Since using the Slowness Potion to implement the zoom function is simpler,

I would appreciate it if you watch this tutorial just for fun. :)
*Of course, adjusting the FOV value directly through code gives better zooming effect

The completed version looks like this.

Step1. I will create keybindings.

Step2. Zoom-in procedure.

The trigger below is temporarily added and will be removed later in the code.

Step3. Zoom-out procedure.

Step4. Zoom-in procedure Code.

import net.minecraft.client.Minecraft; //add
import net.minecraft.world.entity.player.Player; //add
import net.minecraft.client.Options; //add

public class ZoomInProcedure {
public static void execute(Entity entity) {
if (entity == null)
return;
if ((entity instanceof LivingEntity _livEnt ? _livEnt.getMainHandItem() : ItemStack.EMPTY).getItem() == TestModItems.SNIPER.get()) {

~~entity.setTicksFrozen(0);~~ //delete code
Player player = Minecraft.getInstance().player; //add
Minecraft.getInstance().options.fov().set(30); //add

The maximum zoom value is 30~110. Values higher than this will not work.

Step5. Zoom-out procedure Code.

import net.minecraft.client.Minecraft; //add
import net.minecraft.world.entity.player.Player; //add
import net.minecraft.client.Options; //add

public class ZoomOutProcedure {
public static void execute() {
Player player = Minecraft.getInstance().player; //add
if (player != null) { //add
Minecraft.getInstance().options.fov().set(70); //add

It’s complete.

Due to a bug where the FOV value starts at 30 upon rejoining, you can fix this issue by using the corresponding trigger block when creating the ZoomIn procedure.
