How to get "this" as instance in mixin inject target?

[Hipposgrumm]

I am trying to mixin to the Vex class to give itself an effect if the owning evoker has said effect. The only problem is I can't reference the "this" object from the Vex class and there is no entity getter method or variable to get the vex entity (just the owner).

package gg.hipposgrumm.intangibility.effects.intangibility.special_cases;

// Imports Ommitted

@Mixin(Vex.class)
public class EvokerVexIntangibleLifelink {
    @Shadow
    @Nullable
    private Mob owner;

    @Inject(method = "Lnet/minecraft/world/entity/monster/Vex;tick()V", at = @At("HEAD"))
    private void intangibilitypotion_ifvexsummonerisintangiblebecomeintangible(CallbackInfo ci) {
        if (this.owner.hasEffect(Main.INTANGIBILITY.get())) {
            ((Vex)this).addEffect(new MobEffectInstance(Main.INTANGIBILITY.get(), this.owner.getEffect(Main.INTANGIBILITY.get()).getDuration()));
        }
    }
}

This is the method I am trying to inject into:

   public void tick() {
      this.noPhysics = true;
      super.tick();
      this.noPhysics = false;
      this.setNoGravity(true);
      if (this.hasLimitedLife && --this.limitedLifeTicks <= 0) {
         this.limitedLifeTicks = 20;
         this.hurt(DamageSource.STARVE, 1.0F);
      }
   }

Is there any easy way to do this?

This is a question for the mixin discord; however, you should have read the docs first since it literally goes over scenarios like this.

[Darkorg69]

first your mixin should extend/implement everything the target class is extending or implementing

second, always declare your mixins abstract so you don't accidentally instantiate them.

then just cast ((object) (target class) this).->... it should work as both mixin class and target class are objects
