#

because currently thats the only thing that could be causing this issue

#

ok lets do some trial and error using stupid stuff quickly

#

when the cooldown is added

#

remove the players ability to fly

#

when the cooldown is removed, give the ability back

like this?

dire vector Mar 8, 2022, 11:24 AM

#

yeah

#

see if that works

#

doing it like that since I know mineplex and hypixel do that too

royal linden Mar 8, 2022, 11:25 AM

#

now it works perfectly fine

dire vector Mar 8, 2022, 11:25 AM

#

oh

#

so it couldve been an issue when the event was being cancelled

royal linden Mar 8, 2022, 11:25 AM

#

but sometimes I get falldamage, could you help me cancelling that?

dire vector Mar 8, 2022, 11:25 AM

#

but now they cant fly at all when cooldown is added, so no chance of doing it again

royal linden Mar 8, 2022, 11:25 AM

#

oh

dire vector Mar 8, 2022, 11:25 AM

#

including non-double jump fall damage or all fall damage?

royal linden Mar 8, 2022, 11:26 AM

#

non-double jump fall damage

#

oh no wait, I need no fall damage at all, but I can do this at my own ig

#

but can I use the double jump code now or is this smth like the wrong way?

dire vector Mar 8, 2022, 11:27 AM

#

make a Set or something of when a player double jumps, and next time they take damage (EntityDamageEvent), check if its for DamageCause.FALL, and if it is, cancel it and remove them from the set

#

no its fine if it works

#

remove that commented line tho

#

otherwise if you want to yeet all fall damage, just listen to the EntityDamageEvent and if its damage cause FALL, then cancel it

royal linden Mar 8, 2022, 11:28 AM

#

Oh, and one more question:
Im not sure if I am wrong or not but I think I get the Y-Boost in Gamemode 1 too when flying up, how can I fix that?

dire vector Mar 8, 2022, 11:28 AM

#

that code wont be doing it

#

there is a very slight Y boost in normal minecraft when you do fly so it could be that

royal linden Mar 8, 2022, 11:29 AM

#

ohh

#

okay

#

thank you soooo much :)

dire vector Mar 8, 2022, 11:29 AM

#

took longer to solve than it shouldve lol

#

note to self: dont trust Event#setCancelled

royal linden Mar 8, 2022, 11:30 AM

#

lol

#

Ive tried to do that like 6 months ago

#

but back then I couldnt do that

dire vector Mar 8, 2022, 11:31 AM

#

to a simple problem, there'll always be a stupid explanation

royal linden Mar 8, 2022, 11:31 AM

#

yeah, thank you :)

royal linden Mar 8, 2022, 11:34 AM

#

dire vector otherwise if you want to yeet all fall damage, just listen to the EntityDamageEv...

    @EventHandler
    public void onEntityDamage(EntityDamageEvent e) {
        if (e.getCause().equals(EntityDamageEvent.DamageCause.FALL)) {
            e.setCancelled(true);
        }
    }```
should work like this, right?

dire vector Mar 8, 2022, 11:34 AM

#

yes

#

thatll work
