**only in UActorComponent** and it works when given a locally declared int

- if statements work in character class when given **Local and field int values**
- but in the ActorComponent the if statement works on everything except field declared integers

**is this a but or are ints not supposed to be in if statements**

**this only happens in ActorComponent**

```
if (IntegerValue == 3)
{
	// do something
}
```

Are integers supposed to cause crashes when in if statements

The crash is probably coming from what happens after the if? What does the crash log say?

The crash log just directs me to the exact line the if statement is on

It happens with nothing inside of the if staement

**Could it be because of the int**

But then again it doesnt happen when it is a lacal int **only field**

Hello,

the only way to do such crash is to leave unasigned variable.

make sure you got some value inside this variable. If it crashes right click variable and add watch than check it’s value.

Again make sure you assign value to this variable for example `IntegerValue = 1`

well i did and it still happened

the if statement only causes crash when i use an **int that was declared in the header** even if i set the int value in the **ActorComponents constructor** it still causes crash when in if statement

Have you tried launching a debug instance, e.g. from visual studio `Debug > Start Debugging`, because sometimes it gives more useful information when it catches a crash than the log.
