C# Health Bar please help

Hello,

I am currently trying to create a health bar which i managed to do, however every time i touch the wall all of the health goes which is bad. What i want it to do is to take 10 hits to the ball before it becomes destroyed, if anyone got a script that i can follow or an example that would be great.

I hope you can follow my code as i am new to this

thank you
here is the code

Code (CSharp):

try this:

Code (CSharp):

1. void OnCollisionEnter(Collision other)
2.     {
3.         //this is when i touch the ground i am able to jump but i will add the 5 second delay lyaer
4.         if (other.gameObject.CompareTag("ground"))
5.         {
6.             onGround = true;
7.         }
8.        //heath section
9.         if(other.gameObject.CompareTag("Wall"))
10.         {
11.             healthBar.value -= 0.1f;
12.         }
13.         if(healthBar.value <= 0)
14.         {
15.             Destroy(gameObject);
16.         }
17.     }

 

Not sure if you have this but make sure you set the slider's max value to 100 before decrementing the value. Otherwise you're just subtracting 1 from 1.

 

Thank you guys i have got it working i appreciate all your help
