[Solved] ().Text += 30 problem - PLEASE HELP TO BEGINNER

Hi brothers. In game, for example I have 70 health, I took +30 medicine and it should be 100 but it looks like "7030"
please help me what should I do?

Code (CSharp):

1. canis.GetComponent<Text> ().text += 30;

here is my code

 

When you add a string and an integer in C#, the compiler converts the integer to a string and then concatenates them. So 30 gets converted to the string "30", then "70" + "30" gives "7030", just like "Monkey" + "Wrench" gives you "MonkeyWrench". You could quickly fix your script like this:

Code (CSharp):

1. Text text = canis.GetComponent<Text>();
2. // Parse the string value as an integer
3. int currentHealth = Int32.Parse(text.text);
4. // Add 30
5. var newHealth = currentHealth + 30;
6. // Put the string version of the new health value back into the text component
7. text.text = newHealth.ToString();

However a more robust solution would be to store your health in an actual int value somewhere, and update the text when that value changes using either a property setter or an event.

 

actually I see an int32.parse code first time so I couldnt edit it for myself. and I get a problem
The name `Int32' does not exist in the current context

 

"int" is a type alias for Int32, so you can also just use:

Code (CSharp):

1. int.Parse()

Alternatively, put this at the beginning of your file:

Code (CSharp):

1. using System;

then you can use "Int32"

 

you're incredible!!!!!!!!!
thanks so much
