Animated blocks do not stop their animation in the pause menu

@unknown the issue you're describing is MC-118002, which is linked above in "related to". It's already fixed for the next version and was not caused by the texture animations.

what

Can I ask why is this intended?

This does also affect sculk sensors, shriekers and blocks.

This issue also affects particle "minecraft:vibration", because it uses the same animation method as blocks. Video attached reproducing this issue in latest snapshot (23w44a).

The main reason (I think) Dinnerbone marked this issue as WAI is because the fix applied for MC-116696 directly contradicts the fix this bug needs, inside the code. What it's happening here is that the advancements screen is a menu that also pauses the game, so if this bug got fixed the easiest way (just readding the "if not paused" check to the TextureManager.tick() call on Minecraft.tick()), MC-116696 would reappear because AdvancementsScreen is a "pausing screen".

//class Minecraft.java
   public void tick() {
      if (this.rightClickDelay > 0) {
         --this.rightClickDelay;
      }

      this.profiler.push("gui");
      this.chatListener.tick();
      this.gui.tick(this.pause);
      this.profiler.pop();
      this.gameRenderer.pick(1.0F);
      this.tutorial.onLookAt(this.level, this.hitResult);
      this.profiler.push("gameMode");

      if (!this.pause && this.level != null) {
         this.gameMode.tick();
      }

      this.profiler.popPush("textures");

      if (this.level != null) {//what should be here is " && !this.pause" but can't really do it because of MC-116696
         this.textureManager.tick();
      }
      //...
   }

Yeah, you would say that by simply adding a "is advancements screen", the two bugs would get fixed, but no, instead, textures would get animated when you have the advancements screen open. Making the advancements screen a non-pausing screen wouldn't be a good option either, because that wouldn't make much sense since this is very often opened from the pause menu. Also I forgot to mention that MC-116696 also affected the statistics screen.
