Having the above in a while loop*

 

*Defeats the whole purpose.

 

DO NOT USE A LOOP ANYWHERE IN YOUR CODE.  The tick event handler IS the loop.

 

Ok..

 

So basically what I had was WHILE harvest was enabled (enabled by the key press), do some stuff including press down a key, after the key is pressed down I need to count ticks and when x ticks have gone by, release the key.

 

How would I go about doing this if I cant use a while loop?

if(harvest_enabled) { do_stuff(); }

not

while(harvest_enabled) { do_stuff(); }

 

Yes, I realized that you want to "do stuff while harvest is enabled" but "while" has a different meaning in code.  It means "do this thing over and over again until the condition is false, even if that means hogging the CPU and doing nothing else until the universe experiences heat death."

 

What you need to do is press the key and stop doing anything else the rest of this tick.  Then you count ticks.  Then when the counter is big enough, release the key.

 

The tick event handler IS the while loop.

 

If it helps, write out what you want to do as a Finite State Machine.

Guess how Minecraft ticks? It's already in a loop, when the server gets launched, it gets into a snippet

while (this.serverRunning) { // this is the server
      // This is where Minecraft server code happens, including running tick handlers' code every relevant tick depending on what they subscribed for, then it sleeps for at most 50 milliseconds before the loop goes on
}

 

This means that wherever you are in Minecraft, you are on a loop (one of 2 actually, one for server and one for client, but that's not the point). If a lot happens on the same tick, the game lags because the game loop doesn't go on.

Forge added tick handling events so mods can run their code on each relevant tick, if modders want to tick without pausing the game they start counting their ticks (on a global variable you still didn't make) and each time the tick counter reaches certain amount the mod runs its code.

Eeehh, close enough.

You also don't have pressTime ++ anywhere.

SOLVED: Thanks to everyone who helped, especially Draco18s!

 

For anyone who has the same issue in the future:

 

To simulate a delay between two lines of code you cannot use Thread.Sleep() or anything as such because it causes the entire thread, including minecraft to freeze. Instead you must force a line of code to be executed on one tick and wait for another tick to come before executing the next.

 

Example:

 

int pressTime;

public void onPlayerTick(ClientTickEvent event){

    if(pressTime == 20){  *20 TICKS IS 1 SECOND*

        //do one line of code

    }else if(pressTime == 40){  *SIMULATES A 1 SECOND DELAY*

        //do another line of code

    }

    pressTime++;  *increments presstime by 1 every tick.

}

And remember to both initialize and reset pressTime to zero somewhere so you can do your magic first time and every time  :)

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
