Im looking for a way to store the same value in two different pointers. Notice THE SAME. Not copies. For example, I wanna have a pointer to what key_a has stored in it. I.e. id like to be able to do something like this:

Code:

---

typedef struct
{
   var jump;
   [...]
} KEYMAPPING;

[...]

KEYMAPPING* my_key_mapping =
{
   jump = &key_w;
}

---

Is it possible to achieve this somehow? Lite-c doesnt seem to support C/C++'s adress-of operator &.

Lite-C does support the address of operator. What problem are you having with it?

You might also want to look up key_set () in the manual. It's made for keyboard remapping.

After a closer look, yeah it seems like lite-c supports it. However it didnt solve my problem. Now when I declare a var* that points to &key_w, the program crashes. For example this will crash the program:

var* lol = &key_w; (if global, and if initialized within function it still crashes.)

key_set does not suffice, since im checking keys every frame.
Maybe the key_w isnt a var? It says flag in manual, but there is no type FLAG so i dunno what to do.

Maybe key_w is a bool? I don't know. Or maybe it's not possible to get the address of engine variables..

You should indeed set it up in a function.

I don't understand why you can't use key_set..

void jumpEvent(){key_mapping.jump = TRUE;}
then use key_set to fire jumpEvent when a certain key is pressed.

Jump is a bad example, even though the way I wanna use it cannot be done with simply a function, its too hard for me to explain in english (and Ive already completed it anyway, what Im doing now is just trying to seperate the mapping so it can be changed easily).

But otherwise movement cannot be done with simply a function for each key. Only if youd have an key_up/mouse_up event, and afaik there is no such thing in lite-c.

So for example if I want my avatar to move left as long as i keep my A key pressed, that cannot be done with key_set, right? Then Id have to use if(key_a), and as I said, Id rather use something like my_key_mapping.key_left (key_jump, key_run etc) or something ... Also, im using gamepad joysticks for movement, so its pretty much not possible to do that anyway (I guess?)

Hi Kenchu!

I use the c_move :

Code:

---

c_move (my,vector(10 * (key_w - key_s) * time_step, 6 * (key_a - key_d) * time_step, 0),
		nullvector, IGNORE_MAPS | ACTIVATE_TRIGGER | IGNORE_CONTENT | USE_BOX | GLIDE | IGNORE_PASSABLE); //

Will this help.

Hehe this wasnt really what I was asking about. But thx anyways.

I wanna get rid of things such as key_a, key_b. I dont wanna hard-code keys to do specific things. Id rather have a variable, for example key_jump, that can change, but the code remains the same.

Just use key_pressed(x) and a variable with the scancode. That's easier

Ah excellent. That will do.
And now my mapping will work aswell.

Oh and thx.
