Sorry this is taken from another API but these are some pretty decent sleep methods IMO.

 

sleep.delayUntil(() -> player.getAnimation == -1);

sleep.delayUntil(() -> someInterface.isVisible(), 400, 800);

 

etc, etc.

 

static void delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition)

Delays until condition returns true.

static boolean delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition, java.util.concurrent.Callable<java.lang.Boolean> reset, int timeout) static boolean delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition, java.util.concurrent.Callable<java.lang.Boolean> reset, int minTimeout, int maxTimeout) static boolean delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition, java.util.concurrent.Callable<java.lang.Boolean> reset, int frequency, int minTimeout, int maxTimeout)

Delays execution of the current thread until the condition is met (returns true) The current result will be checked every X milliseconds (frequency) until the condition is met or the timeout is reached

static boolean delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition, int timeout)

Delays execution of the current thread until the condition is met (returns true) The current result will be checked every Math.min(100, timeout / 20) milliseconds (frequency) until the condition is met any the timeout is reached

static boolean delayUntil(java.util.concurrent.Callable<java.lang.Boolean> condition, int minTimeout, int maxTimeout)
