
    public void deserializeNBT(FloatNBT nbt) {
        SKILL_CAP.getStorage().readNBT(SKILL_CAP, instance.orElseThrow(() -> new IllegalArgumentException("LazyOptional cannot be empty!")), null, nbt);
    }
}
@Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) {
      ISkillLevel skill = playerIn.getCapability(SkillLevel.SkillLevelProvider.SKILL_CAP).orElse(null);
      skill.add(0.05f);
      System.out.println(skill.getLevel());
    }

Thanks!

Make a computer that has infinite accuracy. Your problem lies with the precision of floating point notation.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

    • Me and my friend started a server using Better Minecraft and added about 10 mods on top of it. Everything works fine until we hover over any armor item in the game. Doesnt matter what mod its from it just crashes. We can hover over armor in JEI but it just gives us a tooltip error. Here is my crash message after hovering over armor The game crashed whilst rendering screen Error: java.lang.NullPointerException: Registry Object not present: feathers:lightweight Here is my Crash Report https://pastebin.com/FWQ7n3HS
    • I am unable to resolve my current issue, I have successfully downloaded the forge extension. I downloaded the correct Java link with Javafix included. I log into the game and it shows the "forge" launcher active menu. I double checked to make sure it was the right release number of minecraft and it matched the forge download as well, this also including the most recent forge client. The issue is when I go into a new minecraft server it doesn't allow me to do //wand. No matter what I try the same issue is following me, it almost seems as if the client is fully active but something isn't allowing it to run on my computer. I would appreciate some assistance regarding my problem.   Thank you
    • Came here for the same reason. But for me it's the client. After following your instructions with the jar, I ended up with the following error.
