If the actor where the boolean IsDeleted is named Cut , so the reference to the boolean whould be : Cut IsDeleted ? ( ex : if ( Cut IsDeleted == true ) { ....} ) ?
Well, if Cut is the name of the class that creates the actor with the boolean, then Cut is not necessarily, and probably should not be the name of the reference (to avoid confusion). Example: <Code Omitted>With this line, cutActor is the name of the reference to the actor. <Code Omitted>Here,

I rebuit the code for this actor , but after i keep pressing the C button on my keyboard and i lift it at a random moment , i get an weird error << Code Omitted >> I think this error has to deal something with the fact that the compiler cannot find the Actor, but the actor is there
It is not the actor, but the world that it cannot find. Once the actor is removed from the world (line 31), the getWorld method will return a null value. Change lines 31 and 40 to: <Code Omitted>to abort the method when the actor

Hi, I have a question like this I use getIntersectingObjects(Objects.class) to put all Objects into a List. How does the order of the list work? Like if I do get(0) how does it know which is first?
It is probable that they will appear in the list in the same order as they were added into the world.
OHHH I will try it! THANK YOU!

I mean if I launch a missile the missile should be launched from one step down of ship and go in a straight line
To "go in a straight line" is simple. However, "one step down of ship" -- again, not very clear. Explain what this means in detail.

the getMicLevel method does not work. ... I don't know what I am doing wrong. I'm using Windows 10 and version 3.6.1. << Code Omitted >>
There is nothing wrong with the code (tested and works fine -- Windows 7 version 3.1.0). Maybe I should test with an external mic, as well.

I make a space game and I need to have random asteroids spawning on margins and all of them fly randomly.
Length of margin is twice the sum of width plus height minus four. A random pick from length will give a single point along the margin. Converting the random value to a set of coordinates is do-able, but not a simple matter (just takes a little math knowledge).

Or: <Code Omitted> or something along this line: <Code Omitted> The best way would depend on how you create your red and blue cars. That is why it always helps to provide related class codes (and describe your classes structure)
