How to set a queue for dragons?

[Kumkfat]

I want my dragons to spawn in order from weakest to strongest. When i use weight system in this plugin for example. Dragon1 has weight 1 and Dragon2 has weight 2 it just spawns randomly.

Yes, you are right.
Currently the plugin cannot specify exactly what the next dragon's type is. I think your advice is good, but it is unfortunate that this function depends on persistent data storage(for example, database) which are to be implemented.

But if you take groovy script into consideration, maybe it will be easy.
I can update some code of plugin and then show you an example.

(1) Decompress "dragon_type_decider.zip", you will get a groovy script.
(2) Reverse the unique_name of groovy script to adapt to your configuration.("zero","one","two","three","the 100th dragon",etc)
(3) Ensure you are using EnderDragon 2.4.0+

Note: The groovy script engine is disabled in default.

dragon_type_decider.groovy:

import groovy.transform.Field
import pers.xanadu.enderdragon.event.DragonRespawnPostEvent
import pers.xanadu.enderdragon.manager.DragonManager
import pers.xanadu.enderdragon.metadata.DragonInfo
import pers.xanadu.enderdragon.script.Events

static @Field List<String> list = ["zero","one","two","three"]

static void enable(){
    Events.register(DragonRespawnPostEvent.class, e->{
        DragonInfo info = e.getDragonInformation()
        String unique_name = info.unique_name
        int id = DragonManager.getCount()
        if(id==100){
            unique_name = "the 100th dragon"
        }
        else if(id==500){
            unique_name = "the 500th dragon"
        }
        else{
            unique_name = list[id % 4] //id mod 4. (100->"zero", 101->"one", 150->"two")
        }
        //set to the DragonInfo object, the change applies
        info.unique_name = unique_name
    })
}
