Hp on variable and call function

dlevel

Hey!

First of all i am curious if i can call a function directly from ork when i get damaged.

secondly, is there a way to get the HP of my combatant to a variable and use it on a script?

Shadow_Fire

Sure, in your damage battle event, just add a Call Function node and call whatever function you want. To get the Hp of your player into a variable, use the Status Value To Variable node, and to use it on a different custom script, follow what GiL said on this thread, especially click on the api he linked to. Very useful.

Thank you @Shadow_Fire , I cannot seem to find where do I have the damage (so i can put there my damage battle event). Could you please help me on this because I m search for like an hour :P

To store the HP (or any other status value) into a variable, use a Status Value to Variable node. The damage would be done in the battle events used by your actions, i.e. you'll have to do that in the event.

dlevel

yeah i figured that out, i thought maybe there would be a default damage event for the combatant somewhere :)

Thank you guys.

Ok sorry again but i m not any good when comes to scripting stuff.

This is how i get the HP at that time?

What i want to do is having the HP of the exact time so i can use it on a script to cause bleeding etc.

After i get that variable how i call that in my script?

Again sorry but I m no good in scripting and need your help to understand this part here.

I haven't tried it yet, but I'm guessing that it goes along something like this. Feel free to correct me, GiL, or anyone more knowledgeable.

In your script, you have to add the using ORKFramework; up at the top, and then create a float variable, let's call it playerHp. Since you named your variable hpVar, then in your custom script, do playerHp = ORK.Game.Variables.GetFloat ("hpVar"); Now playerHp will have the same value as hpVar.

gamingislove

Yep, that's pretty much it - just make sure the variable names match :)

Ok thank you @Shadow_Fire and GIL!

so this is what i came up with (altering an other script)

but i get this error and the player doesnt load.

NullReferenceException: Object reference not set to an instance of an object ORKFramework.Group.get_Leader () ORKFramework.PlayerHandler.GetPlayer () ORKFramework.GameHandler.GetPlayer () ORKFramework.Behaviours.BaseInteraction.KeyPress () ORKFramework.Behaviours.BaseInteraction.Update ()

using UnityEngine; using System.Collections; using ORKFramework; public class SimplePlayer : MonoBehaviour { [SerializeField] private float HP = ORK.Game.Variables.GetFloat("hpvar"); [SerializeField] private float damageBloodAmount = 3; //amount of blood when taking damage (relative to damage taken (relative to HP remaining)) [SerializeField] private float maxBloodIndication = 0.5f; //max amount of blood when not taking damage (relative to HP lost) public void Damage(int amount) { BleedBehavior.BloodAmount += Mathf.Clamp01(damageBloodAmount * amount / HP); HP -= amount; } }

Don't do that in the initialization of the field: private float HP = ORK.Game.Variables.GetFloat("hpvar"); Get the value from the variable e.g. in the Start function.

dlevel

Sorry I didn't quite understood that :S

I have this script on my player prefab.

edit: did that but doesnt seem to work (added also the maxHpVar to handle the math-the names are correct, changed them). Also am I able to have the hpVar and maxHpVar event node on the game start event? so I have those variables right from the start of the game?

using UnityEngine; using System.Collections; using ORKFramework; public class SimplePlayer : MonoBehaviour { [SerializeField] private float damageBloodAmount = 3; //amount of blood when taking damage (relative to damage taken (relative to HP remaining)) [SerializeField] private float maxBloodIndication = 0.5f; //max amount of blood when not taking damage (relative to HP lost) [SerializeField] float recoverSpeed = 1;//HP per second void Start() { private float maxHP = ORK.Game.Variables.GetFloat("maxHpVar"); private float HP = ORK.Game.Variables.GetFloat("hpVar"); HP = maxHP; }

Shadow_Fire

I'm guessing what GiL meant is that in your script, do -

Private float HP;

Void Start () { HP = ORK.Game.Variables.GetFloat("hpvar");

}

gamingislove

Yes, like that :) Otherwise you'll access ORK long before it's potentially initialized, leading to errors everywhere.

dlevel

Yeap!!! it worked, thank you guys :)

One more Question.

My problem now is that when i kill the enemy, and i rest with the hp regeneration, i dont get the HP Variable so the bleed effect to fade out with time.

Is there anyway to get the HP Variable from somewhere else and not an event from the enemies attack?

Shadow_Fire

Hmm maybe in your regenerate event, after healing, assign again the hp status value to the float value hpvar, and then make sure to let your custom script knows the newly change hpvar.

dlevel

The regenerate is a status effect though.. haven't seen how can i run an event there

gamingislove

Well, you can always hook up to being notified by changes to the status value.

You'll need a function like this in your class: public void StatusValueChanged(Combatant combatant, int id, int change)

Register to changes (e.g. in the Start function): combatant.Status[index].Changed += this.StatusValueChanged; Unregister (do this in the OnDestroy function of the component): combatant.Status[index].Changed -= this.StatusValueChanged; index is the ID/index of the status value.

You can get the combatant of the game object your component is attached to like this: Combatant combatant = ComponentHelper.GetCombatant(this.gameObject); Or, if you just want the player, use ORK.Game.ActiveGroup.Leader.

dlevel

Thank you GIL, this will keep me occupied for the weekend i guess. So if I do this, i no longer need the status value to variable on the events i use now right?

Also if @Shadow_Fire which is very helpful could be more detailed on the script part changes would be really nice :)

This is what i do now, and i only change the BleedBehavior.BloodAmount.

And yes I only need it for my main player.

using UnityEngine; using System.Collections; using ORKFramework; public class SimplePlayer : MonoBehaviour { private float maxHP; private float HP; [SerializeField] private float damageBloodAmount = 3; //amount of blood when taking damage (relative to damage taken (relative to HP remaining)) [SerializeField] private float maxBloodIndication = 0.5f; //max amount of blood when not taking damage (relative to HP lost) void Start() { maxHP = ORK.Game.Variables.GetFloat("maxHpVar"); } void Update() { HP = ORK.Game.Variables.GetFloat("hpVar"); BleedBehavior.BloodAmount = (maxHP - HP) / maxHP; } }
