HELP ! Code refuses to compile with no reason

OK, so I was trying to do a paraglider, it uses a Mumech toggle-like way of activating lift, but...

[...]

I really don\'t understand... references are set up correctly, and especially the two first errors... I compiled a plugin with the same 'protected override bool' and it worked fine, and in the MuMech toggle, angularDrag and other game values are never set but they\'re still accepted ?

Please help !

Code does not 'refuse to compile' with no reason.

Look closely and you\'ll see you\'re missing a semicolon.

What\'s a semicolon ? this ? { } ?

(sorry i\'m french)

This: ';'

After onPartActivate(); ?

But there\'s still that deflectionLiftCoeff and parsing error...

You might want to work through a few basic tutorials of C# first before trying to code a plugin...

Basically, every instruction needs to be terminated with a semicolon. On a closer look, your code is missing even more than one.

But there\'s still the 'unexpected symbol deflectionLiftCoeff' error...

Think about what exactly 'deflectionLiftCoeff' is.

[Emilio]

It\'s a variable.

[Corax]

It\'s a variable.

Right. And of what type?

[Corax]

Boolean

And where does it say so?

(Apart from that, I think it ought to be float)

[kellven]

I would have to see the last corrected version of the code to find why it\'s still giving a compile error.

I believe what Corax was saying is that there are no such things as variables. Variables are a concept humans have. Code has no such concept, at least not in 'C' languages. C# is all about classes, which have objects inside them, and the classes themselves are also objects. You can define a custom object of a 'Type', create an 'Instance' of your object type, and assign a 'Value' to an instance of your object. However, those are three separate things you\'re telling the code to do, even if you write it all in a single line.

public class Class1
{
  int a; //define a new Object called 'a' that is a thing of Type 'int'
  protected void functionZ() //define a new Object called 'functionZ', () tells it this is a method thing that does something
  {
    int b; //creates a new Object called 'b' of Type 'int' that exists only inside this {} block, just like 'a' exists only in the class
    b = new int();//This assigns the 'Symbol' or 'Object' 'b' to a new Instance of Type 'int', and gives it a spot in memory
    //C# does the same thing with 'a' when you create an instance of the class, it just doesn\'t show the constructor here
    a = 6; //assign the Value of 6 to the object 'a'
    b = 8; //assign the Value of 8 to the object 'b'
    int c = 5; //does everything above, but is written in a single line. It is still 3 separate steps however.
  }
}

Apologies if I messed that up, or if you already understand this, just trying to be helpful. C# really isn\'t something I\'d suggest jumping directly into if you don\'t know some programming already.

[Corax]

Also, i think Corax is right, it\'s a float.

But where does it say so? The Parachutes class doesn\'t have a member of that name, and you haven\'t declared it anywhere...

[kellven]

If you\'re still trying to find it, you need to look at the class itself, Emilio. I can\'t see what Parachutes is.

[Emilio]

If you\'re still trying to find it, you need to look at the class itself, Emilio. I can\'t see what Parachutes is.

It\'s a game class. By example, if you want to do a command pod, you must type :

class MyCustomPod : CommandPod

Parachutes is the parachute module (don\'t ask me why there\'s an S...).

@Corax : Because a Bool is TRUE/FALSE/AND/OR/NO etc., from the boolean logic.

A float stores a decimal number.

[kellven]

Oops, sorry. Thought it was a custom class, never looked at Parachutes before (and why is it plural?). I see exactly what Corax was saying now.

Use a new line inside onPartActivate(), and type

this.

If you\'re using VisualStudio at least, it\'ll give you a list of members contained in 'this' (make sure you actually type the '.') then try to find 'deflectionLiftCoeff'

[Emilio]

I\'m working on MonoDevelop...

Going to search the correspondant function on the net, but since I haven\'t access to my computer ATM (posting from mobile)...

You\'re right, Parachutes is the only module that is plural...

[kellven]

'this' isn\'t a function, it\'s well, this. Mono may give the same helper popup, if not, you have to look through the declaration of Parachutes, and what Parachutes derives from, and try finding 'deflectionLiftCoeff'. It may also help to look at the declaration of Winglet.

[Emilio]

Not sure i\'ll find deflectionLiftCoeff in the parachutes class, they\'re meant to produce drag, not lift.

And if i find it, what to do next ?

[kellven]

What Corax was saying is that you won\'t find it, because it\'s not a member of Parachutes, or Part. Winglet implements deflectionLiftCoeff, and somewhere in the code we can\'t see, it applies that value as a force to the part. If you want to derive from Parachutes, you need to implement deflectionLiftCoeff yourself, and make it do something with your own code. That can be done, but you can\'t know if it\'s done the same way Squad\'s code does it.

[Emilio]

And have you got any idea how i should do that ?

[kellven]

Depends entirely on what you want it to do, I\'d suggest deriving from winglet and using the game code to handle lift. Otherwise, you\'d need to figure out all the atmospheric AoA drag lift pressure angular velocity stuff yourself. If that\'s what you want to do, all I can do is point you to this:

I managed to work that into actual engine code, but it was a ton of work. The vector is the direction; the length, or magnitude of the vector is the force; and the whole thing belongs in one of the FixedUpdate blocks.

Edit: You could look at how r4m0n switches the models in his Toggle class. The problem is that to use a winglet or control surface base, you have to handle the animation yourself. If you derive from parachute, you have to handle the physics yourself. Going to have to choose one.

[Emilio]

Yes, I could use the winglet class, but if i do this, how do i use the parachute animation ?
