Variables not setting correctly
Hello,
I've got a few variables
public int health;
private int test = 10;
Changing it in the Start function
public void Start()
{
test = health;
Debug.Log("test: " + test);
}
Which displays: 1, as intended. But later when I try to log the variable again, I get an incorrect number.
public void Touch()
{
Debug.Log("test: " + test);
}
Displays: 10.
If I change this variable to 20. The Touch function will still display 10, until I re-open Unity.
What is happening...?
Are you sure this is your exact code? The problem you describe would happen if on 3 in your start section you had this ins$$anonymous$$d:
int test = health;
public int health = 100;
private int test = 10;
void Start() {
//changing test value to health
test = health
//print log
print("Health is about " + test.ToString());
//Output should be (Health is about 100)
//whenever you print it its value same as health
}
If the variable is public, it will allways get the int you setted in the inspector.
The full class:
public class $$anonymous$$oleObject: $$anonymous$$onoBehaviour
{
public int health;
private int test = 200;
public void Start()
{
test = health;
Debug.Log("Test 2: " + test);
}
public void Touch(int mod)
{
Debug.Log("Test: " + test);
}
}
The variable 'test' was set on the first run, changing the variable later won't change anything.

Note that changing health in the inspector won't change test after that Start was called. integers are passed by value, not by reference
I ran into a similar situation just now. It turned out I was only changing my public variable on a single instance of a prefabbed object in the editor, when I wanted to change it on the prefab itself, leading to a lot of confusion. Is this perhaps what you're doing as well?
This was a while ago, sorry for not answering how I fixed it. But my problem was that I was setting the variable of the prefab ins$$anonymous$$d of the create object. This caused unwanted behaviour. Why this behaviour happend I don't know, it could be a bug in Unity.
I'm going to mark this as the answer, so people know what the solution is :)
Since your health variable is empty, the test variable doesn't know what to be set to, so you'll need to enter a value in the health variable for it to work.
The health variable is set in the unity editor. But that's not the point... I already set in the post that health and test output the correct number: 1. But after the start function test outputs a completely number.
@Bio Discus, sorry but that last sentence doesn't make any sense. Could you try reformulating your sentence or if you are having trouble translating from a different language write both what you want to say in your mother tongue and google-translate's result?
Sorry for that.
The health variable is set in the unity editor to 1. The test variable is set to the health variable in the Start function, this logs: 1 (test = health). But in the Touch function the test variable behaves weirdly, it outputs a completely different number (See this image: http://gyazo.com/dc86717e1cd4efa2a2622c924866e6d9.png).
I just checked the log inside the Update function, and everything logs as it should be logged. Is it possible there is a problem with the function: GetComponent(); ?
Please show us the code you are using for your GetComponent() call.
