Splitting Config String

So, I'm using this to create an entity and give it multiple metadatas(through config) once spawned. Everything worked find til I started using a seperator and began splitting everything, so Creeper spawned fine, but Creeper|metadatakey;value returns a nullpointerexception.

MobData Class

Code:java

import java.util.Map;
 
import org.bukkit.entity.EntityType;
 
public class MobData {
    protected final EntityType type;
    protected Map<String,String> metadata = null;
public MobData(String full){
    String[] splits = full.split("|");
    if(splits!=null){
        if(splits.length>1){
            String[] metas = splits[1].split(",");
            if(metas!=null){
                for(String thisMeta:metas){
                    String[] metawithvalue = thisMeta.split(";");
                        if(metawithvalue.length>1){
                            metadata.put(metawithvalue[0], metawithvalue[1]);
                    }
                }
            }
        }
 
 
    }
    this.type = EntityType.fromName(splits[0]);
}
public EntityType getEntityType(){
    return this.type;
}
public String getMetaValue(String string){
    return this.metadata.get(string);
}
public Map<String,String> getMetaData(){
    return this.metadata;
}
}

SpawnLocation Class

Code:java

public class SpawnLocation extends BlockLocation {
 
    private MobData creatureType;
 
    public SpawnLocation(World world, int x, int y, int z) {
 
        super(world, x, y, z);
 
    }
 
    public void setCreatureType(MobData mobData) {
 
        this.creatureType = mobData;
 
    }
 
    public LivingEntity spawnCreature() {
        LivingEntity thisEntity = (LivingEntity) world.spawnEntity(new Location(world,x,y,z), creatureType.getEntityType());
        Map<String,String> metas = creatureType.getMetaData();
        if(metas!=null){
        for (Entry<String, String> entry : metas.entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            thisEntity.setMetadata(key, new FixedMetadataValue(Bukkit.getServer().getPluginManager().getPlugin("Quarantine"), value));
        }
        }
        return thisEntity;
    }
}
 

Line 35: LivingEntity thisEntity = (LivingEntity) world.spawnEntity(new Location(world,x,y,z), creatureType.getEntityType());(NullPointerException)

Some example strings that are instantiated as MobData(from config).
mob_types:
- 'Zombie|super_speed;true'(doesn't work)
- 'Spider|displayname;Timone,super_speed;true'(doesn't work)
- 'Skeleton'(works)

 

Fl1pzta In java, use "\\|" if you want to split on "|"

 

same with ":"?

 

Fl1pzta Yes, for ":" just use "\\:"

 

To be honest, I do not get why people do this. Same issue as this one. Just make proper use of the YAML file instead of splitting strings & stuff.

 

What are these considered? Reservered regex characters or something

It feels quicker to me lol
