[1.17] Custom fishing rod error


Recommended Posts


I am trying to use this, but when I create the CustomFishingHook, the call to super.tick goes wrong and does not work properly.

I would like to know how to run the supertick (Projectile.tick) and what the solution is.

I tried to create it, but CustomFishingHook shouldStopFishing is not referenced.



protected net.minecraft.world.entity.projectile.FishingHook
protected net.minecraft.world.entity.projectile.FishingHook$shouldStopFishing


public class CustomFishingHookaa extends FishingHook{

    public CustomFishingHookaa(EntityType<? extends CustomFishingHookaa> p_150138_, Level p_150139_, int p_150143_, int p_150144_) {
        super(p_150138_, p_150139_);
        this.noCulling = true;


    public CustomFishingHookaa(Player p_37106_, Level p_37107_, int p_37108_, int p_37109_) {
        this(ModEntities.MODFISHING_BOBBER, p_37107_, p_37108_, p_37109_);
        float f = p_37106_.getXRot();
        float f1 = p_37106_.getYRot();
        float f2 = Mth.cos(-f1 * ((float)Math.PI / 180F) - (float)Math.PI);
        float f3 = Mth.sin(-f1 * ((float)Math.PI / 180F) - (float)Math.PI);
        float f4 = -Mth.cos(-f * ((float)Math.PI / 180F));
        float f5 = Mth.sin(-f * ((float)Math.PI / 180F));
        double d0 = p_37106_.getX() - (double)f3 * 0.3D;
        double d1 = p_37106_.getEyeY();
        double d2 = p_37106_.getZ() - (double)f2 * 0.3D;
        this.moveTo(d0, d1, d2, f1, f);
        Vec3 vec3 = new Vec3((double)(-f3), (double)Mth.clamp(-(f5 / f4), -5.0F, 5.0F), (double)(-f2));
        double d3 = vec3.length();
        vec3 = vec3.multiply(0.6D / d3 + 0.5D + this.random.nextGaussian() * 0.0045D, 0.6D / d3 + 0.5D + this.random.nextGaussian() * 0.0045D, 0.6D / d3 + 0.5D + this.random.nextGaussian() * 0.0045D);
        this.setYRot((float)(Mth.atan2(vec3.x, vec3.z) * (double)(180F / (float)Math.PI)));
        this.setXRot((float)(Mth.atan2(vec3.y, vec3.horizontalDistance()) * (double)(180F / (float)Math.PI)));
        this.yRotO = this.getYRot();
        this.xRotO = this.getXRot();

    public CustomFishingHookaa(EntityType<CustomFishingHookaa> customFishingHookEntityType, Level level) {
        this(customFishingHookEntityType,level, 0, 0);

    protected  boolean shouldStopFishing(Player p_37137_)  {
        ItemStack itemstack = p_37137_.getMainHandItem();
        ItemStack itemstack1 = p_37137_.getOffhandItem();
        boolean flag = itemstack.getItem() instanceof Netherite_Rod;
        boolean flag1 = itemstack1.getItem() instanceof Netherite_Rod;
        if (!p_37137_.isRemoved() && p_37137_.isAlive() && (flag || flag1) && !(this.distanceToSqr(p_37137_) > 1024.0D)) {
            return false;
        } else {
            return true;


I've seen the documentation, but I'm not sure if it's correct.

This is incorrect on multiple levels:

  • Why did you try to make the class protected?
  • That is the wrong syntax for ATing a field.

Since shouldStopFishing is private, I thought I could make it protected and reference it.


# Makes protected the 'COLOR_WHITE' field in Gui
protected net.minecraft.client.gui.Gui f_168667_ # COLOR_WHITE

If it is a field, should I use this example?

But we don't know why.
This may be my lack of knowledge about java.


I'll check again.

I was able to implement it by re-reading each one.

I'm getting an Override error message, should I continue developing?

It has taken me a long time to get to this point. Can I post the whole code in case someone else has a similar problem? (Fill in or Github link)

I'm very grateful.  Thank you.

How on earth did you upload this Git Repo, use a Git Client!
In addition, you should use the .gitignore from the mdk when uploading. It ensures that the correct files/folders are upload,
also stop putting your project in a separate folder.

Did you refresh the gradle dependencies?
