Help with Enter/Exit modified for a turret or cannon in C#

Part of making a game is taking large problems like this and figuring out how exactly to do them. A good way to approach this problem is to break it down into smaller problems, then breaking each of those problems into even smaller problems, until your problems are small enough to handle fairly easily. This is a fundamental component of engineering, and software engineering is a big part of making a game.

This problem you've brought here is broad to ask in a single question or solve in a single answer, but I can help you start on it. Some of the smaller problems that I can see you'd have to break this down into are (in no particular order):

• Detect when a turret is near or in front of the player

• Switch control from the human character to the turret or vice-versa

• Animate the transition into and out of the turret, if necessary

• Stop the human character from physically interacting with things he shouldn't when he's in the turret or mounting/dismounting it

• and anything else you decide that your game requires for this

What I do when I come to a big, overarching problem like this is I write down things I need to do to get it done, finding smaller and smaller things to do until I can't go smaller, until I have a big list of things to work on, then I start doing each of these one at a time. If I think of additional things I need to do or things that would make the game better while I'm doing this, I write those down too, either on my immediate to-do list or "don't forget to do this eventually" list.

Again, the details of you accomplish all of this is up to you. The bullet points above are a good start, but there may be more things you need to account for, or some of the things I mentioned might not apply to your game. Above all, don't be afraid to be creative!

Try your best to break down your problems as small as you can, and give each of your smaller problems your best try, too. The smaller your problems are, the easier they'll be to solve, whether from your own knowledge, or by more clearly seeing what specific bit needs to be googled, or by asking us -- the smaller the problem is, the more detail we can give you in our answers. Coming to us with big problems just gets you long-winded motivational speeches at best, and typically a lot less than that.
