I need to check the block on the server side but can't find isClientSide

more precisely, I need a condition for the method that works on the new version

depending on the context and location of the call, the method of obtaining it may differ significantly, but it is always Level

example: the Player parameter is passed to a certain method

public boolen anyMethod(ServerPlayer player, par1, par2) {...}

you will receive the client side as follows

player.getLevel.isClientSide

server code is written in a block if (! player.getLevel.isClientSide){///}

client code is written in a block if (player.getLevel.isClientSide){///}

 

in some cases, the world can be passed directly to the method, but I don’t remember this in my practice

in almost all cases I get the client side from LivingEntity.getLevel.isClientSide

 

example 2: the client side is taken from the event

public static void onPlayerJoin(EntityJoinLevelEvent event){
            if(!event.getLevel().isClientSide()){
                if(event.getEntity() instanceof ServerPlayer player){
                    val = event;
                    RegisterPlayer registerPlayer = new RegisterPlayer();
                    registerPlayer.start();
                    SetupQuestCoreForPlayer setupQuestCoreForPlayer = new SetupQuestCoreForPlayer();
                    setupQuestCoreForPlayer.start();
                }
            }

here you can also get the client side via event.getEntity().getLevel().isClientSide() OR event.getLevel().isClientSide()

sorry my ENGLISH is very bad
