Solved ClassCastException when using timers separate class

I'm trying to rewrite my code to follow 'proper' Java coding practice, and when transferring the code through classes (no errors in eclipse), I used the command to start flying, which starts a scheduler, and received a ClassCastException. The error and code snippets are below. (luckily, I know exactly where it is XD)

Error:

Code:

Sorry there's a ton of info, but this is my first time working with many classes, and first time using events and timers in a class other then Main (I know, i'm a noob XD )

Thanks for the help and replies!

Pasted wrong 'Main class' snippet, fixed now.

It doesn't like when you cast Player to the runnable

Code:java

 
.scheduleSyncDelayedTask((Plugin) this, new Runnable() {
 

What you're actually doing here is since you're getting a new Runnable() it's using this as the runnable class
So you'd need to change it to this

Code:java

 
.scheduleSyncDelayedTask(new Main(), new Runnable() {
 

 

Code:

schedulerID.put(p, Main.getInstance().getServer().getScheduler()
.scheduleSyncDelayedTask((Plugin) this, new Runnable() {

In line 35/36 you are casting your Scheduler class to a plugin, replace "this" by an instance of you main class, the one that extends JavaPlugin.

 

Like what I said ^^

 

MrSparkzz Well, your message wasn't there when i posted mine

That's obviously because I'm a ninja

 

Changing 'this' to main instance worked, thanks!
