Effect in one world

[Matias Lund]

Hey, so i'm very new to skript and i would like help with a problem. So i want to give an effect in one world. So when the player joins the world he automatically gets an effect.

This is my script for now:

if player is in world "Void":
apply potion of speed of tier 1 to player for 30 minutes
else if player isn't in world "Void" don't apply

^^ The problem is that i still have the effect in other worlds. So how do i cancel the effect when i return to another world? And how do a apply to the player when he joins the world?

Thanks :3

you can check on enter of the world, if its not the void world, remove potion effect of speed
note you don't need the 3rd line it just won't do anything if not in that world

Sorry ...

if player is in world "world":
    apply speed 2 to player

Sorry im not exactly sure what the syntax for applying a potion effect is but you could probably guess what I mean
