Multiple events into one event
Hello , I made many delegates, (clickA,clickB,clickC... etc...) each touch will trigger an action "destroy()" i have 34 prefabs ( each for a letter in the arabic alphabet) i attached to each letter a script like so : using UnityEngine; using System.Collections;
public class touchA : MonoBehaviour {
void OnEnable()
{
Fly fly = GetComponent<Fly>();
Mainkeyboard.clickA += fly.destroy;
}
void OnDisable()
{
Fly fly = GetComponent<Fly>();
Mainkeyboard.clickA -= fly.destroy;
}
}
So the Question is instead of having to make 34 scripts and then attach each one to a prefab, Am i not able to make one script , that gets attached to prefab and then from a drop down menu(List) and pick which delegate i want?? thank you for your time. here is my main delegate handler.
using UnityEngine;
using System.Collections;
public class Mainkeyboard : MonoBehaviour
{
public delegate void ClickAction();
public static event ClickAction clickA;
public static event ClickAction clickS;
public static event ClickAction clickD;
public static event ClickAction clickF;
public static event ClickAction clickG;
public static event ClickAction clickH;
public static event ClickAction clickJ;
public static event ClickAction clickK;
public static event ClickAction clickL;
public static event ClickAction clickL2;
public static event ClickAction clickL3;
public static event ClickAction clickQ;
public static event ClickAction clickW;
public static event ClickAction clickE;
public static event ClickAction clickR;
public static event ClickAction clickT;
public static event ClickAction clickY;
public static event ClickAction clickU;
public static event ClickAction clickI;
public static event ClickAction clickO;
public static event ClickAction clickP;
public static event ClickAction clickP2;
public static event ClickAction clickP3;
public static event ClickAction clickQ2;
public static event ClickAction clickZ;
public static event ClickAction clickX;
public static event ClickAction clickC;
public static event ClickAction clickV;
public static event ClickAction clickB;
public static event ClickAction clickN;
public static event ClickAction clickM;
public static event ClickAction clickM2;
public static event ClickAction clickM3;
public static event ClickAction clickM4;
}
Why don't you have a single delegate that takes a parameter which is the button pressed?
Considering you have all of your prefabs with the given letter as name then you could simplify by subscribing all of them to one event and the performing a generic check:
public class Mainkeyboard :MonoBehaviour{
public delegate void HandlerEvent(string key);
public static event HandlerEvent OnPress = new HandlerEvent((key)=>{});
void Update(){
// Check if pressed
// pass the press key to the event
if(Input.anyKeyDown)OnPress(Input.inputString);
}
}
public class Touch:MonoBehaviour{
private string givenName;
void Start()
{
givenName = gameObject.name;
Mainkeyboard.OnPress += CheckKey;
}
void CheckKey(string key){
if(key == givenName)// Do what it should
}
// Remember to remove the subscription on destroy
}
Now you may have to work that out a little since Input.inputString works with Ascii and I would think arabic letters are unicode.
Also read the doc as it seems to require a little parsing http://docs.unity3d.com/Documentation/ScriptReference/Input-inputString.html
dude you managed to solve two birds with one stone!!! :D thank you loads!!! , ins$$anonymous$$d of string and given name , i made it into $$anonymous$$eyCode so i can assign each prefab to its own keycode and it works like magic!! thanks again!!!!!!
Declare a public integer and use it to access the event array :
myEvents[eventIndex]();
By "around 30 prefabs", you mean 30 instances of the same prefab right ?
An array of event might not be a good idea actually, System.Action seems to be preferable.
no i have 30 diffrent prefabs ... (Game objects ) consider them as enemies! ( they are letters ) each letter needs its own keyboard input to kill . on a physical keyboard it managed that easy. but for the touch input i made around 30 buttons for each letter ( they are Arabic letters ) each GUI button gives out a OnClicked delegate event , which then destroys the prefab(the letter) so I made one Delegate handler ( $$anonymous$$ainkeyboard) which has the deffrient buttons and Onclicks I want to make one fly script that allows me to handle all the prefabs at once ... but setting which delegate effects which prefab. as i have it right now . i have to rewrite all of the script 30 times and set each delegate to each prefab ... i think having around 30 scripts for each prefab is a bit crazy!
do you have any idea of how i can do it? if it is possible.
