Solved Setting potion effects from config list

Is there any way, to set PotionEffect from list to an player at same time? I know how to set exact one, but how to set list of them?

Code example please!

Thanks in advance!

Code:java

for (String s: getConfig().getStringList("effects")) {
    PotionEffectType effect = null;
 
    try {
        effect = PotionEffectType.getByName(s);
    } catch (Exception ex) {
        ex.printStackTrace();
        break;
    }
 
    player.addPotionEffect(new PotionEffect(effect, duration, amplifier));
}

And your config would look something like this (example):

Code:

effects:
- INVISIBILITY
- JUMP
- ETC

You can modify the code to add the duration and amplifier in the config if you want.

 

If you have a string list, you could use a for-loop for that.

Code:java

for(String effectString : config.getStringList("your.string.list") {
    PotionEffectType type = PotionEffectType.getByName(effectString.toUpperCase());
 
    //if type is null that means that the type could not be interpreted
    if(type == null) {
        System.err.println(effectString + " could not be interpreted into a correct PotionEffectType.");
        continue;
    }
 
    //if the player already has the potion effect, make sure to remove it at first
    if(player.hasPotionEffect(type))
        player.removePotionEffect(type);
 
    //create the effect
    PotionEffect effect = type.createEffect(20 * 30 /* duration in ticks */, 1 /* strength */);
 
    //apply effect to the player
    player.addPotionEffect(effect);
}

This version is not entierly bullet proof: if you want to include duration and strength as a variable that can be changed in the config file, you'll have to find a system to maybe split it using a "," or something.

Also, if the player for instance started out with speed III and you want to add the speed effect of the same type, only with a lower strength, it would remove that effect no matter what. You'd have to check in the second if-statement then, if the strength of the potion effect type is stronger than 1 or something, if you want to include that.

 

felixfritz I'm doing it on similiar way, but will this:

player.addPotionEffect(effect)
add whole list of effects?

Because I already have other part of code, which works with one effect name, is it same with list of effects? I just add list?

 

If you have the list, you can add the effects one by one in a for-loop, just as I showed you.

 

felixfritz It works perfectly, thanks man. Btw. do you have any idea on how to get duration and amplifier for every effect? :/

 

You could maybe design your configuration file somewhat like this:

Code:

effects:
  - JUMP,30,2

So the first number is the amount of time and the second one is the strength. Then you could split the string and interpret everything. This is, what you could put in your for-loop.

Code:java

//make sure there are no whitespaces in the "effectString"
String[] values = effectString.replaceAll(" ").split(",");
 
//create PotionEffectType
PotionEffectType type;
//set default duration to 30 seconds
int duration = 30;
//set default strength to 1
int strength = 1;
 
//get type
type = PotionEffectType.getByName(values[0].toUpperCase());
 
//check, if type is null
 
//set duration
if(values.length > 1)
    duration = Integer.parseInt(values[1]);
 
//set strength
if(values.length > 2)
    strength = Integer.parseInt(values[2]);
 
//check, if player already has potiontype
 
//create the effect
PotionEffect effect = type.createEffect(duration * 20, strength);
player.addPotionEffect(effect);

 

felixfritz I've done it in similiar way, anyway, thanks!
