C# display message in GUI on trigger enter.

I have this script that debug.logs a message when I enter the trigger, there are 3 different messages that can display, depending on the trigger I collide with.

Code (CSharp):

1. public class WeaponStoreRack : MonoBehaviour
2. {
3.     //Creates a Enum and dropdown to select weapon
4.     public enum Weapons {bow=0, sword=1, staff=3};
5.     public Weapons selectedWeapon;
6.    
7.     //when player triggers Rack, get the selected weapon and display msg
8.     void OnTriggerEnter(Collider other)
9.     {
10.         if (other.gameObject.tag == "Player" && selectedWeapon == Weapons.bow)
11.         {
12.             Debug.Log("Ah! The bow! a Ranged weapon to get your foes before they get you! There once was a Archer that could shoot 3 arrows at once! That will be $" + bowPrice);
13.         }
14.        
15.         if (other.gameObject.tag == "Player" && selectedWeapon == Weapons.sword)
16.         {
17.             Debug.Log("Ah! The sword! a Sharp blade to stab your foes with! There once was a Soldier that could slash an entire group of foes at once! That will be $" + swordPrice);
18.         }
19.        
20.         if (other.gameObject.tag == "Player" && selectedWeapon == Weapons.staff)
21.         {
22.             Debug.Log("Ah! The staff! a Light weapon with great reach! There once was a man that could deflect projectiles with a staff! That will be $" + staffPrice);
23.         }
24.        
25.     }
26. }

How do I get the Debug.log msg from this script into the script that goes onto my GUI, so it will display when the trigger conditions are met?

 

Do you have a script for displaying text?

Does the script for displaying text have a method on it to call and tell it a message to display?

If so, get a reference to that script, and OnTriggerEnter call that method.

 

Here is what I have:

this goes onto the WeaponRack, which is basically the shop object

Code (CSharp):

1. public class WeaponStoreRack : MonoBehaviour
2. {
3.     //Creates a Enum and dropdown to select weapon
4.     public enum Weapons {bow=0, sword=1, staff=3};
5.     public Weapons selectedWeapon;
6.    
7.     //Weapon Prices
8.     public int bowPrice = 5;
9.     public int swordPrice = 10;
10.     public int staffPrice = 15;
11.    
12.     //Popup Info message to display
13.     public string bowDisplayMessage = "Ah! The bow! a Ranged weapon to get your foes before they get you! There once was a Archer that could shoot 3 arrows at once! That will be $";
14.     public string swordDisplayMessage;
15.     public string staffDisplayMessage;

the this goes onto the GUI:

Code (CSharp):

1. public class PopupInfo : MonoBehaviour
2. {
3.     public WeaponStoreRack weaponStoreRack;
4.     public string bowMessage;
5.  
6.     void Awake ()
7.     {
8.         weaponStoreRack = GameObject.Find("WeaponRack").GetComponent<WeaponStoreRack>();
9.         weaponStoreRack.bowDisplayMessage = bowMessage;
10.     }
11.    
12.     void Update ()
13.     {
14.         weaponStoreRack.bowDisplayMessage = bowMessage;
15.        
16.         guiText.text = "test " + bowMessage;
17.     }

when I run the game all that shows in the GUI is test and the + bowMessage is nowhere to be seen?

 

I think you wanted to do

Code (csharp):

1. bowMessage = weaponStoreRack.bowDisplayMessage;

instead of the other way around. Currently you are using your empty bowMessage of PopupInfo and are displaying that empty message in your guiText.

Then instead /additionally of a Debug.Log you can input your trigger string into one string variable(currentDisplayMessage) of weaponStoreRack which you can display in you guiText of PopupInfo
