using my "potion" C#

i am trying to click my Potion button, and add 5 to my player health, and subtract 1 from my current potions.

I have never done anything like this before but i am kind of stuck, and i might just be doing it all wrong, anyways here is what i have. Thanks in advance for the help.

Code (CSharp):

1. private void potionB_Click(object sender, System.EventArgs e)
2.     {
3.         UsePotion();
4.     }
5.    
6.     public void UsePotion(int ptN = 1){
7.         potionL -= ptN;
8.         potionL -= 1;
9.         playerL += 5;
10.         potionText.text = potionL.ToString ();
11.         playerText.text = playerL.ToString ();
12.     }
13.    

 

Well, first thing I see is it appears you're subtracting 1 from potionL twice.
Otherwise, I'm not sure what your question is. Are you getting a bug or is it just not updating?

Is your potionB_Click tied to your button?

 

Well it's not doing anything at all, no errors show up. I click and nothing happens , thanks for the reply.

 

can't be, the "potionB_click" is a private function... might be worth checking out the basics of how to "wire up" the UI button to the function

thx @LeftyRighty i got it to work, only problem im having now is even if the poitions are at 0 i can still click and it will go to a negative number and add it to the health instead of just not working. any suggestions?

 

We add a check to see if we have any potions left, then exit out early if we have zero potions.

Code (csharp):

1. public void UsePotion() {
2.  
3.     // See if we are out of potions.
4.     if (potionL <= 0) {
5.         // No more potions. Do nothing.
6.         return;
7.     }
8.  
9.     potionL -= 1;
10.     playerL += 5;
11.     potionText.text = potionL.ToString ();
12.     playerText.text = playerL.ToString ();
13. }

 

Thanks @Garth Smith i have another question, how could i add a random number generator to another button? i have this right now but it doesnt do anything..

i want this button to subtract that random number from the healthbar...

Code (CSharp):

1.     private void attackB_Click(Button sender, System.EventArgs e)
2.     {
3.         Attack ();
4.     }
5.  
6.  
7.     public void Attack(){
8.  
9.  
10.         {
11.  
12.             System.Random r = new System.Random ();
13.             damageText.text = (r.Next (0, 10).ToString ());
14.             numberGenerated();
15.         }
16.  
17.     }
