How to cancel events from separate events?

Hey. So I've been looking around for a while and can't figure out how to cancel a specific event within another event. For example, I have an event where it checks if the player hasn't moved in 5 minutes. If they haven't, I want to cancel a different event I have (PlayerDeathEvent).
I've tried things like onPlayerDeath.setCancelled, but they don't work.

 

ariaDEE Full code please

 

Code:java

 @EventHandler
public void onPlayerMove(PlayerMoveEvent event){
long lastMoved = System.currentTimeMillis();
lastMoved = System.currentTimeMillis();
if (System.currentTimeMillis() - lastMoved >= 300){
//cancel other event
}
}

Code:java

 @EventHandler
public void onPlayerDeath(PlayerDeathEvent event) {
//event stuff
}

 

You'll want to store the lastMoved per player, like in a hashmap. And then in the PlayerDeathEvent, check the value.

 

Why would I need to store it in a hashmap? And what do you mean by check the value?

 

ariaDEE Because you can't cancel an event from a different event. And by check the value I mean... check the value?

Code:

if(System.currentTimeMillis()- lastMoved >=300){
