I mean just this line: As it doesn't make any sense to just put 'if (...)' around it... How could that be a condition?

I have no idea when it comes about programming in the past i managed to get it fast now i lose my patience and quit like everything i'm near quiting this idea soon and however never try work on this engine again idk...

I actually did that in past but i have no idea how in 1 month of break 1 year ago i just cannot understood and yeah i quit the boss idea just keep up the score thing to fix and mhm never come back here...

You need to explain what YOU want as far as when and how the boss is to shoot bullets. What rate of fire (or what delay between shots)? Are the shots to be fired at a regular rate or with some randomness to it? Is there a certain range that is required between the boss and the chased before a shot is even fired? Everything that deals with the boss shooting bullets must be provided (or at least determined) before the appropriate conditions can be encoded to regulate the firing of bullets.

Just shoots some bullets like 1 or 2 at 2 seconds wich will remove the "chased" or send him to a world that says he lost... I only need an example of him and working not the complex part.... All i asked was that class of actor called "Chaser" to be duplicated and had the option to shoot some bullets not even at a speed or even detailed thing just a normal demo of a boss that shoots the bullets randomly or even to the chased...

You can use a simple condition like the following, then:
