Is it possible?

Is it possible to substitute a potion effect type for a variable?


somthing like

Show Spoiler Hide Spoiler

Code:

player.addPotionEffect(new PotionEffect(Variable1, 18000, 2));

Then Variable1 would be in the config and set by a server owner, So if the owner put in the config Jumpboost, then the player would get Jumpboost upon typing that command, or if the owner put Slow then the player would get Slowness when the command is typed

 

Hello xXShadowGuy3Xx,
yes it is:

Code:java

new PotionEffect(PotionEffectType.getByName("POTION NAME HERE"), 0, 0);

but make sure that the EffectType is not null.

 

Thanks for the help, trying it out now!

How can i make sure the effect type is not null?


Here is what i have in my command executer:

Show Spoiler Hide Spoiler

Code:java

package com.gmail.yyamiyyugi;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
 
public class SlashPotionCommandExecuter implements CommandExecutor {
 
    private Main plugin;
 
    public SlashPotionCommandExecuter(Main plugin) {
        this.plugin = plugin;
    }
 
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label,
            String[] args) {
        String C1 = plugin.getConfig().getString("Command1");
 
        String B1 = plugin.getConfig().getString("Bonus1");
 
        String D1 = plugin.getConfig().getString("Downside1");
 
        int B1T = plugin.getConfig().getInt("Bonus1Ticks");
        int D1T = plugin.getConfig().getInt("Downside1Ticks");
 
        PotionEffect Bonus1 = new PotionEffect(PotionEffectType.getByName(B1),
                B1T, 1);
        PotionEffect Downside1 = new PotionEffect(
                PotionEffectType.getByName(D1), D1T, 1);
 
        // CommandSender player = sender;
        Player player = (Player) sender;
 
        if (cmd.getName().equalsIgnoreCase("SP")) {
            if (args.length == 0) {
                sender.sendMessage("Missing args!");
            }
            if (args.length == 1) {
                if (args[0].equalsIgnoreCase(C1)) {
                    player.addPotionEffect(Bonus1);
                    player.addPotionEffect(Downside1);
                }
 
            }
 
        }
 
        return false;
    }
 
}

What do I need to add for it not to be null without messing up the ability to config the potion effects?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

what if "D1" is something like: "Minecraft" or "Lol" is there a potion effect called "Lol"?

So I need to add an if statement checking what D1 is?

 

Not exactly. Just assuming that if you put something not valid it returned null though this can be modified if it returned an exception:

Code:java

PotionEffect e = null;
e = PotionEffectType.getByName("POTION NAME HERE");
if(e==null) {
//Deal with the error
}

Or if it throws an exception on error you could try:

Code:java

PotionEffect e = null;
try {
e = PotionEffectType.getByName("POTION NAME HERE");
}
catch(Exception e) {
//Deal with the error
}

I'm actually not sure how that function in particular deals with an invalid argument. It may be either of the two solution above. I recommend checking in the online javadocs to see what is says upon invaid potion name.

EDIT: I just checked and it says that it returnes null if type is not found. http://jd.bukkit.org/rb/apidocs/org/bukkit/potion/PotionEffectType.html#getByName(java.lang.String)

 

Thank you so much for the help! I was able to work everything out!
