Solved How do i create game tick loops?

Explain what you want to do. Why do you need ticks? How are you going to take the ticks ?

 

Bukkit.getScheduler().runTaskTimer(plugin, task, delay, period)

This return a BukkitTask that can be cancelled anytime with cancel()

 

Bukkit.getScheduler().cancelTask(taskId)

 

Code (Java):

BukkitTask task = new BukkitRunnable() {
    @Override
    public void run() {
        // do your task
    }
}.runTaskTimer(plugin, 0, 1L);

Runs a specified code every tick. You can simply cancel via

Code (Java):

task.cancel();

 

Does nobody link javadocs anymore? Let OP figure at least a little for themselves.
#cancel only can be called from the BukkitTask returned when you schedule a task (or you can cancel a task by ID, which increments by 1 for each task previously scheduled), or when you use a BukkitRunnable instead of a Runnable, as Runnables do not have a #cancel method.
Take a look at the BukkitScheduler javadocs and the scheduler wiki page.

 

See the answer above, you get the taskId from the runTaskTimer function, so :
int taskId = Bukkit.getScheduler().runTaskTimer(plugin, task, delay, period)
Bukkit.getScheduler().cancelTask(taskId)

Or just look at the BukkitRunable answer from Schottky

 

you can call #cancel from within the task for reference.
