[1.15.2]

 

I am going to have a tough time describing this, so here is a video.

If you saw the video, you saw the after the car go damaged and then healed by my custom item, the car takes way more damage then it should when it hits the cactus. 

I am sure that it is because I am not updating the entity health on server side, so how am I supposed to update the entity's health (on server side)?

 

and here is my code (which heals the car)

 @SubscribeEvent
    public void keyInputEvent(InputEvent.KeyInputEvent event) {
        Minecraft minecraft = Minecraft.getInstance();
        PlayerEntity player = minecraft.player;
        if(player == null)
            return;
        LivingEntity car = (LivingEntity)player.getRidingEntity();
        if (car != null) {
            if (car.getName().getString().equals("Car")) {
                if (event.getKey() == GLFW.GLFW_KEY_R && event.getAction() == GLFW.GLFW_PRESS) {
                    if(player.getHeldItemMainhand().getItem() == RegistryHandler.GAS_CAN.get()){
                        ((Car)car).Refule();
                        car.heal(1);
                        player.getHeldItemMainhand().shrink(1);
                    }
                }
                if(event.getKey() == GLFW.GLFW_KEY_R && event.getAction() == GLFW.GLFW_PRESS){
                    if(player.getHeldItemMainhand().getItem() == RegistryHandler.REPAIR_KIT.get() && car.getHealth() != car.getMaxHealth()){
                        car.heal(6);
                        player.inventory.mainInventory.get(player.inventory.currentItem).shrink(1);
                    }
                }
            }
        }
    }

Send a packet to the server or the better answer would be handle the logic on the server completely. Only thing you need to send is nothing.

So, I have to send an empty packet to server?

Don't compare strings. Use instanceof. You already use a cast later down.

Why are you performing this particular check twice?

Use an early return here like you did with a null player.

((Car)car).Refule();

"Refuel."

 

And finally:
Why are you bothering with R keypresses? Why not use the systems Minecraft already has in place (right clicking with a stack)? Then you don't need this key press handler at all and can put this logic inside your item (where it belongs) and don't need to deal with custom packets.

Wait, how would I put this logic in my item?

Item has methods for onRightClick and onEntityInteract (you'll have to poke around for exact method names). Just override them and put your functionality there.

Works now thanks!

here is code to override for those who are wondering.

 

 @Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) {
        Entity entity = playerIn.getRidingEntity();
        if(entity instanceof Car){
            Car car = (Car)entity;
            car.Refuel();
            car.heal(1);
            playerIn.inventory.mainInventory.get(playerIn.inventory.currentItem).shrink(1);
        }
        return ActionResult.resultPass(playerIn.getHeldItem(handIn));
    }
